Epigenetic transgenerational inheritance mechanisms that lead to prostate disease

This 2019 Washington rodent study found: “Ancestral exposure to the toxicant vinclozolin induces an epigenetic transgenerational increase in susceptibility to prostate pathology in F3 [male great-grandchildren] generation rats. These results are in agreement with previous studies which found a transgenerational increase in rates of prostatic epithelial atrophy, cystic hyperplasia, and prostatitis in the transgenerational F3 … Continue reading Epigenetic transgenerational inheritance mechanisms that lead to prostate disease

Burying human transgenerational epigenetic evidence

The poor substitutes for evidence in this 2018 US study guaranteed that human transgenerational epigenetically inherited effects wouldn’t be found in the generations that followed after prenatal diethylstilbestrol (DES) exposure: “A synthetic, nonsteroidal estrogen, DES was administered to pregnant women under the mistaken belief it would reduce pregnancy complications and losses. From the late 1930s … Continue reading Burying human transgenerational epigenetic evidence

Epigenetic transgenerational inheritance of ovarian disease

This 2018 Washington rodent study investigated ovarian disease in F3 great-granddaughters caused by their F0 great-grandmothers’ exposures to DDT or vinclozolin while pregnant: “Two of the most prevalent ovarian diseases affecting women’s fertility and health are Primary Ovarian Insufficiency (POI) and Polycystic Ovarian Syndrome (PCOS). POI is characterized by a marked reduction in the primordial … Continue reading Epigenetic transgenerational inheritance of ovarian disease

The imperative of human transgenerational studies

The coauthor of: A self-referencing study of transgenerational epigenetic inheritance; and A review of epigenetic transgenerational inheritance of reproductive disease pointed out the opportunity for the researchers of A seasonal epigenetic effect of conception on BMI to have their work make a difference in their field: “The ability of environmental epigenetics to promote an adaptive … Continue reading The imperative of human transgenerational studies

Transgenerational epigenetic effects of maternal obesity during pregnancy

This 2018 Belgian review subject was in part the transgenerational epigenetic effects of maternal obesity during pregnancy. The subject was tailored for the journal in which it appeared, Atherosclerosis, so other transgenerationally inherited epigenetic effects weren’t reviewed: “The transgenerational impact of these alterations in methylation patterns are only shown in animal studies with HFD [high-fat … Continue reading Transgenerational epigenetic effects of maternal obesity during pregnancy

A self-referencing study of transgenerational epigenetic inheritance

This 2018 Washington rodent study subject was transgenerational epigenetic inheritance of disease caused by a fungicide that’s been phased out or banned for over a decade: “This study was designed to help understand how three different epigenetic processes in sperm are correlated with vinclozolin-induced epigenetic transgenerational inheritance of disease. Most DMRs [differential DNA-methylated regions] identified … Continue reading A self-referencing study of transgenerational epigenetic inheritance

Transgenerationally inherited epigenetic effects of fetal alcohol exposure

The fourth paper of Transgenerational epigenetic inheritance week was a 2016 German rodent study of transgenerational epigenetic effects of alcohol: “We investigated 2 generations of offspring born to alcohol-treated mothers. Here, we show that memory impairment and reduced synthesis of acetylcholine occurs in both F1 (exposed to ethanol in utero) and F2 generation (never been exposed to … Continue reading Transgenerationally inherited epigenetic effects of fetal alcohol exposure

Transgenerational pathological traits induced by prenatal immune activation

The third paper of Transgenerational epigenetic inheritance week was a 2016 Swiss rodent study of immune system epigenetic effects: “Our study demonstrates for, we believe, the first time that prenatal immune activation can negatively affect brain and behavioral functions in multiple generations. These findings thus highlight a novel pathological aspect of this early-life adversity in shaping … Continue reading Transgenerational pathological traits induced by prenatal immune activation

Experience-induced transgenerational programming of neuronal structure and functions

The second paper of Transgenerational epigenetic inheritance week was a 2017 German/Israeli review focused on: “The inter- and transgenerational effects of stress experience prior to and during gestation..the concept of stress-induced (re-)programming in more detail by highlighting epigenetic mechanisms and particularly those affecting the development of monoaminergic transmitter systems, which constitute the brain’s reward system..we offer … Continue reading Experience-induced transgenerational programming of neuronal structure and functions

Transgenerational effects of early environmental insults on aging and disease

The first paper of Transgenerational epigenetic inheritance week was a 2017 Canadian/Netherlands review that’s organized as follows: “First, we address mechanisms of developmental and transgenerational programming of disease and inheritance. Second, we discuss experimental and clinical findings linking early environmental determinants to adverse aging trajectories in association with possible parental contributions and sex-specific effects. Third, we … Continue reading Transgenerational effects of early environmental insults on aging and disease
