Immunoblot for p-ERK1/2, ERK1/2, p-EGFR, p-JNK, p-p38, Cyclin D1 and p27. a Representative blots of protein expression at 5 min, 30 min, 4 h, 12 h or 24 h of sham- or CRET- exposure to 448 kHz at 50 μA/mm2. 100 μg protein/lane. β-actin was used as loading control. C: sham-exposed controls, T: CRET-treated. b Immunoblot densitometry for protein expression. The data, normalized over controls, are means ± SD values of the protein/β-actin ratios for the corresponding proteins, at 5 min, 30 min, 4 h, 12 h or 24 h of treatment in at least 5 experimental repeats. *: 0.05 > p ≥ 0.01; **: 0.01 > p ≥ 0.001; Student’s t-test
