Abstract
Ubiquitination (Ub) and deubiquitination are crucial post-translational modifications (PTMs) that precisely regulate protein degradation. Under the catalysis of a cascade of E1-E2-E3 ubiquitin enzymes, ubiquitination extensively regulates protein degradation exerting direct impact on various cellular processes, while deubiquitination opposes the effect of ubiquitination and prevents proteins from degradation. Notably, such dynamic modifications have been widely investigated to be implicated in cell cycle, transcriptional regulation, apoptosis and so on. Therefore, dysregulation of ubiquitination and deubiquitination could lead to certain diseases through abnormal protein accumulation and clearance. Increasing researches have revealed that the dysregulation of catalytic regulators of ubiquitination and deubiquitination triggers imbalance of cartilage homeostasis that promotes osteoarthritis (OA) progression. Hence, it is now believed that targeting on Ub enzymes and deubiquitinating enzymes (DUBs) would provide potential therapeutic pathways. In the following sections, we will summarize the biological role of Ub enzymes and DUBs in the development and progression of OA by focusing on the updating researches, with the aim of deepening our understanding of the underlying molecular mechanism of OA pathogenesis concerning ubiquitination and deubiquitination, so as to explore novel potential therapeutic targets of OA treatment.

Abstract
Ubiquitination and deubiquitylation are pivotal posttranslational modifications essential for regulating cellular protein homeostasis and are implicated in the development of human diseases. Ubiquitin-specific protease 3 (USP3), a member of the ubiquitin-specific protease family, serves as a key deubiquitylation enzyme, playing a critical role in diverse cellular processes including the DNA damage response, cell cycle regulation, carcinogenesis, tumor cell proliferation, migration, and invasion. Despite notable research efforts, our current understanding of the intricate and context-dependent regulatory networks governing USP3 remains incomplete. This review aims to comprehensively synthesize existing published works on USP3, elucidating its multifaceted roles, functions, and regulatory mechanisms, while offering insights for future investigations. By delving into the complexities of USP3, this review strives to provide a foundation for a more nuanced understanding of its specific roles in various cellular processes. Furthermore, the exploration of USP3's regulatory networks may uncover novel therapeutic strategies targeting this enzyme in diverse human diseases, thereby holding promising clinical implications. Overall, an in-depth comprehension of USP3's functions and regulatory pathways is crucial for advancing our knowledge and developing targeted therapeutic approaches for human diseases.

Abstract
Protein ubiquitination is a post-translational modification that entails the covalent attachment of the small protein ubiquitin (Ub), which acts as a signal to direct protein stability, localization, or interactions. The Ub code is written by a family of enzymes called E3 Ub ligases (∼600 members in humans), which can catalyze the transfer of either a single ubiquitin or the formation of a diverse array of polyubiquitin chains. This code can be edited or erased by a different set of enzymes termed deubiquitinases (DUBs; ∼100 members in humans). While enzymes from these distinct families have seemingly opposing activities, certain E3-DUB pairings can also synergize to regulate vital cellular processes like gene expression, autophagy, innate immunity, and cell proliferation. In this review, we highlight recent studies describing Ub ligase-DUB interactions and focus on their relationships.

Abstract
Microbial products, such as lipopolysaccharide (LPS), can elicit efficient innate immune responses against invading pathogens. However, priming with LPS can induce a form of innate immune memory, termed innate immune "tolerance", which blunts subsequent NF-κB signaling. Although epigenetic and transcriptional reprogramming has been shown to play a role in innate immune memory, the involvement of post-translational regulation remains unclear. Here, we report that ubiquitin-specific protease 3 (USP3) participates in establishing "tolerance" innate immune memory through non-transcriptional feedback. Upon NF-κB signaling activation, USP3 is stabilized and exits the nucleus. The cytoplasmic USP3 specifically removes the K63-linked polyubiquitin chains on MyD88, thus negatively regulating TLR/IL1β-induced inflammatory signaling activation. Importantly, cytoplasmic translocation is a prerequisite step for USP3 to deubiquitinate MyD88. Additionally, LPS priming could induce cytoplasmic retention and faster and stronger cytoplasmic translocation of USP3, enabling it to quickly shut down NF-κB signaling upon the second LPS challenge. This work identifies a previously unrecognized post-translational feedback loop in the MyD88-USP3 axis, which is critical for inducing normal "tolerance" innate immune memory.

Abstract
Ubiquitination (or ubiquitylation) and de-ubiquitination, which are both post-translational modifications (PTMs) of proteins, have become a research hotspot in recent years. Some ubiquitinated or de-ubiquitinated signaling proteins have been found to promote or suppress innate immunity through Toll-like receptor (TLR), RIG-like receptor (RIG-I-like receptor, RLR), NOD-like receptor (NLR), and the cyclic guanosine monophosphate (GMP)-adenosine monophosphate (AMP) synthase (cGAS)-STING pathway. This article aimed to provide a review on the role of ubiquitination and de-ubiquitination, especially ubiquitin ligase enzymes and de-ubiquitinating enzymes, in the above four pathways. We hope that our work can contribute to the research and development of treatment strategies for innate immunity-related diseases such as inflammatory bowel disease.

Abstract
Several members of the ubiquitin-specific proteases (USPs) family have been revealed to regulate the progression of osteoarthritis (OA). The current study aimed to investigate the role and the underlying mechanism of USP25 in IL-1β-induced chondrocytes and OA rat model. It was discovered that IL-1β stimulation upregulated USP25, increased ROS level, and suppressed cell viability in rat chondrocytes. Besides, USP25 knockdown alleviated IL-1β-induced injury by decreasing ROS level, attenuating pyroptosis, and downregulating the expression of IL-18, NLRP3, GSDMD-N, active caspase-1, MMP-3, and MMP-13. Furthermore, we discovered that USP25 affected the IL-1β-induced injury in chondrocytes in a ROS-dependent manner. Moreover, USP25 was revealed to interact with TXNIP, and USP25 knockdown increased the ubiquitination of TXNIP. The pro-OA effect of USP25 abundance could be overturned by TXNIP suppression in IL-1β-induced chondrocytes. Finally, in vivo experiment results showed that USP25 inhibition alleviated cartilage destruction in OA rats. In conclusion, we demonstrated that USP25 stimulated the overproduction of ROS to activate the NLRP3 inflammasome via regulating TXNIP, resulting in increased pyroptosis and inflammation in OA.

Abstract
Osteoarthritis is non-inflammatory degenerative joint arthritis, which exacerbates disability in elder persons. The molecular mechanisms of osteoarthritis are elusive. Ubiquitination, one type of post-translational modifications, has been demonstrated to accelerate or ameliorate the development and progression of osteoarthritis via targeting specific proteins for ubiquitination and determining protein stability and localization. Ubiquitination process can be reversed by a class of deubiquitinases via deubiquitination. In this review, we summarize the current knowledge regarding the multifaceted role of E3 ubiquitin ligases in the pathogenesis of osteoarthritis. We also describe the molecular insight of deubiquitinases into osteoarthritis processes. Moreover, we highlight the multiple compounds that target E3 ubiquitin ligases or deubiquitinases to influence osteoarthritis progression. We discuss the challenge and future perspectives via modulation of E3 ubiquitin ligases and deubiquitinases expression for enhancement of the therapeutic efficacy in osteoarthritis patients. We conclude that modulating ubiquitination and deubiquitination could alleviate the osteoarthritis pathogenesis to achieve the better treatment outcomes in osteoarthritis patients.

Abstract
Stabilization of bone structure and function involves multiple cell-to-cell and molecular interactions, in which the regulatory functions of post-translational modifications such as ubiquitination and deubiquitination shouldn't be underestimated. As the largest family of deubiquitinating enzymes, the ubiquitin-specific proteases (USPs) participate in the development of bone homeostasis and bone-related diseases through multiple classical osteogenic and osteolytic signaling pathways, such as BMP/TGF-β pathway, NF-κB/p65 pathway, EGFR-MAPK pathway and Wnt/β-catenin pathway. Meanwhile, USPs may also broadly regulate regulate hormone expression level, cell proliferation and differentiation, and may further influence bone homeostasis from gene fusion and nuclear translocation of transcription factors. The number of patients with bone-related diseases is currently enormous, making exploration of their pathogenesis and targeted therapy a hot topic. Pathological increases in the levels of inflammatory mediators such as IL-1β and TNF-α lead to inflammatory bone diseases such as osteoarthritis, rheumatoid arthritis and periodontitis. While impaired body metabolism greatly increases the probability of osteoporosis. Abnormal physiological activity of bone-associated cells results in a variety of bone tumors. The regulatory role of USPs in bone-related disease has received particular attention from academics in recent studies. In this review, we focuse on the roles and mechanisms of USPs in bone homeostasis and bone-related diseases, with the expectation of informing targeted therapies in the clinic.

Ubiquitin-specific protease 3 facilitates cell proliferation by deubiquitinating pyruvate kinase L/R in gallbladder cancer. J Transl Med 2022; 102:1367-1376.

Abstract
Ubiquitin-specific protease 3 (USP3), a kind of cysteine protease, is a crucial family member of deubiquitinating enzymes. USP3 is aberrantly expressed in several tumors, which may contribute to cancer progression. However, the role of USP3 in gallbladder cancer (GBC) is still unknown. In the current study, we detected the expression of USP3 in GBC tissues, measured its contribution to the cell proliferation in GBC progression, and further studied the underlying mechanism of USP3 in GBC through pyruvate kinase L/R (PKLR; a kind of glycolytic enzyme). We found that the expression of USP3 in GBC tissues were higher than that of adjacent tissues, and the protein levels of USP3 and PKLR were positively correlated. Additionally, overexpressed USP3 significantly promoted cell proliferation in vitro and tumor growth in vivo, while the silencing of USP3 inhibited proliferation and tumor growth. Glycolysis in GBC cells ws promoted by the USP3 overexpression and inhibited bye USP3 downregulation. Moreover, the loss of USP3 promoted the ubiquitination and weakened the stability of PKLR. Results of the rescue assay confirmed that PKLR knockdown suppressed USP3-induced oncogenic activity in USP3 overexpressed GBC cells. These findings imply that USP3 is an essential positive regulator in GBC progression, and USP3-PKLR plays a vital role in the progression and metabolism of GBC. Ubiquitin-specific protease 3 (USP3), a cysteine protease, is deubiquitinating enzyme. USP3 is aberrantly expressed in several types of tumors. The authors show that USP3 is an important positive regulator in gallbladder cancer progression, and that pyruvate kinase L/R plays a key role in the progression of GBC.

Abstract
Relatively low-grade inflammatory of osteoarthritic joints is characterized by synovitis and a catabolic and proinflammatory state of the chondrocytes and plays an important role in osteoarthritis (OA) initiation and exacerbation. Our previous research showed cardiac glycoside compounds might be effective in OA synovitis. However, the effect of digoxin (DIG), an FDA-approved cardenolide, on inflammation inhibition of osteoarthritic joints has not been investigated. In the present study, a western blot analysis and immunofluorescence staining revealed that DIG alleviated OA synovitis by inhibiting the M1-like polarization of synovial macrophages in OA patients and collagenase-induced OA (CIOA, with considerable synovitis) mice. Subsequently, the exosomes produced by macrophages and M1-like macrophages treated with or without DIG were isolated and identified. According to miRNA sequencing analysis of these exosomes and subsequent target activity assays, we confirmed DIG controls OA inflammatory microenvironment and promotes chondrogenesis by, at least partly, downregulating the M1-like macrophage-derived exosomal miR-146b-5p/Usp3&Sox5 axis in vitro and in vivo. This research provides reliable experimental evidence supporting the clinical application of DIG as a disease-modifying drug for inflammation-associated OA. Additionally, the spectrum of diseases of inflammation controlled by DIG has been broadened, which prompting research interest in the new function of an "old" FDA-approved drug.

BIOMED RESEARCH INTERNATIONAL 2022; 2022:2064013. [PMID: 35774277 PMCID: PMC9239828 DOI: 10.1155/2022/2064013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 05/13/2022] [Accepted: 06/02/2022] [Indexed: 11/21/2022]
Abstract
Mycoplasma pneumoniae pneumonia (MPP) represents a common respiratory disease in children patients. Kukoamine A (KuA) is a spermine alkaloid found in the Chinese herb Cortex Lycii radices, which has a variety of pharmacological properties. However, no study has been reported on the role of KuA in MPP. Exosomes, a type of lipid bilayer-enclosed extracellular vesicles, can be delivered to the target cells, where they regulate function and physiology. With the use of human alveolar basal epithelial cells (HABECs) as an in vitro model, in this study, we sought to characterize the changes in levels of superoxide dismutase 2 (SOD2) and proinflammatory cytokines including IL-6 and TNF-α in HABECs in response to exosomes, which were isolated from peripheral blood serum of MPP patients. We found that, compared to normal, MPP patients exhibited a significant up-regulated miR-222-3p. Further, exosomal miR-222-3p downregulated SOD2 activity but promoted nuclear NF-κB activity and expression of IL-6 and TNF-α in HABECs, ultimately leading to an oxidative stress condition. Interestingly, such stimulating effects were attenuated by the pretreatment of KuA. This study suggests a critical role possessed by KuA in MPP by regulating the miR-222-3p/SOD2 axis, which represents a promising strategy for the treatment of MPP.

Abstract
zong non-coding RNAs (lncRNAs) have been identified as crucial effector in modulating the progression of assorted malignancies. In our study, the main aim was to unveil the role and the underlying regulatory mechanism of long intergenic non-protein coding RNA 1605 (LINC01605) in nasopharyngeal carcinoma (NPC). RT-qPCR analysis results suggested that LINC01605 was upregulated in NPC cells. According to the results of function experiments, LINC01605 promoted NPC cell proliferation and impeded cell apoptosis. The oncogenic role of LINC01605 in NPC was further validated by animal experiments. Additionally, we verified that LINC01605 regulated Ikbkb expression to promote the nuclear translocation of p65 and thereby activated the NF-κB pathway in NPC cells. Mechanism experiments further suggested that LINC01605 could regulate Ikbkb expression via sponging miR-942-5p. Moreover, LINC01605 recruited IGF2BP2 to stabilize ubiquitin-specific protease 3 (USP3) mRNA and thereby enhanced the stability of IkB subunit beta (IKKβ) protein. In addition, p65 acted as a transcription activator to upregulate LINC01605 in NPC cells. In conclusion, this study demonstrated a positive feedback loop between LINC01605 and the NF-κB signalling pathway that promoted NPC cell growth, thus providing new insights to better understand NPC.

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.

MicroRNA-146-5p Promotes Pulmonary Artery Endothelial Cell Proliferation under Hypoxic Conditions through Regulating USP3. DISEASE MARKERS 2021; 2021:3668422. [PMID: 34917199 PMCID: PMC8670967 DOI: 10.1155/2021/3668422] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Accepted: 11/19/2021] [Indexed: 12/12/2022]
Abstract
Objective MicroRNAs play a pivotal role in the progression of pulmonary hypertension (PAH). Although microRNA-146-5p is specifically expressed in many diseases, but in PAH, its role remains elusive. Patients and Methods. 30 patients with PAH and 20 healthy volunteers in our hospital were enrolled, and their serum samples were extracted for the detection of microRNA-146-5p and ubiquitin specific protease 3 (USP3) expression. In addition, the interaction between microRNA-146-5p and USP3 was examined by luciferase reporting assay. Furthermore, the potential mechanism was explored by cell counting kit-8 (CCK-8), 5-ethynyl-2′-deoxyuridine (EdU), and Western blotting experiments. Results It was found that microRNA-146-5p was higher in PAH patients than in healthy volunteers. Meanwhile, in hypoxia-induced human pulmonary artery endothelial cell lines (HPAECs), microRNA-146-5p expression was dramatically downregulated while USP3 protein expression was conversely upregulated. Under hypoxic conditions, microRNA-146-5p mimics was able to prompt the growth of HPAECs. In addition, after overexpression of microRNA-146-5p, luciferase reporting assay revealed a reduced luciferase activity of the reporter gene containing the USP3 3′-untranslated region, and a reduction of USP3 protein expression was also confirmed. However, USP3 overexpression partially attenuated the impact of upregulated microRNA-146-5p on the proliferation capacity of HPAECs. Conclusions MicroRNA-146-5p was able to enhance the proliferation ability of HPAEC cells under hypoxic conditions through targeting USP3, suggesting the microRNA-146-5p/USP3 axis may act as a target for PAH treatment.

Abstract
OBJECTIVE Osteoarthritis (OA) is a degenerative joint disease characterized by deterioration of articular cartilage functions. Previous studies have confirmed the role of circular RNAs (circRNAs) in OA, but the role of mechanical stress-related circRNA (circRNA-MSR) in OA is unknown. DESIGN The human chondrocytes C28/I2 were cultured and treated with lipopolysaccharide (LPS) to establish the OA model. The mRNA and protein levels were measured by qRT-PCR or Western blot. Cell viability was analyzed by MTT assay. Flow cytometry was carried out to detect cell apoptosis. The levels of TNF-α, IL-1β, and IL-6 were determined by enzyme-linked immunosorbent assay (ELISA). Pull-down assay was conducted to measure circRNA-MSR-related miRNA. Dual-luciferase reporter gene detection was performed to detect the target relationships between miR-643 and circRNA-MSR or Mitogen-activated protein kinase kinase 6 (MAP2K6). The RNA-fluorescence in situ hybridization (RNA-FISH) assay was conducted to verify the localization of circRNA-MSR and miR-643. RESULTS The expressions of circRNA-MSR were upregulated in LPS stimulated C28/I2 cells. Knockdown of circRNA-MSR can inhibit LPS-induced apoptosis, inflammatory response, and extracellular matrix (ECM) degradation, and promote cell C28/I2 cells proliferation. Moreover, circRNA-MSR directly targeted miR-643. RNA-FISH exhibited that circRNA-MSR may act as a competing endogenous RNA (ceRNA) of miR-643. Over-expression of miR-643 could alleviate LPS-induced C28/I2 chondrocyte injury and promote cell proliferation. Besides, miR-643 directly bound to MAP2K6 mRNA. MiR-643 inhibition or MAP2K6 overexpression can reverse the role of circRNA-MSR knockdown on LPS-treated chondrocytes. CONCLUSION circRNA-MSR can upregulate MAP2K6 by targeting miR-643, thereby inhibiting cell proliferation and promoting apoptosis of C28/I2 cells.

Abstract
OBJECTIVE Osteoarthritis (OA) is a severe and common degenerative disease; however, the exact pathology of OA is undefined. Our study is designed to investigate the underlying molecular mechanism of OA with bioinformatic tools. DESIGN Three updated GEO datasets: GSE55235, GSE55457, and GSE82107 were selected for data analyzing. R software was utilized to screen and confirm the candidate differentially expressed genes in the development of OA. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes pathway were performed to identify the enriched GO terms and signaling pathways. Protein and protein interaction (PPI) models were built to observe the connected relationship among each potential protein. RESULTS A total of 113 upregulated genes and 161 downregulated genes were found by integrating 3 datasets. GO enrichment indicated that cell differentiation, cellular response to starvation, and negative regulation of phosphorylation were important biological processes. KEGG enrichment indicated that FoxO, IL-17 signaling pathways, and osteoclast differentiation mainly participated in the progression of OA. Combining the molecular function and PPI results, ubiquitylation was identified as a pivotal bioactive reaction involved in OA. CONCLUSION Our study provided updated candidate genes and pathways of OA, which may benefit further research and treatment for OA.

Abstract
Osteoarthritis (OA) affects approximately 12% of the aging Western population. The sirtuin/forkhead box O (SIRT/FOXO) signaling pathway plays essential roles in various biological processes. Despite it has been demonstrated that ubiquitin-specific protease 3 (USP3) inhibits chondrocyte apoptosis induced by interleukin (IL)-1β, the role of USP3/SIRT3/FOXO3 in the senescence of chondrocytes in OA is unclear. This study initially isolated articular chondrocytes and investigated the role of USP3 in IL-1β-induced senescence of chondrocytes. After USP3 was overexpressed or silenced by lentivirus, expressions of genes and proteins were detected using quantitative polymerase chain reaction and immunoblotting, respectively. Cell cycle analysis was performed using flow cytometry. Reactive oxygen species (ROS) levels and senescence were analyzed. Then, SIRT3 was inhibited or overexpressed to explore the underlying mechanism. We found that overexpression of USP3 hindered IL-1β-mediated cell cycle arrest, ROS generation, and chondrocyte senescence. The inhibition of SIRT3 blocked the protective effect of USP3 on cell senescence, whereas the overexpression of SIRT3 abolished USP3-silencing-induced cell senescence. Furthermore, SIRT3 attenuated cell senescence, probably by deacetylating FOXO3. USP3 upregulated SIRT3 to deacetylate FOXO3 and attenuated IL-1β-induced chondrocyte senescence. This study demonstrated that USP3 probably attenuated IL-1β-mediated chondrocyte senescence by deacetylating FOXO3 via SIRT3.

Abstract
PURPOSE OF REVIEW To date, a vast amount of information regarding ubiquitination (Ub) and ubiquitylation-like (Ubl) modification-related mechanisms has been reported in the context of skeletal cell homeostasis and diseases. In this review, we mainly focus on recent findings regarding the contribution of enzymatic machinery that directly adds or removes Ub and Ubl modifications from protein targets in chondrocyte homeostasis and osteoarthritis (OA) development. RECENT FINDINGS Mechanisms that promote homeostasis of articular chondrocytes are crucial for maintaining the integrity of articular joints to prevent osteoarthritis development. Articular chondrocytes are postmitotic cells that continuously produce and remodel cartilage matrix. In addition, the long lifespan of chondrocytes makes them susceptible to accumulating cellular damage. Ub and the evolutionarily conserved Ubl modifications, such as SUMOylation, ATGylation, and UFMylation, play important roles in promoting chondrocyte homeostasis, including regulating cell signaling and protein stability, resolving cellular stresses and inflammation, and maintaining differentiation and survival of chondrocytes. Uncovering new components/functions of Ub/Ubl modification machinery may provide novel drug targets to treat OA.

Abstract
Deubiquitinases are widely involved in the regulation of the virus-triggered type I interferon (IFN) signaling. Here, we found sea perch (Lateolabrax japonicus) ubiquitin-specific protease 5 (LjUSP5) was a negative regulatory factor of the red-spotted grouper nervous necrosis virus (RGNNV)-triggered IFN response. LjUSP5 encoded a polypeptide of 830 amino acids, containing a zinc finger UBP domain (residues 197-270 aa), two ubiquitin-associated domains (residues 593-607 aa; 628-665 aa), and one UBP domain (residues 782-807 aa), and shared the closest genetic relationship with the USP5 of Larimichthys crocea. Quantitative RT-PCR analysis showed that LjUSP5 was ubiquitously expressed and up-regulated significantly in all inspected tissues post RGNNV infection, and its transcripts significantly increased in brain, liver and kidney tissues post RGNNV infection. LjUSP5 was up-regulated in cultured LJB cells after poly I:C and RGNNV treatments. In addition, overexpression of LjUSP5 significantly inhibited the activation of zebrafish IFN 1 promoter and promoted RGNNV replication in vitro. Furthermore, LjUSP5 inhibited the activation of zebrafish IFN 1 promoter induced by key genes of retinoic acid-inducible gene I-like receptors signaling pathway. Our findings provides useful information for further elucidating the mechanism underlying NNV infection.

Abstract
Osteoarthritis (OA) is an age-related chronic joint degenerative disease. Interleukin 1 beta (IL-1β) is considered a marker for the progression of OA. In this study, we found that Ubiquitin-Specific Peptidase 49 (USP49) was significantly less expressed in OA patients compared with healthy individuals. Treating primary rat chondrocytes with different concentrations of IL-1β resulted in decreased Usp49 expression, while Usp49 overexpression could attenuate IL-1β-induced chondrocyte apoptosis by promoting Axin deubiquitination. The deubiquitination of Axin led to the accumulation of the protein, which in turn resulted in β-catenin degradation and Wnt/β-catenin signaling cascade inhibition. Interestingly, we also found that [6]-gingerol, an anti-OA drug, could upregulate the protein level of Usp49 and suppress the Wnt/β-catenin signaling cascade in primary rat chondrocytes. Taken together, our study not only demonstrates that Usp49 can negatively regulate the progression of OA by inhibiting the Wnt/β-catenin signaling cascade, but also elucidates the underlying molecular mechanisms.

Lin Y, Mao F, Zhang X, Xu D, He Z, Li J, Xiang Z, Zhang Y, Yu Z. TRAF6 suppresses the apoptosis of hemocytes by activating pellino in Crassostrea hongkongensis. DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2020; 103:103501. [PMID: 31634519 DOI: 10.1016/j.dci.2019.103501] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Revised: 09/25/2019] [Accepted: 09/25/2019] [Indexed: 06/10/2023]
Abstract
Tumor necrosis factor receptor-associated factor 6 (TRAF6), an E3 ubiquitin ligase, participates in both innate and adaptive immunity and regulates the apoptotic process. In this study, we observed that an ortholog of TRAF6 could inhibit the activity of p53 and suppress the apoptotic process in the Hong Kong oyster, Crassostrea hongkongensis. To investigate the possible molecular mechanism of the ChTRAF6-induced antiapoptotic effect, a GST pull-down screening assay was conducted, and ChPellino was found to physically interact with ChTRAF6. In addition, the interaction between them was confirmed by Co-immunoprecipitation. Furthermore, western blotting revealed that the phosphorylation level of ChPellino was decreased after the RNAi of ChTRAF6, demonstrating that ChTRAF6 may be an upstream regulator of Pellino activation. Furthermore, the apoptosis level of hemocytes increased after ChPellino knockdown, and ChPellino overexpression suppressed ChTRAF6-dependent p53 activation. Taken together, these results indicate that ChPellino plays a critical role in suppressing ChTRAF6-dependent anti-apoptosis in the hemocytes of Crassostrea hongkongensis.
