Pancreatic ductal adenocarcinoma (PDA) is one of the most lethal malignancies worldwide. All-trans retinoic acid (ATRA) has been used as an antistromal agent in PDA, and its antitumor effect has also been reported in various kinds of cancer, including PDA. Inhibition of p21-activated kinases (PAKs) is associated with decreased tumor growth and increased gemcitabine sensitivity. The aim of this study was to evaluate the inhibitory effects of ATRA alone and in combination with gemcitabine on cell growth and migration of wild-type and gemcitabine-resistant PDA cells and the potential mechanism(s) involved. Human (MiaPaCa-2) and murine (TB33117) PDA cell lines were incubated in increasing concen..View full abstract
