Fluorofenidone Inhibits UUO/IRI-Induced Renal Fibrosis by Reducing Mitochondrial Damage
Oxid Med Cell Longev 2022 Mar 20;2022:2453617.PMID:35355864DOI:10.1155/2022/2453617.
Objective: Mitochondrial damage contributes to extracellular matrix (ECM) deposition and renal fibrosis. In this study, we aimed (1) to investigate whether Fluorofenidone (AKF-PD) can attenuate mitochondrial damage in two renal fibrosis models: unilateral ureteral obstruction (UUO) and renal ischemia-reperfusion injury (IRI), and (2) to explore the underlying mechanism. Method: Mitochondrial damage and renal lesions were analyzed in the UUO and IRI models. Mitochondrial energy metabolism, mitochondrial biogenesis, and oxidative stress were measured to assess the effect of AKF-PD on mitochondrial damage and to explore the underlying mechanism. In addition, HK-2 cells were stimulated with TGF-β with and without AKF-PD. The mitochondrial morphology, mtROS, ATP contents, and redox-related proteins were then examined. Results: In both UUO and IRI models, AKF-PD relieved renal fibrosis, maintained mitochondrial structure, and increased mitochondrial DNA copy numbers. The protection was associated with (1) sustaining mitochondrial energy metabolism, evident by elevations of tricarboxylic acid (TCA) cycle enzymes and mitochondrial respiratory chain complexes; (2) improving mitochondrial biogenesis with increases of TFAM, NRF1, PGC-1α, and SIRT1; and (3) reducing mitochondrial oxidative stress likely via regulating SOD2, SIRT3, and NOX4 expressions. In HK-2 cells treated with TGF-β, AKF-PD protected mitochondria along with improving mitochondrial morphology, enhancing ATP production, reducing mtROS, and regulating SOD2, SIRT3, and NOX4 expression. Conclusion: We demonstrate that AKF-PD inhibited renal fibrosis at least in part via protecting mitochondria from damages developed in the UUO and IRI models. The mitochondrial protection was associated with sustaining mitochondrial energy metabolism, improving mitochondrial biogenesis, and reducing mitochondrial oxidative stress. This research verified the protective effect of AKF-PD on mitochondria in the UUO and IRI models and elaborated the underlying mechanism.
Fluorofenidone attenuates pulmonary inflammation and fibrosis via inhibiting the activation of NALP3 inflammasome and IL-1β/IL-1R1/MyD88/NF-κB pathway
J Cell Mol Med 2016 Nov;20(11):2064-2077.PMID:27306439DOI:10.1111/jcmm.12898.
Interleukin (IL)-1β plays an important role in the pathogenesis of idiopathic pulmonary fibrosis. The production of IL-1β is dependent upon caspase-1-containing multiprotein complexes called inflammasomes and IL-1R1/MyD88/NF-κB pathway. In this study, we explored whether a potential anti-fibrotic agent Fluorofenidone (FD) exerts its anti-inflammatory and anti-fibrotic effects through suppressing activation of NACHT, LRR and PYD domains-containing protein 3 (NALP3) inflammasome and the IL-1β/IL-1R1/MyD88/NF-κB pathway in vivo and in vitro. Male C57BL/6J mice were intratracheally injected with Bleomycin (BLM) or saline. Fluorofenidone was administered throughout the course of the experiment. Lung tissue sections were stained with haemotoxylin and eosin and Masson's trichrome. Cytokines were measured by ELISA, and α-smooth muscle actin (α-SMA), fibronectin, collagen I, caspase-1, IL-1R1, MyD88 were measured by Western blot and/or RT-PCR. The human actue monocytic leukaemia cell line (THP-1) were incubated with monosodium urate (MSU), with or without FD pre-treatment. The expression of caspase-1, IL-1β, NALP3, apoptosis-associated speck-like protein containing (ASC) and pro-caspase-1 were measured by Western blot, the reactive oxygen species (ROS) generation was detected using the Flow Cytometry, and the interaction of NALP3 inflammasome-associated molecules were measured by Co-immunoprecipitation. RLE-6TN (rat lung epithelial-T-antigen negative) cells were incubated with IL-1β, with or without FD pre-treatment. The expression of nuclear protein p65 was measured by Western blot. Results showed that FD markedly reduced the expressions of IL-1β, IL-6, monocyte chemotactic protein-1 (MCP-1), myeloperoxidase (MPO), α-SMA, fibronectin, collagen I, caspase-1, IL-1R1 and MyD88 in mice lung tissues. And FD inhibited MSU-induced the accumulation of ROS, blocked the interaction of NALP3 inflammasome-associated molecules, decreased the level of caspase-1 and IL-1β in THP-1 cells. Besides, FD inhibited IL-1β-induced the expression of nuclear protein p65. This study demonstrated that FD, attenuates BLM-induced pulmonary inflammation and fibrosis in mice via inhibiting the activation of NALP3 inflammasome and the IL-1β/IL-1R1/MyD88/ NF-κB pathway.
Fluorofenidone inhibits epithelial-mesenchymal transition in human lens epithelial cell line FHL 124: a promising therapeutic strategy against posterior capsular opacification
Arq Bras Oftalmol 2021 May-Jun;84(3):258-266.PMID:33567029DOI:10.5935/0004-2749.20210040.
Purpose: The present study aimed to investigate the inhibitory effect of Fluorofenidone against transforming growth factor β2-induced proliferation and epithelial-mesenchymal transition in human lens epithelial cell line FHL 124 and its potential mechanism. Methods: We evaluated the effect of Fluorofenidone on proliferation and epithelial-mesenchymal transition of human lens epithelial cell line FHL 124 in vitro. After treatment with 0, 0.1, 0.2, 0.4, 0.6, and 1.0 mg/mL Fluorofenidone, cell proliferation was measured via MTT assay. Cell viability was evaluated by lactate dehydrogenase activity from damaged cells. FHL 124 cells were treated with different transforming growth factor β2 concentrations (0-10 ng/mL) for 24 h and the expression of CTGF, α-SMA, COL-I, E-cadherin, and Fn were detected via quantitative polymerase chain reaction and Western blot analysis. After treatment with 0, 0.2, and 0.4 mg/ml Fluorofenidone, the expressions of transforming growth factor β2 and SMADs were detected with real-time polymerase chain reaction and Western blot analysis. Expressions of CTGF, α-SMA, COL-I, and Fn were analyzed by immunocytochemistry assay. Results: The viability of FHL 124 cells was not inhibited when the Fluorofenidone concentration was ≤0.4 mg/mL after the 24h treatment. Cytotoxicity was not detected via lactate dehydrogenase assay after the 24h and 36h treatment with 0.2 and 0.4 mg/mL Fluorofenidone. Transforming growth factor β2 increased mRNA and protein expression of CTGF, α-SMA, COL-I, and Fn. However, Fluorofenidone significantly suppressed expression of SMADs, CTGF, α-SMA, COL-I, and Fn in the absence or presence of transforming growth factor β2 stimulation. Conclusions: Fluorofenidone significantly inhibited expression of SMADs, CTGF, α-SMA, COL-I, and Fn in FHL 124 cells. Due to noncompliance in infants, Fluorofenidone may become a novel therapeutic drug against posterior capsular opacification in infants.
Fluorofenidone protects against acute kidney injury
FASEB J 2019 Dec;33(12):14325-14336.PMID:31661638DOI:10.1096/fj.201901468RR.
Cisplatin (CP) is one of the most effective chemotherapeutics in the treatment of human cancers. However, the beneficial effects of CP are limited by the toxic effects, especially nephrotoxicity. Fluorofenidone (AKFPD) is a promising multifunctional antifibrosis pyridinone drug discovered by our group. But there is no evidence of its protective effects against acute kidney injury (AKI). Therefore, we investigated the protective effects of AKFPD on CP-induced AKI in vivo and in vitro. Compared with the model group, treatment with AKFPD effectively ameliorated kidney damages. In order to elucidate the mechanisms, we discovered that AKFPD treatment notably alleviated generation of reactive oxygen species, reduced the phosphorylation levels of MAPKs (ERK1 and 2, JNKs, and p38), suppressed inflammatory response, inhibited apoptosis, and abated the expression of CP transporters (organic cation transporter 2 and copper transport protein 1) compared with the model group. Moreover, because renal ischemia reperfusion injury (IRI)-induced AKI and LPS-induced AKI are the major models representative of renal transplantation-correlated AKI and sepsis-related AKI, which are also the main causes of AKI, we have also proved the effectiveness of AKFPD on these models. In conclusion, these findings suggest that AKFPD is a potent drug for CP-, IRI-, and LPS-caused AKI and elucidate the underlying mechanism.-Jiang, Y., Quan, J., Chen, Y., Liao, X., Dai, Q., Lu, R., Yu, Y., Hu, G., Li, Q., Meng, J., Xie, Y., Peng, Z., Tao, L.

Idiopathic pulmonary fibrosis is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia of unknown cause. Interleukin (IL)-11 plays an important role in the pathogenesis of idiopathic pulmonary fibrosis. In this study, we explore whether a potential antifibrotic agent Fluorofenidone (FD) exerts its anti-inflammatory and antifibrotic effects through suppressing activation of the IL-11/MEK/ERK signaling pathway in vivo and in vitro. Male C57BL/6 J mice were intratracheally injected with bleomycin or saline. Fluorofenidone was administered throughout the course of the experiment. Lung tissue sections were stained with hemotoxylin and eosin, and Masson trichrome. Cytokines were measured using the enzyme-linked immunosorbent assay. The α-smooth muscle actin (α-SMA), fibronectin, and collagen I were measured using immunohistochemistry, and the phosphorylated extracellular signal-regulated kinase, phosphorylated mitogen-activated protein kinase, IL-11RA, and gp130 were measured using Western blot. The RAW264.7 cells and the normal human lung fibroblasts were treated with IL-11 and/or FD, IL-11RA-siRNA, or MEK inhibitor. The expressions of phosphorylated extracellular signal-regulated kinase, phosphorylated mitogen-activated protein kinase, IL-11RA, gp130, α-SMA, fibronectin, and collagen I were measured using Western blot and/or real-time polymerase chain reaction, and the cytokines were measured using enzyme-linked immunosorbent assay. Results showed that FD markedly reduced the expressions of IL-8, IL-18, IL-11, monocyte chemotactic protein-1, α-SMA, fibronectin, and collagen I in mice lung tissues. In addition, FD attenuated IL-11-induced expressions of α-SMA, fibronectin, and collagen I and inhibited IL-11RA, gp130, and phosphorylation of the ERK and MEK protein expression, as well as reduced the expressions of IL-8, IL-18, and monocyte chemotactic protein-1 in vitro. This study demonstrated that FD attenuated bleomycin-induced pulmonary inflammation and fibrosis in mice by inhibiting the IL-11/MEK/ERK signaling pathway.
