Apoptosis
Reports from University of Alabama add new data to research in apoptosis
November 13th, 2008
According to recent research from the United States, "Microcephalin (MCPH1) has a crucial role in the DNA damage response by promoting the expression of Checkpoint kinase 1 (CHK1) and Breast cancer susceptibility gene 1 (BRCA1); however, the mechanism of this regulation remains unclear. Here, we show that MCPH1 regulates CHK1 and BRCA1 through the interaction with E2F1 on the promoters of both genes." "MCPH1 also regulates other E2F target genes involved in DNA repair and apoptosis such as RAD51, DDB2, TOPBP1, p73 and caspases. MCPH1 interacts with E2F1 on the p73 promoter, and regulates p73 induction and E2F1-induced apoptosis as a result of DNA damage. MCPH1 forms...
