PDCD10 promotes the tumor-supporting functions of TGF-β in pancreatic cancer.

ABSTRACT: The progression of pancreatic ductal adenocarcinoma (PDAC) is significantly affected by transforming growth factor (TGF)-β but targeting TGF-β can also compromize physiological effects in patients. Our study examined the functions of the ubiquitously expressed protein, PDCD10, as a modulator of TGF-β signaling in PDAC. Using in silico analyses we found that in patient samples, PDCD10 is significantly higher expressed in PDAC tumor tissue compared with normal pancreas and it is highly correlated with reduced survival. We created stable KO's of PDCD10 in two PDAC lines, PaTu 8902 (SMAD4 +/+) and PaTu 8988t (SMAD4 -/-), and found that KO lines are more sensitive to 5-FU and Gemcitabine treatment than their wild-type counterparts. Performing viability and wound closure assays we further found
