N-Hexane Toxicity In Jurkat T Cells Is Mediated By Reactive Oxygen Species, Catherine Mcdermott, Maria O'Donoghue, James Heffron
Catherine M. McDermott
Here we assess the role of reactive oxygen species (ROS) formation in the manifestation of n-hexane toxicity in Jurkat T-cells and the chemo-protective potential of the antioxidants epigallocatechin-3-gallate (EGCG) and thymoquinone (TQ) against n-hexane toxicity in vitro. n-Hexane is an important industrial solvent and ambient air pollutant. Sub-chronic exposure to n-hexane results in a concentration-dependent increase in ROS formation with a corresponding decrease in Jurkat T-cell proliferation. Results from time–course studies indicate that ROS formation plays a causal role in n-hexane induced alterations in Jurkat T-cell proliferation and membrane integrity. Treatment of cells with EGCG, at a concentration reached in …
