MYC-regulated RNA Binding Protein Networks and Spliced Isoforms Driving Cancer
SUMMARY Alternative RNA splicing is a key step in gene expression regulation and contributes to transcriptional diversity by selecting which transcript isoforms are produced in a specific cell at a specific time point. Aberrantly spliced isoforms can impact every one of the hallmarks of cancer, including increased cell proliferation, migration, or resistance to apoptosis. Regulatory splicing factors (SFs) have recently emerged as a new class of oncoproteins and tumor suppressors. In particular, the tumorigenic capacity of the oncogenic transcription factor MYC, which is dysregulated in >50% of human tumors, has been shown to be dependent on the splicing machinery and on at least 3 SFs…
