Abstract : Pre-mRNA alternative splicing (AS) constitutes a critical and flexible layer of regulation relevant to all biological processes. Alternative splicing profiles often change when cells are submitted to stress or develop into a tumor. Our results indicate that stress may kill a cell by disrupting a critical collaboration between hnRNP and SR proteins that normally prevents the production of a pro-apoptotic splice variant. We also identified hundreds of events that differentiate cancer from normal tissues. Many of these differences are driven by a drop in the expression of the splicing regulator RBFOX2 in cancer tissues. In addition, our results suggest that the architecture of transcripts is specifically redesigned in the tumor microenvironment to affect cancer development.
