Abstract This study examined if the anti-tumorigenesis effect of Exendin-4 in HT29 and HCT116 colorectal
cancer (CRC) involves modulation of SIRT1 and Akt/GSR3K/β-catenin/NF-κB axis. HT29 and HCT116 cells were
treated either with increasing levels of Exendin-4 (0.0-200 µM) or with Exendin-4 (at its IC50) in the presence or
absence of EX-527 (10 µM/a selective SIRT1 inhibitor) or Exendin-4 (9-39) amide (E (9-39) A) (1 µM/an Exendin-4
antagonist). In a dose-dependent manner, Exendin-4 inhibited cell survival, but enhanced levels of lactate
dehydrogenase (LDH) and single-stranded DNA (ssDNA) in both HT29 and HCT116. In both cell lines and at… More >
