Perhaps the best understood pathway is that in the worm C. elegans, where detailed genetic studies have shown that two Bcl-2 related proteins (pro-apoptotic EGL-1 and pro-survival CED-9) are essential for controlling developmentally programmed somatic cell deaths (Horvitz, 1999). These drugs display binding to pro-survival Bcl-2 proteins resulting in actuation of apoptosis of cancer cells. Apoptosis; Bcl-2; Bcl-2 inhibitors; Cancer. Thrombocytopenia a major dose-limiting toxicity, associated with ABT-263 had provoked the invention of a highly selective Bcl-2 inhibitor venetoclax.
