Hesperidin alleviates BLM-induced IPF via inhibition of TGF-β1/Smad3/AMPK and IκBα/NF-κB pathways which in turn ameliorate the modulation of oxido-inflammatory markers (Nrf2 and HO-1) and pro-inflammatory markers (TNF-α, IL-1β, and IL-6) to reduce collagen deposition during pulmonary fibrosis.See also Figure 1(Fig.1).
Bleomycin (BLM)-induced PF in Nrf2-knockout (Nrf2<sup>-/-</sup> ) and wild-type (WT) mice and transforming growth factor β1 (TGF-β1)-induced EMT in rat type II alveolar epithelial cell line (RLE-6TN) and human alveolar epithelial cell line (A549) were established to observe the relationship among Nrf2, HMGB1, and EMT by western blot and immunohistochemistry.
Tanshinone IIA Activates Nuclear Factor-Erythroid 2-Related Factor 2 to Restrain Pulmonary Fibrosis via Regulation of Redox Homeostasis and Glutaminolysis.
We conclude that FGF21 inhibits pulmonary fibrosis through activating Nrf-2 pathway, subsequently suppressing oxidative stress, inhibiting ECM deposition and pulmonary fibrogenesis, suggesting that FGF21 has potential as therapeutic agent for treatment of pulmonary fibrosis.
We explore the possible discourse of sinapic acid (SA) against the prevention of bleomycin (BLM)-instigated lung fibrosis in rats through modulation of Nrf2/HO-1 and NF-κB signaling pathways.
Suppression of nuclear factor erythroid 2-related factor 2 via extracellular signal-regulated kinase contributes to bleomycin-induced oxidative stress and fibrogenesis.
This study demonstrates the involvement of Nrf2-Keap1 signaling through which EGCG enhances antioxidant activities and Phase II enzymes with subsequent restraint inflammation during bleomycin-induced pulmonary fibrosis.
