Protein expression and function investigation of USF1 in LUAD. (A) The USF1 protein expression in the studied tissues were determined by immunohistochemical assay; (B) The protein expression of USF1 in cells were determined by WB; (C,D) Transfection efficiency was proved by WB in H1299 and A549 cells; (E,F) Cells viability was detected by CCK-8 assay in H1299 and A549 cells; (G,H) cells proliferation potential was detected by the colony forming assay in H1299 and A549 cells. (NC group, cells were transfected with si-NC; si-USF1 group cells were transfected with si-USF1; *p < .05 means statistically significant difference when compared with NC group).
