Figure 9. miR-346 directly targeting XPC and then activating ERK/Snail pathway, which leads to decrease of E-cadherin. (A-B) Expression of XPC, phospho-ERK1/2, ERK2, Snail, and E-cadherin were detected in A549 and spc-a-1 cells either transiently transfected with NC, miR-346, si-XPC, or ASO-346. The intensity of XPC, phospho-ERK1/2, ERK2, Snail, and E-cadherin bands were quantified using Image J. Assays were performed in triplicate. *P < 0.05. Means ± SEM was shown. Statistical analysis was conducted using ANOVA.
