Involution related STAT3 signaling decreases in WAP-Brk mice. A, Representative phospho-STAT3 IHC in involuting mammary glands from INV D1-INV D6 wild-type and Brk97 mice, 400 × magnification. B, Quantification of positive IHC staining, as a percentage of total mammary epithelium. Asterisks signify statistically significant differences between groups (P < 0.05).
