Ablation of Rank in mammary epithelial cells markedly decreases tumor formation in Brca1/p53 mutant female mice. (A) Representative whole mount images (haematoxylin staining, magnification 52×) and paraffin sections (H&E staining, scale bar, 200 μm) of mammary glands from 4-month-old K5Cre;Brca1;p53 double- and K5Cre;Rank;Brca1;p53 triple-knockout littermate mice. (B) Representative images (H&E staining, scale bar, 100 μm) and (C) quantification of low-grade MINs, high-grade MINs and adenocarcinomas in mammary glands from 4-month-old K5Cre;Brca1;p53 and K5Cre;Rank;Brca1;p53 mutant littermates. Data are shown as average number of foci/section of 1 inguinal and 2 thoracic mammary glands per mouse +/− SEM. n ≥ 4 mice/group. *P < 0.05, ***P < 0.001 (2-way ANOVA). (D) Representative images of Ki67 and γH2AX immunostaining of mammary glands from 4-month-old K5Cre;Brca1;p53 double- and K5Cre;Rank;Brca1;p53 triple-knockout littermates. Scale bar, 100 μm.
