Outline of Final Research Achievements

We revealed that FOSL1 and KMT2D, a histone H3K4 methyltransferase, regulated the expressionof EHF in colorectal cancer cells. Moreover, we found that FOSL1 and KMT2D were required for the proliferation of colon cancer cells. Furthermore, we show that EHF knockdown stabilizes p53 protein. In addition, EHF interacts with and stabilizes the MDM2, a ubiquitin ligase, by interfering with its ubiquitination, which in turn destabilizes p53 protein. Finally, we identified RAD18 as a novel ubiquitinase for MDM2.
