Modulation of Src and STAT3 phosphorylation in breast cancer cells by VaM. (A) The protein expression of p-Src, Src, p-STAT3 (Y705), STAT3 (Y705), and SHP-1 was confirmed by immunoblotting. The data were quantified and compared to that of the untreated groups. (B) MCF-7 cells pre-treated with pervanadate were treated with VaM, and the protein expression levels of p-STAT3 and STAT3 were examined by immunoblotting. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 compared to the no treatment concentration group. ++++
p < 0.0001 compared to VaM (500 μg/mL) group. The results are presented in the bar chart as the mean ± SD of the three independent experiments. Yellow circles represent the results of three independent experiments.
