This study examined the implication of EMT induced by TGF-β1 in pancreatic cancer invasion. TGF-β1 expression was determined in 29 cases of human pancreatic carcinoma (PC) by immunohistochemistry and the results were compared with those of pathological examination. Moreover, the effects of TGF-β1 on the phenotype and invasion of pancreatic cancer cell line Panc-1 were also investigated. TGF-β1 was detected in 12 cases (41.4 %) of PC. Significant correlation was found between the expression of TGF-β1 and lymph node involvement (P=0.047) and the depth of invasion (P=0.035). TGF-β1 obviously promoted EMT of Panc-1 cell lines and their invasion ability was substantially enhanced. TGF-β1 may promote the malignancy of pancreatic cancer by triggering EMT.
