Objective To evaluate the regulation of the TRPV1 receptor on the expression of EGFR protein and the effects on related cell functions. Methods Human pancreatic cancer cells PANC-1 were cultured and treated by over-expression and siRNA. Cell proliferations were detected by CCK-8 experiment. RT-PCR test was used to detect the expression of oncogenes Akt2 and K-ras. Results EGFR protein was down-regulated by TRPV1 over-expression or by agonist activation in pancreatic cancer cells. EGFR protein was increased by the interference of TRPV1 expression. The proliferation rate of pancreatic cancer cells was decreased and Akt2, K-ras were significantly inhibited by TRPV1 over-expressing. Conclusion The expression of TRPV1 in pancreatic cancer cells regulated the EGFR protein content. The cell proliferation and oncogene expression were inhibited by TRPV1 over-expressing.
