Modeling early germline immunization after horizontal transfer of transposable elements reveals internal piRNA cluster heterogeneity

BMC Biology, 2023
Background A fraction of all genomes is composed of transposable elements (TEs) whose mobility needs to be carefully controlled. In gonads, TE activity is repressed by PIWI-interacting RNAs (piRNAs), a class of small RNAs synthesized by heterochromatic ...

Obesity and endocrine-disrupting chemicals

Endocrine Connections, 2021
Obesity is now a worldwide pandemic. The usual explanation given for the prevalence of obesity is that it results from consumption of a calorie dense diet coupled with physical inactivity.

Transgenerational Effects of Prenatal Endocrine Disruption on Reproductive and Sociosexual Behaviors in Sprague Dawley Male and Female Rats

Toxics, 2022
Endocrine-disrupting chemicals (EDCs) lead to endocrine and neurobehavioral changes, particularly due to developmental exposures during gestation and early life.

Association of Prenatal Famine Exposure With Inflammatory Markers and Its Impact on Adulthood Liver Function Across Consecutive Generations

Frontiers in Nutrition, 2022
Although there has been increasing recognition that famine exposure in the fetal stage damages liver function in adulthood, this deteriorated effect could be extended to the next generation remains vague.

Intergenerational adaptations to stress are evolutionarily conserved, stress-specific, and have deleterious trade-offs

eLife, 2021
Despite reports of parental exposure to stress promoting physiological adaptations in progeny in diverse organisms, there remains considerable debate over the significance and evolutionary conservation of such multigenerational effects.

Multi- and Transgenerational Effects of Developmental Exposure to Environmental Levels of PFAS and PFAS Mixture in Zebrafish (Danio rerio)

Toxics, 2022
Per- and polyfluoroalkyl substances (PFASs) are ubiquitous in the environment and are tied to myriad health effects. Despite the phasing out of the manufacturing of two types of PFASs (perfluorosulfonic acid (PFOS) and perfluorooctanoic acid (PFOA ...

Transgenerational epigenetic inheritance [PDF]

Current Biology, 2003
What is it? If you thought all heritable traits are written in the DNA sequence, think again! We have come to realize that, at some alleles, the epigenetic state of the DNA can also be inherited. This is indicated by analysis of alleles where the establishment of the epigenetic state is stochastic.
