Abstract
Obesity is a low-grade chronic inflammation induced by the pathological expansion of adipocytes which allows the development of obesity-associated metabolic diseases like type 2 diabetes mellitus (T2D) and non-alcoholic fatty liver disease (NAFLD). However, mechanisms regulating adipocyte inflammation remain poorly understood. Here, we observed that TRIM8 was upregulated in adipocyte inflammation and insulin resistance while DUSP14 was downregulated. TRIM8 deficiency and DUSP14 over-expression decreased the level of inflammatory cytokines, increased glucose uptake content, and improved insulin signalling transduction compared to LPS treatment alone. Conversely, silencing DUSP14 increased the expression of inflammatory cytokines. It decreased the glucose uptake content and the phosphorylation level of proteins involved in insulin signalling, further impairing insulin signalling and aggravating insulin resistance. Furthermore, The decreased level of inflammatory cytokines, increased glucose uptake, and improved insulin signalling transduction caused by TRIM8 deficiency were reversed by down-regulated DUSP14. Collectively, our findings revealed that TRIM8 can regulate adipocyte inflammation and insulin resistance by regulating the MAPKs pathway which is dependent on DUSP14.

Abstract
Cervical cancer (CC) is a malignant tumor primarily caused by the persistent infection with high-risk strains of human papillomavirus. This study investigates the aberrant expression of Tripartite Motif Containing 8 (TRIM8) in CC and its impact on cell proliferation, invasion, and migration. Expression levels of TRIM8, Proliferating Cell Nuclear Antigen, and Suppressor of Cytokine Signaling 1 (SOCS1) were assessed in CC cell lines. CC cells were transfected with si-TRIM8, followed by cell counting kit-8 (CCK-8) assay, colony formation assay, and Transwell assay. Protein immunoprecipitation assay was employed to examine TRIM8's binding with SOCS1, and the ubiquitination level of SOCS1 was determined after MG132 treatment. Rescue experiments were conducted using si-SOCS1 and si-TRIM8 in combination. Results indicate upregulation of TRIM8 in CC cells. Inhibition of TRIM8 suppressed cell viability, proliferation, invasion, and migration. TRIM8 promoted CC cell proliferation, invasion, and migration of CC cells through ubiquitination-mediated degradation of SOCS1. Inhibition of SOCS1 partially reversed the inhibitory effects of si-TRIM8 on the proliferation, invasion, and migration of CC cells. In conclusion, TRIM8 enhances CC cell proliferation, invasion, and migration via ubiquitination-mediated degradation of SOCS1.

Abstract
The occurrence and development of ophthalmic diseases are related to the dysfunction of eye tissues. Ubiquitin is an important form of protein post-translational modification, which plays an essential role in the occurrence and development of diseases through specific modification of target proteins. Ubiquitination governs a variety of intracellular signal transduction processes, including proteasome degradation, DNA damage repair, and cell cycle progression. Studies have found that ubiquitin can play a role in eye diseases such as cataracts, glaucoma, keratopathy, retinopathy, and eye tumors. In this paper, the role of protein ubiquitination in eye diseases was reviewed.

Development and psychometric evaluation of beliefs about the orthokeratology lens compliance scale (BOLCS): Based on the theory of planned behavior. Cont Lens Anterior Eye 2024:102186. [PMID: 38782621 DOI: 10.1016/j.clae.2024.102186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 05/07/2024] [Accepted: 05/11/2024] [Indexed: 05/25/2024]
Abstract
PURPOSE Non-adherence to standard wear, care, and follow-up procedures is a major risk factor for contact lens-related complications. The effectiveness of orthokeratology largely depends on the wearer's adherence. However, a deficiency in scales capturing adherence beliefs pertinent to orthokeratology exacerbates the lack of guidance for effective intervention strategies. The purpose of this study is to develop and evaluate the psychometric properties of a new scale based on the Theory of Planned Behavior that assesses the level of adherence among ortho-k wearers. METHODS This study involved three stages following the STROBE checklist: (1) developing initial scale items based on the Theory of Planned Behavior, a literature review, and a qualitative study; (2) evaluation of content and face validity; (3) psychometric testing on 296 participants. Item analysis, based on Classical Test Theory, assessed the overall consistency, reliability, and validity of the scale. RESULTS The final 37-item Beliefs about the Orthokeratology Lens Compliance Scale (BOLCS) comprises 11 dimensions. The Cronbach's alpha coefficients for each dimension ranged from 0.560 to 0.798. The folded half reliabilities were 0.845, and the combined reliabilities ranged from 0.676 to 0.793, indicating strong reliability. Item-level CVI (I-CVI) and scale-level CVI/average (S-CVI/Ave) values, assessed by the panel, ranged from 0.71 to 1 and 0.954, respectively. Exploratory and confirmatory factor analyses supported a factor structure consistent with the theoretical model. CONCLUSIONS The scale's construction adhered to a standardized process, yielding preliminary validation results with satisfactory reliability and validity.

Int Immunopharmacol 2024; 130:111749. [PMID: 38430804 DOI: 10.1016/j.intimp.2024.111749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 02/15/2024] [Accepted: 02/21/2024] [Indexed: 03/05/2024]
Abstract
AIMS Saikosaponin F (SsF) is one of the major active ingredients of Radix Bupleuri, an herb widely used in the treatment of depression. Studies have shown that dry eye disease often occurs together with depression. The aim of this study is to investigate whether SsF can improve depression-associated dry eye disease and explore the underlying mechanism. METHODS Behavioral test was used to verify the effect of SsF on CUMS-induced depression-like behaviors in mice. Corneal fluorescein staining, phenol red cotton thread test and periodic acid-Schiff (PAS) staining were used to observe the effect of SsF on depression-associated dry eye disease. Western blot (WB) was performed to observe the expression of TAK1 protein and key proteins of NF-κB and MAPK (P38) inflammatory pathways in the hippocampus and cornea. Immunohistochemical staining was used to observe the expression of microglia, and immunoprecipitation was used to observe K63-linked TAK1 ubiquitination. Subsequently, we constructed a viral vector sh-TAK1 to silence TAK1 protein to verify whether SsF exerted its therapeutic effect based on TAK1. The expression of inflammatory factors such as IL-1β, TNF-α and IL-18 in hippocampus and cornea were detected by ELISA. Overexpression of TRIM8 (OE-TRIM8) by viral vector was used to verify whether SsF improved depression-associated dry eye disease based on TRIM8. RESULTS SsF treatment significantly improved the depression-like behavior, increased tear production and restored corneal injury in depression-related dry eye model mice. SsF treatment downregulated TAK1 expression and TRIM8-induced K63-linked TAK1 polyubiquitination, while inhibiting the activation of NF-κB and MAPK (P38) inflammatory pathways and microglial expression. In addition, selective inhibition of TAK1 expression ameliorated depression-associated dry eye disease, while overexpression of TRIM8 attenuated the therapeutic effect of SsF on depression-associated dry eye disease. CONCLUSION SsF inhibited the polyubiquitination of TAK1 by acting on TRIM8, resulting in the downregulation of TAK1 expression, inhibition of inflammatory response, and improvement of CUMS-induced depression-associated dry eye disease.

Abstract
Tripartite motif (TRIM)-containing proteins, one of the largest subfamilies of the RING type E3 ubiquitin ligases, control important biological processes such as cell apoptosis, autophagy, signal transduction, innate immunity and tumorigenesis. So far, the mutual regulation between TRIM family members has rarely been reported. Here, we found for the first time that there was a direct mutual regulation between TRIM21 and TRIM8 in lung and renal cancer cells, mechanistically by activating their proteasome pathway via Lys48 (K48)- linked ubiquitination. Subsequent studies verified that negatively correlated expressions existed in clinical non-small cell lung cancer (NSCLC) and renal cell carcinoma (RCC) tissues, which were closely related to tumor progression. Our findings highlighted a possible homeostasis between TRIM21 and TRIM8 that might possibly affect cell stemness and was expected to provide a new idea for cancer therapy.

Abstract
Bacterial infections represent an unsolved problem today since bacteria can evade antibiotics and suppress the host's immune response. A family of TRIM proteins is known to play a role in antiviral defense. However, the data on the involvement of the corresponding genes in the antibacterial response are limited. Here, we used RT-qPCR to profile the transcript levels of TRIM genes, as well as interferons and inflammatory genes, in human cell lines (in vitro) and in mice (in vivo) after bacterial infections caused by Pseudomonas aeruginosa and Chlamydia spp. As a result, the genes were identified that are involved in the overall immune response and associated primarily with inflammation in human cells and in mouse organs when infected with both pathogens (TRIM7, 8, 14, 16, 17, 18, 19, 20, 21, 47, 68). TRIMs specific to the infection (TRIM59 for P. aeruginosa, TRIM67 for Chlamydia spp.) were revealed. Our findings can serve as a basis for further, more detailed studies on the mechanisms of the immune response to P. aeruginosa and Chlamydia spp. Studying the interaction between bacterial pathogens and the immune system contributes to the search for new ways to successfully fight bacterial infections.

Abstract
Background Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease that was caused by the Dabie bandavirus (DBV), and it has become a global public health threat. Cytokine storm is considered to be an important pathogenesis of critical SFTS. Tripartite motif-containing 3 (TRIM3), as a member of the TRIM protein family, may contribute to the regulation of the immune and inflammatory responses after viral infection. However, whether TRIM3 plays a major role in the pathogenesis of SFTS has not yet been investigated. Methods TRIM3 mRNA levels were detected in PBMCs between 29 SFTS patients and 29 healthy controls by qRT-PCR. We established the pathogenic IFNAR-/- SFTS mouse model successfully by inoculating subcutaneously with DBV and testing the expression levels of TRIM3 mRNA and protein by qRT-PCR and immunofluorescence in the livers, spleens, lungs, and kidneys. TRIM3OE THP-1 cells and peritoneal macrophages extracted from TRIM3-/- mice were infected with DBV. The effect of TRIM3 on cytokines was detected by qRT-PCR and ELISA. Then we examined Toll-like receptor 3 (TLR3) and protein phosphorylation in the MAPK pathway after DBV infection using Western blot. Flow cytometry was used to verify TLR3 expression on peripheral blood monocytes in SFTS patients. We further explored the interaction between TRIM3 and TLR3 using CO-IP and Western blot. Results Compared to healthy controls, TRIM3 mRNA expression in PBMCs is decreased in SFTS patients, especially in severe cases. TRIM3 mRNA and protein were synchronously reduced in the livers, spleens, lungs, and kidney tissues of the IFNAR-/- SFTS mice model. In the DBV-infected cell model, TRIM3 overexpression can inhibit the DBV-induced release of IL-1β, IL-6, and TNF-α, the expression of TLR3, and protein phosphorylation in the MAPK pathway, which plays an anti-inflammatory role, while TRIM3 deficiency exacerbates the pro-inflammatory effects. We further found that TRIM3 can promote TLR3 degradation through K48-linked ubiquitination. Conclusion TRIM3 can inhibit the production of cytokines by regulating the degradation of TLR3 through K48-linked ubiquitination, which can be a therapeutic target for improving the prognosis of SFTS.

Abstract
Infectious keratitis is a vision-threatening microbial infection. The increasing antimicrobial resistance and the fact that severe cases often evolve into corneal perforation necessitate the development of alternative therapeutics for effective medical management. Genipin, a natural crosslinker, was recently shown to exert antimicrobial effects in an ex vivo model of microbial keratitis, highlighting its potential to serve as a novel treatment for infectious keratitis. This study aimed to evaluate the antimicrobial and anti-inflammatory effects of genipin in an in vivo model of Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa) keratitis. Clinical scores, confocal microscopy, plate count, and histology were carried out to evaluate the severity of keratitis. To assess the effect of genipin on inflammation, the gene expression of pro- and anti-inflammatory factors, including matrix metalloproteinases (MMPs), were evaluated. Genipin treatment alleviated the severity of bacterial keratitis by reducing bacterial load and repressing neutrophil infiltration. The expression of interleukin 1B (IL1B), interleukin 6 (IL6), interleukin 8 (IL8), interleukin 15 (IL15), tumor necrosis factor-α (TNF-α), and interferon γ (IFNγ), as well as MMP2 and MMP9, were significantly reduced in genipin-treated corneas. Genipin promoted corneal proteolysis and host resistance to S. aureus and P. aeruginosa infection by suppressing inflammatory cell infiltration, regulating inflammatory mediators, and downregulating the expression of MMP2 and MMP9.

Dissecting the Functional Role of the TRIM8 Protein on Cancer Pathogenesis. Cancers (Basel) 2022; 14:cancers14092309. [PMID: 35565438 PMCID: PMC9099786 DOI: 10.3390/cancers14092309] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 04/28/2022] [Accepted: 04/30/2022] [Indexed: 02/07/2023] Open
Abstract
Simple Summary The tripartite motif (TRIM) gene family is a large group of E3 ubiquitin ligase proteins that can also have proteasome-independent functions. This review summarizes the structural organization, the biological functions and the mechanisms involved in cancer pathogenesis of TRIM proteins. Furthermore, this paper focuses on TRIM8, a member of the TRIM family proteins, describing its role both as a tumor suppressor and as an oncogene. Abstract TRIM/RBCC are a large family of proteins that include more than 80 proteins, most of which act as E3 ligases and catalyze the direct transfer of Ubiquitin, SUMO and ISG15 on specific protein substrates. They are involved in oncogenesis processes and in cellular immunity. On this topic, we focus on TRIM8 and its multiple roles in tumor pathologies. TRIM8 inhibits breast cancer proliferation through the regulation of estrogen signaling. TRIM8 downregulation in glioma is involved in cell proliferation, and it is related to patients’ survival. Several studies suggested that TRIM8 regulates the p53 suppressor signaling pathway: it is involved in the NF-kB pathway (Nuclear Factor kappa light- chain-enhancer of activated B cells) and in STAT3 (Signal Transducer and Activator of Transcription 3) of the JAK-STAT pathway. In this review, we summarize how the association between these different pathways reflects a dual role of TRIM8 in cancer as an oncogene or a tumor suppressor gene.

Abstract
Pseudomonas aeruginosa (PA)‑induced keratitis is characterized by inflammatory epithelial edema, stromal infiltration, corneal ulceration and can lead to vision loss. The present study aimed to study the effect of ubiquitin‑specific protease 22 (USP22) on PA‑induced keratitis. Using RT‑qPCR and western blotting, significantly increased expression of USP22 was identified in mouse corneas and cultured RAW264.7 cells following PA stimulation. In addition, the results of in vivo experiments, western blot assay and ELISA suggested that the silencing of USP22 attenuated disease progression, downregulated the NF‑κB pathway and suppressed the expression of pro‑inflammatory cytokines following PA stimulation. Notably, it was identified that the expression of tumor necrosis factor receptor‑associated factor 6 (TRAF6) was decreased by silencing of USP22 and USP22 was found to remove lysine 48‑linked poly‑ubiquitination chains from TRAF6 to stabilize TRAF6 expression and these effects were clearly aggravated following PA infection.

Drug Des Devel Ther 2021; 15:4973-4983.

Abstract
Background Acute kidney injury (AKI) emerges as an acute and critical disease. Tripartite motif 8 (TRIM8), one number of the TRIM protein family, is proved to participate in ischemia/reperfusion (I/R) injury. However, whether TRIM8 is involved in renal I/R injury and the associated mechanisms are currently unclear. Purpose This study aimed to investigate the precise role of TRIM8 and relevant mechanisms in renal I/R injury. Materials and Methods In this study, human renal proximal tubular epithelial cells (HK-2 cells) underwent 12 hours of hypoxia and 2 h, 3 h or 4 h of reoxygenation to establish an in vitro hypoxia/reoxygenation (H/R) model. The siRNAs specific to TRIM8 (si-TRIM8) were transfected into HK-2 cells to knockdown TRIM8. The cell H/R model included various groups including Control, H/R, H/R+DMSO, H/R+NAC, si-NC+H/R, si-TRIM8+H/R and si-TRIM8+LY294002+H/R. The cell viability and levels of reactive oxygen species (ROS), hydrogen peroxide (H2O2), mRNA, apoptotic proteins, pyroptosis-related proteins and PI3K/AKT pathway-associated proteins were assessed. Results In vitro, realtime-quantitative PCR and western-blot analysis showed that the mRNA and protein expression of TRIM8 were obviously upregulated after H/R treatment in HK-2 cells. Compared with the H/R model group, knockdown of TRIM8 significantly increased cell viability and reduced the levels of ROS, H2O2, apoptotic proteins (Cleaved caspasebase-3 and BAX) and pyroptosis-related proteins (NLRP3, ASC, Caspase-1, Caspase-11, IL-1β and GSDMD-N). Western-blot analysis also authenticated that PI3K/AKT pathway was activated after TRIM8 inhibition. The application of 5 mM N-acetyl-cysteine, one highly efficient ROS inhibitor, significantly suppressed the expression of apoptotic proteins and pyroptosis-related proteins. Moreover, the combined treatment of TRIM8 knockdown and LY294002 reversed the effects of inhibiting oxidative stress. Conclusion Knockdown of TRIM8 can alleviate H/R-induced oxidative stress by triggering the PI3K/AKT pathway, thus attenuating pyropyosis and apoptosis in vitro.

Abstract
Osteoarthritis (OA) is a degenerative joint disease associated with inflammatory response. Tripartite motif 8 (TRIM8) is a member of TRIM family that has been found to regulate inflammation. The present study was aimed to evaluate the role of TRIM8 in OA chondrocytes. Our results showed that TRIM8 expression was significantly increased in interleukin 1 beta (IL-1β)-stimulated OA chondrocytes. To knock down the TRIM8 expression in chondrocytes, the chondrocytes were transfected with si-TRIM8. Knockdown of TRIM8 attenuated IL-1β-induced production of inflammatory mediators including nitric oxide and prostaglandin E2. The increased expression levels of inducible nitric oxide synthase and cyclooxygenase-2 in IL-1β-induced chondrocytes were suppressed by TRIM8 knockdown. The IL-1β-induced production of proinflammatory cytokines including TNF-α and IL-6 was significantly decreased after transfection with si-TRIM8. Besides, knockdown of TRIM8 mitigated the IL-1β-induced decrease in aggrecan and collagen-II proteins expression and increase in matrix-degrading enzymes in chondrocytes. Furthermore, TRIM8 knockdown prevented IL-1β-induced nuclear factor kappa B (NF-κB) activation in chondrocytes. Taken together, these findings indicated that knockdown of TRIM8 attenuates IL-1β-induced inflammatory response in OA chondrocytes through the inactivation of NF-κB pathway. Thus, targeting TRIM8 might provide therapeutic treatment for OA.

Abstract
The superfamily of TRIM (TRIpartite Motif-containing) proteins is one of the largest groups of E3 ubiquitin ligases. Among them, interest in TRIM8 has greatly increased in recent years. In this review, we analyze the regulation of TRIM8 gene expression and how it is involved in many cell reactions in response to different stimuli such as genotoxic stress and attacks by viruses or bacteria, playing a central role in the immune response and orchestrating various fundamental biological processes such as cell survival, carcinogenesis, autophagy, apoptosis, differentiation and inflammation. Moreover, we show how TRIM8 functions are not limited to ubiquitination, and contrasting data highlight its role either as an oncogene or as a tumor suppressor gene, acting as a “double-edged weapon”. This is linked to its involvement in the selective regulation of three pivotal cellular signaling pathways: the p53 tumor suppressor, NF-κB and JAK-STAT pathways. Lastly, we describe how TRIM8 dysfunctions are linked to inflammatory processes, autoimmune disorders, rare developmental and cardiovascular diseases, ischemia, intellectual disability and cancer.

Abstract
The tripartite motif (TRIM) family comprises at least 80 members in humans, with most having ubiquitin or SUMO E3 ligase activity conferred by their N-terminal RING domain. TRIMs regulate a wide range of processes in ubiquitination- or sumoylation-dependent manners in most cases, and fewer as adaptors. Their roles in the regulation of viral infections, autophagy, cell cycle progression, DNA damage and other stress responses, and carcinogenesis are being increasingly appreciated, and their E3 ligase activities are attractive targets for developing specific immunotherapeutic strategies for immune diseases and cancers. Given their importance in antiviral immune response, viruses have evolved sophisticated immune escape strategies to subvert TRIM-mediated mechanisms. In this review, we focus on their regulation of IFN-I-mediated innate immune response, which plays key roles in antiviral and antitumor defense.

[PMID: 33129786 DOI: 10.1016/j.yexmp.2020.104562] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 08/02/2020] [Accepted: 10/25/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND The long noncoding RNAs (lncRNAs) have been confirmed to be involved in sepsis-induced organ injury. Here, we first investigated the functional role and the underlying mechanism of lncRNA LINC00472 in sepsis-induced acute hepatic injury (AHI). METHODS Human liver THLE-3 cells were treated with lipopolysaccharide (LPS) to mimic sepsis-induced AHI in vitro; intraperitoneal injection of LPS in rats were used as an in vivo model of AHI induced by sepsis. The expressions of LINC00472, miR-373-3p, and TRIM8 mRNA were detected by qRT-PCR. The effects of LINC00472 and miR-373-3p on the viability of THLE-3 cells were assessed by CCK-8 assay. Dual-luciferase reporter and RNA immunoprecipitation (RIP) assays were performed to determine the binding relationship between LINC00472 and miR-373-3p as well as between miR-373-3p and TRIM8. The expressions of apoptosis-related proteins and TRIM8 were detected by Western blot; the levels of ALT, AST, TNF-α, IL-6, and IL-10 in the serum of rats were measured using ELSA assay. RESULTS LINC00472 and TRIM8 were significantly upregulated in liver tissues and THLE-3 cells in sepsis-induced AHI models, while miR-373-3p was downregulated. Silencing of LINC00472 promoted cell viability and suppressed cell apoptosis in LPS-treated THLE-3 cells, whereas upregulation of LINC00472 had the opposite effect. Moreover, LINC00472 served as a sponge for miR-373-3p and negatively regulated its expression. miR-373-3p mimics could promote THLE-3 cell viability and suppress cell apoptosis. Additionally, TRIM8 was a direct target of miR-373-3p, which was downregulated in LINC00472-silenced cells and upregulated by the miR-373-3p inhibitor. Further, the co-transfection of miR-373-3p inhibitor reversed the effects of LINC00472 knockdown on cell viability and apoptosis. Downregulation of LINC00472 in rats restored the levels of ALT, AST, IL-6, IL-10, and TNF-α. CONCLUSION Downregulation of LINC00472 ameliorates sepsis-induced AHI by regulating the miR-373-3p/TRIM8 axis.

Abstract
The human tripartite motif containing protein 8 (TRIM8), a member of TRIM family proteins, is known to play a dual role as both tumor suppressor and oncogene, and to function at the crosstalk of cancer and innate immunity. In this review, in addition to accumulating recent corroborations that endorse this dual character of TRIM8, we appraise the game-changing capacity of TRIM8 under stress conditions against the backdrop of cell proliferation, apoptosis, and cancer, and also highlight the duality of TRIM8 in multiple contexts like cellular localization, stress-induced conditions, and E3 ubiquitin ligase activity. Finally, we discuss the emerging role of TRIM8 during bipolar spindle formation and mitotic progression, and its growing sphere of influence across multiple human cancers and pathologies, and suggest TRIM8-linked axes that can be modulated further for anti-cancer therapeutics development.

Abstract
Microglial inflammation induced by ischemic stroke aggravates brain damage. MicroRNAs (miRNAs) have emerged as pivotal regulators in ischemic stroke-induced inflammation in microglial cells. miR-665-3p has been reported as a critical inflammation-associated miRNA. However, whether miR-665-3p participates in regulating microglial inflammation during ischemic stroke is underdetermined. This study investigated the potential role of miR-665-3p in stroke-induced inflammation in microglial cells using a cellular model of oxygen-glucose deprivation (OGD)-stimulated microglial cells in vitro. We found that miR-665-3p expression was decreased in microglial cells exposed to OGD treatment. Functional experiments demonstrated that the overexpression of miR-665-3p attenuated OGD-induced apoptosis and inflammation in microglial cells. Notably, tripartite motif 8 (TRIM8) was identified as a target gene of miR-665-3p. TRIM8 expression was induced by OGD treatment in microglial cells and the knockdown of TRIM8 protected microglial cells from OGD -induced cytotoxicity and inflammation. Moreover, TRIM8 knockdown or miR-665-3p overexpression blocked OGD-induced activation of nuclear factor (NF)-κB signaling in microglial cells. In addition, TRIM8 overexpression partially reversed the miR-665-3p overexpression-mediated inhibitory effect on OGD-induced inflammation in microglial cells. Taken together, these results indicate that miR-665-3p up-regulation protects microglial cells from OGD-induced apoptosis and inflammatory response by targeting TRIM8 to inhibit NF-κB signaling.

Abstract
MicroRNAs (miRNAs) have emerged as critical modulators involved in the regulation of airway remodeling in asthma. MicroRNA-182-5p (miR-182-5p) has been reported as a key miRNA in regulating the proliferation and migration of various cell types, and its dysfunction contributes is implicated in a wide range of pathological processes. Yet, it remains unknown whether miR-182-5p modulates the proliferation and migration of airway smooth muscle (ASM) cells during asthma. In the present study, we aimed to determine the potential role of miR-182-5p in regulating the proliferation and migration of ASM cells induced by tumor necrosis factor (TNF)-α in vitro. We found that TNF-α stimulation markedly reduced miR-182-5p expression in ASM cells. Gain-of-function experiments showed that miR-182-5p upregulation suppressed the proliferation and migration of ASM cells induced by TNF-α. By contrast, miR-182-5p inhibition had the opposite effect. Notably, tripartite motif 8 (TRIM8) was identified as a target gene of miR-182-5p. TRIM8 expression was induced by TNF-α stimulation, and TRIM8 knockdown markedly impeded TNF-α-induced ASM cell proliferation and migration. Moreover, miR-182-5p overexpression or TRIM8 knockdown significantly downregulated the activation of nuclear factor-κB (NF-κB) induced by TNF-α. However, TRIM8 restoration partially reversed the miR-182-5p-mediated inhibitory effect on TNF-α-induced ASM cell proliferation and migration. In conclusion, our study indicates that miR-182-5p restricts TNF-α-induced ASM cell proliferation and migration through downregulation of NF-κB activation via targeting TRIM8. The results of our study highlight the potential importance of the miR-182-5p/TRIM8/NF-κB axis in the airway remodeling of asthma.

Abstract
Stroke is a leading global cause of mortality and disability. However, the pathogenesis that contributes to stroke has not been fully understood. The tripartite motif (TRIM)-containing proteins usually exhibit essential regulatory roles during various biological processes. TRIM8 is a RING domain-containing E3 ubiquitin ligase, playing crucial roles in regulating inflammation and apoptosis. In the present study, we reported that TRIM8 expression was significantly induced in the peri-infarct cortex area of mice after stroke onset. TRIM8 siRNA in vivo transfection resulted in the attenuated cognitive impairments in mice with cerebral ischaemia-reperfusion (IR) injury. In addition, TRIM8 knockdown was neuroprotective, as evidenced by the reduced infarct area, decreased neurological deficit score and down-regulated number of TUNEL-positive cells in the peri-infarct area. Moreover, TRIM8 inhibition obviously repressed glial fibrillary acidic protein (GFAP) expression in peri-hematoma cortex and hippocampus. Furthermore, inflammation induced by cerebral IR injury was highly restrained by TRIM8 knockdown in serum, peri-infarct area and hippocampus, which were along with the remarkable decreases in the phosphorylated expression of IκB kinase alpha (IKKα), inhibitory κB α (IκBα) and nuclear factor kappa B (NF-κB). Moreover, TRIM8 knockdown significantly reduced apoptosis in hippocampus of mice with cerebral IR injury by reducing Caspase-3 cleavage. The in vitro experiment confirmed the neuroprotective role of TRIM8-knockdown in regulating cerebral IR injury. Intriguingly, we found that TRIM8 over-expression-promoted inflammatory response and apoptosis could be markedly attenuated by the inactivation of NF-κB signaling through pre-treatment of JSH-23 or QNZ in lipopolysaccharide (LPS)-incubated astrocytes (ASTs). Therefore, TRIM8 positively regulated cerebral IR injury by activating NF-κB pathway to enhance inflammation and apoptosis. Targeting TRIM8 could provide feasible therapeutic treatment for stroke.

Abstract
The tripartite motif (TRIM) proteins have been intensively studied as essential modulators in various biological processes, especially in regulating a wide range of signaling pathways involved in immune responses. Most TRIM proteins have E3 ubiquitin ligase activity, mediating polyubiquitination of target proteins. Emerging evidence demonstrates that TRIM proteins play important roles in innate immunity by regulating pattern recognition receptors, vital adaptor proteins, kinases, and transcription factors in innate immune signaling pathways. Additionally, the critical roles of TRIM proteins in adaptive immunity, especially in T cell development and activation, are increasingly appreciated. In this review, we aim to summarize the studies on TRIMs in both innate and adaptive immunity, focusing on their E3 ubiquitin ligase functions in pattern recognition receptor signaling pathways and T cell functions, shedding light on the developing new strategies for modulating innate and adaptive immune responses against invading pathogens and avoiding autoimmunity.

Abstract
Background and Purpose- Ischemic stroke is one of the leading causes of morbidity and mortality worldwide and a major cause of long-term disability. Recently, long noncoding RNAs have been revealed, which are tightly associated with several human diseases. However, the functions of long noncoding RNAs in ischemic stroke still remain largely unknown. In the current study, for the first time, we investigated the role of long noncoding RNA Nespas in ischemic stroke. Methods- We used in vivo models of middle cerebral artery occlusion and in vitro models of oxygen-glucose deprivation to illustrate the effect of long noncoding RNA Nespas on ischemic stroke. Results- We found expression of Nespas was significantly increased in ischemic cerebral tissues and oxygen-glucose deprivation-treated BV2 cells in a time-dependent manner. Silencing of Nespas aggravated middle cerebral artery occlusion operation-induced IR injury and cell death. In addition, proinflammatory cytokine production and NF-κB (nuclear factor-κB) signaling activation were inhibited by Nespas overexpression. TAK1 (transforming growth factor-β-activated kinase 1) was found to directly interact with Nespas, and TAK1 activation was significantly suppressed by Nespas. At last, we found Nespas-inhibited TRIM8 (tripartite motif 8)-induced K63-linked polyubiquitination of TAK1. Conclusions- We showed that Nespas played anti-inflammatory and antiapoptotic roles in cultured microglial cells after oxygen-glucose deprivation stimulation and in mice after ischemic stroke by inhibiting TRIM8-related K63-linked polyubiquitination of TAK1.

Int J Biol Sci 2019; 15:1618-1629.

Abstract
Tripartite motif (Trim) 8 is an E3 ubiquitin ligase, interacting with and ubiquitinating diverse substrates, and is closely involved in innate immunity. However, the function of Trim8 in hepatic ischaemia/reperfusion (I/R) injury remains largely unknown. The aim of this study is to explore the role of Trim8 in hepatic I/R injury. Trim8 gene knockout mice and primary hepatocytes were used to construct hepatic I/R models. The effect of Trim8 on hepatic I/R injury was analysed via pathological and molecular analyses. The results indicated that Trim8 was significantly upregulated in liver of mice subjected to hepatic I/R injury. Trim8 knockout relieved hepatocyte injury triggered by I/R. Silencing of Trim8 expression alleviated hepatic inflammation responses and inhibited apoptosis in vitro and in vivo. Mechanistically, our study suggests that Trim8 deficiency may elicit hepatic protective effects by inhibiting the activation of transforming growth factor β-activated kinase 1 (TAK1)-p38/JNK signalling pathways. TAK1 was required for Trim8 function in hepatic I/R injury as TAK1 activation abolished Trim8 function in vitro. In conclusion, our study demonstrates that Trim8 deficiency plays a protective role in hepatic I/R injury by inhibiting the activation of TAK1-dependent signalling pathways.

Abstract
De novo mutations of the TRIM8 gene, which codes for a tripartite motif protein, have been identified using whole exome sequencing (WES) in two patients with epileptic encephalopathy (EE), but these reports were not sufficient to conclude that TRIM8 was a novel gene responsible for EE. Here we report four additional patients presenting with EE and de novo truncating mutations of TRIM8 detected by WES, and give further details of the patient previously reported by the Epi4K consortium. Epilepsy of variable severity was diagnosed in children aged 2 months to 3.5 years of age. All patients had developmental delay of variable severity with no or very limited language, often associated with behavioral anomalies and unspecific facial features or MRI brain abnormalities. The phenotypic variability observed in these patients appeared related to the severity of the epilepsy. One patient presented pharmacoresistant EE with regression, recurrent infections and nephrotic syndrome, compatible with the brain and kidney expression of TRIM8. Interestingly, all mutations were located at the highly conserved C-terminus section of TRIM8. This collaborative study confirms that TRIM8 is a novel gene responsible for EE, possibly associated with nephrotic syndrome. This report brings new evidence on the pathogenicity of TRIM8 mutations and highlights the value of data-sharing to delineate the phenotypic characteristics and biological basis of extremely rare disorders.

Abstract
Intermittent hypoxia/reoxygenation (IHR), characterized by repeated episodes of hypoxia interspersed with periods of reoxygenation, has been found to induce pro‑inflammatory cytokine production and is increasingly recognized as a major pathophysiological factor in various disease processes with distinct cell and molecular responses. The present study is the first, to the best of our knowledge, to investigate the effects of ubiquitin‑specific peptidase 8 (USP8) on IHR‑induced inflammation in renal tubular epithelial cells and examine the underlying mechanism. Following transfection of plasmids, HK‑2 and TCMK‑1 cells were incubated for eight cycles of IHR treatment including 3 h of hypoxic incubation followed by 3 h of normoxic culture. It was demonstrated that the expression of USP8 was decreased in IHR conditions but not in normoxic or continuous hypoxic conditions. In addition, IHR‑induced inflammation was suppressed in USP8‑overexpressinh renal tubular epithelial cells, and the silencing of USP8 markedly aggravated inflammation. Furthermore, it was found that the overexpression of USP8 inhibited the IHR‑induced activation of nuclear factor‑κB and it was demonstrated that USP8 interacted with transforming growth factor‑β‑activated kinase‑1 (TAK1) and deubiquitinated the K63‑linked ubiquitination of TAK1. Taken together, the results demonstrated the role of USP8 in IHR‑induced inflammation and suggested USP8 as a potential and specific therapeutic target for IHR‑related diseases.
