ABSTRACT
Deregulation of production or degradation of sphingosine 1-phosphate (S1P), a bioactive lipid, involves in tumor progression, metastasis and chemoresistance. Since the tumor progression effects of S1P and its mechanism in human pancreatic cancer is not fully understood, we investigated the role of S1P in Capan-1 and Panc-1 cells proliferation and migration. The effects of S1P on proliferation, invasion and migration were studied using MTT and transwell assay, respectively. The concentrations of MMP2 and MMP9 were detected by ELISA assay. Role of S1P on the expressions of tyrosine kinase and cell proliferation related proteins were assessed by western blot. Our results showed that cell proliferation and migration were mediated by low concentration of S1P treatment in both cell lines. In addition, we also investigated another survival mechanism of S1P in cell survival and tumor progression, Src signaling pathway. These results indicated that roles of S1P in tumor progression were S1P receptor-dependent through interaction with Src signaling pathway. In conclude, our data demonstrated the importance of this molecule as a target to design novel anticancer drugs in future through S1P receptors and Src signaling pathway.
