Investigating intergenerational effects of glucocorticoids

Fisher Benjamin , Sandovici Ionel , Constância Miguel , Miska Eric

Background: Animal studies have reported that exposure to synthetic glucocorticoids (sGCs) may lead to inter- and transgenerational effects on offspring phenotype. However, many of these studies are poorly designed, do not account for possible non-epigenetic confounds, and cannot determine the mechanism(s) by which gamete epimutations are induced.Objectives: Firstly, to determine whether developmental exposure of mice to...

Effects of Developmental Bisphenol A Exposure on Spermatozoal microRNA Expression

Background: Bisphenol A (BPA), a ubiquitous endocrine-disrupting chemical, has been shown to exert transgenerational effects on adiposity, metabolism, and reproductive outcomes in rodents, indicating epigenetic inheritance. Recent studies of other environmental insults (stress and high-fat diet) have demonstrated a mechanistic role for spermatozoal microRNAs in the transgenerational transmission of acquired paternal traits.Objective and hypotheses: To as...
