Pre-reproductive stress in adolescent female rats alters maternal care and DNA methylation patterns across generations

open access: yesStress, 2023
Stress during development affects maternal behavior and offspring phenotypes. Stress in adolescence is particularly consequential on brain development and maturation, and is implicated in several psychiatric disorders.

Epigenetics and transgenerational inheritance

open access: yesThe Journal of Physiology, 2023
AbstractEpigenetic modifications can alter the function of genes. The epigenetics changes are caused by environmental effects, which lead to chemical modifications of the DNA or the chromatin. The mechanisms involve the influence of small interfering siRNAs on gene silencing.

Family Genealogy’s Contributions to the Philosophical Problem of Birth

open access: yesGenealogy, 2018
The central philosophical problem of birth concerns the fact that it is an event necessary for all events. As such, it is the nihilated a priori of itself—in short, it is lost in an abyss of consciousness.

Cumulative Metabolic and Epigenetic Effects of Paternal and/or Maternal Supplementation with Arachidonic Acid across Three Consecutive Generations in Mice

open access: yesCells, 2022
Apart from the known associations between arachidonic acid (AA), weight gain, and neurological and immune function, AA exposure leads to alterations in global and gene-specific DNA methylation (DNAm) and fatty acid (FA) content in human cultured cells ...

Transgenerational effects of UV-B radiation on egg size, fertilization, hatching and larval size of sea urchins Strongylocentrotus intermedius [PDF]

open access: yesPeerJ, 2019
Transgenerational effects are important for phenotypic plasticity and adaptation of marine invertebrates in the changing ocean. Ultraviolet-B (UV-B) radiation is an increasing threat to marine invertebrates.

Epigenetic Transgenerational Inheritance of the Effects of Obesogen Exposure

open access: yesFrontiers in Endocrinology, 2021
Obesity and metabolic disorders have become a worldwide pandemic affecting millions of people. Although obesity is a multifaceted disease, there is growing evidence supporting the obesogen hypothesis, which proposes that exposure to a subset of endocrine
