Abstract
Ubiquitin-specific protease 5 (USP5) belongs to the ubiquitin-specific protease (USP) family, which uniquely recognizes unanchored polyubiquitin chains to maintain the homeostasis of monoubiquitin chains. USP5 participates in a wide range of cellular processes by specifically cleaving isopeptide bonds between ubiquitin and substrate proteins or ubiquitin itself. In the process of immune regulation, USP5 affects important cellular signaling pathways, such as NF-κB, Wnt/β-catenin, and IFN, by regulating ubiquitin-dependent protein degradation. These pathways play important roles in immune regulation and inflammatory responses. In addition, USP5 regulates the activity and function of immunomodulatory signaling pathways via the deubiquitination of key proteins, thereby affecting the activity of immune cells and the regulation of immune responses. In the present review, the structure and function of USP5, its role in immune regulation, and the mechanism by which USP5 affects the development of diseases by regulating immune signaling pathways are comprehensively overviewed. In addition, we also introduce the latest research progress of targeting USP5 in the treatment of related diseases, calling for an interdisciplinary approach to explore the therapeutic potential of targeting USP5 in immune regulation.

Jang JH, Kim H, Kim HR, Cho JH. Rainbow trout DUBA inhibits type I interferon signaling by deubiquitinating TRAF3. FISH & SHELLFISH IMMUNOLOGY 2024; 149:109581. [PMID: 38670412 DOI: 10.1016/j.fsi.2024.109581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 04/18/2024] [Accepted: 04/21/2024] [Indexed: 04/28/2024]
Abstract
Deubiquitinating enzyme A (DUBA), a member of the ovarian tumor (OTU) subfamily of deubiquitinases (DUBs), is recognized for its negative regulatory role in type I interferon (IFN) expression downstream of Toll-like receptor 3 (TLR3). However, its involvement in the TLR3 signaling pathway in fish remains largely unexplored. In this study, we investigated the regulatory role of DUBA (OmDUBA) in the TLR3 response in rainbow trout (Oncorhynchus mykiss). OmDUBA features a conserved OTU domain, and its expression increased in RTH-149 cells following stimulation with the TLR3 agonist poly(I:C). Gain- and loss-of-function experiments demonstrated that OmDUBA attenuated the activation of TANK-binding kinase 1 (TBK1), resulting in a subsequent reduction in type I IFN expression and IFN-stimulated response element (ISRE) activation in poly(I:C)-stimulated cells. OmDUBA interacted with TRAF3, a crucial mediator in TLR3-mediated type I IFN production. Under poly(I:C) stimulation, there was an augmentation in the K63-linked polyubiquitination of TRAF3, a process significantly inhibited upon OmDUBA overexpression. These findings suggest that OmDUBA may function similarly to its mammalian counterparts in downregulating the poly(I:C)-induced type I IFN response in rainbow trout by removing the K63-linked ubiquitin chain on TRAF3. Our study provides novel insights into the role of fish DUBA in antiviral immunity.

Baek EJ, Jeong YJ, Kim GH, Kim MJ, Kim KI. Effects on viral suppression and the early-immune expression of ribavirin against spring viremia of carp virus in vitro. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2024; 154:105145. [PMID: 38316233 DOI: 10.1016/j.dci.2024.105145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 01/10/2024] [Accepted: 02/02/2024] [Indexed: 02/07/2024]
Abstract
Spring viremia of carp virus (SVCV) is a globally distributed virus that causes severe clinical symptoms and high mortality in fish belonging to the families Cyprinidae and Siluridae. To protect the host against viral infection, understanding the relatedness between viral susceptibility and antiviral mechanisms must be crucial. Thus, we evaluated the viral suppression efficacy of ribavirin by measuring the transcription levels of viral and immune genes in vitro. The results showed that following ribavirin treatment after SVCV infection (MOI 0.1), ribavirin inhibited SVCV replication in epithelioma papulosum cyprini (EPC) cells and completely inhibited viral gene (G and N) expression at concentrations above 10 μg/mL at 48 h post-infection. Ribavirin does not directly damage SVCV particles but inhibits early viral replication. In the absence of SVCV infection, the immunological dynamics triggered by ribavirin resulted in upregulated pattern recognition receptors and proinflammatory cytokine-related genes (i.e., PI3K, MYD88, IRAK1, RIG-І, MAVS, Mx1, TNF-α, and NF-κB). Furthermore, EPC cells treated with ribavirin following SVCV infection showed upregulation of PI3K, MYD88, IRAK1, RIG-І, TNF-α, and NF-κB genes within 24 h post-SVCV infection, suggesting that ribavirin positively inhibits the SVCV infection in vitro.

Abstract
Ubiquitin specific protease 5 (USP5) is a vital deubiquitinating enzyme that regulates various physiological functions by removing ubiquitin chains from target proteins. This review provides an overview of the structural and functional characteristics of USP5. Additionally, we discuss the role of USP5 in regulating diverse cellular processes, including cell proliferation, apoptosis, DNA double-strand damage, methylation, heat stress, and protein quality control, by targeting different substrates. Furthermore, we describe the involvement of USP5 in several pathological conditions such as tumors, pathological pain, developmental abnormalities, inflammatory diseases, and virus infection. Finally, we introduce newly developed inhibitors of USP5. In conclusion, investigating the novel functions and substrates of USP5, elucidating the underlying mechanisms of USP5-substrate interactions, intensifying the development of inhibitors, and exploring the upstream regulatory mechanisms of USP5 in detail can provide a new theoretical basis for the treatment of various diseases, including cancer, which is a promising research direction with considerable potential. Overall, USP5 plays a critical role in regulating various physiological and pathological processes, and investigating its novel functions and regulatory mechanisms may have significant implications for the development of therapeutic strategies for cancer and other diseases.

[PMID: 36372204 DOI: 10.1016/j.fsi.2022.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 10/27/2022] [Accepted: 11/04/2022] [Indexed: 06/16/2023]
Abstract
Ubiquitin-specific protease 4 (USP4) is pivotal in negatively regulating the Toll-like receptor (TLR) signaling-mediated innate immune response. Although USP4 has been well studied in mammals, its role in TLR signaling pathways in fish remains largely unknown. In this study, we investigated the role of USP4 (OmUSP4) in regulating TLR response in rainbow trout Oncorhynchus mykiss. OmUSP4 contained the characteristic domains conserved in other USP4s: domain in USP (DUSP), ubiquitin-like (UBL), and the bi-part catalytic domain known as USP. OmUSP4 expression was increased in RTH-149 cells by stimulation with fish-pathogenic bacteria and bacterial ligands. Gain- and loss-of-function experiments revealed that OmUSP4 mitigated the activation of MAPKs and NF-κB, as well as the expression of pro-inflammatory cytokines in LPS-stimulated cells. OmUSP4 interacted with TAK1, a critical mediator in TLR-mediated NF-κB signaling pathways. LPS stimulation increased the K63-linked polyubiquitination of TAK1, which was significantly suppressed when OmUSP4 was compelled to be overexpressed. These results imply that OmUSP4 might function like mammals to downregulate LPS-induced inflammation in rainbow trout by removing the K63-linked ubiquitin chain on TAK1.

Abstract
The ubiquitin-specific proteases (USPs) have attracted particular attention due to their multiple functions in different biological processes. USP12, a member of the USP family, has been demonstrated to exert critical roles in diverse cellular processes, including cell death, cancer and antiviral immunity. Here, we cloned a USP12 homolog from orange spotted grouper (Epinephelus coioides, E. coioides), and its roles in fish RNA virus replication were investigated. EcUSP12 contained a 1119-bp open reading frame (ORF) encoding a 372-amino acid polypeptide, which shared 100.00% and 91.32% identity with USP12 homolog of Etheostoma cragini and Homo sapiens, respectively. Sequence analysis indicated that EcUSP12 contained a conserved peptidase-C19G domain (aa 40-369). qPCR analysis showed that EcUSP12 transcript was most abundant in head kidney and spleen of grouper E. coioides. The expression of EcUSP12 was significantly upregulated in grouper spleen (GS) cells in response to red-spotted grouper nervous necrosis virus (RGNNV) infection. Subcellular localization analysis showed that EcUSP12 was evenly distributed throughout the cytoplasm, and mainly co-localized with endoplasmic reticulum (ER). Interestingly, during RGNNV infection, the endogenous distribution of EcUSP12 was obviously altered, and mostly overlapped with viral coat protein (CP). Co-Immunoprecipitation (Co-IP) assay indicated that EcUSP12 interacted with viral CP. In addition, overexpression of EcUSP12 significantly inhibited the replication of RGNNV in vitro, as evidenced by the decrease in viral gene transcription and protein synthesis during infection. Consistently, knockdown of EcUSP12 by small interfering RNA (siRNA) promoted the replication of RGNNV. Furthermore, EcUSP12 overexpression also increased the transcription level of inflammatory factors and interferon-related genes, including tumor necrosis factor α (TNF-α), interleukin (IL)-1β, IL-6, IL-8, interferon regulatory factor 3 (IRF3), and IRF7. Taken together, our results demonstrated that EcUSP12, as a positive regulator of IFN signaling, interacted with viral CP to inhibit virus infection.

High Expression of Ubiquitin-Specific Protease 39 and Its Roles in Prognosis in Patients with Hepatocellular Carcinoma. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2021:6233175. [PMID: 34987596 PMCID: PMC8723855 DOI: 10.1155/2021/6233175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Accepted: 12/07/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Ubiquitin-specific protease 39 is mainly involved in mRNA splicing and multiple kinds of tumors. Accumulating evidence has shown that USP39 participated in the proliferation and metastasis of hepatocellular carcinoma (HCC). The present study aimed to demonstrate the association between USP39 expression and clinical features and the diagnostic value in HCC based on the Cancer Genome Atlas (TCGA). METHODS A comprehensive analysis for expression of USP39 in HCC was conducted by using multiple databases. The mRNA level of USP39, clinical features, survival rate, and diagnostic value in HCC were analyzed using data from TCGA. The Gene Set Enrichment Analysis (GSEA) was conducted to analyze signaling pathways correlated with USP39 expression in HCC. RESULTS The mRNA level of USP39 was significantly elevated in HCC. The expression of USP39 showed significant correlation with T stage, pathologic stage, tumor status, age, and histologic grade. Logistic analysis demonstrated that high expression of USP39 was significantly associated with older age, tumor status, advanced pathologic stage, T stage, and higher histologic grade. Univariate Cox regression analysis showed that high expression of USP39 was significantly associated with advanced T stage, pathological stage, and tumor status. Multivariate Cox analysis confirmed the result that USP39 expression was an independent prognostic factor for overall survival (OS) in HCC. Results of Kaplan-Meier curves showed that high expression of USP39 had a significant association with poor OS, disease-free survival (DSS), and progress-free interval (PFI) in HCC. ROC analysis indicated that USP39 could be regarded as a promising marker for distinguishing HCC from nontumor. CONCLUSION The increased USP39 might play roles in the progression, diagnosis, and prognosis of HCC.

Abstract
Trim25 is a member of Tripartite Motif (TRIM) family. Previous studies report that trim25 modulates antiviral activity by activating RIG-I. In this study we explored the four alternative splicing (AS) variants X1-X4 of Japanese flounder trim25. The sequences of the AS variants were highly conserved. Expression levels of trim25 X1-X4 were increased after 12 h of poly I:C treatment in vitro. In vivo expression of X2-X4 in liver, kidney (except X2) and blood was significantly up-regulated in early stages of poly I:C treatment. Subcellular localization analysis showed that Trim25 X1-X4 were distributed in different cellular organelles. The recombinant vector pcDNA3.1-Trim25 X1-X4 were successfully overexpressed in Flounder cells and the samples were collected. Expression patterns of RIG-I pathway genes dhx58, traf6, traf2, nfkbia and il-8 were explored in vitro and in vivo after poly I:C treatment, as well as overexpressed samples. The findings of this study imply that AS variants of trim25 confer antiviral activity in Japanese flounder by modulating innate immune response.

Abstract
Alphaherpesvirus infection results in severe health consequences in a wide range of hosts. USPs are the largest subfamily of deubiquitinating enzymes that play critical roles in immunity and other cellular functions. To investigate the role of USPs in alphaherpesvirus replication, we assessed 13 USP inhibitors for PRV replication. Our data showed that all the tested compounds inhibited PRV replication, with the USP14 inhibitor b-AP15 exhibiting the most dramatic effect. Ablation of USP14 also influenced PRV replication, whereas replenishment of USP14 in USP14 null cells restored viral replication. Although inhibition of USP14 induced the K63-linked ubiquitination of PRV VP16 protein, its degradation was not dependent on the proteasome. USP14 directly bound to ubiquitin chains on VP16 through its UBL domain during the early stage of viral infection. Moreover, USP14 inactivation stimulated EIF2AK3/PERK- and ERN1/IRE1-mediated signaling pathways, which were responsible for VP16 degradation through SQSTM1/p62-mediated selective macroautophagy/autophagy. Ectopic expression of non-ubiquitinated VP16 fully rescued PRV replication. Challenge of mice with b-AP15 activated ER stress and autophagy and inhibited PRV infection in vivo. Our results suggested that USP14 was a potential therapeutic target to treat alphaherpesvirus-induced infectious diseases.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2021; 123:104166. [PMID: 34116117 DOI: 10.1016/j.dci.2021.104166] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 05/28/2021] [Accepted: 06/05/2021] [Indexed: 06/12/2023]
Abstract
SVCV infection is known to activate the host's innate immune responses, including the production of interferon (IFN) and interferon-stimulated genes (ISGs). Viperin_sv1 is a novel splice variant of viperin, which is induced during SVCV infection and proves to positively regulate the IFN activation and production. However, the underlying mechanism remains unsolved. In this study, the P protein of SVCV was identified to be the key to induce the mRNA modification and production of viperin_sv1 during the virus infection. Besides, Viperin_sv1 was able to trigger the RLR signaling cascades to activate type-1 interferon response. Additional analysis revealed that viperin_sv1 promoted the stability and function of RIG-I, which result in the production of IFN and ISGs. Moreover, the central SAM domain of viperin_sv1 was demonstrated to be essential for regulating RIG-I protein expression and inducing IFN production. Furthermore, this study also showed that SVCV replication could be inhibited by the viperin_sv1 SAM domain. In conclusion, our study demonstrates that viperin_sv1 reduces the replication of SVCV by promoting the RIG-I protein expression. Our findings identified the antiviral function played by the SAM domain of viperin_sv1 and suggested an antiviral mechanism that is conserved among different species.

Int Immunopharmacol 2020; 87:106763. [PMID: 32683298 DOI: 10.1016/j.intimp.2020.106763] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2020] [Revised: 06/03/2020] [Accepted: 06/28/2020] [Indexed: 02/06/2023]
Abstract
Type I interferons are broadly used for antiviral therapy in clinical. However, the IFNs-mediated antiviral efficacy is commonly restricted by negative regulators. Here, we show that the ubiquitin-specific protease 5 (USP5) inhibits the IFNs-induced p-STAT1 activation (phosphorylation at tyrosine site of STAT1) and its downstream antiviral genes expression. We clarify that USP5 physically interacts with SMURF1 (Smad ubiquitination regulating factor 1) and IFNs signaling regulates the interaction and turnover of both proteins. USP5 enhances the stability and turnover of SMURF1 via decreasing its polyubiquitin expression level, which caused STAT1 to decrease. Importantly, USP5 is also involved in the SMURF1-mediated antiviral response, and its small-molecule inhibitor PYR41 remarkably enhances the IFNs antiviral efficacy. These findings reveal a previously unrecognized function of the USP5 and USP5-SMURF1 axis in regulating the IFNs-mediated antiviral activity.
