Figure 3. Suppression of FAM83A inhibited NSCLC cell migration and invasion capacity in vitro. (A) FAM83A protein level was assessed in NSCLC cell lines using Western blot analysis. β-actin was used as a loading control. (B) The intensity of protein levels was quantified using Image Lab 5.2.1 software and normalized to β-actin. (C–G) H661 and H1299 cells were transduced with FAM83A lentivirus (LV-shFAM83A-1/2) and a scrambled shRNA lentivirus (LV-shRNA-NC). The suppression of FAM83A in H661 and H1299 cells was confirmed at both the protein (C–F) and RNA (G) levels. (H–I) H661-shRNA-NC, H661-shFAM83A-1, H1299-shRNA-NC, and H1299-shFAM83A-1 cells were subjected to a wound-healing assay. Images were taken at 0 h and 24 h. (J–K) Transwell assays assessed tumor cell migration and invasion capacity in FAM83A-knockdown H661 and H1299 cell lines. Scale bar, 200 μm. Error bars: mean ± SD (n=3). *p<0.05, **p<0.01, and ***p<0.001 were considered to indicate a statistically significant difference.
