Master regulators of apoptosis

It is becoming progressively more understandable that cancer is a multifaceted disease and gets complicated with progression of stages. increasingly it is being realized that metastatic cancer resembles a darwinian evolutionary system,which suggests that instead of passenger mutations there are 'driver' mutations and misrepresentations which occur at epigenetic level thus determining clonal selection according to branching trajectories. extensive preclinical experimentation and functional genomics provide convincing evidence that tumour microenvironment is another major determinant that gradually develops through rate-limiting steps during multistage carcinogenesis. confluence of information suggests that cancer cells exist in a closer and symbiotic relationship with other components of the tumour and respond to environmental clues through intracellular signaling cascades. surprisingly,it is now well known that cancer cells escape from death via impairing trail mediated signaling and dysregulated protein network in cancer cells. in this review,we will focus exclusively on how cancer cells escape from cell death.
