Mode‐of‐Action and Human Relevance Assessment for Diisononyl Phthalate‐Induced Liver Tumors in Rodents

Journal of Applied Toxicology, EarlyView.
ABSTRACT Diisononyl phthalate (DINP) is a high molecular weight phthalate and high production volume chemical. DINP's carcinogenic potential has been investigated in four rodent bioassays, with liver tumors observed in three of the studies. Authoritative assessments have hypothesized that DINP acts through the peroxisome proliferator‐activated receptor
