(Submitter supplied) Stress and glucocorticoid exposure during pregnancy alters neurodevelopment and behavior in offspring, and these effects extend multiple generations through a paternal lineage. The epigenetic mechanisms that govern this transgenerational transmission are unclear. We hypothesized that maternal exposure to multiple courses of sGC in late pregnancy would result in altered miRNA levels in germs cells of male guinea pigs across three generations. more...

(Submitter supplied) It has been demonstrated that males exposed to adversity prior to conception sire offspring exhibiting abnormal behaviour and neuroendocrine function. Epigenetic factors such as microRNA (miRNA) within sperm may be responsible for driving these effects. Synthetic glucocorticoids (sGC) are a class of drug that are commonly prescribed and may have implications for intergenerational transmission. Therefore, we hypothesized that caput and cauda sperm miRNA profiles will be altered following sGC exposure in guinea pigs. more...

(Submitter supplied) First generation animals (F1) were exposed to multiple courses of synthetic glucocorticoids in utero. Animals were then bred to produce second (F2) and third (F3) generation offspring. These animals underwent behavioural assessmenets before sacrifice. In this experiment the prefrontal cortex for F1, F2, and F3 female animals, as well as F1 males (Control and sGC) have been extracted via micro-punch and RNA has been extracted.

(Submitter supplied) NSAIDs and ACE that affect prostaglandin synthesis are widely used by pregnant women. Epidemiological studies have hypothesized a potential relation of testis dysgenesis syndromes such as cryptorchidism and hypospadias to exposure to these molecules during both the first and the second trimesters of gestation. To decipher whether the embryonic gonads themselves are targets for these molecules, we analysed the impact of precocious in utero exposure to NSAIDs and ACE alone or in combination on the early development of the testis during sex determination, using therapeutic doses similar to those administrated in human medications. more...

(Submitter supplied) We examined the hypothesis that prenatal synthetic glucocorticoids (sGC) administration alters DNA methylation signatures in Guinea pig offspring hippocampus and whole blood. Guinea pigs were treated with sGC or saline in late gestation. Genome-wide modifications of DNA methylation were analyzed using reduced representation bisulfite sequencing in juvenile female offspring.

(Submitter supplied) Background: DNA methylation (DNAme) erasure and reacquisition occurs during prenatal male germ cell development; some further remodelling takes place after birth during spermatogenesis. Environmental insults during germline epigenetic reprogramming may affect DNAme, presenting a potential mechanism for transmission of environmental exposures across multiple generations. Objectives: We investigated how germ cell DNAme is impacted by lifetime exposures to diets containing either low or high, clinically relevant, levels of the methyl donor folic acid and whether resulting DNAme alterations were inherited in germ cells of male offspring of subsequent generations. more...

(Submitter supplied) In the context of male reproductive health, epidemiological studies have observed reduced testis size and abnormal sperm counts and morphology in adult men exposed in utero, although these findings are not always repeated. The ambiguity of these reports is confounded by a lack of controlled animal studies investigating the effects of maternal cigarette smoke exposure on male offspring reproductive health. more...

(Submitter supplied) In recent years considerable effort has been devoted to understanding the epigenetic control of sperm development leading to an increased appreciation of the importance of RNA interference pathways, and in particular microRNAs (miRNAs), as key regulators of spermatogenesis and epididymal maturation. It has also been shown that sperm are endowed with an impressive array of miRNA that have been implicated in various aspects of fertilization and embryo development. more...

(Submitter supplied) Parental environmental exposures can strongly influence descendant risks for adult disease. Metabolic disorders arise from the intersection of environmental and genetic risk factors, with epigenetic inheritance being at the center of the familial cycle of transgenerational disease. How paternal high-fat diet changes the sperm chromatin leading to the acquisition of metabolic disease in offspring remains controversial and ill-defined. more...

(Submitter supplied) The pre and postnatal environment can affect both an individual’s risk of adult onset metabolic disease and that of subsequent generations. Although animal models and epidemiological data implicate epigenetic inheritance, little is known of the mechanisms involved. In a robust intergenerational model of developmental programming we demonstrate that the nutritional environment experienced in utero by F1 generation embryos alters the DNA methylome of the F1 adult male germ line in a locus-specific manner, without affecting overall methylation levels. more...
