To explore the eff ect of grape seed proanthocyanidins extract (GSPE) on the growth of pancreatic cancer cells and the underlying mechanisms.
METHODS:
The pancreatic cancer AsPC-1 cells were cultured in vitro. The effects of GSPE on cell proliferation, apoptosis and migration were analyzed by MTT, Annexin V-FITC/PI and Transwell migration assay, respectively. The expression of miR-27a and FOXO1 in AsPC-1 cells was determined by real-time RT-PCR and Western blot, respectively. The miR-27a inhibitors were applied to verify the role of miR-27a in mediation of GSPE effects.
RESULTS:
GSPE inhibited cell growth in a dose-dependent manner. This inhibitory effect was significant when the dosage of GSPE was more than 50 μg/mL (P
