In VitroHighlightedMolecular hydrogen protects against oxidative stress‑induced RAW 264.7 macrophage cells through the activation of Nrf2 and inhibition of MAPK signaling pathwayMHID-35801392020Molecular & Cellular ToxicologyRahima Begum, Cheol‑Su Kim, Ailyn Fadriquela, Johny Bajgai, Xingyu Jing, Dong‑Heui Kim, et al.Background: Oxidative stress is involved in the development of many inflammatory, metabolic and aging diseases. Objective: In this study we investigated, the protective effects of H2 on RAW 264.7 macrophage cell against LPS-and H2O2-induced oxidative stress by the inhibition of MAPK pathway and also activate the Nrf2 pathway. Results: Our results showed H2 increased the macrophage cell prolifera
