Nanoplastic at environmentally relevant concentrations activates a germline <i>mir-240-rab-5</i> signaling cascade to affect the secreted ligands associated with transgenerational toxicity induction in <i>C. elegans</i>

Summary

Researchers found that nanoplastics at levels commonly found in the environment activated a specific genetic signaling pathway in roundworms that caused toxic effects passed down across multiple generations. The nanoplastics triggered changes in gene regulation that affected offspring who were never directly exposed to the plastic particles. This is particularly alarming because it suggests that nanoplastic exposure could have health consequences not just for the individual exposed but for their children and grandchildren through inherited genetic changes.
