Abstract

We used relevant dietary and environmental doses of Vanadium pentoxide (V +5 ) to examine its metabolic impact in vitro and in vivo. Using liquid chromatography-high-resolution mass spectrometry (LC-HRMS), we found significant metabolic perturbations, with similar dose-dependent patterns observed in human lung fibroblasts and male mouse lungs. Alterations in lipid metabolism included inflammatory signaling, elevated hydroxyproline levels, and excessive collagen deposition were present in V +5 -treated lungs. Our findings suggest that low levels of V +5 could trigger pulmonary fibrotic signaling.
