This may predispose the offspring's mammary glands to be more susceptible to carcinogenesis. The purpose of this study was to examine the effect of a maternal high-fat diet on the regulation of p16 (INK4a) gene expression in the mammary gland of rat offspring. Timed-pregnant Sprague-Dawley rats were fed one of the two diets, a control (C, 16% of fat) or a high fat (HF, 45% of fat) diet, throughout gestation and lactation and sacrificed at 12 weeks of age. Compared with C, HF offspring showed a decrease of p16 (INK4a) gene expression in the mammary gland at both mRNA and protein levels. Chromatin immunoprecipitation (ChIP) assay demonstrated that the downregulation of p16 (INK4a) transcription in HF offspring was associated with reduced acetylation of histone H4 and increased recruitment of histone deacetylase 3 (HDAC3) within the p16 (INK4a) promoter region, but was not associated with acetylation of histone H3 or HDAC1. Methylated DNA immunoprecipitation (MeDIP) did not detect differences in methylation at different regions of the p16 (INK4a) gene between C and HF offspring. We conclude that maternal high fat exposure represses p16 (INK4a) gene expression in the mammary gland of offspring through changes of histone modifications and HDAC3 binding activity within the regulatory regions of the p16 (INK4a) gene."xsd:string |
