PFAS assay activity and placental cell-type expression

Archived study

Combines PFAS assay activity with placental cell-type expression from five pregnancy IDs. Expanded mappings linked 45 PFOA-associated and 142 PFOS-associated genes to expression; strict human biochemical mappings reduced these counts to seven and 42.

Interpretation and limits

This is not an exposure experiment or placental toxicity test. Small donor numbers, incomplete assay QC and absent matched exposure/outcome data prevent claims about target engagement, safe doses, fetal harm or relative toxicity.

Package and provenance

The unchanged research package comes from upstream Case 30. It includes the archived session, analysis materials, results and figures. The poster uses an AI-generated illustrative photograph. This introduction summarizes archived findings; the analysis was not rerun.

Import provenance

This case was added to the Academic Research category on 2026-10-13, with the archived upstream case recorded as its source. The supplied session export and poster were uploaded without changing their contents. This introduction summarizes the archived findings and was standardized for the repository. The study, external data sources, and scientific results were not rerun or independently reverified for this import.

This GitHub catalog imports the case from the verified Hugging Face snapshot. The session export is referenced through that fixed revision; the cover and introduction are stored in this repository.
