Abstract
We report that the activation level of AMP-dependent protein kinase AMPK is elevated in cancer cell lines as a hallmark of their transformed state. In OVCAR3 and A431 cells, c-Src signals through protein kinase Cα, phospholipase Cγ, and LKB1 to AMPK. AMPK controls internal ribosome entry site (IRES) dependent translation in these cells. We suggest that AMPK activation via PKC might be a general mechanism to regulate IRES-dependent translation in cancer cells.Entities:
