Knockdown of FAM83A inhibits the malignant phenotype of LUAD in NCIH1650 cells. (A) Expression plot FAM83A in multiple cancer cell lines. (B) Expression of FAM83A in some lung_NSC cells and the common LUAD cell line NCIH1650 was chosen for further research. (C) Transfection efficiency of siRNAs were confirmed using reverse transcirption-quantitative PCR and western blotting. (D) EdU (magnification, ×400) and (E) CCK-8 assays indicated that silencing FAM83A suppressed proliferation of NCIH1650 cells. (F) Transwell (×400) and (G) Matrigel (magnification, ×400) assays suggested that knockdown of FAM83A inhibited migration and invasion of NCIH1650 cells. ***P<0.001 vs. si-NC. lung_NSC, non-small cell lung cancer; CCK-8, Cell Counting Kit-8; si, small interfering; NC, negative control.
