Abstract: Objective To investigate the expression of Pin1 in human pancreatic carcinoma as well as adjacent tissues and to discuss the role of Pinl in oncogenesis of pancreatic carcinoma. Methods Specimen of pancreatic carcinoma tissues and adjacent tissues were collected from 20 cases. Pin1 mRNA and protein expression in pancreatic neoplasm and corresponding adjacent nontumorous tissues were detected by real-time quantitative reverse transcription-polymerase chain reaction (RQ-RT-PCR) and western blot. Results Pin1 was overexpressed at mRNA and protein level in pancreatic carcinoma tissues compared with that in their nontumorous counterparts ( 2.78 ± 1.02 vs 4.36 ± 1.27;5. 48 ± 1.69 vs 9.97 ± 1.86, P ＜ 0.05 ). Pin1 expression was not correlated to clinical stage and pathological grading of the carcinoma. Conclusion Pin1 overexpression may play a key role in pancreatic carcinoma.
