Definitions

  • Programmed cell-death or apoptosis is a regulated process that involves an orchestrated series of biochemical events leading to characteristic cell morphology and eventually cell death, and is necessary in an organism's development and during the life cycle. For example, the differentiation of digits in a developing embryo requires cells between the digits to initiate apoptosis so that they can separate. Deregulated apoptotic processes have been implicated in an extensive variety of diseases. Excessive apoptosis causes hypotrophy, such as in ischemic damage, whereas an insufficient amount results in uncontrolled cell proliferation, such as in cancer.
  • Bcl-2 is the prototype of a family of mammalian genes and the proteins they produce (Chao, D. T., Korsmeyer, S. J., Annu Rev Immunol 16, 1998, 395-419; Cory, S., Adams, J.M. Nat Rev Cancer 2(9), 2002, 647-656), which govern mitochondrial outer membrane permeabilisation, and which can be either anti-apoptotic (including Bcl-2 proper, Bcl-xL, and Bcl-w) or pro-apoptotic (Bax, BAD, Bak and Bok among others). More than 20 genes in the Bcl-2 family are known to date.
  • Bcl-2 derives its name from B-cell lymphoma 2, as it is the second member of a group of genes described to be translocated in follicular lymphomas from chromosome 14 to 18 (Pegoraro, L., et al, Proc Natl Acad Sci USA 81, 1984, 7166-7170).
  • the Bcl-2 family has a general structure that consists of a hydrophobic helix surrounded by amphipathic helices. Many members of the family have transmembrane domains. Bcl-2 and its closely related BcI-X(L) counterpart are one of several pro-survival proteins which can share up to four highly conserved domains known as BHl, BH2, BH3 and BH4. These domains form the basis of a well-defined groove where a heterodimeric protein-protein interaction can occur with pro-apoptotic BH3 proteins such as Bad, Bid and Bim Chao, D.
  • the BH domains are known to be crucial for function, as deletion of these domains affects apoptosis rates.
  • Bcl-2 proteins such as Bcl-2 and Bcl-xL, all four BH domains are conserved.
  • the site of action for the Bcl-2 family is mostly on the outer mitochondrial membrane.
  • pro-apoptotic factors e.g., cytochrome C
  • caspases which are key proteins in the apoptotic cascade.
  • Bcl-2 proteins either promote the release of these factors, or keep them sequestered in the mitochondria.
  • the exact mechanisms surrounding Bcl-2 regulated mitochondrial outer membrane permeabilization have yet to be elucidated, but it is believed that the multidomain, pro-apoptotic Bcl-2 proteins can activate it directly, a process that is inhibited by the binding of anti-apoptotic Bcl-2 proteins.
  • Bcl-2 family genes and their resulting proteins exert their pro- or anti-apoptotic effects An important one states that this is achieved by activation or inactivation of an inner mitochondrial permeability transition pore, which is involved in the regulation of matrix Ca2+, pH, and voltage. It is also thought that some Bcl-2 family proteins can induce (pro- apoptotic members) or inhibit (anti-apoptotic members) the release of cytochrome C in to the cytosol, which, once there, activates caspase-9 and caspase-3, leading to apoptosis (Zamzami, N. et al., Oncogene 16, 1998, 2265-2282.) Overexpression of Bcl-2 is known to block cytochrome C release. Bcl-2 's role in disease
  • Cancer is one of the world's leading causes of death and occurs when the homeostatic balance between cell growth and death is disturbed. Extensive evidence indicates a strong correlation between neoplastic progression and deregulation of apoptotic pathways.
  • Overexpression of Bcl-2 family proteins is associated with tumor progression, poor prognosis and resistance to chemotherapy (Stauffer, S. R., Curr Top Med Chem 7(10), 2007, 961-965), hence the development of therapies which inhibit Bcl-2 proteins may prove to be beneficial in cancer and other proliferative disorders.
  • the Bcl-2 gene has been implicated in a number of cancers, including melanoma, breast, prostate, and lung cancer, supporting its role for decreased apoptosis in the pathogenesis of cancer.
  • antagonism of the protein-protein interactions of Bcl-2 family proteins are considered extremely important points for drug intervention in cancer.
  • Abbott has recently described a novel inhibitor of Bcl-2 and Bcl-xL, known as ABT-737 (Oltersdorf, T., et al. Nature 435, 2005, 677-681).
  • ABT-737 is one of several BH3 mimetic small molecule inhibitors targeting Bcl-2 and Bcl-2-related proteins such as Bcl-xL and McI-I. It has been shown to cause complete regression in small-cell lung carcinoma tumor xenografts in mice and may prove to be clinically useful as a new anticancer agent capable of overcoming apoptosis resistance. It is currently at the preclinical stage.
