Racial Disparities in Epigenetic Aging of the Right vs Left #Colon
There are well-documented racial differences in age-of-onset and laterality of colorectal cancer. Epigenetic age acceleration is postulated to be an underlying factor. However, comparative studies of side-specific colonic tissue epigenetic aging are lacking. Here, we performed DNA methylation analysis of matched right and left biopsies of normal colon from 128 individuals. Among African Americans (n = 88), the right colon showed accelerated epigenetic aging as compared to … Continue reading Racial Disparities in Epigenetic Aging of the Right vs Left #Colon
