ETS-1 is crucial for cisplatin-resistant HNSCC cell proliferation. a. Cal27CP, SCC25CP, and UMSCC74B cells were transfected with non-target siRNA or siRNA against ETS-1 for 48 h and ETS-1 protein levels were detected by Western blot. b. Cells transfected with non-target siRNA or siRNA against ETS-1 for 24 h were split into 6-well plates, followed by growth for an additional 72 h, at which point cell numbers were counted. c. Cells transfected with non-target siRNA or siRNA against ETS-1 for 24 h were split into 12-well plates (100 cells/well) and colony formation was observed after 7 days
