Immunoblotting of nuclear extracts from gastric mucosa with antibodies to PCNA and Cyclin D1 in the 4 groups as indicated in lanes 1-4 (A) and values normalized by arbitrarily setting the densitometry of control to 1.0 (B). β-actin staining was performed to ensure an equal loading. The results indicated are in percentage above the control value and are representative of four independent experiments. ^aP < 0.05 vs control animals, ^cP < 0.05 vs ethanol-treated animals.
