Fig. 7From: Polypropylene nanoplastic exposure leads to lung inflammation through p38-mediated NF-κB pathway due to mitochondrial damagea Representative images of mitochondrial (green) and mitochondrial ROS (red) stained PP-exposed A549 cells that were treated with 200 nM for 30 min. b Quantified staining intensities for mitochondrial ROS. c Total ROS production in PP-exposed A549 cells. d Inflammatory cytokine levels of TNF-α, IL-1β, and IL-6 in cell lysate of PP-exposed A549 cells. e Relative density analysis of TNF-α, IL-1β, and IL-6. f Cell viability assessment by MTT assay. Data were normalized against β-actin. Data are means ± SD (n = 3 per group). #P ≤ 0.05; ##P ≤ 0.01; ###P ≤ 0.001 vs. VC. Scale bar 20 μmBack to article page
