Figure 4. XPC proto-oncogene is a target of miR-346 at specific 3’-UTR sites. (A) The 3’-UTR of XPC harbors one miR-346 cognate site. (B) Relative luciferase activity of reporter plasmids carrying wild-type or mutant XPC 3’-UTR in A549 and SPC-A-1 cells co-transfected with negative control (NC) or miR-346 mimic. (C) Protein expression of XPC in A549 and SPC-A-1 cells after transfected with NC, miR-346, si-XPC and ASO-346. Assays were performed in triplicate. *P < 0.001, Means ± SEM was shown. Statistical analysis was conducted using student t-test.
