Background technique

ERR α is in 1988 by clone identifications such as Giguere.As orphan nuclear receptor (Orphan nuclear Receptor), ERR α endogenic ligand is undiscovered always.ERR α wide expression in vivo, from cardiac muscle, alimentary canal, brain, bone Malignant tumours such as bone flesh, brown fat and breast cancer, oophoroma etc. can detect.ERR α has with estrogen receptor alpha (ER α) Higher homology: DNA binding domain (DNA binding domain, DBD) amino acid similarity 68%, ligand binding domain (Ligand binding domain, LBD) similitude 33%.Different from estrogen receptor ER α, ERR α cannot be with estrogen knot It closes, but can identify that sequence is with ER α competitive binding estrogen response element (Estrogen response elemnt, ERE) AGGTCAnnn TGACCT；And ERR α also can combine one kind I type Steroidgenesis factor to react in the form of monomer or dimer Element TnAAGGTCA, also referred to as estrogen-related receptor response element (ERR response element, ERRE), show ERR α and ER α have juxtaposition when identifying DNA.

Nearest research prompt, in addition to participating in ER signal path, ERR α is in cellular energy metabolism, mitochondrial oxidation and biology Synthesis etc. has an important physiological action, the development for the histoorgan that wields influence of function, the aging of cell, the generation of tumour and Development etc..

Oncobiology basic research show orphan nuclear receptor-estrogen-related receptor α (ERR α) can promote hormone according to Growth, the invasion of bad/non-dependent breast cancer promote vascular smooth muscle cell proliferation, the formation of endothelium micro-pipe and tumor vessel new It is raw, it is meant that the drug of targeting ERR α has both the effect of anti-breast cancer, provides new strategy for Molecular Targeted Therapy for Breast Cancer.

In recent years, research disclose the estrogen such as relevant to the estrogen breast cancer of ERR α, carcinoma of endometrium and cervical carcinoma according to Rely property tumour closely related, more some researches show that numerous non-estrogen dependent tumors such as prostate cancer, sdenocarcinoma of stomach and Colon and rectums The occurrence and development of cancer etc. and clinical prognosis are also related to the expression of ERR α.Clinical research confirmation, ERR α breast cancer, colon cancer, Significant up-regulation is expressed in the tumours such as oophoroma and prostate cancer, is the independent risk factor an of prognosis mala.By up-regulation/under It adjusts ERR alpha expression or uses ERR alpha inhibitor, can effectively inhibit the transcriptional activity of hypoxia genes, to reduce internal solid tumor Angiogenesis and growth.These are studies have shown that ERR α may be the potential therapy target of kinds of tumors.ERR α inverse agonist XCT790 inhibits the proliferation and angiogenesis of kinds of tumor cells.ERR α inverse agonist SR16388 effectively inhibits nude mice The growth of prostate cancer in lotus knurl model.These are studies have shown that target the regulator of ERR α possible as clinically effective Anti-tumor drug.

In conclusion estrogen-related receptor ERR α can be used as the novel therapeutic target spot of kinds of tumors, it is based on estrogen phase Close the small-molecule modulators that receptor ERR α developed, it is most likely that the novel drugs molecule as treatment related disease tumour.
