Figure 5. The miR-346 affects cell proliferation and cell cycle. A549 and SPC-A-1 cells were analyzed after transfection. (A-B) CCK8 assays of A549 and SPC-A-1 cells after transfected with NC, miR-346, si-XPC and ASO-346. (C) Shown are representative photomicrographs of colony formation assay after transfected with NC, miR-346, si-XPC and ASO-346 for fourteen days. (D-E) Cell-cycle analysis was performed forty eight hours following the treatment A549 and SPC-A-1 cells with NC, miR-346, si-XPC and ASO-346. The DNA content was quantified by flow cytometric analysis. Assays were performed in triplicate. *P < 0.001, Means ± SEM was shown. Statistical analysis was conducted using student t-test.
