Definitions
- the invention disclosed herein relates generally to inhibitors of novel, functional GPCR heteromers, and more specifically to inhibitors of CXC receptor 4 (CXCR4)-G protein-coupled receptor (GPCR) heteromers that display enhanced signaling downstream of CXCR4 as a result of functional heteromer formation and that are associated with cancers and other diseases.
- CXCR4 CXC receptor 4
- GPCR G protein-coupled receptor
- G protein-coupled receptors are seven-transmembrane domain cell surface receptors that are coupled to G proteins. GPCRs mediate diverse sensory and physiological responses by perceiving stimuli including light, odorants, hormones, neurotransmitters, chemokines, small lipid molecules, and nucleotides. There are approximately 800 GPCR genes in human genome, and more than half of them are predicted to encode sensory receptors such as olfactory, visual, and taste receptors (Bjarnadottir, et al., 2006).
- GPCRs have physiologically important roles in embryonic development, behavior, mood, cognition, regulation of blood pressure, heart rate, and digestive processes, regulation of immune system and inflammation, maintenance of homeostasis, and growth and metastasis of cancers (Filmore 2004, Overington, et al., 2006). GPCRs are associated with many diseases and are the targets of approximately 40% of all prescription drugs (Filmore 2004).
- CXC receptor 4 is a member of the chemokine receptor family GPCR.
- CXCR4 is expressed on most of the hematopoietic cell types, bone marrow stem cells, endothelial progenitor cells, vascular endothelial cells, neurons and neuronal stem cells, microglia and astrocytes (Klein and Rubin 2004, Griffith, et al., 2014).
- CXCR4 responds to its ligand C-X-C Motif Chemokine ligand 12 (CXCL12), also known as Stromal cell-derived factor 1 (SDF-1), and has essential roles in the embryonic development of the hematopoietic, cardiovascular, and nervous systems (Griffith, et al., 2014).
- CXCR4 was discovered as a co-receptor for human immunodeficiency virus (HIV), and has important roles in the homing of hematopoietic stem cells (HSCs) to the bone marrow, inflammation, immune surveillance of tissues, and tissue regeneration in adult (Chatterjee, et al. 2014). Mutations in the C-terminus of CXCR4 cause persistent CXCR4 activation, leading to a congenital immune deficiency called WHIM syndrome (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis) characterized by neutropenia and B cell lymphopenia (Hernandez, et al., 2003; Kawai, 2009). CXCR4 also has essential roles in T and B lymphocyte development within lymphoid organs and the thymus during development and in adult (Allen, et al., 2004; Ara, et al., 2003).
- HCV human immunodeficiency virus
- CXCR4 is implicated in various immune and autoimmune diseases, such as HIV infection, ischaemia, wound healing, rheumatoid arthritis, systemic lupus erythematosus (SLE), interstitial pneumonias, vascular disease, multiple sclerosis, pulmonary fibrosis, and allergic airway disease (Chu et al., 2017; Debnath, et al., 2013; Domanska, et al., 2013).
- autoimmune diseases such as HIV infection, ischaemia, wound healing, rheumatoid arthritis, systemic lupus erythematosus (SLE), interstitial pneumonias, vascular disease, multiple sclerosis, pulmonary fibrosis, and allergic airway disease (Chu et al., 2017; Debnath, et al., 2013; Domanska, et al., 2013).
- CXCR4 The involvement of CXCR4 in rheumatoid arthritis was demonstrated by the increased accumulation of CXCR4-positive T-cells in arthritic joints, and a reduction in collagen-induced arthritis in CXCR4-deficient mice (Buckley et al., 2000; Chung et al., 2010). Moreover, CXCR4 antagonist, AMD3100, alleviated collagen-induced arthritis significantly in a mouse model (De Klerck et al., 2005). CXCR4 also regulates pulmonary fibrosis by recruiting circulatory fibroblasts and bone marrow-derived progenitor cells during lung injury, and AMD3100 demonstrated a preventive effect in bleomycin-induced mouse pulmonary fibrosis (Song et al., 2010).
- CXCR4/CXCL12 axis is also implicated in the pathogenesis of SLE.
- inflammatory cells such as monocytes, neutrophils, and B-cells showed increased expression of CXCR4 and migrated toward skin and lung that overexpress CXCL12 predominantly (Chong and Mohan, 2009; Wang et al., 2009; Wang et al., 2010).
- CXCR4 is also involved in brain and cardiac diseases including brain injury, stroke, myocardial infarction, atherosclerosis and injury-induced vascular restenosis (Cheng et al., 2017; Domanska, et al., 2013; Doring, et al., 2014).
- CXCR4 chronic lymphocytic leukemia
- CXCR4 is subsequently characterized to be responsible for breast cancer metastasis to organs that express higher levels of CXCL12 such as lymph nodes, bone marrow, lung, and liver (Muller, et al., 2001). After initial discovery, increasing evidence indicates that CXCR4 is associated with a variety of different cancers and has multiple potential roles in malignancy.
- CXCR4 is overexpressed in more than 23 human cancers, including breast cancer, lung cancer, brain cancer, kidney cancer (or renal cell carcinoma), pancreatic cancer, ovarian cancer, prostate cancer, melanoma, leukemia, multiple myeloma, gastrointestinal cancers, and soft tissue sarcomas, and regarded as a poor prognosis marker (Domanska, et al., 2013; Chatterjee, et al., 2014; Furusato et al., 2010).
- CXCR4 is the only chemokine receptor that is expressed by the majority of cancer types (Liang et al., 2015), and stimulates tumor cell growth, survival, and invasiveness in response to CXCL12 secreted by the cancer cells and the surrounding cancer-associated cells (Burger and Kipps, 2006; Chatterjee et al., 2014; Domanska et al., 2013).
- CXCR4/CXCL12 axis plays a central role in tumor growth, invasion, angiogenesis, vasculogenesis, metastasis, drug resistance, and cancer cell-tumor microenvironment interaction (D'Alterio et al., 2012; Domanska et al., 2013; Guo et al., 2016)
- CXCR4 critical role of CXCR4 in cancer cell proliferation and tumor growth was demonstrated in various experimental models in vitro and in vivo such as orthotopic, subcutaneous human xenograft, and transgenic mouse models using CXCR4 antagonists (Domanska et al., 2013).
- the Daoy medulloblastoma cells and U87 glioblastoma cells showed CXCR4 expression and exhibited dose-dependent increase in proliferation to a gradient of CXCL12 in vitro , and systemic administration of AMD3100 inhibited the growth of intracranial U87 and Daoy cell xenografts (Rubin et al., 2003).
- the main mechanism of action described for the small molecules or peptides antagonists of CXCR4 is centered on their ability to mobilize malignant cells from the BM, thereby sensitizing them to chemotherapy. These agents have shown limitations regarding short half-lives, making their adequate management over long periods of time difficult (Hendrix et al., 2000). In contrast, therapeutic monoclonal antibodies have the advantage of having more prolonged half-lives, and are suitable for less frequent dosing. Additionally, human IgG antibodies have the ability to induce cell death upon binding to their target protein on cancer cells, via interaction with Fc-receptor on effector cells, including antibody-dependent cell mediated cytotoxicity/phagocytosis (ADCC/ADCP) (Jiang et al., 2011). Such cytotoxic mechanism of action are not inherent to small molecules or peptides, and have been demonstrated to play a key role in the clinical activity of several therapeutic antibodies (Wang et al., 2015).
- CXCR4 using a neutralizing anti-CXCR4 antibody or CXCR4 specific antagonists inhibited primary tumor growth as well as metastasis to secondary organs in breast cancer, colon cancer, hepatocellular carcinoma, osteosarcoma, and melanoma (De Falco et al., 2007; Hassan et al., 2011; Huang et al., 2009; Kim et al., 2008; Muller et al., 2001; Schimanski et al., 2006; Smith et al., 2004; Zeelenberg et al., 2003).
- Cancer stem cells are a population of cancer cells with properties such as infinite self-renewal, potential to differentiate into multiple cancer lineages, ability to adopt a quiescent state, and intrinsic high resistance to chemo- and radio-therapy. CSCs are considered as the major cause of cancer relapse and recurrence after standard anti-proliferative therapy. Therefore, targeting cancer stem cells are expected to provide more effective therapeutic interventions to eradicate the cancer and prevent relapse (Batlle and Clevers, 2017; Reya et al., 2001; Wurth, 2016).
- CSCs also express CXCR4, and CXCR4 directs the trafficking and metastasis of these cells to the CXCL12-rich microenvironments such as bone marrow and subventricular zone in the brain that favor cancer stem cell maintenance, survival and growth.
- CXCR4 antagonists have been shown to mobilize CSCs from these protective microenvironments, and sensitize them to conventional chemo- and radiotherapy, and anti-angiogenic therapy (Burger and Kipps, 2006; Burger and Peled, 2009; Furusato et al., 2010; Redondo-Munoz et al., 2006; Walenkamp et al., 2017; Wurth, 2016).
- tumor mass contains various cell types such as stromal fibroblasts, immune cells, endothelial cells, connective tissue, and extracellular matrix in addition to cancer cells that constitute tumor microenvironment (TME) or cancer cell niches.
- CXCR4/CXCL12 axis plays pivotal roles in tumor cell-microenvironment interaction that support tumor structure, growth, angiogenesis, and evasion of immune surveillance in various cancers of both the hematopoietic and nonhematopoietic system (Burger and Kipps, 2006; Burger and Peled, 2009; Walenkamp et al., 2017).
- CXCL12 can promote tumor angiogenesis by recruiting endothelial cells to the TME directly, or indirectly by attracting CXCR4-positive inflammatory cells to the tumor mass, and making them to secret proangiogenic factors (Owen and Mohamadzadeh, 2013; Walenkamp et al., 2017).
- VEGF Vascular endothelial growth factor
- bevacizumab increased the expression of CXCL12 and CXCR4 in cancer cells, and increased plasma levels of CXCL12 in these patients were associated with rapid disease progression and metastasis (Owen and Mohamadzadeh, 2013; Xu et al., 2009).
- CXCR4/CXCL12 axis has been demonstrated to disrupt the tumor microenvironment (TME) and expose the tumor cells to immune attack by decreasing the infiltration of myeloid-derived suppressor cells, by increasing the ratio of CD8+ cytotoxic T cells to Treg cells, or eliminating tumor re-vascularization (Burger et al., 2011; Domanska et al., 2013; Walenkamp et al., 2017).
- CXCR4 antagonists AMD3100 or T22
- immune checkpoint inhibitors such as cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) antibodies, programmed cell death protein 1 (PD-1), and programmed cell death ligand 1 (PD-L1) antibodies and greatly increased their antitumor activity in a model of pancreatic ductal adenocarcinoma, advanced hepatocellular carcinoma (HCC), and CXCR4-transduced B16 melanoma (Chen et al., 2015; Feig et al., 2013; Lee et al., 2006; Scala, 2015; Walenkamp et al., 2017).
- CXCR4/CXCL12 axis offers benefit to the conventional immune checkpoint inhibitors.
- CXCR4 inhibitors can be divided into 5 categories:
- non-peptide small molecule antagonists such as AMD3100 (plerixafor, MozobilTM, Genzyme (MA, USA); (Cashen et al., 2007; Donzella et al., 1998), AMD070 (AMD11070; Crawford and Alan Kaller, 2008; Stone et al., 2007), AMD3465 (Genzyme Corp., Biochem Pharmacol.
- small-peptide antagonists such as anti-HIV peptides T22 (Masuda et al., 1992), T134 and T140 (Tamamura et al., 1998), BKT140 (a/k/a BL-8040; TF14016; 4F-Benzoyl-TN14003, Biokine Therapeutics Ltd.
- CXCR4 antibodies to CXCR4, such as ulocuplumab (MDX1338/BMS-936564; Kuhne et al., 2013), PF-06747143 (Pfizer; Liu et al., 2017), 12G5 (Endres et al., 1996), i-bodies (AD-114, AD-114-6H, AD-114-Im7-FH, and AD-114-PA600-6H; AdAlta; Griffiths et al., 2016; Griffiths et al., 2018), nanobodies (238D2 and 238D4; Jahnichen et al., 2010; Proc. Natl Acad. Sci. 2010, USA 107(47), 20565-20570), and ALX-0651 (Ablynx, biparatopic nanobody, ClinicalTrials.gov Identifier: NCT01374503);
- CXCL12 ligand (CXCL12) analogs with suppressive activity, such as CTCE-9908 (Chemokine Therapeutics (BC, Canada); Wong et al., 2014); and
- radiolabeled CXCR4 ligands such as [99mTc]O2-AMD3100 (Hartimath et al., 2013), [68Ga]pentixafor (Demmer et al., 2011; Gourni et al., 2011), [177Lu]pentixather, and [90Y]pentixather (Herrmann et al., 2016).
- AMD3100 JM 3100, plerixafor, marketed as Mozobil is a CXCR4-specific small molecule antagonist that inhibits CXCL12-mediated calcium mobilization and chemotaxis in various cell types (Hatse, Princen et al. 2002), and prevents tumor growth in mouse xenograft models (Rubin, Kung et al. 2003, Cho, Yoon et al. 2013, Liao, Fu et al. 2015). AMD3100 was originally developed for HIV therapy (as an HIV entry blocker that specifically antagonizes CXCR4, one of the HIV entry co-receptors), but was approved by the U.S.
- AMD3100 for HIV therapy was suspended due to significant side effects including thrombocytopenia, premature ventricular contractions, and leukocytosis following long-term inhibition of CXCR4/CXCL12 axis (Hendrix, et al., 2004; Peled, et al., 2012). Although investigating the possibility of the use of AMD3100 as an anticancer drug is underway, lack of oral availability and some severe side effects accompanying with long-term use need to be overcome (Peled, et al., 2012).
- subcutaneous AMD3100 was approved in combination with G-CSF for autologous stem cell mobilization and transplantation for patients in the US with non-Hodgkin lymphoma (NHL) or multiple mylenoma for up to 4 consecutive days, and for patients in Europe with multiple mylenoma or lymphoma for 2-4 consecutive days and for up to 7 consecutive days, respectively (DiPersio et al., 2009a; DiPersio et al., 2009b; Keating, 2011). So far, AMD3100 is the only CXCR4 antagonist approved by the FDA.
- AMD3100 has been shown to inhibit CXCL12-mediated calcium mobilization and chemotaxis in various cancer cell types expressing CXCR4 (Hatse et al., 2002), and has demonstrated significant anti-tumor activity with decreased metastasis and increased overall survival in various mouse xenograft models (Burger et al., 2011; Chatterjee et al., 2014; Cho et al., 2013; Debnath et al., 2013; Domanska et al., 2013; Liao et al., 2015; Rubin et al., 2003; Walenkamp et al., 2017).
- AMD3100 exhibits partial agonism for CXCR4 in vitro and increases the proliferation of meloma cells (Kim et al., 2010; Zhang et al., 2002). AMD3100 also acts as a positive allosteric modulator of CXCR7, an alternative chemokine receptor for CXCL12, and increases CXCL12 binding to CXCR7 (Kalatskaya et al., 2009). Like CXCR4, CXCR7 is also highly expressed by many types of cancers and is associated with tumor metastasis (Decaillot et al., 2011; Zabel et al., 2011). Due to the complex properties of AMD3100, the exact role of AMD3100 on cancer needs to be investigated carefully.
- AMD3100 has been clinically evaluated as anticancer drug in combination with conventional cytotoxic drugs such as mitoxantrone, etoposide, cytrabine, daunorubicin, azacitidine, lenalidomide, decitabine, clofarabine, fludarabine, and/or idarubicin; receptor tyrosine kinase inhibitors AC220 and sorafenib; HSP90 inhibitor (Ganetespib); G-CSF; proteasome inhibitor (bortezomib); or monoclonal antibody (rituximab) in hematological malignancies including acute myeloid leukemia (AML), MM, Myelodysplastic Syndromes (MDS), CLL, and small lymphocytic lymphoma (SLL) (ClinicalTrials.gov Identifier: NCT00512252, NCT00694590, NCT00903968, NCT00990054, NCT01065129,

- BKT140 is in Phase II clinical trials for interfering tumor microenvironment interaction in subjects with AML in combination with cytarabine (ClinicalTrials.gov identifier: NCT02502968).
- CTCE-9908 (Chemokine Therapeutics Corp., Canada), a peptide inhibitor of CXCR4, reduced metastases in mouse models of osteosarcoma and melanoma (Kim et al., 2008).
- CTCE-9908 was designated as an orphan drug for the treatment of osteosarcoma by the FDA in 2005. There is no further development after phase I/II clinical trial has been completed in 2008 (Debnath, et al., 2013).
- MSX-122 (Altiris Therapeutics), a small molecule CXCR4 antagonist, has been abandoned after clinical trial in patients with solid tumors (ClinicalTrials.gov identifier: NCT00591682). Two major setbacks have been reported in 2017 in the field of developing CXCR4 antagonists as anti-cancer drugs.
- BMS-936564 / MDX1338, (Kuhne et al., 2013), a fully human anti-CXCR4 antibody, in patients with solid tumors for lack of efficacy (https://seekingalphacom/article/4057548-bristol-failure-makes-small-dent-cxcr4-blocking-approach?page 2).
- Eli Lilly decided to abandon a few anti-cancer programs including LY2510924, which is a CXCR4 peptide antagonist (http://wwwfiercebiotechcom/biotech/lilly-puts-two-thirds-mid-phase-cancer-pipeline-up-for-sale-major-shake-up-r-d-priorities) after a series of clinical trials in solid tumors (ClinicalTrials.gov identifier: NCT02737072, NCT01391130, and NCT01439568). These events indicate that development of CXCR4 antagonists as anti-cancer drugs, especially for solid tumors, is an ongoing challenge.
- USL311 (Upsher-Smith) is under phase I and phase II in patients with solid tumors and glioblastoma multiforme (GBM), respectively (ClinicalTrials.gov identifier: NCT02765165); GMI-1359 (Glycomimetics) is in phase I trial (ClinicalTrials.gov identifier: NCT02931214).
- PF-06747143 (Pfizer), a humanized anti-CXCR4 antibody, is in phase I clinical trial in patients with AML either alone or combined with chemotherapy (ClinicalTrials.gov identifier: NCT02954653, (Liu et al., 2017)).
- AD-114 (i-body, AdAlta; (Griffiths et al., 2018) is a humanized shark anti-CXCR4 antibody and received orphan drug designation from united states FDA for a drug candidate used for treatment of Idiopathic Pulmonary Fibrosis in 2017 (https://www.reuters.com/article/idUSFWN1F70Y0).
- AD-114 study is mainly focused on fibrotic conditions, including wet age-related macular degeneration and non-alcoholic fatty liver disease (https://lungdiseasenews.com/2017/08/23/adalta-present-research-on-investigative-therapy-ad-114-at-ipf-summit/).
- POL6326 (balixafortide, Polyphor), a peptide CXCR4 antagonist, has been under clinical evaluation in subjects with breast cancer (ClinicalTrials.gov identifier: NCT01837095), hematologic malignancies (ClinicalTrials.gov identifier: NCT01413568), and stem cell mobilization and healing in patients with acute myocardial infarction (ClinicalTrials.gov identifier: NCT01905475).
- Radiolabeled CXCR4 ligands such as [99mTc]O2-AMD3100 and [68Ga]Pentixafor has been used for preclinical or clinical SPECT or PET imaging of CXCR4 expression (Demmer et al., 2011; Gourni et al., 2011; Hartimath et al., 2013; Walenkamp et al., 2017).
- PET imaging with [68Ga]Pentixafor has demonstrated increased expression of CXCR4 not only in hematologic and solid tumors such as leukemia, lymphoma, MM, adrenocortical carcinoma, and SCLC, but also in other pathological conditions such as splenosis, stroke, atherosclerosis, and myocardial infartion (Walenkamp et al., 2017).
- a peptide CXCR4 ligand labeled with ⁇ - or ⁇ -emitters has been tested in more than 30 therapies as CXCR4-directed endoradiotherapy together with standard chemotherapy in patients with hematologic malignancies (Walenkamp et al., 2017).
- CXCR4 antagonists are administered with cytotoxic drugs or radiotherapy, HSCs mobilized into periphery would be exposed to the effects of cytotoxic treatment which could exacerbate cytopenias. Cardiac complications observed in patients treated with AMD3100 also raised general concern in prolonged use of CXCR4 antagonists as anticancer drugs.
- GPCR heteromers offer new possibilities for developing more specific and disease-restricted therapeutics.
- GPCRs were considered to be monomeric since monomeric GPCRs can activate G proteins by inducing conformational changes of the heptahelical domain upon ligand binding (Pin et al., 2008; Okada et al., 2001).
- increasing evidence demonstrates that GPCRs may form oligomers, either homo- or hetero-oligomers, and GPCR heteromers can exhibit specific properties that clearly distinguish them from existing well-defined monomers, such as signaling pathways, ligand binding affinities, internalization, and recycling (De Falco et al., 2007; Ferre et al., 2010; Gomes et al., 2016).
- GPCR oligomerization may provide a way to increase the diversity of GPCR entities with a limited number of genes (Park and Palczewski, 2005).
- identification of novel GPCR heteromers would offer new possibilities for understanding the roles of GPCR heteromers in specific tissues and in specific diseases, as well as providing new opportunities for developing more efficient therapeutics with less side effects.
- CXCR4 also forms heteromers with different GPCRs. So far CXCR4 is known to interact with GPCRs in the chemokine receptor family (CCR2 (Rodriguez-Frade et al., 2004; Sohy et al., 2007; Sohy et al., 2009; Armando et al., 2014), CCR5 (Agrawal et al., 2004; Rodriguez-Frade et al., 2004; Sohy et al., 2007, Sohy et al., 2009; Martinez-Munoz et al., 2014), CXCR3 (Watts et al., 2013), and CXCR7 (Sierro et al., 2007; Levoye et al., 2009; Decaillot et al., 2011)), chemerin chemokine-like receptor 1 (CMKLR1) (de Poorter et al., 2013), ⁇ -opioid receptor (OPRD) (P
- ADRA1A Tripathi et al., 2015
- ADRA1B Tripathi et al., 2015
- ADRB2 LaRocca et al. 2010; Nakai et al., 2014
- CXCR4-CCR2 and CXCR4-CCR5 heteromers were first noticed by studying HIV infection.
- Rodriguez-Frade et al. showed that CCR2-01, a CCR2-specific monoclonal antibody, did not compete with CCL2 for binding to CCR2 or trigger CCR2 signaling, but blocked replication of monotropic (R5) and T-tropic (X4) HIV strains by inducing oligomerization of CCR2 with CCR5 or CXCR4 (Rodriguez-Frade et al., 2004).
- CCR5D32 specifically inhibited CCR5 and CXCR4 cell surface expression by heteromerization with CCR5 and CXCR4, thereby inhibiting HIV coreceptor activity of CCR5 and CXCR4 in CD4+ cells.
- Co-expression of CCR5 was shown to prevent HIV-1 gp120 binding to the cell surface and to reduce X4 HIV-1 infectivity by inducing CCR5-CD4-CXCR4 oligomerization and conformational changes in CD4 and CXCR4 (Martinez-Munoz et al., 2014).
- Sohy et al. reported the existence of negative binding cooperativity between the subunits of CXCR4-CCR2 and CXCR4-CCR5 heteromers, i.e. the ligands of one receptor competed for the binding of a specific tracer of the other, in recombinant cell lines and primary leukocytes (Sohy et al., 2007; Sohy et al., 2009).
- TAK-779 the CCR2 and CCR5 antagonist, prevented calcium mobilization and chemotaxis initiated by the CXCR4 agonist CXCL12 in cells co-expressing CCR2 and CXCR4 or CCR5 and CXCR4 (Sohy et al., 2007; Sohy et al., 2009).
- Armando et al. showed that CXCR4 and CCR2 can form homo- and hetero-oligomers, and co-activation of CCR2 and CXCR4 with the human monocyte chemotactic protein 1 (MCP-1) and CXCL12 caused a synergistic increase in calcium mobilization (Armando et al., 2014).
- MCP-1 human monocyte chemotactic protein 1
- CXCR4 also interacts with ACKR3, also known as CXCR7, a chemokine family GPCR that binds the CXCL12 and CXCL11, but is unable to couple with G proteins upon agonist binding.
- Sierro et al. identified CXCR4-ACKR3 heteromers as functional heteromers that displayed enhanced CXCL12-induced calcium signaling and altered ERK1/2 signaling in HEK293 cells (Sierro et al., 2007). Lovoye et al., reported an opposite result showing that CXCR4-ACKR3 heteromers exhibited reduced G ⁇ i and calcium responses upon exposure to CXCL12 in CHO-K1 cells (Levoye et al., 2009). Decaillot et al.
- CXCR4 and ACKR3 constitutively recruited ⁇ -arrestin to CXCR4/ACKR3 heteromers and potentiated CXCL12-mediated ⁇ -arrestin-dependent downstream signaling pathways, including ERK1/2, p38 MAPK, and enhanced cell migration upon exposure to CXCL12 (Decaillot et al., 2011).
- CXCR4 also interacts with the chemerin chemokine-like receptor 1 (CMKLR1, also known as ChemR23) (de Poorter et al., 2013).
- CXCR4-CMKLR1 heteromers display negative agonist binding cooperativity similar to CXCR4-CCR2 and CXCR4-CCR5 heteromers reported by Sohy et al. (Sohy et al., 2007; Sohy et al., 2009), AMD3100 did not cross inhibit chemerin binding or inhibit calcium mobilization induced by CXCL12 (de Poorter et al., 2013).
- CXCR4 and the ⁇ -opioid receptor (DOR) are widely distributed in brain tissues and immune cells.
- Pello et al. reported that CXCR4 and DOR can form heteromers, and simultaneous stimulation with both agonists suppressed the activation of G ⁇ i signaling, and prevented cell migration toward CXCL12, although individual agonist elicit robust G ⁇ i signaling (Pello et al., 2008).
- Burbassi et al. also noticed increased CXCR4-DOR heteromers and reduced coupling of CXCR4 to G-proteins in brain tissue and cultured glia from ⁇ -opioid receptor (MOR)-deficient mice (Burbassi et al., 2010).
- CXCR4 function was rescued with a DOR antagonist, indicating that DOR is involved in the suppression of CXCR4 in glia by forming CXCR4-DOR heteromers (Burbassi et al., 2010).
- CXCR4 is also known to interact with ⁇ - and ⁇ -adrenergic receptors ( ⁇ -AR and ⁇ -AR).
- ⁇ -AR and ⁇ -AR ⁇ -adrenergic receptors
- LaRocca et al. reported that stimulation of CXCR4 with CXCL12 negatively regulates ⁇ -AR-induced cAMP accumulation and PKA-dependent phosphorylation of phospholamban in adult rat ventricular myocytes using non-selective ⁇ -AR agonist, isoproterenol (LaRocca et al., 2010).
- ADRB2 Nakai et al. studied the function of ADRB2 on lymphocytes. Stimulation of lymphocytes with ADRB2-selective agonists suppressed egress of lymphocytes from lymph nodes and produced lymphopenia in mice (Nakai et al., 2014). ADRB2 physically interacted with CCR7 and CXCR4, and activation of ADRB2 enhanced retention-promoting signals through CCR7-ADRB2 and CXCR4-ADRB2 heteromers, and subsequently reduced lymphocyte egress from lymph nodes.
- Tripathi et al. revealed the presence of CXCR4-ADRA1A ( ⁇ 1A-AR) and CXCR4-ADRA1B ( ⁇ 1B-AR) heteromers on the surface of vascular smooth muscle cells (VSMC) (Tripathi et al., 2015).
- a peptide derived from the second transmembrane helix of CXCR4 disrupted the interaction between ADRA1A/B and CXCR4, inhibited calcium mobilization and contraction of VSMC upon ⁇ 1-AR stimulation.
- Activation of CXCR4 with CXCL12 increased the potency of ⁇ 1-AR agonists on blood pressure response in rats, suggesting that CXCR4-ADRA1A/B heteromers could be a novel pharmacological target for blood pressure regulation.
- CXCR4 was reported to interact with CNR2 (Cannabinoid Receptor 2, aka CB2) (Coke et al., 2016; Scarlett et al., 2018). Simultaneous activation of CXCR4 and CB2 with both agonists resulted in reduction of ERK1/2 activation, calcium mobilization and cellular chemotaxis. These results show that cannabinoid system can negatively modulate CXCR4 function and tumor progression.

- CXCR4 plays important roles in tumor formation and progression, but the development of CXCR4 antagonists as anticancer drugs has not been successful possibly due to side effects and lack of efficacy within acceptable dose ranges. Recently, various CXCR4-GPCR heteromers with distinct physiological and pharmacological properties were reported, but their roles in cancer biology or possibilities for developing anti-cancer therapeutics targeting CXCR4-GPCR heteromers have not been clearly understood.
- GPCR heteromerization is known to alter GPCR maturation and cell surface delivery, ligand binding affinity, signaling intensity and pathways, as well as receptor desensitization and recycling (Terrillon and Bouvier 2004; Ferre et al., 2010; Rozenfeld and Devi 2010; Gomes et al., 2016; Farran 2017).
- GPCR heteromers display distinct functional and pharmacological properties, and GPCR heteromerization can vary depending on cell types, tissues, and diseases or pathological conditions (Terrillon and Bouvier 2004; Ferre et al., 2010;Rozenfeld and Devi 2010; Gomes et al., 2016; Farran 2017).
- GPCR heteromerization is regarded as a general phenomenon, and deciphering GPCR heteromerization opens new avenues for understanding receptor function, physiology, roles in diseases and pathological conditions. Accordingly, identification of GPCR heteromers and their functional properties offers new opportunity for developing new pharmaceuticals or finding new use of old drugs with fewer side effects, higher efficacy, and increased tissue selectivity (Ferre et al., 2010; Rozenfeld and Devi 2010; Farran 2017).
- GPCR heteromer The identification of bona fide GPCR heteromer requires intensive and critical evaluation.

- Heteromers should exhibit appropriate co-localization and interaction to enable allosterism using co-immunoprecipitation, in situ hybridization, or proximity-based techniques including proximity ligation assays in cells/tissues that express both receptors and not in cells/tissues that lack one of the receptors; (2) Heteromers should exhibit distinct properties such as changes in signaling, ligand binding, and/or trafficking, only in cells/tissues expressing both receptors but not in cells/tissues that lack one of the receptors; and (3) Heteromer-selective reagents should alter heteromer-specific properties.
- Heteromer-selective reagents include heteromer-selective antibodies, membrane-permeable peptides, and bivalent/bifunctional ligands (Gomes et al., 2016; Pin et al., 2007). Although many GPCR heteromers have been identified in vitro using recombinant receptors expressed in heterologous cells, only a few have demonstrated novel properties, and very few have shown evidence for GPCR heteromerization in native tissue due to technical problems (Gomes et al., 2016). NC-IUPHAR announced that one should provide evidence that satisfies at least two of the above three criteria for approval of new GPCR heteromers (Pin et al., 2007).

- ADCYAP1R1 is a membrane-associated protein and shares significant homology with members of the G-protein coupled class B glucagon/secretin receptor family. This receptor mediates diverse biological actions of adenylate cyclase activating polypeptide 1 and is positively coupled to adenylate cyclase (Vaudry et al., 2000). This is a receptor for PACAP-27 and PACAP-38.
- ADCYAP1R1 may regulate the release of adrenocorticotropin, luteinizing hormone, growth hormone, prolactin, epinephrine, and catecholamine. ADCYAP1R1 may play a role in spermatogenesis and sperm motility. ADCYAP1R1 causes smooth muscle relaxation and secretion in the gastrointestinal tract (Ogi et al., 1993).

It is also expressed in the trigeminal, otic and superior cervical ganglia (prejunctional) and cerebral arteries (postjunctional) (Knutsson and Edvinsson, 2002). Diseases associated with ADCYAP1R1 include post-traumatic stress disorder (Lowe et al., 2015) and anxiety disorder. Among its related pathways are G alpha(s) signalling events and RET signaling (Cooper et al., 2013).
- Adenosine A2B receptor also known as ADORA2B
- ADORA2B is a G-protein coupled adenosine receptor, and also denotes the human adenosine A2b receptor gene which encodes it.
- Adenosine functions as a signaling molecule through the activation of four distinct adenosine receptors - ADORA1, ADORA2A, ADORA2B, and ADORA3, also called as A1, A2A, A2B, and A3, respectively.
- This integral membrane protein stimulates adenylate cyclase activity in the presence of adenosine. This protein also interacts with netrin-1, which is involved in axon elongation.
- ADORA2A and ADORA2B receptors are important in cancer immunology.
- the tumor microenvironment is hypoxic, which promotes the expression of CD39 and CD73 by immune cells.
- CD39 and CD73 are ectonucleotidases that convert ATP to adenosine, elevating concentrations of adenosine locally.
- Adenosine is a crucial mediator of altered immune function in cancer as it binds ADORA2A and ADORA2B receptors on lymphocytes silencing the antitumor immune response (Chen et al., 2013).
- ADORA2B has a role in regulating CXCR4 expression in vivo and in protecting against vascular lesion formation (Yang et al., 2008) and promotes progression of human oral cancer (Kasama et al., 2015). Identification of a pharmacologically tractable Fra-1/ADORA2B axis promoting breast cancer metastasis (Desmet et al., 2013). ADORA2B receptors display high expression levels in the cecum, colon and bladder, with lower levels in the lung, blood vessels and eye (Fagerberg et al., 2014).
- ADORA3 The adenosine A3 receptor, also known as ADORA3, is an adenosine receptor, but also denotes the human gene encoding it.
- ADORA3 receptors are G-protein coupled receptors that couple to Gi/Gq and are involved in a variety of intracellular signaling pathways and physiological functions. It mediates a sustained cardioprotective function during cardiac ischemia, it is involved in the inhibition of neutrophil degranulation in neutrophil-mediated tissue injury, it has been implicated in both neuroprotective and neurodegenerative effects, and it may also mediate both cell proliferation and cell death (Gao et al., 2008; Miwatashi et al., 2008).
- Cordycepin induces apoptosis in human bladder cancer cells via activation of ADORA3 receptors (Cao et al., 2017). Jafari et al. showed that ADORA3 receptor agonist inhibited survival of breast cancer stem cells via GLI-1 and ERK1/2 pathway (Jafari et al., 2017). ADORA3 is broadly expressed in adrenal (RPKM 4.4), small intestine (RPKM 2.9) and 20 other tissues containing brain, bladder, lymph node and colon (Fagerberg et al., 2014).
- ADRB2 The beta-2 adrenergic receptor ( ⁇ 2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that interacts with epinephrine, a hormone and neurotransmitter (ligand synonym, adrenaline) whose signaling, via a downstream L-type calcium channel interaction, mediates physiologic responses such as smooth muscle relaxation and bronchodilation (Gregorio et al., 2017).
- ADRB2 functions in muscular system such as smooth muscle relaxation, motor nerve terminals, glycogenolysis and in circulatory system such as heart muscle contraction, cardiac output increase.
- beta-2 stimulation by salbutamol increases intraocular pressure via net.
- the ADRB2 induces glycogenolysis and gluconeogenesis in liver and insulin secretion from pancreas (Fitzpatrick, 2004).
- ADRB2 signaling in the cardiac myocyte is modulated by interactions with CXCR4 (LaRocca et al., 2010). Norepinephrine attenuates CXCR4 expression and the corresponding invasion of MDA-MB-231 breast cancer cells via ADRB2 (Wang et al., 2015a). ADRB2 is expressed in several cancers such as pancreatic, prostate (Braadland et al., 2014; Xu et al., 2017), renal and breast cancer (Choy et al., 2016).
- C5AR1 The C5a receptor also known as complement component 5a receptor 1 (C5AR1) or CD88 (Cluster of Differentiation 88) is a G protein-coupled receptor for C5a. It functions as a complement receptor. C5AR1 modulates inflammatory responses, obesity, development and cancers. (Gerard and Gerard, 1994).
- the C5AR1 is expressed on granulocytes, monocytes, dendritic cells, hepatoma-derived cell line HepG2, astrocytes, microglia (Klos et al., 2013). C5AR1 is related in several diseases such as inflammatory bowel disease, rheumatoid arthritis, psoriasis, experimental allergic encephalomyelitis, multiple sclerosis, meningitis, and brain trauma (Lee et al., 2008).
- CT The calcitonin receptor
- the calcitonin receptor is a G protein-coupled receptor that binds the peptide hormone calcitonin and is involved in maintenance of calcium homeostasis, particularly with respect to bone formation and metabolism (Dacquin et al., 2004; Davey et al., 2008).
- CT works by activating the G-proteins Gs and Gq often found on osteoclasts, on cells in the kidney, and on cells in a number of regions of the brain. It may also affect the ovaries in women and the testes in men.
- the activity of this receptor is mediated by G proteins which activate adenylyl cyclase.
- the calcitonin receptor is thought to couple to the heterotrimeric guanosine triphosphate-binding protein that is sensitive to cholera toxin.
- the physiological effects of CT such as inhibition of osteoclast mediated bone resorption or increased Ca2+ excretion by the kidney are mediated by high affinity CTs (Albrandt et al., 1995).
- the muscarinic cholinergic receptors belong to a larger family of G protein-coupled receptors. The functional diversity of these receptors is defined by the binding of acetylcholine and includes cellular responses such as adenylate cyclase inhibition, phosphoinositide degeneration, and potassium channel mediation. Muscarinic receptors influence many effects of acetylcholine in the central and peripheral nervous system (Rang, 2003).
- the muscarinic cholinergic receptor 1 is involved in mediation of vagally-induced bronchoconstriction and in the acid secretion of the gastrointestinal tract. It is predominantly found bound to G proteins of class Gq that use upregulation of phospholipase C and, therefore, inositol trisphosphate and intracellular calcium as a signaling pathway (Qin et al., 2011).
- CHRM1 - CHRM5 Muscarinic receptors are widely distributed throughout the body and control distinct functions according to location and subtype (CHRM1 - CHRM5). They are predominantly expressed in the parasympathetic nervous system where they exert both inhibitory and excitatory effects. This receptor is found mediating slow excitatory postsynaptic potential at the ganglion in the postganglionic nerve, is common in exocrine glands and in the CNS (Johnson, 2002). Diseases associated with CHRM1 include asthma and heart block, congenital and Pelizaeus-Merzbacher disease. Activators of CHRM1 muscarinic acetylcholine receptors (mAChRs) may provide novel treatments for schizophrenia and Alzheimer's disease (Marlo et al., 2009).
- mAChRs muscarinic acetylcholine receptors
- EDNRB -- Endothelin receptor type B (ETB) receptor was cloned shortly after the ETA receptor (EDBRA).
- EDNRA Endothelin receptor type B
- the EDNRA belongs to class A of G protein-coupled heptahelical receptors with an external amino terminus and internal carboxy terminus and binding sites intrinsic to the heptahelical portions of the receptor.
- ET-1 has a high affinity for the EDNRB.
- the pharmacology of the EDNRB receptor is somewhat richer than that of the EDNRA in that multiple agonists of the EDNRB are recognized, including sarafotoxin 6c (S6c) and IRL1620.
- Selective antagonists of the EDNRB include BQ788, A192621, RES7011, and IRL2500.
- the EDNRB has been localized to cardiovascular tissues, the pulmonary system, neurons, bone, pancreas, and kidney (Watts, 2010).
- EDNRB is a G protein-coupled receptor which activates a phosphatidylinositol-calcium second messenger system. Its ligand, endothelin, consists of a family of three potent vasoactive peptides: ET1, ET2, and ET3. In melanocytic cells the EDNRB gene is regulated by the microphthalmia-associated transcription factor. Mutations in either gene are links to Waardenburg syndrome (Sato-Jin et al., 2008). The multigenic disorder, Hirschsprung disease type 2, is due to mutation in EDNRB gene (Tanaka et al., 1998). Diseases associated with EDNRB include Waardenburg syndrome, Type 4A and Abcd syndrome. Among its related pathways are calcium signaling pathway and prostaglandin synthesis and regulation of Waardenburg Syndrome (Sato-Jin et al., 2008).
- HRH1 The H1 receptor is a histamine receptor belonging to the family of rhodopsin-like G-protein-coupled receptors. This receptor is activated by the biogenic amine histamine.
- the HRH1 is linked to an intracellular G-protein (Gq) that activates phospholipase C and the inositol triphosphate (IP3) signaling pathway.
- Gq G-protein
- IP3 inositol triphosphate
- Antihistamines which act on this receptor, are used as anti-allergy drugs.
- the crystal structure of the receptor has been determined and used to discover new HRH1 ligands in structure-based virtual screening studies (de Graaf et al., 2011).
- a subunit of the G-protein subsequently dissociates and affects intracellular messaging including downstream signaling accomplished through various intermediaries such as cyclic AMP, cyclic GMP, calcium, and nuclear factor kappa B. It functions in immune-cell chemotaxis, pro-inflammatory cytokine production, expression of cell adhesion molecules, and other allergic and inflammatory conditions (Canonica and Blaiss, 2011).
- the HRH1 mediates the contraction of smooth muscles, increase in capillary permeability due to contraction of terminal venules, and catecholamine release from adrenal medulla, as well as mediating neurotransmission in the central nervous system. It is also known to contribute to the pathophysiology of allergic diseases such as atopic dermatitis, asthma, anaphylaxis and allergic rhinitis (Xie and He, 2005). It is expressed in smooth muscles, on vascular endothelial cells, in the heart, and in the central nervous system (de Graaf et al., 2011).
- MLNR -- Motilin receptor is a G protein-coupled receptor that binds motilin. Motilin in turn is an intestinal peptide that stimulates contraction of gut smooth muscle. Also, the MLNR mediates progastrokinetic effects. MLNR is an important therapeutic target for the treatment of hypomotility disorders (Depoortere, 2001).
- NTSR1 Neurotensin receptor 1 belongs to the large superfamily of G-protein coupled receptors. Neurotensin is a 13-amino acid peptide originally isolated from hypothalamic and later from intestines of bovine. In the brain, neurotensin is exclusively found in nerve cells, fibers, and terminals, whereas the majority of peripheral neurotensin is found in the endocrine N-cells located in the intestinal. Central or peripheral injections of neurotensin produce completely different pharmacological effects indicating that the peptide does not cross the blood-brain barrier. NTSR1 mediates the multiple functions of neurotensin, such as hypotension, hyperglycemia, hypothermia, antinociception, and regulation of intestinal motility and secretion (Vincent, 1995).
- Signaling is effected via G proteins that activate a phosphatidylinositol-calcium second messenger system. Signaling leads to the activation of downstream MAP kinases and protects cells against apoptosis (Heakal et al., 2011). Swift et al. showed altered expression of neurotensin receptors is associated with the differentiation state of prostate cancer (Swift et al., 2010).
- PTGER2 -- Prostaglandin E2 receptor 2 also known as EP2 is a prostaglandin receptor for prostaglandin E2 (PGE2) encoded by the human gene PTGER2.
- PGE2 prostaglandin receptor for prostaglandin E2
- PTGER2 is classified as a relaxant type of prostanoid receptor based on its ability, upon activation, to relax certain types of smooth muscle. When initially bound to PGE2 or any other of its agonists, it mobilizes G proteins containing the G ⁇ s-G ⁇ complex. The G ⁇ s- G ⁇ complexes dissociate into their G ⁇ s and G ⁇ subunits which in turn regulate cell signaling pathways.
- G ⁇ s stimulates adenyl cyclase to raise cellular levels of cAMP thereby activating PKA;
- PKA activates various types of signaling molecules such as the transcription factor CREB which lead to different types of functional responses depending on cell type (Markovic et al., 2017; Woodward et al., 2011).
- PTGER2 also activates the GSK-3 pathway which regulates cell migratory responses and innate immune responses including pro-inflammatory cytokine and interleukin production and Beta-catenin pathway which regulates not only cell-cell adhesion but also activates the Wnt signaling pathway which, in turn, stimulates the transcription of genes responsible for regulating cell migration and proliferation (Woodward et al., 2011).
- the PTGER2 receptor can act as a tumor promoter.
- PTGER2 gene knockout mice have less lung, breast, skin, and colon cancers following exposure to carcinogens. Knockout of this gene in mice with the adenomatous polyposis coli mutation also causes a decrease in the size and number of pre-cancerous intestinal polyps that the animals develop. These effects are commonly ascribed to the loss of PTGER2-mediated: vascular endothelial growth factor production and thereby of tumor vascularization; regulation of endothelial cell motility and survival; interference with transforming growth factor- ⁇ 's anti-cell proliferation activity; and, more recently, regulation of host anti-tumor immune responses (O'Callaghan and Houston, 2015).
- PTGER2 is widely distributed in humans. Its protein is expressed in human small intestine, lung, media of arteries and arterioles of the kidney, thymus, uterus, brain cerebral cortex, brain striatum, brain hippocampus, corneal epithelium, corneal choriocapillaries, Myometriuml cells, eosinophiles, sclera of the eye, articular cartilage, the corpus cavernosum of the penis, and airway smooth muscle cells; its mRNA is expressed in gingival fibroblasts, monocyte-derived dendritic cells, aorta, corpus cavernosum of the penis, articular cartilage, airway smooth muscle, and airway epithelial cells. In rats, the receptor protein and/or mRNA has been found in lung, spleen, intestine, skin, kidney, liver, long bones, and rather extensively throughout the brain and other parts of the central nervous system (Yagami et al., 2016).
- PTGER2 may be a target for treating and/or preventing particular human disorders involving: allergic diseases such as asthma (particular aspirin and nonsteroidal inflammatory drug-induced asthma syndromes) and rhinitis (Machado-Carvalho et al., 2014); glaucoma (Doucette and Walter, 2017); various diseases of the nervous system (Yagami et al., 2016); fractures, osteoporosis, and other bone abnormalities (Li et al., 2007); pulmonary fibrosis; certain forms of malignant disease such as colon cancer including those that arise from Adenomatous polyposis coli mutations (O'Callaghan and Houston, 2015); and salt-sensitive forms of hypertension (Yang and Du, 2012); This receptor has also been suggested to be a target for contraception (Sugimoto et al., 2015).

- CCR5 -- C-C chemokine receptor type 5 also known as CCR5 or CD195, is a protein on the surface of white blood cells that is involved in the immune system as it acts as a receptor for chemokines. This is the process by which T cells are attracted to specific tissue and organ targets.
- Certain populations have inherited the Delta 32 mutation resulting in the genetic deletion of a portion of the CCR5 gene. Homozygous carriers of this mutation are resistant to M-tropic strains of HIV-1 infection (Hutter et al., 2009).
- CCR5's cognate ligands include CCL3, CCL4 (also known as MIP 1 ⁇ and 1 ⁇ , respectively), and CCL3L1.
- CCR5 furthermore interacts with CCL5 (Struyf et al.
- CCR5 plays a role in inflammatory responses to infection, though its exact role in normal immune function is unclear. Regions of this protein are also crucial for chemokine ligand binding, functional response of the receptor, and HIV co-receptor activity (Barmania and Pepper, 2013). CCR5 is predominantly expressed on T cells, macrophages, dendritic cells, eosinophils, microglia and a subpopulation of ether breast or prostate cancer cells (Sicoli et al., 2014; Velasco-Velazquez et al., 2012).
- GALR1 -- Galanin receptor 1 (GAL1) is a G-protein coupled receptor encoded by the GALR1 gene.
- the ubiquitous neuropeptide galanin controls numerous functions such as endocrine secretions, intestinal motility, and behavioral activities. These regulatory effects of galanin are mediated through the interaction with specific membrane receptors and involve the pertussis toxin-sensitive guanine nucleotide binding proteins Gi/Go as transducing elements (Habert-Ortoli et al., 1994).

- Somatostatin receptor type 2 is a protein that in humans is encoded by the SSTR2 gene. Somatostatin acts at many sites to inhibit the release of many hormones and other secretory proteins. The biologic effects of somatostatin are probably mediated by a family of G protein-coupled receptors that are expressed in a tissue-specific manner. SSTR2 has been shown to interact with shank2 (Zitzer et al., 1999).
- SSTR2 encodes somatostatin receptor that can inhibit the cell proliferation of solid tumors.
- SSTR2 promoter hypermethylation is associated with the risk and progression of laryngeal squamous cell carcinoma in males (Shen et al., 2016). Most pituitary adenomas express SSTR2, but other somatostatin receptors are also found (Miller et al., 1995).

- CXCR4-GPCRx heteromers To identify novel CXCR4-GPCRx heteromers, we made recombinant adenoviruses encoding 143 GPCRs fused with N-terminal fragments of yellow fluorescent protein Venus (VN) and 147 GPCRs fused with C-terminal fragment of Venus (VC) as described in Song et al. (Song et al., 2014; SNU patent; Song, thesis). CXCR4-GPCR heteromers were identified using bimolecular fluorescence complementation (BiFC) assay (FIG. 1), in which two complementary VN and VC fragments of Venus reconstitute a fluorescent signal only when both fragments are close enough through interaction between two different proteins to which they are fused (Hu et al., 2002).
- BiFC bimolecular fluorescence complementation
- U-2 OS cells were plated in 96-well plates, were co-transduced with 30 MOI each of adenoviruses encoding CXCR4-VN and GPCRx-VC or CXCR4-VC and GPCRx-VN, and were allowed to express GPCRs for 2 days.
- BiFC and nuclear images were obtained from three fields per well using IN Cell Analyzer 1000. Images of about 200 cells from each well were analyzed with Multi-target analysis software in IN Cell Developer ToolBox (GE Healthcare, Waukesha, WI). Cell boundary was marked based on Hoechst signal, and fluorescence intensity per cell was measured. Cells with fluorescence intensities higher than background level were considered as BiFC positive cells. Dead cells that showed extremely high intensities were excluded from the cell count. Positive cells were determined, and positive cell count ratio ("BiFC score”) was calculated as (positive cells/total cells) x 100 (see Table 4 below).
- APLNR-VC (FIG. 2h), C5AR1-VC (FIG. 2i), CALCR-VC (FIG. 2j), CCR5-VC (FIG. 2k), CHRM1-VC (FIG. 2l), GALR1-VC (FIG. 2m), EDNRB-VC (FIG. 2n), HRH1-VC (FIG. 2o), MLNR-VC (FIG. 2p), NTSR1-VC (FIG. 2q), PTGER2-VC (FIG. 2r), SSTR2-VC (FIG. 2t), and TACR3-VC (FIG. 2u).
- Protein-protein interaction can be affected by fusion tags such as fluorescence protein fragments in BiFC or renilla luciferase in BRET through interfering with the expression, folding, or localization of the partner protein.
- Partner protein can also impair the expression or folding of the fusion tags, and affect proximity-based assay result.
- the absence of signal between two proteins in specific combination does not necessarily imply that the proteins do not interact, but simply that the attached donor and acceptor molecules are in particular conformation that does not allow interaction to occur (Eidne et al., 2002; Kerppola, 2006).
- CXCR4 and GPCRx that gave BiFC signal in either CXCR4-VN and GPCRx-VC or CXCR4-VC and GPCRx-VN combination were considered as interacting proteins.
- CXCR4-GPCRx pairs that gave BiFC score equal or higher than 10 were selected as candidates for CXCR-GPCRx heteromer as shown in Table 4.
- GPCRs ADCYAP1R1, ADORA3, ADRB2, APLNR, C5AR1, CALCR, CCR5, CHRM1, GALR1, EDNRB, HRH1, MLNR, NTSR1, PTGER2, SSTR2, and TACR3, were identified as CXCR4-interacting GPCRs in CXCR4-VN and GPCRx-VC combination and two GPCRs, ADORA2B and PTGER3, gave BiFC score higher than 10 in CXCR4-VC and GPCRx-VN combination as shown in Table 4.
- ADRB2 and CCR5 have been reported to form heteromers with CXCR4 (LaRocca 2010, Nakai 2014, (Agrawal et al., 2004; LaRocca et al., 2010; Rodriguez-Frade et al., 2004; Sohy et al., 2007; Sohy et al., 2009; Martinez-Munoz et al., 2014)), and the remaining 16 GPCRs were found to be novel CXCR4-GPCRx heteromers that have not been reported to the best of our knowledge.
- ADRA1A and CXCR3 were also included in our BiFC assay. These GPCRs were excluded from further investigation since they gave BiFC signal of less than 10 with CXCR4: ADRA1A (CXCR4-VN-ADRA1A-VC: BiFC score 7.85) and CXCR3 (BiFC score 1.16).
- Cannabinoid Receptor 2 (CB2, sometimes referred to as CNR2) was identified as a CXCR4-interacting GPCR in our BiFC assay (CNR2-VN-CXCR4-VC configuration: BiFC score 4.25; CNR2-VC-CXCR4-VN configuration: BiFC score 38.1), and co-internalization assay as described in FIGS. 3a-3b and 4a-4q. But CNR2 was not selected as the final candiadate because it failed to exhibit an enhanced downstream signaling in the calcium mobilization assay (see Example 3 below).
- GPCR heteromers are known to exhibit, as a result of the heteromerization, altered trafficking properties such as maturation of the partner GPCR (GABA(B) receptor) (White, 1998), agonist-mediated internalization of the partner GPCR from the cell surface (DOR-GRPR, A2A-D2R) (Hillion et al., 2002; Liu et al., 2011; Torvinen et al., 2005), and changes in the localization of the partner GPCR from an intracellular compartment to the cell surface (DOR-CB1) (Rozenfeld et al., 2012).

- the selection of the concentration of these GPCRx agonists was initially set at the EC50 concentration (or alternatively, the Ki or Kd concentration) for the respective specific GPCRx, and if the resulting signal was too intense, then the concertation was lowered below the EC50, and if the resulting signal was too weak, then the concertation was increased to no more than 10,000x the EC50 concentration.
- CXCR4-GPCRx heteromers identified by BiFC assay, 16 heteromers containing the following GPCRx induced internalization of CXCR4 as revealed by increased intracellular GFP granules and reduced GFP signal in the plasma membrane in cells co-expressing CXCR4-GFP and GPCRx, confirming heteromer co-internalization: ADCYAP1R1, ADORA2B, ADORA3, ADRB2, APLNR, C5AR1, CCR5, CHRM1, GALR1, EDNRB, HRH1, MLNR, NTSR1, PTGER3, SSTR2, and TACR3 (FIG. 4b-q).

- co-treatment of CXCL12 and respective GPCRx agonist significantly increased calcium responses compared with the sum of calcium responses that were induced by individual agonists as shown in FIGS. 5c and 5d, and as shown in FIGS. 6a-6l.
- the cells co-expressing the CXCR4 and the GPCRx either ADCYAP1R1 (FIG. 6a), ADORA2B (FIG. 6b), ADORA3 (FIG. 6c), C5AR1 (FIG. 6d), CALCR (FIG. 6e), CHRM1 (FIG. 6f), EDNRB (FIG. 6g), HRH1 (FIG. 6h), MLNR (FIG.
- CXCL12-induced calcium response was significantly reduced, rather than enhanced, upon addition of CXCL12 alone or together with JWH-133, a selective CNR2 agonist, compared with the CXCL12-mediated calcium response observed in cells expressing CXCR4 alone (data not shown).
- those systems co-expressing CXCR4 and the GPCRx selected from the group consisting of ADCYAP1R1 (FIG. 6a), ADORA2B (FIG. 6b), ADORA3 (FIG. 6c), C5AR1 (FIG. 6d), CALCR (FIG. 6e), CHRM1 (FIG. 6f), EDNRB (FIG. 6g), HRH1 (FIG. 6h), MLNR (FIG. 6i), NTSR1 (FIG. 6j), and TACR3 (FIG.
- CXCR4-GPCRx heteromers would increase the sensitivity and dynamic range of these receptors at limiting ligand concentrations in vivo , and may be associated with poor prognosis.
- the enhanced calcium signaling by the CXCR4-GPCRx heteromers also indicates that the current diagnosis based on the level of CXCR4 expression alone needs to be changed to consider the expression levels of CXCR4 and GPCRx.
- GPCRs such as APLNR (FIG. 7a), CCR5 (FIG. 7b), GALR1 (FIG. 7c), PTGER3 (FIG. 7d), and SSTR2 (FIG. 7e) did not show enhanced calcium responses when cells expressing both receptors were co-treated with both agonists, although these GPCRs were shown to interact with CXCR4 in BiFC (Table 5) and CXCR4-GFP co-internalization assay.
- CXCR4-GPCRx heteromers that is not shared by other CXCR4-GPCRx heteromers such as CXCR4-APLNR, CXCR4-CCR5, CXCR4-GALR1, CXCR4-PTGER3, and CXCR4-SSTR2.
- CXCR4-GFP expressing U-2 OS cells were co-internalized by partner GPCRx specific agonist when CXCR4 and GPCRx were simultaneously transduced to cells (control: CXCR4-GFP (FIG. 4a)). If CXCR4 formed heterodimer with GPCRx and co-internalized by partner GPCRx, it can be blocked by GPCRx specific antagonist.
- U-2 OS cells stably expressing CXCR4-GFP were transduced with Adenoviruses encoding GPCRx (ADRB2, CHRM1, HRH1). After 2 days, images were obtained before and 20 minutes after stimulating cells with CXCR4-specific agonist, CXCL12 (SDF-1) (20 nM), and/ or GPCRx-specific antagonist (10 ⁇ M). Internalization of CXCR4-GFP was observed as GFP granules using IN Cell Analyzer 2500. Loss of GFP expression on the cell surface or appearance of GFP granules inside the cells were considered as CXCR4-GFP co-internalization.
- CXCR4 agonist, CXCL12 induced internalization of CXCR4-GFP with GPCRx
- GPCRx antagonists treated as follows, had no effect on the internalization of the heteromer (FIGS. 10a-c, second columns): Carvedilol, an ADRB2 antagonist (FIG. 10a); Oxybutynin and Umeclidinium, CHRM1 antagonists (FIG. 10b); Prometazine, Hydroxyzine, and Loratadine, HRH1 antagonists (FIG. 10c).

- ATPlite is an Adenosine Triphospate monitoring system based on firefly luciferase. This luminescence assay is the alternative to colorimetric, fluorometric and radioisotopic assays for the quantitative evaluation of proliferation and cytotoxicity of cultured mammalian cells.
- Cells were seeded in 384-well plate at 500 cells/well in 40 ⁇ l culture media. After overnight growth, the cells were cultured for 7 days in the presence of several dose of GPCRx antagonist or DMSO alone.
- Cell viability (%) (OD of antagonist treatment/OD of DMSO only treatment) x 100%.
- Example 6 Evaluation of CXCR4-GPCRx heteromer formation in patient derived cells (PDC) using Proximity ligation assay (PLA).
- Bazin et al. employed a time-resolved fluorescence resonance energy transfer (TR-FRET)-based approach that offers a much higher signal-to-noise ratio (Bazin et al., 2002).
- FRET is based on the transfer of energy between two fluorophores, a donor and an acceptor, when in close proximity. Molecular interactions between biomolecules can be assessed by coupling each partner with a fluorescent label and by detecting the level of energy transfer. Introducing a time delay of approximately 50 to 150 ⁇ seconds between the system excitation and fluorescence measurement allows the signal to be cleared of all non-specific short-lived emissions.
- Proximity ligation assay is a technology that extends the capabilities of traditional immunoassays to include direct detection of proteins, protein interactions and modifications with high specificity and sensitivity (Gullberg et al., 2004).
- Two primary antibodies raised in different species recognize the target antigen on the proteins of interest.
- Secondary antibodies directed against the constant regions of the different primary antibodies, called PLA probes bind to the primary antibodies.
- Each of the PLA probes has a unique short DNA strand attached to it, If the PLA probes are in close proximity (that is, if the two original proteins of interest are in close proximity, or part of a protein complex, as shown in the figures), the DNA strands can participate in rolling circle DNA synthesis when appropriate substrates and enzymes are added.
- the DNA synthesis reaction results in several-hundred fold amplification of the DNA circle.
- fluorescent-labeled complementary oligonucleotide probes are added, and they bind to the amplified DNA.
- the resulting high concentration of fluorescence is easily visible as a distinct bright spot when viewed with a fluorescence microscope (Gustafsdottir et al., 2005).
- CXCR4 overexpressing cell line U2OS-CXCR4
- ADRB2 expressing adenovirus Ad-ADRB2

- FIG. 12b The red signal spots were counted and calculated by normalization against negative control. The PLA signal increased proportionate to the expression level of ADRB2 in a dose dependent manner.
- FIG. 12c To investigate endogenous ADRB2 expression, qRT-PCR was performed with ADRB2 specific primers. As the results show, endogenous ADRB2 expression level of U2OS cell was quite high, indicating that the PLA signal is detected even in the section without virus infection (at 0 MOI for ADRB2).
- GBM Glioblastoma
- PDC Patient derived cell
- the patient derived cells were plated and fixed with 4 % PFA on sixteen-well tissue culture slides. Slides were blocked with blocking solution provided by Duolink and incubated with mouse anti-CXCR4 (1:200, Santa Cruz, Sc-53534), rabbit anti-ADRB2 (1:200, Thermo Scientific, PA5-33333), rabbit anti-CHRM1 (1:200, Lsbio, Ls-C313301) at 37 °C for 1 h in a humidifying chamber. Slides were then washed and incubated (1 h at 37 °C) with secondary anti-rabbit and anti-mouse antibodies conjugated with plus and minus Duolink II PLA probes.
- PLA ratio refers to the CXCR4 GPCRx heteromer, and the frequency of the heteromer formation varies depending on the patient.
- PLA ratio was calculated as: number of fluorescent spots in PDC sample / number of fluorescent spots in negative control.
- Negative control represents background fluorescence signal, indicated by the number of spots when only the secondary antibody conjugated with plus and minus Duolink II PLA probes is treated without primary antibody (mouse anti-CXCR4, rabbit anti-ADRB2, rabbit anti-CHRM1) treatment in PLA processing.
- Example 7 Evaluation of CXCR4-GPCRx heteromer formation in vivo using PDX model.

Slides were blocked with blocking solution provided by Duolink and incubated with rabbit anti-CXCR4 (1:200, Thermoscientific, PA3305), mouse anti-ADRB2 (1:200, Santacruz, Sc-271322), at 37 °C for 1 h in a humidifying chamber. The other process was same as described above (PLA with PDC).
- FIG. 15a nuclei were visualized with DAPI staining, and CXCR4-ADRB4 heteromers were stained with PLA as small dots.
- FIG. 15b PLA ratio is different according to the patient and based on this result, indicating that it is possible to perform personalized medicine by the companion diagnostics.

- MDA-MB-231 cells express about twice more HRH1 mRNA compared with CXCR4 mRNA when measured by RT-qPCR, the MDA-MB-231 cells were transduced with small amount of lentivirus encoding CXCR4 (1 MOI) and chemotactic migration of the cells toward CXCL12 and HRH1 was measured (FIGS. 19a and 19b). Histamine (50 nM) alone, sufficient to produce calcium signaling as shown in FIG. 27a (see below), did not induce cell migration. On the other hand, when treated together with CXCL12, histamine significantly enhanced the migration of MDA-MB-231 cells towards CXCL12.
- Example 11 Evaluation by Ca2+ mobilization assay of enhanced CXCR4 downstream signaling upon CXCR4-GPCRx heteromer formation and inhibition of the enhanced signaling.
- MDA-MB-231 human breast cancer cells were seeded at 20,000 cells per well in a black clear bottom 96-well plate (Corning Costar, #3340) in 100 ⁇ L of RPMI 1640 supplemented with 10% FBS. The next day, cells were co-transduced with 10 MOI of CXCR4 and 30 MOI of GPCRx.

- the U2OS-CXCR4 was infected with GPCRx expressing adenovirus, Ad-GPCRx at the dose of 0, 2.5, 10, 40 MOIs for 2 days.
- PLA was performed as described previously (Brueggemann et al., 2014; Tripathi et al., 2014).
- To perform PLA infected cells were fixed with 4% PFA on sixteen-well tissue culture slides.
- Slides were blocked with blocking solution provided by Duolink and incubated with mouse anti-CXCR4 (Santacruz, Sc-53534), rabbit anti-CHRM1 (LS Bio, LS-C313301), or rabbit anti-HRH1 (Thermoscientific, PA5-27817) at 37°C for 1 h in a humidifying chamber. Slides were then washed and incubated (1 h at 37°C) with secondary anti-rabbit and anti-mouse antibodies conjugated with plus and minus Duolink II PLA probes. Slides were washed again and then incubated with ligation-ligase solution (30 min at 37°C) followed by incubation with amplification-polymerase solution (2 h at 37°C).
- Example 13 Ca2+ Mobilization Inhibition of the Enhanced CXCR4 Downstream Signaling upon CXCR4-GPCRx heteromer Formation - Comparison of Single Inhibitor Treatment to Combination Inhibitor Treatment.
- MDA-MB-231 cells were transduced with adenoviruses encoding CXCR4 only, or CXCR4 and ADRB.
- the cells were cultured for 2 days and were treated CXCR4 inhibitor alone or co-treated with a CXCR4 inhibitor and an ADRB2 inhibitor (Carvedilol; 10 uM).
- the cells were then stained with Cal-6 for 2 hours and stimulated with CXCR4 agonsit (CXCL12; 20 nM) and ADRB2 agonist (Salmeterol; 1 ⁇ M).
- the IC50 value of Ca 2+ response was CXCR4 inhibitor dependent in the context of single treatment of MDA-MB-231 cells expressing CXCR4 alone, and in the single treatment context and the co-treatment context with an ADRB2 inhibitor of MDA-MB-231 cells expressing CXCR4-ADRB2 heteromer.
- the IC50 value of Ca 2+ response in the CXCR4-ADRB2 heteromer context decreased by 1400 times or more when treated in combination with an ADRB2 inhibitor (3 rd column), relative to single treatment with the CXCR4 inhibitor alone (4 th column).
- the IC50 value of Ca 2+ response in the CXCR4-ADRB2 heteromer context decreased about 540 fold (from 28.65 nM to 0.053 nM), about 1400 fold (from 1.12 nM to 0.0008 nM), or about 890 fold (from 17.78 nM to 0.02 nM), upon co-treatment of Carvedilol with AMD3100, Ulocuplumab, or TZ14011, relative to single treatement with AMD3100, Ulocuplumab, or TZ14011, respectively.
- These results suggest that co-treating with a CXCR4 inhibitor and ADRB2 inhibitor more effectively inhibits increased Ca 2+ response than single treatment with a CXCR4 inhibitor alone in CXCR4-ADRB2 heteromer expressing cells.
- Example 14 Effect of CXCR4 -ADRB2 heteromer on Tumor Growth.
- cell lines stably overexpressing CXCR4 alone or CXCR4-ADRB2 heteromer were prepared in A549 lung cancer cell, and the same amount of cells (1x10 7 cell / head) were injected subcutaneously in nude mice to compare tumor growth rates.
- the tumor size at 28 days after transplantation was 351.4 ⁇ 214.7 mm 3 for A549, 726.9 ⁇ 259.6 mm 3 for A549-CXCR4, and 1012.2 ⁇ 556.1 mm 3 for A549-CXCR4-ADRB2.
- mice transplanted with the A549-CXCR4 overexpressing CXCR4 was faster than that of mice bearing only parental A549, and the fastest tumor growth was observed in mice transplanted with cells overexpressing the CXCR4-ADRB2 heteromer.
- the mice bearing CXCR4-expressing cell show relatively fast tumor growth as compared to the mice bearing parental cell A549, and the tumor growth is the fastest in mice transplanted with cells overexpressing the CXCR4-ADRB2 heteromer.

- FIG. 23a An ADCYAP1R1-selective endogenous ligand, enhanced Ca 2+ signaling was also observed (FIG. 23a).
- the result demonstrates that enhanced signaling of CXCR4-ADCYAP1R1 heteromer upon co-stimulation with CXCL12 is not only limited to VIP, but also selective ADCYAP1R1 natural ligand. It further suggests this enhancement could happen in vivo in cells expressing CXCR4 and ADCYAP1R1 together by their natural ligands.
- Enhanced Ca 2+ signaling was observed in cells expressing CXCR4 and ADORA2B (FIG. 6b) or CXCR4 and ADORA3 together (FIG. 6c), but not in cells expressing individual GPCR alone, upon co-treatment with CXCL12 and BAY 60-6583 (ADORA2B-selective agonist), or CXCL12 and Cl-IB-MECA (ADORA3-selective agonist), respectively.

- enhanced Ca 2+ signaling was also observed (FIG. 23d).
- the result demonstrates that natural endogenous ligand, not only synthetic agonist, enhances signaling of CXCR4-CHRM1 heteromer upon co-stimulation with CXCL12. It further suggests that synergistic enhancement of downstream signaling could happen in vivo in cells expressing CXCR4 and CHRM1 together by their natural ligands.

- enhanced Ca 2+ signaling was also observed (FIG. 23g).
- the result demonstrates that natural endogenous ligand, not only synthetic agonist, enhances signaling of CXCR4-TACR3 heteromer upon co-stimulation with CXCL12. It further suggests that synergistic enhancement of downstream signaling could happen in vivo in cells expressing CXCR4 and EDNRB together by their natural ligands.
- Example 16 Evaluation by Ca2+ Mobilization Assay of Enhanced CXCR4 Downstream Signaling Upon Co-stimulation of CXCR4-GPCRx heteromer.
- MDA-MB-231 cells co-expressing CXCR4 and ADCYAP1R1 stimulate stimulation with selective endogenous ligands CXCL12 alone or PACAP38 alone, respectively, produced calcium signaling dose-dependently (FIGS. 24a-24b).
- MDA-MB-231 cells were transduced with adenoviruses encoding CXCR4 and ADCYAP1R1.
- PACAP38 selective endogenous ligand
- FIG. 24a addition of small amount of ADCYAP1R1 selective endogenous ligand (PACAP38; 1 nM) significantly enhanced calcium response in a broad range of CXCL12 concentrations compared with the sum values calculated by adding the responses obtained by PACAP38 alone and CXCL12 alone at indicated doses (FIG. 24a).
- FIGS. 25a-25b The enhancement of calcium response in a broad range of ligand concentrations in cells co-expressing CXCR4 and TACR3 is shown in FIGS. 25a-25b.
- MDA-MB-231 cells were transduced with adenoviruses encoding CXCR4 and TACR3. Stimulation of the cells with CXCL12 alone or Neurokinin B alone, respectively, produced calcium signaling dose-dependently (FIGS. 25a-25b). As shown in FIG.

- MDA-MB-231 cells stably expressing CXCR4 were transduced with lentiviruses encoding Cas9 and guide RNA targeting HRH1.
- the presence of functional HRH1 was detected by measuring calcium responses upon exposure to histamine. While MDA CXCR4+ cells showed dose-dependent increase in calcium signaling upon exposure to histamine, MDA CXCR4+, HRH1- cells did not show any calcium response even at 1 ⁇ M histamine (FIG. 26a). The result implies almost complete absence of functional HRH1 in MDA CXCR4+, HRH1- cells.
- FIGS. 18a-18b significant enhancement in calcium signaling was also observed in wildtype MDA-MB-231 cells in the presence of CXCL12 and histamine together although individual ligand alone only produced faint signals.
- CXCR4 gene was targeted using CRISPR/Cas9 system, and expression of CXCR4 was detected using immunoblotting. Expression of CXCR4 was significantly decreased in MDA-MB-231 cells treated with guide RNA targeting CXCR4 compared to the expression in cells treated with control non-targeting guide RNA (FIG. 26b).
