WKY rats were randomly assigned to either (1) a methyl donor supplemented (SUP) group receiving a diet enriched with higher than usual amounts of methyl donors and cofactors (folic acid, choline, methionine, and Vitamin B12; diet. No. A04062403, Research Diets Inc, New Brunkswick, NJ; termed methyl donor supplemented group (SUP); or (2) a methyl donor depleted (DEP) group fed chow that was 90% depleted of methyl donors (diet no. A04062402, Research Diets Inc, New Brunkswick, NJ).
