Cancer&Entry Information
Cancer Name | pancreatic cancer |

Methods | qPCR, Luciferase reporter assay, Cell proliferation assay, MTT assay etc. |
Sample | prostate cancer tissues, cell lines (Patu8988, SW1990, BxPC-3, AsPC-1, CFPAC-1 and Panc-1) |
Expression Pattern | up-regulated |
Function Description | lncRNA-XIST was specifically upregulated in PC tissues and cell lines, and high XIST expression in PC was related to poorer prognosis (larger tumor size, perineural invasion, lymph node micrometastases and shorter overall survival). XIST augmented PC cell proliferation. In the present study, XIST and miR-133a reciprocally inhibited each other in PC cells. Exogenous miR-133a expression significantly inhibited PC cell proliferation. Moreover, as exhibited by luciferase reporter gene assays, miR-133a bound to XIST and the 3'UTR of EGFR by direct targeting. In PC tissues, miR-133a expression was down-regulated and EGFR expression was up-regulated; miR-133a was inversely correlated with EGFR and XIST, respectively; XIST was positively correlated with EGFR. Taken together, these findings will shed light on the role and mechanism of XIST/miR-133a/EGFR in regulating PC cells proliferation. |
