The skin is one of the large organs in the human body and the most exposed to outdoor contaminants such as particulate matter<2.5µm (PM). Recently, we reported that PMinduced cellular macromolecule disruption of lipids, proteins, and DNA, via reactive oxygen species, eventually causing cellular apoptosis of human keratinocytes. In this study, the ethanol extract offruit (EECF) showed anti-oxidant effect against PM-induced cellular oxidative stress. EECF protected cells against PM-induced DNA damage, lipid peroxidation, and protein carbonylation. PMup-regulated intracellular and mitochondrial Calevels excessively, which led to mitochondrial depolarization and cellular apoptosis. However, EECF suppressed the PM-induced excessive Caaccumulation and inhibited apoptosis. The data confirmed that EECF greatly protected human HaCaT keratinocytes from PM-induced oxidative stress.
