Abstract:
Objective To study the effects and molecular mechanism of MAWBP in the proliferation, invasion and migration of human colorectal cancer cell lines. Methods Colorectal cancer cell lines, caco-2 and HT-29, were divided into MAWBP over-expressed group and control group. MAWBP was stablely over-expressed in both cell lines by lentivirus, and the positive clones were screened by puromycin. The expression of MAWBP gene at mRNA and protein levels was evaluated by RT-PCR and western blot. Cell proliferation was detected by MTT. Cell migration and invasion were detected by transwell experiment. The EMT related protein levels of Snail, E-cadherin, and MAPK pathway protein of ERK, p38, p-ERK, p-p38 were determined by western blot analysis. Results Compared with the control group, the expression of MAWBP was significantly higher in HT-29-MAWBP and caco2-MAWBP group . The cell proliferation , invasion and migration ability significantly reduced in the HT-29-MAWBP group. The expression of Snail, p-ERK and p-p38 significantly decreased, while the E-cadherin increased in HT-29-MAWBP and caco2-MAWBP group. Conclusions Over- expression of MAWBP exerts an inhibitory effect on the proliferation, invasion and migration of colorectal caner cells via inhibit the MAPK pathway and regulate the EMT process.
