Figure 6From: The transcription factor ATF3 acts as an oncogene in mouse mammary tumorigenesis Deregulation of cytokeratin expression in BK5.ATF3 mammary tumors. Immunohistochemistry of representative mammary tumors arising in BK5.ATF3 mice (a,c,e) or uninvolved mammary ducts of tumor-bearing animals (b,d,f) was performed with primary antibodies to CK10 (a,b), mIRS.a2 (c,d) and mIRS.a3.1 (e,f), and stained with the chromogenic substrate. Scale bar = 100 μm. KC, keratinaceous core; S, stroma.Back to article page
