The SWI/SNF genetic blockade: effects in cell differentiation, cancer and developmental diseases

摘要

Our rapidly growing knowledge about cancer genetics attests to the widespread occurrence of alterations at genes encoding different components of the SWI/SNF complex. This reveals an important new feature that sustains cancer development: the blockade of chromatin remodeling. Here, we provide an overview of our current knowledge on the gene alterations of chromatin-remodeling factors, and how they relate to cancer and human developmental diseases. We also consider the functional repercussions, particularly how the inactivation of the SWI/SNF complex impairs the appropriate cell response to nuclear receptor signaling, which, in turn, prevents cell differentiation and sustains cell growth independently of the environment.
