Fig. 6: Effect of S100A9 and FABP5 on cell proliferation and apoptosis.

A The effect of S100A9 on A431 cell proliferation was determined by CCK-8. B The effect of S100A9 on A431 cell apoptosis was measured by staining with Annexin V/PI, followed by FACS analysis. C The effect of FABP5 on A431 cell proliferation was determined by CCK-8. D The effect of FABP5 on A431 cell apoptosis was measured by staining with Annexin V/PI, followed by FACS analysis. E The effect of S100A9 and FABP5 on SCL-1 cell proliferation. F The effect of S100A9 and FABP5 on SCL-1 cell apoptosis. Data were presented as mean ± SD. siNC represents the siRNA negative control, and siS100A9 and siFABP5 represent the specific S100A9 siRNA and FABP5 siRNA, respectively.
