ABSTRACT
@#

Objective:

To investigate the effects of ezrin enhancer knockout on ezrin gene expression, cell proliferation and migration of human esophageal carcinoma Eca-109 cells. @*@#

Methods:

The CRISPR/Cas9 recombinant plasmids targeting upstream/downstream of human ezrin enhancer were co-transfected into human esophageal carcinoma Eca-109 cells, and the cell line Eca-C2 with ezrin enhancer knockout was screened by purinomycin. Then the expression levels of ezrin mRNAand protein in Eca-C2 cells were detected by Real-time quantitative PCR (qPCR) and Western blotting, respectively; The expression levels of MAPK-pathway-related proteins were detected by protein array technology; and the effects of ezrin enhancer knockout on the proliferation and migration of Eca-C2 cells were analyzed by WST-1 method and wound-healing assay, respectively. @*@#

Results:

The human esophageal carcinoma cell line Eca-C2 with stable ezrin enhancer knockout was established successfully. Compared with control cells, the mRNA and protein expressions of ezrin in Eca-C2 cells were significantly reduced (all P<0.05).Among the 17 detected MAPK pathway related proteins in Eca-C2 cells, 9 proteins (AKT, CREB, GSK3b, MKK6, mTOR, P38, P53, P70S6K and RSK1) were down-regulated, and the cell proliferation and migration were significantly inhibited (all P<0.05).@*@#

Conclusion:

ezrin enhancer knockout can significantly inhibit the cell proliferation and migration of human esophageal carcinoma Eca-109 cells.
