The research reinforces that transgenerational disease can be transmitted via epigenetic changes in the germline from exposed gestational females.

A long-running rat study shows that disease persists across kidneys, reproductive organs, and other systems, intensifying in later generations and producing lethal birth outcomes in some lineages.

Toxin levels were chosen to reflect real-world human risk, underscoring the relevance of germline sensitivity to environmental chemicals.

Co-authors include Korolenko as lead author, alongside Nilsson and De Santos, with Nilsson cited among the collaborators.

Germline epigenetic programming suggests changes can be as stable as genetic mutations, implying long-term public health implications.

Across 20 generations, researchers observed persistent disease and higher mortality during birth in the later generations, including mothers and pups.

Using conservative toxin doses well below typical human exposure, the study identifies germline (sperm and egg) changes as the mechanism driving inherited risk.

The study builds on prior transgenerational work, expanding from 10 to 20 generations to reinforce the concept of epigenetic disease transmission.

The broader message points toward preventative medicine and the importance of understanding environmental contributors to chronic diseases.

Published in the Proceedings of the National Academy of Sciences, the work by Skinner and colleagues extends two decades of research in epigenetic inheritance.

The findings align with concerns about rising chronic disease rates and the potential health impact of environmental chemicals used in agriculture and industry.

A notable rat study shows a single in utero exposure to vinclozolin can drive disease risk for up to 20 generations through epigenetic inheritance in germline cells.
