Effect of resveratrol on STAT3 signaling in goat mammary epithelial cells (GMECs). Western blot analysis of phosphorylated-STAT3 (pSTAT3) and STAT3 in GMECs treated with resveratrol at various concentrations for 3 days (A) or treated with 10 μM resveratrol each day (B). The graphs show the results of densitometry analysis; α-tubulin was the internal control. Control GMECs were treated with 0.1% dimethyl sulfoxide. The data are presented as the mean ± SEM (n = 8). Asterisks show significant differences (p < 0.05 versus control).
