Epigenetics of pregnancy: looking beyond the DNA code

WebDownstream epigenetic analyses on specific cell types revealed patterns of epigenetic modifications exclusive to certain brain cell types. Most notably, there was an association between hydroxymethylation, an intermediate state in the reaction responsible for DNAm, and gene expression in the inhibitory neurons, but not in the other subtypes. WebObjectives: Recent evidence from the fields of microbiology and immunology, as well as a small number of human sepsis studies, suggest that epigenetic regulation may play a central role in the pathogenesis of sepsis. The term "epigenetics" refers to regulatory mechanisms that control gene expression but are not related to changes in DNA sequence.
