Paraquat strengthens lipid peroxidation in human respiratory epithelial cells. A The representative images of immunofluorescence staining of 4-HNE in vehicle or 500 μM PQ-treated BEAS-2B cells, Scale bar: 50 μm; The statistical histograms were shown on (B). C MDA adduct levels in the cell lysates were measured by MDA assay kit. D-E The representative images and statistical histograms of Bodipy staining in BEAS-2B cells with 500 μM PQ treatment in the presence or absence of 100 μM DFO; DAPI was used for nuclear staining; Scale bar: 25 μm. ^★★P < 0.01 versus control group or between indicated groups
