p53-dependent repression of DPYD expression in intact liver and impact of human p53 polymorphic variants on liver expression of DPYD. (A and B) Fold-change in expression of DPYD mRNA and protein in livers of p53+/+ (wild-type,) and p53−/− mice. P-values are determined Multiple t test.and one way Anova [NT vs 5-FU in p53+/+ mice for DPYD mRNA is p = 0.08; DPYD protein p = 0.0021and NT vs 5-FU in p53−/− mice for DPYD mRNA is p = 0.040; DPYD protein p = 0.09] (C) HUPKI Codon R72P MEF-R/R or MEF-P/P were treated with 5-FU (384 μM) up to 24 hr and DPYD protein expression in MEF-P/P or MEF-R/R allele was evaluated by western blot. (D) DPYD protein expression in Normal human fibroblast cell line harboring Codon R72P polymorphism, i.e., NHF P/P and NHF R/R is evaluated by western blot after treatment with 5-FU for the indicated times.
