From: Somatic loss of estrogen receptor beta and p53 synergize to induce breast tumorigenesis
Inactivation of ERβ induces basal breast tumor phenotypes. Representative tumor sections from K14Crep53 F/F and K14CreERβ F/F p53 F/F female mice were stained with antibodies against cytokeratin 8 (CK8), cytokeratin 14 (CK14) and p63. Distinct expression patterns of luminal and basal markers were observed between mammary tumors from the two groups of mice. Scale bars, 100 μm. ER estrogen receptor
