Fig. 3From: Triptolide ameliorates fine particulate matter-induced podocytes injury via regulating NF-κB signaling pathwayApoptosis rates of podocytes were assessed by flow cytometry. Podocytes were pre-treated with triptolide at 0, 1, 2, 4 mg/L for 1 h and followed by the addition of 200 mg/L PM2.5 for 24 h. Data are expressed as mean ± SEM. n = 3. **P < 0.01 versus untreated cells; #P < 0.05, ##P < 0.01 versus PM2.5 groupBack to article page
