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.

Abstract
Polycomb group (PcG) proteins are highly conserved proteins assembled into two major types of complexes, PRC1 and PRC2, involved in the epigenetic silencing of a wide range of gene expression programs regulating cell fate and tissue development. The crucial role of PRC1 and PRC2 in the fundamental cellular processes and their involvement in human pathologies such as cancer attracted intense attention over the last few decades. Here, we review recent advancements regarding PRC1 and PRC2 function using the zebrafish model. We point out that the unique characteristics of the zebrafish model provide an exceptional opportunity to increase our knowledge of the role of the PRC1 and PRC2 complexes in tissue development, in the maintenance of organ integrity and in pathology.

Abstract
The ubiquitin system regulates a wide variety of cellular functions. Not surprisingly, dysregulation of the ubiquitin system is associated with various disorders. Therefore, drugs that can modulate the functions of the ubiquitin system have been actively developed to treat these disorders. Chemical knockdown of pathogenic proteins using the ubiquitin-proteasome system is also a promising approach. The ubiquitin system regulates the assemble and disassemble of primary cilia through balanced control over the ubiquitination and deubiquitination of ciliary proteins. Primary cilia are antenna-like structures present in many vertebrate cells that sense and transduce extracellular cues to control cellular processes such as proliferation and differentiation. Impairment of primary cilia is associated with many diseases, including cancer and ciliopathy, a group of multisystem developmental disorders. In this review, we focus on the role of the ubiquitin system on cilia-related disorders and discuss the possibility of the ubiquitin system as therapeutic targets for these diseases through regulation of primary cilia formation.

Abstract
Cilia are antenna-like structures present in many vertebrate cells. These organelles detect extracellular cues, transduce signals into the cell, and play an essential role in ensuring correct cell proliferation, migration, and differentiation in a spatiotemporal manner. Not surprisingly, dysregulation of cilia can cause various diseases, including cancer and ciliopathies, which are complex disorders caused by mutations in genes regulating ciliary function. The structure and function of cilia are dynamically regulated through various mechanisms, among which E3 ubiquitin ligases and deubiquitinases play crucial roles. These enzymes regulate the degradation and stabilization of ciliary proteins through the ubiquitin-proteasome system. In this review, we briefly highlight the role of cilia in ciliopathy and cancer; describe the roles of E3 ubiquitin ligases and deubiquitinases in ciliogenesis, ciliopathy, and cancer; and highlight some of the E3 ubiquitin ligases and deubiquitinases that are potential therapeutic targets for these disorders.

FISH & SHELLFISH IMMUNOLOGY 2020; 103:239-247.

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.

Proteasomal inhibition attenuates craniofacial malformations in a zebrafish model of Treacher Collins Syndrome. Biochem Pharmacol 2019; 163:362-370.

Abstract
Treacher Collins Syndrome (TCS) is a congenital disease characterized by defects in the craniofacial skeleton and absence of mental alterations. Recently we modelled TCS in zebrafish (Danio rerio) embryos through the microinjection of Morpholino® oligonucleotides blocking the translation of the ortholog of the main causative gene (TCOF1). We showed that Cnbp, a key cytoprotective protein involved in normal rostral head development, was detected in lower levels (without changes in its mRNA expression) in TCS-like embryos. As previous reports suggested that Cnbp is degraded through the proteasomal pathway, we tested whether proteasome inhibitors (MG132 and Bortezomib (Velcade®, Millennium laboratories)) were able to ameliorate cranial skeleton malformations in TCS. Here we show that treatment with both proteasome inhibitors produced a robust craniofacial cartilage phenotype recovery. This recovery seems to be consequence of a decreased degradation of Cnbp in TCS-like embryos. Critical TCS manifestations, such as neuroepithelial cell death and cell redox imbalance were attenuated. Thus, proteasome inhibitors may offer an opportunity for TCS molecular and phenotypic manifestation's prevention. Although further development of new safe inhibitors compatible with administration during pregnancy is required, our results encourage this therapeutic approach.
