Results of protein analyses for fatty acid synthase (Fas) and CCAAT/enhancer binding protein (C/EBP), beta at 130 days of age. Western blot for fatty acid synthase showed that Fas protein was significantly less (p = 0.02 by T-test, n = 3/group) and that C/EBP, β was not quite significantly higher (p = 0.06 by T-Test, n = 3/group) in mammary glands of CA/CO mice than in CO/CO mice at 130 days. Values shown are relative density and have been corrected for protein loading (GAPDH) and for cytokeratin (to correct for the epithelial compartment of the assayed sample).
