Regulation of Stat1 in the absence of Stat3 measured by Western blot, 20 μg protein/lane. Westerns show total Stat1 and phosphorylated Stat1 (P.Stat1) at day 10 of lactation (lac, L) and days 2, 3, and 6 of involution (inv, I). (Graph left) densitometry analysis of three independent mice, mean ± sem calculated as a percentage of the highest value for each blot; (graph right) values relative to keratin 18 calculated as a proportion of the mean (hence, no error bars are included). (f+) BLG–Cre/Stat3^flox/+ (solid bars); (f−) BLG–Cre/Stat3^flox/− (open bars).
