This 2019 Washington State University rodent study from Dr. Michael Skinner’s lab found: “A cascade of epigenetic alterations initiated in the PGCs [primordial germ cells] appears to be required to alter the epigenetic programming during spermatogenesis to modify the sperm epigenome involved in the transgenerational epigenetic inheritance phenomenon. Following fertilization there is a DNA methylation … Continue reading Another important transgenerational epigenetic inheritance study

The transgenerational impact of Roundup exposure

The latest 2019 Washington State University rodent study from Dr. Michael Skinner’s lab found adverse effects in the grand-offspring and great-grand-offspring following their ancestor’s exposure during pregnancy to the world’s most commonly used herbicide: “Using a transient exposure of gestating F0 generation female rats found negligible impacts of glyphosate on the directly exposed F0 generation, … Continue reading The transgenerational impact of Roundup exposure

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

gettingwell4 4-5 stars Advanced knowledge, Epigenetics, Stress , , ,

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

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

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
