Mammary gland fat pads excised from DMBA-administered SENCAR mice that received a control treatment (corn oil, CAS, or PIS) or an experimental treatment (2HF, RAS, Rab, or combination of 2HF+RAS+Rab) were analyzed for changes in the expression of RLIP, pAkt, maspin, PCNA, survivin, CDK1, Bax, and Bcl2. β-actin was used as a loading control. Numbers below the blots represent the fold change in the levels of protein expression, compared to expression in control tissues, as determined by densitometry. 2HF, 2'-hydroxyflavanone-treated; CAS, scrambled antisense-treated; RAS, RLIP antisense-treated; PIS, preimmune serum-treated; Rab, RLIP antibody-treated.
