Untargeted LC-MS-Based Metabolomics Reveals Metabolic Fate and Cellular Biochemical Disruptions Induced by 4,4-Diaminodiphenylmethane in Human Skin Fibroblasts.
Human exposure to 4,4'-diaminodiphenylmethane (MDA) occurs predominantly through dermal contact, yet its extra-hepatic biotransformation pathways and the metabolomic disturbances it induces remain poorly characterized. In this study, human skin fibroblasts were incubated with MDA, and untargeted LC-HRMS metabolomics wa...
