Figure 2. Knockdown of NKILA promotes proliferation of ESCC cells. (A) The knockdown efficiency of short hairpin RNA against NKILA was examined by qPCR in Eca109 and Eca9706 cells. (B) CCK-8 assays of Eca109 and Eca9706 cells after knockdown of NKILA. (C) Colony formation assays of Eca109 and Eca9706 cells after knockdown of NKILA. Left panel was representative images and right panel was statistical quantification. Data in A, B and C represents the mean ± SD of three repeated experiments. *P < 0.05.
