Scientists at McGill University, Canada reported that folate deficiency in a father’s diet could increase birth defects in the offspring by altering sperm epigenome. These defects include craniofacial and musculoskeletal malformations. The scientists fed male mice either a folate-deficient or folate-sufficient diet throughout life and then performed genome-wide DNA methylation analysis and subsequent functional analysis to identify differential methylation in sperm of genes implicated in development, and chronic diseases such as cancer, diabetes, autism and schizophrenia. They found that >300 [more…]
