Soy Protein Isolate Protects Against Ethanol-Mediated Tumor Progression in Diethylnitrosamine-Treated Male Mice.

ABSTRACT: In this study, diethylnitrosamine-treated male mice were assigned to three groups: (i) a 35% high fat ethanol liquid diet (EtOH) with casein as the protein source, (ii) the same EtOH liquid diet with soy protein isolate as the sole protein source (EtOH/SPI), (iii) and a chow group. EtOH feeding continued for 16 weeks. As expected, EtOH increased the incidence and multiplicity of basophilic lesions and adenomas compared with the chow group, P < 0.05. Soy protein replacement of casein in the EtOH diet significantly reduced adenoma progression when compared with the EtOH and EtOH/SPI group (P < 0.05). Tumor reduction in the EtOH/SPI group corresponded to reduced liver injury associated with decreased hepatic Tnfα and Cd14 antigen (Cd14) expression and decreased nuclear accumulation of NF-κB1
