Long J, Zhao W, Xiang Y, Wang Y, Xiang W, Liu X, Jiang M, Song Y, Hu J. STAT3 promotes cytoplasmic-nuclear translocation of RNA-binding protein HuR to inhibit IL-1β-induced IL-8 production. Int Immunopharmacol 2024; 133:112065. [PMID: 38608448 DOI: 10.1016/j.intimp.2024.112065] [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: 11/25/2023] [Revised: 04/08/2024] [Accepted: 04/08/2024] [Indexed: 04/14/2024]
Abstract
Signal transducer and activator of transcription 3 (STAT3) functions to regulate inflammation and immune response, but its mechanism is not fully understood. We report here that STAT3 inhibitors Stattic and Niclosamide up-regulated IL-1β-induced IL-8 production in C33A, CaSki, and Siha cervical cancer cells. As expected, IL-1β-induced IL-8 production was also up-regulated through the molecular inhibition of STAT3 by use of CRISPR/Cas9 technology. Unexpectedly, IL-1β induced IL-8 production via activating ERK and P38 signal pathways, but neither STAT3 inhibitors nor STAT3 knockout affected IL-1β-induced signal transduction, suggesting that STAT3 decreases IL-8 production not via inhibition of signal transduction. To our surprise, STAT3 inhibition increased the stabilization, and decreased the degradation of IL-8 mRNA, suggesting a post-transcriptional regulation of IL-1β-induced IL-8. Moreover, Dihydrotanshinone I, an inhibitor of RNA-binding protein HuR, down-regulated IL-1β-induced IL-8 dose-dependently. HuR inhibition by CRISPR/Cas9 also decreased IL-8 production induced by IL-1β. Mechanistically, co-immunoprecipitation results showed that STAT3 did not react with HuR directly, but STAT3 inhibition increased the protein levels of HuR in cytoplasm. And IL-6 activation of STAT3 induced HuR cytoplasmic-nuclear transport. Taken together, these results suggest that STAT3 contributes to HuR nuclear localization and inhibits Il-1β-induced IL-8 production through this non-transcriptional mechanism.

[PMID: 37760252 PMCID: PMC10526110 DOI: 10.3390/ani13182853] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 09/03/2023] [Accepted: 09/06/2023] [Indexed: 09/29/2023] Open
Abstract
Midline2 (MID2/TRIM1) is a member of the tripartite motif-containing (TRIM) family, which is involved in a wide range of cellular processes. However, fundamental studies on porcine MID2 (pMID2) are still lacking. In this study, we identified and characterized the full length MID2 gene of pig (Sus scrofa). The sequence alignment analysis results showed that pMID2 had an N-terminal RING zinc-finger domain, BBC domain, and C-terminal COS box, FN3 motif, and PRY-SPRY domain that were conserved and similar to those of other vertebrates. Furthermore, pMID2 had the highest expression levels in porcine lung and spleen. Serial deletion and site-directed mutagenesis showed that the putative nuclear factor-κB (NF-κB) binding site may be an essential transcription factor for regulating the transcription expression of pMID2. Furthermore, the immunofluorescence assay indicated that pMID2 presented in the cell membrane and cytoplasm. To further study the functions of pMID2, we identified and determined its potential ability to perceive poly (I:C) and IFN-α stimulation. Stimulation experiments showed pMID2 enhanced poly (I:C)-/IFN-α-induced JAK-STAT signaling pathway, indicating that pMID2 might participate in the immune responses. In conclusion, we systematically and comprehensively analyzed the characterizations and functions of pMID2, which provide valuable information to explore the pMID2 functions in innate immunity. Our findings not only enrich the current knowledge of MID2 in IFN signaling regulation but also offer the basis for future research of pig MID2 gene.

Abstract
Osteoarthritis (OA) is a multifactorial chronic disease primarily characterized by the degeneration of articular cartilage. Currently, there is a lack of effective treatments for OA other than surgery. The exploration of the mechanisms of occurrence is important in exploring other new and effective treatments for OA. The current evidence shows that the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway plays a vital role in cytogenesis and is involved in OA progression. The terms "JAK2", "STAT3", and "Osteoarthritis"were used in a comprehensive literature search in PubMed to further investigate the relationship between the JAK2/STAT3 signaling pathway and OA. This review focuses on the role and mechanism of JAK2/STAT3 signaling in cartilage degradation, subchondral bone dysfunction, and synovial inflammation. In addition, this review summarizes recent evidence of therapeutic approaches to treat OA by targeting the JAK2/STAT3 pathway to accelerate the translation of evidence into the progression of strategies for OA treatment.

Abstract
The tripartite motif (TRIM) proteins play critical roles in viral infection by modulating innate immunity. However, the molecular and antiviral activity of TRIM59 in mandrain fish is not fully understood. In present study, we cloned and sequenced the TRIM59 core sequence and explored its characteristics in Mandarin fish. The Siniperca chuatsi TRIM59 (scTRIM59) showed relatively high expression in immune-related organs. scTRIM59 expression was significantly down-regulated post ISKNV infection in vivo and vitro, but up-regulated at the early stages of SCRV infection in CPB cells. The overexpression of scTRIM59 inhibited ISKNV and SCRV infection, but decreased the expression of IRF3/IRF7-mediated signal genes. However, knockdown of scTRIM59 promoted the ISKNV and SCRV infection, but increased the expression of IRF3/IRF7-mediated signal genes. Those results indicated that scTRIM59 negatively regulated ISKNV, SCRV infection and IRF3/IRF7-mediated signal genes. This study provided new ideas about the function of scTRIM59.

LncRNA BANCR Promotes Endometrial Stromal Cell Proliferation and Invasion in Endometriosis via the miR-15a-5p/TRIM59 Axis. Int J Genomics 2022; 2022:9083822.

Abstract
Long non-coding RNA (LncRNA) emerges as a regulator in various diseases, including endometriosis (EM). This study aims to uncover the role of long non-coding RNA BRAF-activated non-protein coding RNA (lncRNA BANCR)-mediated competing endogenous RNA mechanism in endometrial stromal cell (ESC) proliferation and invasion in EM by regulating miR-15a-5p/TRIM59. ESCs were isolated from eutopic and ectopic endometrial tissues, followed by the determination of Cytokeratin 19 and Vimentin expressions in cells. Then, expressions of lncRNA BANCR, microRNA (miR)-15a-5p, and tripartite motif-containing 59 (TRIM59) in tissues and cells were determined by real-time quantitative polymerase chain reaction or Western blot assay, and cell proliferation and invasion were evaluated by cell counting kit-8 and transwell assays. After that, the subcellular localization of lncRNA BANCR and binding of miR-15a-5p to lncRNA BANCR or TRIM59 were analyzed. LncRNA BANCR was upregulated in ectopic endometrial tissues and ectopic ESCs (Ect-ESCs). Silencing lncRNA BANCR suppressed Ect-ESC proliferation and invasion. LncRNA BANCR inhibited miR-15a-5p to promote TRIM59 expression. miR-15a-5p downregulation or TRIM59 overexpression both reversed the effects of silencing lncRNA BANCR on Ect-ESC proliferation and invasion. In summary, our findings suggested that lncRNA BANCR facilitated Ect-ESC proliferation and invasion by inhibiting miR-15a-5p and promoting TRIM59.

Abstract
TRIM59 is a member of the tripartite motif containing (TRIM) protein family. It functions as an E3 ubiquitin ligase through its RING domain and is expressed by multiple types of cells. Physiogically, TRIM59 is involved in development, immune response, and the invasion and metastasis of tumors. In this review, we first describe the structure, expression, and subcellular location of TRIM59. Then, we summarize emerging evidence for TRIM59 in immunological diseases including infection, vascular diseases, autoimmunity, and tumor immunity. Additionally, we discuss important molecular signaling pathways that mediate TRIM59 activity. Altogether, the accumulating evidence suggests that manipulating TRIM59 levels and activity may open an avenue for innovative therapies for immune diseases and tumors.

Abstract
Tripartite motif-containing proteins (TRIMs), exhibiting ubiquitin E3 ligase activity, are involved in regulation of not only autophagy and apoptosis but also pyrotosis and antiviral immune responses of host cells. TRIMs play important roles in modulating signaling pathways of antiviral immune responses via type I interferon, NF-κB, Janus kinase/signal transducer and activator of transcription (JAK/STAT), and Nrf2. However, viruses are able to antagonize TRIM activity or evenly utilize TRIMs for viral replication. This communication presents the current understanding of TRIMs exploited by viruses to evade host immune response.

Abstract
Increasing evidence indicates that long non-coding RNAs (lncRNAs) play critical roles in osteoarthritis (OA). The present study aimed to investigate the underlying molecular mechanism of lncRNA musculin antisense RNA 1 (MSC-AS1) in OA. RT-qPCR was used to detect MSC-AS1 levels in cartilage tissues from patients with OA. The effects of MSC-AS1 knockdown on the viability and apoptosis in OA were evaluated via CCK-8 and TUNEL assays. The StarBase database was used to predict the binding sites between microRNA (miR)-369-3p and MSC-AS1 or JAK2, which were confirmed via the dual-luciferase reporter assay. The results demonstrated that MSC-AS1 expression was downregulated in OA. Functional analysis indicated that the addition of MSC-AS1 promoted viability and inhibited inflammation and the apoptosis of chondrocytes. In addition, MSC-AS1 regulated the survival of OA chondrocytes by sponging miR-369-3p. JAK2 was confirmed as a direct target of miR-369-3p, and MSC-AS1 regulated JAK2/STAT3 signaling via miR-369-3p in OA chondrocytes. Taken together, our results suggest that MSC-AS1 may regulate the miR-369-3p/JAK2/STAT3 signaling pathway to accelerate the viability, and inhibit inflammation and cell apoptosis in OA chondrocytes.

Abstract
The dysregulation of circular RNA (circRNA) has been monitored in osteoarthritis (OA) cartilage, hinting that circRNA deregulation modulates OA progression. We thus aimed to unveil the role of circRNA spastic paraplegia 11 (circ_SPG11) in OA conditions. The upregulation of circ_SPG11 was observed in OA cartilage and IL-1β-treated chondrocytes. Knockdown of circ_SPG11 restored IL-1β-depleted cell proliferation and alleviated IL-1β-induced cell apoptosis and ECM degradation. Circ_SPG11 bound to miR-665 and negatively regulated miR-665 expression. Inhibition of miR-665 reversed the inhibitory effect on IL-1β-induced chondrocyte injury caused by circ_SPG11 knockdown. GREM1 was a target of miR-665, and circ_SPG11 knockdown depleted GREM1 expression by enriching miR-665. Overexpression of GREM1 also reversed the inhibitory effect on IL-1β-induced chondrocyte injury caused by miR-665 enrichment. Circ_SPG11 might promote IL-1β-induced chondrocyte apoptosis and ECM degradation via increasing GREM1 expression by decoying miR-665.

Abstract
Osteosarcoma (OS) is a common, highly malignant bone tumor. Tripartite motif-containing protein 59 (TRIM59) has been identified as a potential oncogenic protein involved in the initiation and progression of various human carcinomas. Nonetheless, the possible roles and molecular mechanisms of action of TRIM59 in OS remain unclear. In this study, we found that TRIM59 expression levels were frequently upregulated in OS tissues and cell lines. TRIM59 knockdown significantly suppressed the proliferation, migration, and invasion of OS cells and promoted OS cell apoptosis, whereas TRIM59 overexpression had the opposite effects. In vivo experiments demonstrated that TRIM59 knockdown suppressed OS tumor growth and metastasis in vivo. Furthermore, we found that TRIM59 directly interacted with phospho-STAT3 in OS cells. The downregulation of STAT3 levels attenuated TRIM59-induced cell proliferation and invasion. Taken together, our results indicate that TRIM59 promoted OS progression via STAT3 activation. Therefore, our study may provide a novel therapeutic target for OS.

Abstract
Aim: To investigate whether kaempferol exhibited protective effects on osteoarthritis chondrocytes by modulating the XIST/miR-130a/STAT3 axis. Methods: qRT-PCR and western blot assays were used for gene and protein determination. Dual luciferase reporter and RNA immunoprecipitation assays were employed to study the interaction between miRNA and lncRNA or genes. Results: Kaempferol decreased proinflammatory cytokine production and extracellular matrix degradation in C28/I2 cells. Additionally, kaempferol ameliorated XIST expression and enhanced miR-130a expression. XIST interacted with miR-130a, and STAT3 was identified as a target of miR-130a. Knockdown of XIST expression suppressed proinflammatory cytokine production and extracellular matrix degradation in C28/I2 cells. Overexpression of STAT3 rescued the effects of XIST knockdown. Conclusion: Kaempferol inhibited inflammation and extracellular matrix degradation by modulating the XIST/miR-130a/STAT3 axis in chondrocytes.

Abstract
Osteoarthritis (OA) is a chronic disease characterized by progressive loss of cartilage and failure of the diarthrodial joint. Circular RNAs (circRNAs) are known to participate in the pathogenesis of multiple diseases, including OA. We investigated the functions of hsa_circ_0032131, a circRNA upregulated in OA, using CHON-001 cells and an in vivo OA rat model. CHON-001 cells were treated with interleukin (IL)-1β to mimic OA in vitro. IL-1β-induced inhibition of CHON-001 growth was reversed by silencing hsa_circ_0032131. In addition, hsa_circ_0032131 knockdown reversed IL-1β-induced activation of Trx1, Cyclin D and PRDX3, whereas overexpression of PRDX3, a direct target of miR-502-5p, reversed this effect. Hsa_circ_0032131 served as a competing endogenous RNA for miR-502-5p. Moreover, knockdown of hsa_circ_0032131 attenuated OA symptoms in vivo by inactivating the STAT3 signaling pathway. Thus, silencing of hsa_circ_0032131 inhibited the progression of OA by inactivating the miR-502-5p/PRDX3/Trx1/STAT3 axis, which highlights its potential as a therapeutic target for OA.
