Analysis of mammary output: Litter weights and northern analysis of milk protein gene expression in α-catenin deficient mammary tissue. (A) Weight of pups born to mothers with α-catenin deficient mammary glands. Litters (n = 4) that survived during the lactation period were weighed on days 1, 5, 10, and 15 after birth. Data represents the mean ± SEM; *p < 0.05. (B) Litters (n = 4) that failed to survive were counted on days 1, 5, and 10. Data represents the mean ± SEM; *p < 0.1. Open bars denote litters born to α-cat fl/+;WC mothers and hatched bars denote litters born to α-cat fl/fl;WC mothers. (C) Northern analysis of β-casein, WAP, WDNM1, K18, and GAPDH mRNA at parturition of indicated genotypes, D MMTV-Cre D.
