Carcinomas showed relatively high expression of several genes associated with mammary epithelial cell growth and proliferation (e.g., cyclin D1, PDGFalpha) and relatively low expression of differentiation marker genes (e.g., beta -casein, whey acidic protein, transferrin).
Allelic imbalance and altered expression of genes in chromosome 2q11-2q16 from rat mammary gland carcinomas induced by 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine.

By immunohistochemical analysis, cyclin D1, Cdk4, and phospho-Rb nuclear protein expression was 5.7-, 3.9-, and 2.3-fold higher, respectively, in carcinomas than in normal mammary gland, whereas the expression of cyclin D2, cyclin D3, and Cdk6 was similar.
By quantitative real-time PCR, the mRNA expression of Rasa, Pi3kr1, Ccnh, and Il6st in carcinomas was, respectively, 22-, 20-, three- and threefold higher in carcinomas than in control mammary gland tissues (P<0.05, Student's t-test).
