ERK1/2 in the activation of p53 in HNSCC cells treated with CisPt and/or CRM. (A) The total and phospho-p53 protein expression (ng/mg total protein lysate) in FaDu, PE/CA-PJ49 cells treated with CisPt and/or CRM. a, CisPt vs. Control; b, CRM vs. Control; c, CisPt+CRM vs. Control. (B) Inhibitory effect of PD98059 on the total and phospho-p53 expression. The experiments were performed in triplicates. Results are expressed as mean values of three determinations ± standard deviation (SD). [PD98059 effect (%) = (protein expression+PD98059/protein expression-PD98059) ×100]. a, CisPt vs. Control; b, CRM vs. Control; c, CisPt +CRM vs. Control.
