Fig. 7From: Radix puerariae extracts ameliorate paraquat-induced pulmonary fibrosis by attenuating follistatin-like 1 and nuclear factor erythroid 2p45-related factor-2 signalling pathways through downregulation of miRNA-21 expressionEffect of RPE treatment on protein expression of HO-1 and Nrf2 in the lung. a Representative western blots showing HO-1 and Nrf2 protein on day 14 after RPE treatment (1, control group; 2, model group; 3, treatment group). b Statistical summary of the densitometric analyses of HO-1 and Nrf2 expression. Data are means ± SD of three experiments. *P < 0.05 and **P < 0.01 vs the control group; ##P < 0.01 and #P < 0.01 vs the model groupBack to article page
