Research Abstract

In response to oxidative stress, colon cancer cells(HCT116) increased levels of TRA2β1 mRNA without changing its mRNA stability. TRA2βpromoters and Chip assay demonstrated that an Ets1-binding site was crucial for basal transcription, while three heat shock elements mediated the oxidant-induced transactivation of TRA2β. Tra2βknockdown caused apoptosis of HCT116 cells. Tra2βwere preferentially expressed in proliferative compartment of normal human colonic glands and adenocarcinomas, where Ets1 and HSF1 were also highly expressed.
