Mitochondrial GRIM19 Loss Induces Liver Fibrosis through NLRP3/IL33 Activation via Reactive Oxygen Species/NF-кB Signaling. J Clin Transl Hepatol 2024; 12:539-550. [PMID: 38974954 PMCID: PMC11224902 DOI: 10.14218/jcth.2023.00562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 04/24/2024] [Accepted: 05/11/2024] [Indexed: 07/09/2024] Open
Abstract
Background and Aims Hepatic fibrosis (HF) is a critical step in the progression of hepatocellular carcinoma (HCC). Gene associated with retinoid-IFN-induced mortality 19 (GRIM19), an essential component of mitochondrial respiratory chain complex I, is frequently attenuated in various human cancers, including HCC. Here, we aimed to investigate the potential relationship and underlying mechanism between GRIM19 loss and HF pathogenesis. Methods GRIM19 expression was evaluated in normal liver tissues, hepatitis, hepatic cirrhosis, and HCC using human liver disease spectrum tissue microarrays. We studied hepatocyte-specific GRIM19 knockout mice and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein-9 (Cas9) lentivirus-mediated GRIM19 gene-editing in murine hepatocyte AML12 cells in vitro and in vivo. We performed flow cytometry, immunofluorescence, immunohistochemistry, western blotting, and pharmacological intervention to uncover the potential mechanisms underlying GRIM19 loss-induced HF. Results Mitochondrial GRIM19 was progressively downregulated in chronic liver disease tissues, including hepatitis, cirrhosis, and HCC tissues. Hepatocyte-specific GRIM19 heterozygous deletion induced spontaneous hepatitis and subsequent liver fibrogenesis in mice. In addition, GRIM19 loss caused chronic liver injury through reactive oxygen species (ROS)-mediated oxidative stress, resulting in aberrant NF-кB activation via an IKK/IкB partner in hepatocytes. Furthermore, GRIM19 loss activated NLRP3-mediated IL33 signaling via the ROS/NF-кB pathway in hepatocytes. Intraperitoneal administration of the NLRP3 inhibitor MCC950 dramatically alleviated GRIM19 loss-driven HF in vivo. Conclusions The mitochondrial GRIM19 loss facilitates liver fibrosis through NLRP3/IL33 activation via ROS/NF-кB signaling, providing potential therapeutic approaches for earlier HF prevention.

Abstract
OBJECTIVE To investigate the protective effect of NDUFA13 protein against acute liver injury and liver fibrosis in mice and explore the possible mechanisms. METHODS BALB/C mice (7 to 8 weeks old) were divided into normal group, CCl4 group, CCl4+AAV-NC group and CCl4+AAV-NDU13 group (n=18). Mouse models of liver fibrosis were established by intraperitoneal injection of CCl4 twice a week for 3, 5 or 7 weeks, and the recombinant virus AAV8-TBG-NC or AAV8-TBG-NDUFA13 was injected via the tail vein 7-10 days prior to CCl4 injection. After the treatments, pathological changes in the liver of the mice were observed using HE and Masson staining. Hepatic expression levels of NDUFA13 and α-SMA were detected with Western blotting, and the coexpression of NDUFA13 and NLRP3, TNF-α and IL-1β, and α-SMA and collagen Ⅲ was analyzed with immunofluorescence assay. RESULTS HE and Masson staining showed deranged liver architecture, necrotic hepatocytes and obvious inflammatory infiltration and collagen fiber deposition in mice with CCl4 injection (P < 0.001). NDUFA13 expression markedly decreased in CCl4-treated mice (P < 0.001), while a significant reduction in inflammatory aggregation and fibrosis was observed in mice with AAV-mediated NDUFA13 overexpression (P < 0.001). In CCl4+AAV-NDU13 group, immunofluorescence assay revealed markedly weakened activation of NLRP3 inflammasomes (P < 0.001), significantly decreased TNF-α and IL-1β secretion (P < 0.001), and inhibited hepatic stellate cell activation (P < 0.05) and collagen formation in the liver (P < 0.001). CONCLUSION Mitochondrial NDUFA13 overexpression in hepatocytes protects against CCl4- induced liver fibrosis in mice by inhibiting activation of NLRP3 signaling.

Abstract
OBJECTIVE To investigate the role of hepatocyte mitochondrial NDUFA13 loss in the liver fibrogenesis in mice and explore the possible mechanisms. OBJECTIVE We used liver-specific NDUFA13 heterozygous knockout mouse models (NDUFA13fl/-; Alb-Cre) established previously by intercrossing NDUFA13fl/fl and Alb-Cre mice, with their littermate control NDUFA13fl/fl mice as the control (n=8). The mice were euthanized at the age of 4 weeks and 2 years, and the liver tissues were collected for HE and Masson staining to observe the pathological changes and fibrosis phenotypes. Western blotting was performed to detect the expression of NDUFA13 protein in the liver tissues, and the infiltration of F4/80+ macrophages and the expressions of TGF-β1, TNF-α and IL-1β were analyzed by immunofluorescence assay. The expression levels of α-SMA, matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of matrix metalloproteases 1 (TIMP-1), collagen-Ⅰ and collagen-Ⅲ were assayed by immunohistochemistry. OBJECTIVE HE and Masson staining showed obvious inflammatory infiltration but no significant fibrosis in the liver tissues of 4-week-old NDUFA13fl/- mice, but severe liver damage with massive fibrosis was observed in 2-year-old NDUFA13fl/- mice. NDUFA13 expression in 2-year-old NDUFA13fl/- mice markedly decreased compared with that in the control NDUFA13fl/fl mice as shown by Western blotting (P < 0.05). Immunohistochemistry showed obvious infiltration of F4/80+ macrophages in the liver tissue with a large amount of TGF-β1 production (P < 0.05) and TNF-α and IL-1β secretions in NDUFA13fl/- mice (P < 0.05). NDUFA13 knockout obviously promoted α-SMA expression (P < 0.05) and collagen-Ⅰ and collagen-Ⅲ deposition (P < 0.05) while significantly decreased MMP-9 and increased TIMP-1 expression in the liver (P < 0.05). OBJECTIVE Hepatocytes-specific NDUFA13 deficiency can trigger spontaneous and chronic liver fibrosis phenotypes in mice probably in association with abnormal activation of hepatic stellate cells induced by macrophages and inflammatory factors.
