This 2020 study followed up The transgenerational impact of Roundup exposure using the Washington State Unversity research group’s most recent methodology in DEET and permethrin cause transgenerational diseases:
“The herbicide glyphosate has been shown to promote epigenetic transgenerational inheritance of pathology and disease in subsequent great-grand offspring (F3 generation). The current study was designed to identify epigenetic biomarkers for glyphosate-induced transgenerational diseases using an epigenome-wide association study.
Pathologies investigated included prostate disease [13 of 44 subjects], kidney disease [11 of 44], obesity [19 of 45], and presence of multiple disease [10 of 45]. Sperm were collected from F3 glyphosate lineage males and used to identify specific differential DNA methylation regions (DMRs) and differential histone retention sites (DHRs).
The number of DHRs were less than the number of DMRs, and DHRs were found to have disease specificity. The combination of DMRs and DHRs is anticipated to facilitate pathology diagnosis.
Low sample number is a limitation in the current analysis. Potential higher variability in data needs to be considered.
This is one of the first observations of DHRs as potential biomarkers for disease. The current study used glyphosate induction of transgenerational disease as a proof of concept such environmental biomarkers can be identified and potentially used as diagnostics for disease susceptibility in the future.”
