Abstract:
Apoptosis is an essential physiological process that plays a critical role in development and cellular homeoastasis. This process is tightly regulated through multiple independent signalling pathways. Defects in apoptosis may contribute both to tumorigenesis and drug resistance. Understanding the molecular events that contribute to apoptosis enable a more rational approach to anticancer strategy development. These strategies will allow not only the development of new molecules targeting recently elucidated apoptotic signalling pathways, but also a better use of already kown drugs through new associations in so far as these target distinct signalling pathways.

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
