Yao B, Hu W, Chen Y, Li J, Jiang K, Dou J. Pan-cancer analysis of the TRAF family genes and their correlation with prognosis, TME, immune and drug sensitivity. Eur J Med Res 2024; 29:307. [PMID: 38825674 PMCID: PMC11145793 DOI: 10.1186/s40001-024-01875-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 04/29/2024] [Indexed: 06/04/2024] Open
Abstract
BACKGROUND Tumor necrosis factor receptor-associated factors family genes play a pivotal role in tumorigenesis and metastasis, functioning as adapters or E3 ubiquitin ligases across various signaling pathways. To date, limited research has explored the association between tumor necrosis factor receptor-associated factors family genes and the clinicopathological characteristics of tumors, immunity, and the tumor microenvironment (TME). This comprehensive study investigates the relationship between tumor necrosis factor receptor-associated factors family and prognosis, TME, immune response, and drug sensitivity in a pan-cancer context. METHODS Utilizing current public databases, this study examines the expression levels and prognostic significance of tumor necrosis factor receptor-associated factors family genes in a pan-cancer context through bioinformatic analysis. In addition, it investigates the correlation between tumor necrosis factor receptor-associated factors expression and various factors, including the TME, immune subtypes, stemness scores, and drug sensitivity in pan-cancer. RESULTS Elevated expression levels of tumor necrosis factor receptor-associated factor 2, 3, 4, and 7 were observed across various cancer types. Patients exhibiting high expression of these genes generally faced a worse prognosis. Furthermore, a significant correlation was noted between the expression of tumor necrosis factor receptor-associated factors family genes and multiple dimensions of the TME, immune subtypes, and drug sensitivity.

Abstract
BACKGROUND TRAF7-related cardiac, facial, and digital anomalies with developmental delay (CAFDADD), a multisystemic neurodevelopmental disorder caused by germline missense variants in the TRAF7 gene, exhibits heterogeneous clinical presentations. METHODS We present a detailed description of 11 new TRAF7-related CAFDADD cases, featuring eight distinct variants, including a novel one. RESULTS Phenotypic analysis and a comprehensive review of the 58 previously reported cases outline consistent clinical presentations, emphasizing dysmorphic features, developmental delay, endocrine manifestations, and cardiac defects. In this enlarged collection, novelties include a wider range of cognitive dysfunction, with some individuals exhibiting normal development despite early psychomotor delay. Communication challenges, particularly in expressive language, are prevalent, necessitating alternative communication methods. Autistic traits, notably rigidity, are observed in the cohort. Also, worth highlighting are hearing loss, sleep disturbances, and endocrine anomalies, including growth deficiency. Cardiac defects, frequently severe, pose early-life complications. Facial features, including arched eyebrows, contribute to the distinct gestalt. A novel missense variant, p.(Arg653Leu), further underscores the complex relationship between germline TRAF7 variants and somatic changes linked to meningiomas. CONCLUSIONS Our comprehensive analysis expands the phenotypic spectrum, emphasizing the need for oncological evaluations and proposing an evidence-based schedule for clinical management. This study contributes to a better understanding of TRAF7-related CAFDADD, offering insights for improved diagnosis, intervention, and patient care.

Abstract
Alternative splicing serves as a pivotal source of complexity in the transcriptome and proteome, selectively connecting various coding elements to generate a diverse array of mRNAs. This process encodes multiple proteins with either similar or distinct functions, contributing significantly to the intricacies of cellular processes. The role of alternative splicing in mammalian immunity has been well studied. Remarkably, the immune system of fish shares substantial similarities with that of humans, and alternative splicing also emerges as a key player in the immune processes of fish. In this review, we offer an overview of alternative splicing and its associated functions in the immune processes of fish, and summarize the research progress on alternative splicing in the fish immunity. Furthermore, we review the impact of alternative splicing on the fish immune system's response to external stimuli. Finally, we present our perspectives on future directions in this field. Our aim is to provide valuable insights for the future investigations into the role of alternative splicing in immunity.

Abstract
Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infections in the USA and of preventable blindness worldwide. This obligate intracellular pathogen replicates within a membrane-bound inclusion, but how it acquires nutrients from the host while avoiding detection by the innate immune system is incompletely understood. C. trachomatis accomplishes this in part through the translocation of a unique set of effectors into the inclusion membrane, the inclusion membrane proteins (Incs). Incs are ideally positioned at the host-pathogen interface to reprogram host signaling by redirecting proteins or organelles to the inclusion. Using a combination of co-affinity purification, immunofluorescence confocal imaging, and proteomics, we characterize the interaction between an early-expressed Inc of unknown function, Tri1, and tumor necrosis factor receptor-associated factor 7 (TRAF7). TRAF7 is a multi-domain protein with a RING finger ubiquitin ligase domain and a C-terminal WD40 domain. TRAF7 regulates several innate immune signaling pathways associated with C. trachomatis infection and is mutated in a subset of tumors. We demonstrate that Tri1 and TRAF7 specifically interact during infection and that TRAF7 is recruited to the inclusion. We further show that the predicted coiled-coil domain of Tri1 is necessary to interact with the TRAF7 WD40 domain. Finally, we demonstrate that Tri1 displaces the native TRAF7 binding partners, mitogen-activated protein kinase kinase kinase 2 (MEKK2), and MEKK3. Together, our results suggest that by displacing TRAF7 native binding partners, Tri1 has the capacity to alter TRAF7 signaling during C. trachomatis infection.IMPORTANCEChlamydia trachomatis is the leading cause of bacterial sexually transmitted infections in the USA and preventable blindness worldwide. Although easily treated with antibiotics, the vast majority of infections are asymptomatic and therefore go untreated, leading to infertility and blindness. This obligate intracellular pathogen evades the immune response, which contributes to these outcomes. Here, we characterize the interaction between a C. trachomatis-secreted effector, Tri1, and a host protein involved in innate immune signaling, TRAF7. We identified host proteins that bind to TRAF7 and demonstrated that Tri1 can displace these proteins upon binding to TRAF7. Remarkably, the region of TRAF7 to which these host proteins bind is often mutated in a subset of human tumors. Our work suggests a mechanism by which Tri1 may alter TRAF7 signaling and has implications not only in the pathogenesis of C. trachomatis infections but also in understanding the role of TRAF7 in cancer.

Abstract
TRAF7-related disorders represent some of the rarest inherited disorders, exhibiting clinical features that overlap with cardiac, facial, and digital anomalies with developmental delay (CAFDADD) syndrome, as well as blepharophimosis-mental retardation syndrome (BMRS). A 36-year-old male, presenting with total blindness, blepharophimosis, and intellectual disability, was admitted for the assessment of resting dyspnea several months previously. He had a history of being diagnosed with obstructive sleep apnea (OSA). Transesophageal and transthoracic echocardiography unveiled right ventricular dilatation without significant pulmonary hypertension, bicuspid aortic valve with aortic root aneurysm, and aortic regurgitation in the proband. Sanger sequencing identified a de novo TRAF7 variant (c.1964G>A; p.Arg655Gln). Subsequently, aortic root replacement using the Bentall procedure was performed. However, despite the surgery, he continued to experience dyspnea. Upon re-evaluating OSA with polysomnography, it was discovered that continuous positive airway pressure support alleviated his symptoms. The underlying cause of his symptoms was attributed to OSA, likely exacerbated by the vertebral anomaly and short neck associated with CAFDADD syndrome. Clinicians should be attentive to the symptoms associated with OSA as it is a potentially serious medical condition in patients with TRAF7 variants.

Genome-wide mapping of regulatory variants for temperature- and salinity-adaptive genes reveals genetic basis of genotype-by-environment interaction in Crassostrea ariakensis. ENVIRONMENTAL RESEARCH 2023; 236:116614. [PMID: 37442261 DOI: 10.1016/j.envres.2023.116614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 06/14/2023] [Accepted: 07/09/2023] [Indexed: 07/15/2023]
Abstract
Regulatory variants in gene expression serve as bridges linking genetic variation and phenotypic plasticity. Environmental conditions typically influence the effects of regulatory variants on phenotypic plasticity; however, such genotype-by-environment interactions (G × E) are poorly understood. This study aimed to investigate the genetic basis of G × E in estuarine oyster (Crassostrea ariakensis), which is an important model animal for studying environmental adaption owing to its high plasticity and large intraspecific divergence. Genome-wide mapping of expression quantitative trait loci (eQTLs) for 23 environmental adaptive genes was performed for 256 estuarine oysters. We identified 1194 eQTL single nucleotide polymorphisms (eSNPs), including 433 cis-eSNPs in four genes and 722 trans-eSNPs in eight genes. The expression variation explanation of cis-eSNPs (9.95%) was significantly higher than that of trans-eSNPs (9.15%). We specifically showed cis- and trans-eSNPs with high linkage disequilibrium (LD) for Traf7, Slc6a5, Ggt, and Dap3. For example, we identified a cis-regulatory LD block containing 68 cis-eSNP and a trans-regulatory LD block, including 20 trans-eSNPs in Traf7. A high proportion (85%) of 40 vital eSNPs exhibited significant G × E effects. We identified crossing and nonparallel interactions of G × E, with the tag cis-eSNPs of Baat and Slc6a5 as representatives. Our results indicated that cis-eQTLs are highly conserved. This study provides insights into the understanding of adaptive evolutionary mechanisms and phenotypic response prediction to variable environments, as well as the genetic improvement for superior adaptive traits for genetic resource conservation and aquaculture.

TRAF7-targeted HOXA5 acts as a tumor suppressor in prostate cancer progression and stemness via transcriptionally activating SPRY2 and regulating MEK/ERK signaling. Cell Death Discov 2023; 9:378. [PMID: 37845209 PMCID: PMC10579307 DOI: 10.1038/s41420-023-01675-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 09/23/2023] [Accepted: 10/03/2023] [Indexed: 10/18/2023] Open
Abstract
Homeobox A5 (HOXA5), a homeodomain transcription factor, is considered a tumor suppressor in cancer progression; however, its function in prostate cancer (PCa) remains unclear. This study focused on the relevance of HOXA5 in PCa progression. We identified the downregulation of HOXA5 in PCa tissues based on the TCGA database and further verified in 30-paired PCa and adjacent normal tissues. Functional studies revealed that HOXA5 upregulation impaired the stem-like characteristics and malignant behaviors of PCa cells in vitro and in vivo. Mechanistically, HOXA5 was found to be regulated by tumor necrosis factor receptor-associated factor 7 (TRAF7), a putative E3-ubiquitin ligase. We observed that TRAF7 was overexpressed in PCa and subsequently enhanced the degradation of HOXA5 protein via its ubiquitin ligase activity, contributing to the acquisition of an aggressive PCa phenotype. For its downstream mechanism, we demonstrated that sprouty RTK signaling antagonist 2 (SPRY2) served as a downstream target of HOXA5. HOXA5 could directly bind to the SPRY2 promoter, thereby regulating the SPRY2-mediated MEK/ERK signaling pathway. Silencing SPRY2 largely compromised the tumor-suppressive effect of HOXA5 in PCa progression and cancer stemness. Our findings highlight the previously-underappreciated signaling axis of TRAF7-HOXA5-SPRY2, which provides a novel prognostic and therapeutic target for PCa treatment.

TRAF7 is an essential regulator of blood vessel integrity during mouse embryonic and neonatal development. iScience 2023; 26:107474. [PMID: 37583551 PMCID: PMC10424150 DOI: 10.1016/j.isci.2023.107474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 05/19/2023] [Accepted: 07/21/2023] [Indexed: 08/17/2023] Open
Abstract
Targeted deletion of TRAF7 revealed that it is a crucial part of shear stress-responsive MEKK3-MEK5-ERK5 signaling pathway induced in endothelial cells by blood flow. Similar to Mekk3-, Mek5- or Erk5-deficient mice, Traf7-deficient embryos died in utero around midgestation due to impaired endothelium integrity. They displayed significantly lower expression of transcription factor Klf2, an essential regulator of vascular hemodynamic forces downstream of the MEKK3-MEK-ERK5 signaling pathway. In addition, deletion of Traf7 in endothelial cells of postnatal mice was associated with severe cerebral hemorrhage. Here, we show that besides MEKK3 and MEK5, TRAF7 associates with a planar cell polarity protein SCRIB. SCRIB binds with an N-terminal region of TRAF7, while MEKK3 associates with the C-terminal WD40 domain. Downregulation of TRAF7 as well as SCRIB inhibited fluid shear stress-induced phosphorylation of ERK5 in cultured endothelial cells. These findings suggest that TRAF7 and SCRIB may comprise an upstream part of the MEKK3-MEK5-ERK5 signaling pathway.

Abstract
Copy number variations regions (CNVRs) can be classified either as segregating, when found in both parents, and offspring, or non-segregating. A total of 65 segregating and 31 non-segregating CNVRs identified in at least 10 individuals within a dense pedigree of the Gochu Asturcelta pig breed was subjected to enrichment and functional annotation analyses to ascertain their functional independence and importance. Enrichment analyses allowed us to annotate 1018 and 351 candidate genes within the bounds of the segregating and non-segregating CNVRs, respectively. The information retrieved suggested that the candidate genes spanned by segregating and non-segregating CNVRs were functionally independent. Functional annotation analyses allowed us to identify nine different significantly enriched functional annotation clusters (ACs) in segregating CNVR candidate genes mainly involved in immunity and regulation of the cell cycle. Up to five significantly enriched ACs, mainly involved in reproduction and meat quality, were identified in non-segregating CNVRs. The current analysis fits with previous reports suggesting that segregating CNVRs would explain performance at the population level, whereas non-segregating CNVRs could explain between-individuals differences in performance.

Int J Mol Sci 2023; 24:ijms24098363. [PMID: 37176078 PMCID: PMC10179116 DOI: 10.3390/ijms24098363] [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: 03/30/2023] [Revised: 04/27/2023] [Accepted: 05/03/2023] [Indexed: 05/15/2023] Open
Abstract
The yellow catfish (Pelteobagrus fulvidraco) is an economic fish with a large breeding scale, and diseases have led to huge economic losses. Tumor necrosis factor receptor-associated factors (TRAFs) are a class of intracellular signal transduction proteins that play an important role in innate and adaptive immune responses by mediating NF-κB, JNK and MAPK signaling pathways. However, there are few studies on the TRAF gene family in yellow catfish. In this study, the open reading frame (ORF) sequences of TRAF1, TRAF2a, TRAF2b, TRAF3, TRAF4a, TRAF4b, TRAF5, TRAF6 and TRAF7 genes were cloned and identified in yellow catfish. The ORF sequences of the nine TRAF genes of yellow catfish (Pf_TRAF1-7) were 1413-2025 bp in length and encoded 470-674 amino acids. The predicted protein structures of Pf_TRAFs have typically conserved domains compared to mammals. The phylogenetic relationships showed that TRAF genes are conserved during evolution. Gene structure, motifs and syntenic analyses of TRAF genes showed that the exon-intron structure and conserved motifs of TRAF genes are diverse among seven vertebrate species, and the TRAF gene family is relatively conserved evolutionarily. Among them, TRAF1 is more closely related to TRAF2a and TRAF2b, and they may have evolved from a common ancestor. TRAF7 is quite different and distantly related to other TRAFs. Real-time quantitative PCR (qRT-PCR) results showed that all nine Pf_TRAF genes were constitutively expressed in 12 tissues of healthy yellow catfish, with higher mRNA expression levels in the gonad, spleen, brain and gill. After infection with Edwardsiella ictaluri, the expression levels of nine Pf_TRAF mRNAs were significantly changed in the head kidney, spleen, gill and brain tissues of yellow catfish, of which four genes were down-regulated and one gene was up-regulated in the head kidney; four genes were up-regulated and four genes were down-regulated in the spleen; two genes were down-regulated, one gene was up-regulated, and one gene was up-regulated and then down-regulated in the gill; one gene was up-regulated, one gene was down-regulated, and four genes were down-regulated and then up-regulated in the brain. These results indicate that Pf_TRAF genes might be involved in the immune response against bacterial infection. Subcellular localization results showed that all nine Pf_TRAFs were found localized in the cytoplasm, and Pf_TRAF2a, Pf_TRAF3 and Pf_TRAF4a could also be localized in the nucleus, uncovering that the subcellular localization of TRAF protein may be closely related to its structure and function in cellular mechanism. The results of this study suggest that the Pf_TRAF gene family plays important roles in the immune response against pathogen invasion and will provide basic information to further understand the roles of TRAF gene against bacterial infection in yellow catfish.

Abstract
TANK-binding kinase 1 (TBK1) is a nodal protein involved in multiple signal transduction pathways. In RNA virus-mediated innate immunity, TBK1 is recruited to the prion-like platform formed by MAVS and subsequently activates the transcription factors IRF3/7 and NF-κB to produce type I interferon (IFN) and proinflammatory cytokines for the signaling cascade. In this study, TRAF7 was identified as a negative regulator of innate immune signaling. TRAF7 interacts with TBK1 and promotes K48-linked polyubiquitination and degradation of TBK1 through its RING domain, impairing the activation of IRF3 and the production of IFN-β. In addition, we found that the conserved cysteine residues at position 131 of TRAF7 are necessary for its function toward TBK1. Knockout of TRAF7 could facilitate the activation of IRF3 and increase the transcript levels of downstream antiviral genes. These data suggest that TRAF7 negatively regulates innate antiviral immunity by promoting the K48-linked ubiquitination of TBK1.

Abstract
N6-methyladenosine (m6A) is a dynamic posttranscriptional RNA modification that plays an important role in determining transcript fate. The functional consequence of m6A deposition is dictated by a group of host proteins that specifically recognize and bind the m6A modification, leading to changes in RNA stability, transport, splicing, or translation. The cellular m6A methylome undergoes changes during certain pathogenic conditions such as viral infections. However, how m6A modification of host cell transcripts and noncoding RNAs change during severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection has not been reported. Here, we define the epitranscriptomic m6A profile of SARS-CoV-2-infected human lung epithelial cells compared to uninfected controls. We identified mRNA and long and small noncoding RNA species that are differentially m6A modified in response to SARS-CoV-2 infection. The most significantly differentially methylated transcript was the precursor of microRNA-4486 (miRNA-4486), which showed significant increases in abundance and percentage of methylated transcripts in infected cells. Pathway analyses revealed that differentially methylated transcripts were significantly associated with several cancer-related pathways, protein processing in the endoplasmic reticulum, cell death, and proliferation. Upstream regulators predicted to be associated with the proteins encoded by differentially methylated mRNAs include several proteins involved in the type-I interferon response, inflammation, and cytokine signaling. IMPORTANCE Posttranscriptional modification of viral and cellular RNA by N6-methyladenosine (m6A) plays an important role in regulating the replication of many viruses and the cellular immune response to infection. We therefore sought to define the epitranscriptomic m6A profile of human lung epithelial cells infected with SARS-CoV-2. Our analyses demonstrate the differential methylation of both coding and noncoding cellular RNAs in SARS-CoV-2-infected cells compared to uninfected controls. Pathway analyses revealed that several of these RNAs may be involved in the cellular response to infection, such as type-I interferon. Our study implicates m6A modification of infected-cell RNA as a mechanism of posttranscriptional gene regulation during SARS-CoV-2 infection.

Abstract
Tumor necrosis factor receptor-associated factors (TRAFs) are signaling mediators for Toll-like receptor (TLR) and tumor necrosis factor (TNFR) superfamily that play important roles in organism immune response. However, reports on systematic identification of TRAF gene family in teleost fish and the function of TRAFs in innate immunity of black rockfish (Sebastes schlegelii) are lacked. In our study, eight TRAF genes were identified and characterized, namely, SsTRAF2a, SsTRAF2a-like, SsTRAF2b, SsTRAF3, SsTRAF4, SsTRAF5, SsTRAF6 and SsTRAF7 in S. schegelii. Furthermore, we analyzed their sequences, conserved domains, gene structures, motif compositions, phylogeny, tissue expression patterns in healthy and Vibro. anguillarum challenged individuals. All the SsTRAFs contained typical conserved domain, including C-terminal MATH domain and N-terminal RING finger domain. Analyses of gene structures and motifs showed the distribution of exon-intron and conserved motifs in S. schegelii and serval other teleost fish. We also analyzed the expression file of SsTRAFs in five immune-relate organs, liver, spleen, kidney, gill and intestine in healthy and bacterial challenged fish. The results indicated that all SsTRAF member were widely involved in immune response after pathogenic bacteria infection. In summary, the analyses of TRAFs in S. schegelii will be helpful to better understand the diverse roles of TRAF genes in the innate immune response to bacterial challenge.

Abstract
BACKGROUND
In the past decade, next-generation sequencing has spurred significant progress in the understanding of cytogenetic alterations that occur in meningiomas. Eighty percent of adult meningiomas harbor pathogenic somatic variants involving NF2, TRAF7, SMARCB1, KLF4, PI3K, or POLR2A. Somatic variants in TRAF7 associated with meningiomas usually localize to the gene’s WD40 domains but are mutually exclusive to germline mutations, which cause a distinctive autosomal dominant syndrome.
OBSERVATIONS
This case involved a 15-year-old girl with bilateral optic nerve sheath meningiomas, diffuse meningiomatosis, and syndromic features, including craniosynostosis, brain anomalies, syndactyly, brachydactyly, epicanthus, and patent ductus arteriosus. Genetic testing of the meningioma specimen 7 years after biopsy showed a pathogenic p.R641C variant within the WD40 domain of the TRAF7 gene. Additional testing of unaffected tissues identified the same variant at lower allele frequencies, consistent with postzygotic somatic mosaicism.
LESSONS
The authors report postzygotic somatic mosaicism for a p.R641C variant in the TRAF7 gene in a patient with bilateral optic nerve sheath meningiomas, diffuse meningiomatosis and a constellation of systemic findings previously recognized in patients with germline mutations of this gene. This is the first report of optic nerve sheath meningioma in a patient with mutation in the TRAF7 gene.

Abstract
Craniosynostosis is a condition of premature fusion of the cranial sutures. Multi-suture craniosynostosis has been found to be associated with a number of syndromes and underlying gene mutations. Tumour necrosis factor receptor-associated factors (TRAFs) are a family of adaptor proteins interacting with cell surface receptors or other signalling molecules. TRAF7 is one of the factors involved in multiple biologic processes, including ubiquitination, myogenesis and toll-like receptor signalling. Here, we report a child who presented with multi-suture craniosynostosis and had the uncommon c.1570C>T (p.Arg524Trp) variant of TRAF7.

Abstract
TNF receptor associated factors (TRAFs) represent a family of cytoplasmic signaling adaptor proteins that regulate, bundle, and transduce inflammatory signals downstream of TNF- (TNF-Rs), interleukin (IL)-1-, Toll-like- (TLRs), and IL-17 receptors. TRAFs play a pivotal role in regulating cell survival and immune cell function and are fundamental regulators of acute and chronic inflammation. Lately, the inhibition of inflammation by anti-cytokine therapy has emerged as novel treatment strategy in patients with atherosclerosis. Likewise, growing evidence from preclinical experiments proposes TRAFs as potent modulators of inflammation in atherosclerosis and vascular inflammation. Yet, TRAFs show a highly complex interplay between different TRAF-family members with partially opposing and overlapping functions that are determined by the level of cellular expression, concomitant signaling events, and the context of the disease. Therefore, inhibition of specific TRAFs may be beneficial in one condition and harmful in others. Here, we carefully discuss the cellular expression and signaling events of TRAFs and evaluate their role in vascular inflammation and atherosclerosis. We also highlight metabolic effects of TRAFs and discuss the development of TRAF-based therapeutics in the future.

Abstract
Neuronal death and neuroinflammation play critical roles in regulating the progression of traumatic brain injury (TBI). However, associated pathogenesis has not been fully understood. Tumor necrosis factor receptor-associated factor 7 (TRAF7), as the unique noncanonical member of the TRAF family, mediates various essential biological processes. Nevertheless, the effects of TRAF7 on TBI are still unclear. In this study, we showed that TRAF7 expression was markedly up-regulated in cortex and hippocampus of mice after TBI. Brain-specific TRAF7 deletion markedly ameliorated neuronal death in cortical and hippocampal samples of TBI mice, accompanied with cognitive impairments and motor dysfunction. Moreover, the aberrant activation of astrocyte and microglia in cortex and hippocampus of TBI mice was significantly restrained by TRAF7 conditional knockout in brain, as indicated by the increased expression of GFAP and Iba1. In addition, the releases of pro-inflammatory factors caused by TBI were also considerably diminished by brain-specific TRAF7 knockout, which were largely through the blockage of nuclear factor-κB (NF-κB) and mitogen-activated protein kinases (MAPKs) signaling pathways. Importantly, mitogen-activated protein kinase kinase kinase 3 (MEKK3) expression levels were greatly enhanced in cortex and hippocampus of mice with TBI, while being dramatically ameliorated by TRAF7 knockout in brain. Mechanistically, we showed that TRAF7 directly interacted with MEKK3. Of note, MEKK3 over-expression almost abrogated the capacity of TRAF7 knockout to mitigate neuronal death and neuroinflammation in the isolated primary cortical neurons and glial cells upon oxygen-glucose-deprivation/reperfusion (OGD/R) stimulation. Collectively, TRAF7 may be an important molecular switch that leads to TBI in a MEKK3-dependent manner, and can be served as a therapeutic target for TBI treatment.

Abstract
Vascular permeability is regulated mainly by the endothelial barrier and controls vascular homeostasis, proper vessel development, and immune cell trafficking. Several molecules are involved in regulating endothelial barrier function. Roundabout 4 (Robo4) is a single-pass transmembrane protein that is specifically expressed in vascular endothelial cells. Robo4 is an important regulator of vascular leakage and angiogenesis, especially under pathological conditions. The role of Robo4 in preventing vascular leakage has been studied in various disease models, including animal models of retinopathy, tumors, diabetes, and endotoxemia. The involvement of Robo4 in vascular endothelial growth factor and inflammation-mediated signaling pathways has been well studied, and recent evidence suggests that Robo4 modulates endothelial barrier function via distinct mechanisms. In this review, we discuss the role of Robo4 in endothelial barrier function and the underlying molecular mechanisms.

Abstract
Germline variants in tumor necrosis factor receptor-associated factor 7 (TRAF7) gene have recently been described in about 50 patients with developmental delay and cardiac, facial, and digital anomalies (CAFDADD). We aimed to depict further the clinical and genetic spectrum associated with TRAF7 germline variants in two additional patients, broaden the mutational spectrum, and support the characteristic clinical variety to facilitate the diagnostics of the syndrome among physician involved in the evaluation of patients with developmental delay/congenital malformations.

Type of bony involvement predicts genomic subgroup in sphenoid wing meningiomas. J Neurooncol 2021; 154:237-246.

Abstract
PURPOSE As sphenoid wing meningiomas (SWMs) are associated with varying degrees of bony involvement, we sought to understand potential relationships between genomic subgroup and this feature. METHODS Patients treated at Yale-New Haven Hospital for SWM were reviewed. Genomic subgroup was determined via whole exome sequencing, while the extent of bony involvement was radiographically classified as no bone invasion (Type I), hyperostosis only (Type II), tumor invasion only (Type III), or both hyperostosis and tumor invasion (Type IV). Among additional clinical variables collected, a subset of tumors was identified as spheno-orbital meningiomas (SOMs). Machine-learning approaches were used to predict genomic subgroups based on pre-operative clinical features. RESULTS Among 64 SWMs, 53% had Type-II, 9% had Type-III, and 14% had Type-IV bone involvement; nine SOMs were identified. Tumors with invasion (i.e., Type III or IV) were more likely to be WHO grade II (p: 0.028). Additionally, tumors with invasion were nearly 30 times more likely to harbor NF2 mutations (OR 27.6; p: 0.004), while hyperostosis only were over 4 times more likely to have a TRAF7 mutation (OR 4.5; p: 0.023). SOMs were a significant predictor of underlying TRAF7 mutation (OR 10.21; p: 0.004). CONCLUSIONS SWMs with invasion into bone tend to be higher grade and are more likely to be NF2 mutated, while SOMs and those with hyperostosis are associated with TRAF7 variants. Pre-operative prediction of molecular subtypes based on radiographic bony characteristics may have significant biological and clinical implications based on known recurrence patterns associated with genomic drivers and grade.

Abstract
Tumor necrosis factor receptor-associated factor 5 (TRAF5) is an intracellular protein that binds to the cytoplasmic portion of tumor necrosis factor receptors and mediates the activation of downstream nuclear factor-kappa B (NF-κB), interferon regulatory factor 3, and mitogen activated protein kinase signaling pathways. Compared with other TRAF proteins, TRAF5 is largely unknown in teleosts. In the present study, a TRAF5 homologue (HgTRAF5) from the hybrid grouper (Epinephelus fuscoguttatus♂ × Epinephelus lanceolatus♀) was cloned and characterized. The open reading frame of HgTRAF5 consists of 1743 nucleotides encoding a 581 amino acid protein with a predicted molecular mass of 64.90 kDa. Similar to its mammalian counterpart, HgTRAF5 contains an N-terminal RING finger domain, a zinc finger domain, and a C-terminal TRAF domain, including a coiled-coil domain and a MATH domain. HgTRAF5 shares 99.83% identity with giant grouper (Epinephelus lanceolatus) TRAF5. Quantitative real-time PCR analysis indicated that HgTRAF5 mRNA was broadly expressed in all examined tissues. The expression of HgTRAF5 increased after Singapore grouper iridovirus (SGIV) infection in grouper spleen (GS) cells. Intracellular localization analysis demonstrated that the full-length HgTRAF5 protein mainly distributed in the cytoplasm. HgTRAF5 overexpression also promoted SGIV replication during viral infection in vitro. HgTRAF5 significantly promoted the activities of interferon-β, interferon-sensitive response element, and NF-κB. Taken together, these results are important for a better understanding of the function of TRAF5 in fish and reveal its involvement in the host response to immune challenge by SGIV.

Abstract
Meningiomas are the most common benign brain tumors. Mutations of the E3 ubiquitin ligase TRAF7 occur in 25% of meningiomas and commonly cooccur with mutations in KLF4, yet the functional link between TRAF7 and KLF4 mutations remains unclear. By generating an in vitro meningioma model derived from primary meningeal cells, we elucidated the cooperative interactions that promote meningioma development. By integrating TRAF7-driven ubiquitinome and proteome alterations in meningeal cells and the TRAF7 interactome, we identified TRAF7 as a proteostatic regulator of RAS-related small GTPases. Meningioma-associated TRAF7 mutations disrupted either its catalytic activity or its interaction with RAS GTPases. TRAF7 loss in meningeal cells altered actin dynamics and promoted anchorage-independent growth by inducing CDC42 and RAS signaling. TRAF deficiency-driven activation of the RAS/MAPK pathway promoted KLF4-dependent transcription that led to upregulation of the tumor-suppressive Semaphorin pathway, a negative regulator of small GTPases. KLF4 loss of function disrupted this negative feedback loop and enhanced mutant TRAF7-mediated cell transformation. Overall, this study provides new mechanistic insights into meningioma development, which could lead to novel treatment strategies. SIGNIFICANCE: The intricate molecular cross-talk between the ubiquitin ligase TRAF7 and the transcription factor KLF4 provides a first step toward the identification of new therapies for patients with meningioma.

Abstract
Tumor necrosis factor receptor-associated factors (TRAFs) play important roles in the biological processes of immune regulation, the inflammatory response, and apoptosis. TRAF4 belongs to the TRAF family and plays a major role in many biological processes. Compared with other TRAF proteins, the functions of TRAF4 in teleosts have been largely unknown. In the present study, the TRAF4 homologue (EcTRAF4) of the orange-spotted grouper was characterized. EcTRAF4 consisted of 1413 bp encoding a 471-amino-acid protein, and the predicted molecular mass was 54.27 kDa. EcTRAF4 shares 99.79% of its identity with TRAF4 of the giant grouper (E. lanceolatus). EcTRAF4 transcripts were ubiquitously and differentially expressed in all the examined tissues. EcTRAF4 expression in GS cells was significantly upregulated after stimulation with red-spotted grouper nervous necrosis virus (RGNNV). EcTRAF4 protein was distributed in the cytoplasm of GS cells. Overexpressed EcTRAF4 promoted RGNNV replication during viral infection in vitro. Yeast two-hybrid and coimmunoprecipitation assays showed that EcTRAF4 interacted with the coat protein (CP) of RGNNV. EcTRAF4 inhibited the activation of IFN3, IFN-stimulated response element (ISRE), and nuclear factor-κB (NF-κB). Overexpressed EcTRAF4 also reduced the expression of interferon (IFN)-related molecules and pro-inflammatory factors. Together, these results demonstrate that EcTRAF4 plays crucial roles in RGNNV infection.

Abstract
Comprehensive genomic studies of meningioma have offered important insights about the molecular mechanisms underlying this common brain tumor. The use of next-generation sequencing techniques has identified driver mutations in approximately 80% of benign sporadic lesions, as well as epigenetic, regulatory, and copy number events that are associated with formation and disease progression. The events described to date fall into five mutually exclusive molecular subgroups that correlate with tumor location and embryological origin. Importantly, these subgroups also carry implications for clinical management, as they are predictive of histologic subtype and the likelihood of progression. Further work is necessary to understand the molecular mechanisms by which identified mutations drive tumorigenesis as well as the genomic pathways that transform benign lesions into malignancies. Progress made during the past decade has opened the door to potential molecular therapies as well as integration of meningioma genotyping data into clinical management decisions. Several pharmacologic trials are currently underway that leverage recent genomic findings to target established oncogenic pathways in refractory tumors. With the combined efforts of physicians and basic science investigators, the clinical management of meningioma will continue to make important strides in the coming years.

Abstract
Meningiomas are a heterogeneous group of tumors, defined histo-pathologically by World Health Organization (WHO) grading. The WHO grade of meningiomas does not always correlate with clinical aggressiveness. Despite maximal surgical resection and adjuvant radiation, a subset of tumors are clinically aggressive; displaying early recurrence and invasion. Current methods for identifying aggressive meningiomas solely focus on genomics, proteomics, or epigenetics and not a combination of all for developing a real-time clinical biomarker. Improved methods for the identification of these outlying tumors can facilitate better classification and potentially adjuvant treatment planning. Understanding the pathways of oncogenesis using multiple markers driving aggressive meningiomas can provide a foundation for targeted therapies, which currently do not exist.

Abstract
The TRAF family member-associated nuclear factor (NF)-κB activator (TANK) was first identified as a TRAF-binding protein with both stimulatory and inhibitory properties in host innate immune activation. To elucidate the roles of TANK in teleosts, we cloned and characterized the TANK homologue of orange-spotted grouper (Epinephelus coioides). The open reading frame (ORF) of EcTANK consists of 1026 nucleotides encoding a 342 amino acid protein with a predicted molecular mass of 38.24 kDa. EcTANK shares 89.47% and 88.89% identity with Larimichthys crocea TANK and Lates calcarifer TANK, respectively. EcTANK was distributed in all 11 examined tissues. The expression of EcTANK in the spleen increased after infection with Singapore grouper iridovirus (SGIV) and red-spotted grouper nervous necrosis virus (RGNNV). EcTANK was mainly located in the cytoplasm of grouper spleen cells. EcTANK enhanced SGIV and RGNNV replication during viral infection in vitro. Overexpression EcTANK decreased the expression levels of interferon-associated cytokines and pro-inflammatory factors, and enhanced activation of NF-κB. Taken together, these results suggest that EcTANK may play an important role in antiviral innate immune activation in grouper.

Abstract
Tumor necrosis factor receptor-associated factor 3 (TRAF3) is a multifunctional adaptor protein primarily involved in both bacterial defense and antiviral immunity in living organisms. However, the knowledge on TRAF3 in blunt snout bream (Megalobrama amblycephala), a freshwater fish with economic values, remained unclear. In the present study, we identified and characterized successfully Traf3 gene from M. amblycephala (maTraf3). The maTraf3 cDNA contained a 1722 bp open reading frame that encoded a protein of 573 amino acid residues. The deduced amino acid sequence comprised of a RING finger domain, two zinc finger motifs, a coiled-coil region and a MATH domain. Analysis of the transcriptional patterns of maTraf3 revealed that it was ubiquitously distributed in various tissues tested from M. amblycephala, with the abundance of expression in spleen and muscle. Following a challenge with Aeromonas hydrophila and lipopolysaccharide stimulation, the expression of maTraf3 was strongly enhanced at different time points in vitro and in vivo. MaTRAF3 was identified as a cytosolic protein and suggested to form aggregates or be associated with vesicles scattering in the cytoplasm. NF-κB transcription was activated by maTraf3 in reporter assay. The overexpression of maTraf3 produced high levels of pro-inflammatory cytokines such as IL-1β, IL-6, IL-8 and TNF-α, implying its immune-regulatory role in M. amblycephala. Taken together, our results obtained in this study demonstrated the crucial role of maTraf3 in mediating host innate immune response to pathogen invasion via NF-κB signaling pathway, which might indicate a novel therapeutic approach to combat bacterial infection in fish.

Abstract
Meningiomas are the most common primary intracranial neoplasm. The current World Health Organization (WHO) classification categorizes meningiomas based on histopathological features, but emerging molecular data demonstrate the importance of genomic and epigenomic factors in the clinical behavior of these tumors. Treatment options for symptomatic meningiomas are limited to surgical resection where possible and adjuvant radiation therapy for tumors with concerning histopathological features or recurrent disease. At present, alternative adjuvant treatment options are not available in part due to limited historical biological analysis and clinical trial investigation on meningiomas. With advances in molecular and genomic techniques in the last decade, we have witnessed a surge of interest in understanding the genomic and epigenomic landscape of meningiomas. The field is now at the stage to adopt this molecular knowledge to refine meningioma classification and introduce molecular algorithms that can guide prediction and therapeutics for this tumor type. Animal models that recapitulate meningiomas faithfully are in critical need to test new therapeutics to facilitate rapid-cycle translation to clinical trials. Here we review the most up-to-date knowledge of molecular alterations that provide insight into meningioma behavior and are ready for application to clinical trial investigation, and highlight the landscape of available preclinical models in meningiomas.

Molecular characterization and functional analysis of tumor necrosis factor receptor-associated factor 2/7 and tumor necrosis factor receptor 1-associated death domain protein from Larimichthys crocea. FISH & SHELLFISH IMMUNOLOGY 2020; 103:385-402. [PMID: 32387478 DOI: 10.1016/j.fsi.2020.04.027] [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: 12/18/2019] [Revised: 04/07/2020] [Accepted: 04/13/2020] [Indexed: 06/11/2023]
Abstract
In the present study, we characterized tumor necrosis factor receptor-associated factor 2/7 (lcTRAF2/7) and TNFR1-associated death domain protein (lcTRADD) in Larimichthys crocea (L. crocea) and examined their expression profiles in tissues of Vibrio-challenged and unchallenged fish. The coding sequences of lcTRAF2, lcTRAF7, and lcTRADD were 1488, 2454, and 744 nucleotides, and they encoded proteins of 495, 344, and 248 amino acids, respectively. The results of phylogenetic analysis revealed that lcTRAF2, lcTRAF7, and lcTRADD were closest to Oplegnathus fasciatus (85%), Xiphophorus maculatus (97%), and Acanthochromis polyacanthus (65%), respectively. Multiple sequence alignment showed that lcTRAF2 and lcTRAF7 were highly conserved with other vertebrate TRAFs in their functional domains; however, lcTRADD was poorly conserved. The results of quantitative real-time polymerase chain reaction analysis indicated that lcTRAF2, lcTRAF7, and lcTRADD were constitutively expressed in the spleen, liver, kidney, heart, brain, gill, bladder, skin, fin, eye, and muscle. After challenging fish with Vibrio parahaemolyticus, the mRNA expression levels of lcTRAF2, lcTRAF7, and lcTRADD were upregulated in liver, spleen, and kidney. Immunofluorescence staining revealed that lcTRAF2 and lcTRADD were cytoplasmic in localization, whereas lcTRAF7 targeted both the cytoplasm and nucleus. In addition, the NF-κB protein level was upregulated after lipopolysaccharide stimulation in lcTRAF2, lcTRAF7, or lcTRADD overexpressing cells. Taken collectively, these results have improved our understanding of the functions of TRAF2, TRAF7, and TRADD in pathogenic infections in teleosts.

Abstract
Tumour necrosis factor receptor-associated factors (TRAFs) are key regulatory proteins in the NF-κB signaling pathways. TRAF2 participates in the activation of both canonical and non-canonical NF-κB pathways, which are crucial for cell inflammation and cell survival. To elucidate its function in teleost fish, TRAF2 homologues of yellow grouper (Epinephelus awoara) and golden pompano (Trachinotus ovatus) have been cloned and characterized in this study. The open reading frame (ORF) of grouper TRAF2 (EaTRAF2) consists of 1563 nucleotides encoding a 521 amino acid protein with a predicted molecular mass of 58.70 kDa. The ORF of golden pompano TRAF2 (ToTRAF2) consists of 1563 nucleotides encoding a 521 amino acid protein with a predicted molecular mass of 58.66 kDa EaTRAF2 and ToTRAF2 share 99.23% and 99.42% identity with orange-spotted grouper (Epinephelus coioides) TRAF2 (EcTRAF2), respectively. Quantitative real-time PCR analysis indicated that the expression of EaTRAF2 was increased in grouper spleen (GS) cells after Red-spotted grouper nervous necrosis virus (RGNNV) infection; while the expression of ToTRAF2 was decreased in golden pompano brain (TOGB) cells after RGNNV infection. Both EaTRAF2 and ToTRAF2 were identified as a cytosolic protein and suggested to be associated with vesicles scattering in the cytoplasm. Both EaTRAF2 and ToTRAF2 enhanced RGNNV replication during viral infection in vitro. Further studies showed that EaTRAF2 and ToTRAF2 overexpression decreased the expression levels of interferon associated cytokines and pro-inflammatory factors. Taken together, these results are important for better understanding of the function of TRAF2 in fish and reveal its involvement in host response to immune challenges in RGNNV.

Abstract
Tumor necrosis factor receptor (TNFR)-associated factors (TRAFs) are a family of crucial signaling molecules that mediate the signal transduction of various immune signaling pathways. Extensive studies have demonstrated that TRAFs play vital roles in regulating cellular immune responses. However, the biological functions and expression profiling of TRAFs in Chinese soft-shelled turtle (Pelodiscus sinensis) remain unclear. In this study, the genes of the PsTRAF family at the genome-wide level were identified in P. sinensis, revealing six PsTRAF members that contained the conserved TRAF domain in the C-terminal regions. Molecular evolutionary analysis showed that PsTRAFs shared close evolutionary relationships and similar protein crystal structures with the TRAF homologs from other turtles, indicating the evolutionary conservation of PsTRAFs. Further expression analysis revealed the tissue-specific expression of PsTRAF genes. Obvious variations in the expression of PsTRAF genes were observed in the spleen in response to Aeromonas hydrophila infection. Three PsTRAF genes, PsTRAF2, PsTRAF3, and PsTRAF6, were significantly upregulated at the mRNA and protein levels post-infection, indicating their potential function in the immune response. Moreover, the protein-protein associations of PsTRAFs with several signaling receptors were predicted in P. sinensis. These results provide a basis for the investigation of the functional roles of PsTRAFs in immune defense against bacterial infection.

Abstract
BACKGROUND Several somatic mutations in TRAF7 have been reported in cancers, whereas a few germline heterozygous mutations have been recently linked to a neurodevelopmental disorder, characterized by craniofacial dysmorphisms, congenital heart defects, and digital anomalies. CASES We report two subjects harboring de novo heterozygous missense variants in TRAF7, namely the recurrent 1964G>A(p.Arg655Gln) and the novel missense c.1204C>G(p.Leu402Val) variants. In addition to the typical hallmarks of the TRAF7-related disorder, both subjects presented with a recognizable "pear-shaped" skull due to multiple craniosynostosis, sinus pericranii, skull base/cranio-cervical junction anomalies, dysgyria, and inferior cerebellar vermis hypoplasia. CONCLUSIONS Hence, we expand the genotypic and phenotypic spectrum of this neurodevelopmental disorder, discussing possible implications for clinical management of subjects with germline TRAF7 mutations.

Abstract
As a member of tumor necrosis factor receptor (TNFR)-associated factor (TRAF) family, TRAF3 is an important regulator of NF-κB and type I interferon (IFN) activation, especially in Toll-like receptors (TLRs)- and retinoic acid inducible gene I (RIG-I)-like receptors (RLRs)-mediated signaling pathway. In the present study, a TRAF3 homologue named Lc-TRAF3 was characterized in large yellow croaker (Larimichthys crocea). The open reading frame (ORF) of Lc-TRAF3 contains 1788 bp encoding a protein of 595 amino acids (aa). Sequence analysis indicated that Lc-TRAF3 is conserved in vertebrates, constituted with a N-terminal RING finger, two TRAF-type zinc fingers, and a C-terminal TRAF-MATH domain. The genome organization of Lc-TRAF3 is conserved in fish, with 13 exons and 12 introns, but different from that in birds or mammals, which contains 10 exons and 9 introns. Lc-TRAF3 was identified as cytosolic protein base on fluorescence microscopy analysis. Expression analysis revealed that Lc-TRAF3 was broadly distributed in examined organs/tissues, with the highest expression level in gill and weakest in brain, and could be up-regulated under poly I:C, LPS, PGN, and Pseudomonas plecoglossicida stimulation in vivo. Interestingly, overexpression Lc-TRAF3 could induce the activation of NF-κB, and Lc-TRAF3 co-transfected with Lc-TRIF induced a significantly higher level of NF-κB and IRF3 promoter activity, implying that Lc-TRAF3 may function as an enhancer in Lc-TRIF-mediated signaling pathway.

Abstract
Cyclic-di-AMP (c-di-AMP) is a bacterial second messenger that is produced by intracellular bacterial pathogens in mammalian host macrophages. Previous reports have shown that c-di-AMP is recognized by intracellular pattern recognition receptors of the innate immune system and stimulate type I interferon response. Here we report that the response to c-di-AMP includes a post-transcriptional component that is involved in the induction of additional inflammatory cytokines including IL-6, CXCL2, CCL3, and CCL4. Their mRNAs contain AU-rich elements (AREs) in their 3' UTR that promote decay and repress translation. We show that c-di-AMP leads to the phosphorylation of p38 MAPK as well as the induction of the ARE-binding protein TTP, both of which are components of a signaling pathway that modulate the expression of ARE-containing mRNAs at the post-transcriptional level. Pharmacological inhibition of p38 reduces the c-di-AMP-dependent release of induced cytokines, while TTP knockdown increases their release and mRNA stability. C-di-AMP can specifically increase the expression of a nano-Luciferase reporter that contains AREs. We propose a non-canonical intracellular mode of activation of the p38 MAPK pathway with the subsequent enhancement in the expression of inflammatory cytokines. C-di-AMP is widely distributed in bacteria, including infectious intracellular pathogens; hence, understanding of its post-transcriptional gene regulatory effect on the host response may provide novel approaches for therapy.

Abstract
Tumor necrosis factor (TNF) receptor-associated factors (TRAFs) play crucial roles as signaling mediators for the TNF receptor (TNFR) superfamily and the interleukin-1 receptor/Toll-like receptor (IL-1R/TLR) superfamily. TRAFs collectively play important roles in multiple biological processes and organismal immunity. However, systematic identification of the TRAF gene family in teleost fish has not yet been reported, and there is little available information about its roles in innate immunity in Chinese tongue sole (Cynoglossus semilaevis), an aquaculture fish of high economic value. In the present study, we identified and characterized seven TRAF genes, namely, CsTRAF2a, CsTRAF2b, CsTRAF3, CsTRAF4, CsTRAF5, CsTRAF6 and CsTRAF7, in Chinese tongue sole, and the complete ORFs of the CsTRAFs were cloned. Sequence analysis revealed various genomic structures of the CsTRAFs and showed that they contain typical conserved domains compared with mammalian TRAFs. Phylogenetic analysis indicated the evolutionary relationships of TRAF family members in teleost fish and revealed an absence of TRAF1 in most species and TRAF5 in some species of teleosts. Analysis of the gene structures and motifs showed the diversity and distribution of exon-intron structures and conserved motifs in Chinese tongue sole and several other teleost species. Real-time quantitative PCR was used to investigate the expression patterns of CsTRAF genes in tissues of healthy fish and in the gills, livers and spleens of fish after bacterial infection with Vibrio harveyi. The results indicate that only CsTRAF2a is relatively highly expressed in the brain and that the other CsTRAFs are highly expressed in immune-related tissues and may participate in the immune response after infection with pathogenic bacteria. Functional analysis of CsTRAF3, CsTRAF4 and CsTRAF6 revealed that only CsTRAF6 could strongly activate the NF-кB pathway after overexpression of CsTRAF3, CsTRAF4 and CsTRAF6 in HEK-293T cells. This systematic analysis provided valuable information about the diverse roles of TRAFs in the innate immune response to pathogenic bacterial infection in teleost fish and will contribute to the functional characterization of CsTRAF genes in further research.

Bin W, Ming X, Wen-Xia C. TRAF1 meditates lipopolysaccharide-induced acute lung injury by up regulating JNK activation. Biochem Biophys Res Commun 2019; 511:49-56. [PMID: 30760405 DOI: 10.1016/j.bbrc.2019.01.041] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2018] [Accepted: 01/08/2019] [Indexed: 01/11/2023]
Abstract
Acute lung injury (ALI) is served as a severe life-threatening disease. However, the pathogenesis that contributes to ALI has not been fully understood. Tumor necrosis factor receptor-associated factor 1 (TRAF1) interacts with multiple regulators, performing its diverse role in biological functions. However, the effects of TRAF1 on ALI remain unknown. In this study, we attempted to explore the role of TRAF1 in ALI progression. The findings suggested that TRAF1-knockout (KO) markedly attenuated LPS-induced severe mortality rate in murine animals. LPS-elicited histological alterations in pulmonary tissues were significantly alleviated by TRAF1-deletion. Additionally, TRAF1 knockout effectively attenuated lung injury, as evidenced by the reduced lung wet/dry (W/D) weight ratio, as well as decreased bronchoalveolar lavage fluid (BALF) protein levels and neutrophil infiltration. Meanwhile, TRAF1 deletion markedly lessened inflammation, oxidative stress and apoptosis in BALF and/or lung tissues. The levels of pro-inflammatory cytokines stimulated by LPS were down-regulated by TRAF1 ablation, along with the inactivation of nuclear factor κB (NF-κB). LPS-promoted reactive oxygen species (ROS) generation was decreased in TRAF1-KO mice, partly through the improvement of anti-oxidants. Apoptosis was also inhibited by TRAF1 deletion in lung tissues of LPS-challenged mice through the suppression of cleaved Caspase-3. Moreover, TRAF1 knockout significantly decreased c-Jun N-terminal kinase (JNK) activation and its down-streaming signal of c-Jun in pulmonary samples of LPS-induced mice. Importantly, the in vitro study suggested that promoting JNK activation markedly abrogated TRAF1 knockdown-attenuated inflammation, ROS production and apoptosis in LPS-exposed A549 cells. Therefore, our experimental results provided evidence that TRAF1 suppression effectively protected LPS-induced ALI against inflammation, oxidative stress and apoptosis through the suppression of JNK activity.

Abstract
The large yellow croaker (Larimichthys crocea) has a well-developed innate immune system. To gain a better understanding of the defense mechanisms involved in this system, we studied tumor necrosis factor receptor-associated factors (TRAFs), which play important roles in the Toll-like receptor (TLR) pathway. We characterized the full-length open reading frames and protein structures of TRAF3 and TRAF6 to determine their identities, and conducted phylogenetic analysis to determine their evolutionary relationships. To assess the roles of TRAFs in innate immune responses in the large yellow croaker, we performed quantitative reverse-transcription PCR (qRT-PCR) to characterize expression profiles in a range of tissues at different stages after challenge with polyinosinic polycytidylic acid (poly I:C) and Vibrio anguillarum. Following poly I:C challenge, the expression levels of TRAF3 and TRAF6 were highest in the kidneys and lowest in the spleen, whereas after infection with V. anguillarum, TRAF6 expression was the highest in the kidneys and lowest in the liver.

Tumor necrosis factor receptor-associated factor 6 is required to inhibit foreign body giant cell formation and activate osteoclasts under inflammatory and infectious conditions. J Bone Miner Metab 2018; 36:679-690.

Abstract
Osteoclasts and foreign body giant cells (FBGCs) are derived from common progenitors and share properties such as multi-nucleation capacity induced by cell-cell fusion; however, mechanisms underlying lineage determination between these cells remain unclear. Here we show that, under inflammatory conditions, osteoclasts are stimulated in a manner similar to M1 macrophages, while formation of FBGCs, which exhibit M2-like phenotypes, is inhibited in a manner similar to that seen in M1/M2 macrophage polarization. FBGC/osteoclast polarization was inhibited by conditional knockout of tumor necrosis factor receptor associated factor 6 (Traf6) in adults in vivo and in vitro. Traf6-null mice were previously reported to die soon after birth, but we found that Traf6 deletion in adults did not cause lethality but rather inhibited osteoclast activation and prevented FBGC inhibition under inflammatory conditions. Accordingly, basal osteoclastogenesis was significantly inhibited by Traf6 deletion in vivo and in vitro and accompanied by increased bone mass. Lipopolysaccharide-induced osteoclast formation and osteolysis were significantly inhibited in Traf6 conditional knockout mice. Our results suggest that Traf6 plays a crucial role in regulating M1 osteoclast and M2 FBGC polarization and is a potential therapeutic target in blocking FBGC inhibition, antagonizing osteolysis in inflammatory conditions, and increasing bone mass without adverse effects in adults.

Up-regulation of TNF Receptor-associated Factor 7 after spinal cord injury in rats may have implication for neuronal apoptosis. Neuropeptides 2018; 71:81-89.

Abstract
TNF receptor-associated factor 7 (TRAF7), is an E3 ubiquitin ligase for several proteins involved in the activation of TLR-dependent NF-kappaB signaling. TRAF7 links TNF receptor family proteins to signaling pathways, thus participates in regulating cell death and survival mediated by TNF family ligands. To date, the biological function of TRAF7 after spinal cord injury (SCI) is still with limited acquaintance. In this study, we have performed an acute SCI model in adult rats and investigated the dynamic changes of TRAF7 expression in the spinal cord. Our results showed that TRAF7 was up-regulated significantly after SCI, which was paralleled with the levels of the apoptotic protein active caspase-3. Immunofluorescent labeling showed that TRAF7 was co-localizated with active caspase-3 in neurons. To further investigate the function of TRAF7, an apoptosis model was established in primary neuronal cells. When TRAF7 was knocked down by specific short interfering RNA (siRNA), the protein levels of active caspase-3 and the number of apoptotic primary neurons were significantly decreased in our study. Taken together, our findings suggest that the change of TRAF7 protein expression plays a key role in neuronal apoptosis after SCI.

Abstract
The tumor necrosis factor receptor (TNF-R)-associated factor (TRAF) family of cytoplasmic adaptor proteins regulate the signal transduction pathways of a variety of receptors, including the TNF-R superfamily, Toll-like receptors (TLRs), NOD-like receptors (NLRs), RIG-I-like receptors (RLRs), and cytokine receptors. TRAF-dependent signaling pathways participate in a diverse array of important cellular processes, including the survival, proliferation, differentiation, and activation of different cell types. Many of these TRAF-dependent signaling pathways have been implicated in cancer pathogenesis. Here we analyze the current evidence of genetic alterations of TRAF molecules available from The Cancer Genome Atlas (TCGA) and the Catalog of Somatic Mutations in Cancer (COSMIC) as well as the published literature, including copy number variations and mutation landscape of TRAFs in various human cancers. Such analyses reveal that both gain- and loss-of-function genetic alterations of different TRAF proteins are commonly present in a number of human cancers. These include pancreatic cancer, meningioma, breast cancer, prostate cancer, lung cancer, liver cancer, head and neck cancer, stomach cancer, colon cancer, bladder cancer, uterine cancer, melanoma, sarcoma, and B cell malignancies, among others. Furthermore, we summarize the key in vivo and in vitro evidence that demonstrates the causal roles of genetic alterations of TRAF proteins in tumorigenesis within different cell types and organs. Taken together, the information presented in this review provides a rationale for the development of therapeutic strategies to manipulate TRAF proteins or TRAF-dependent signaling pathways in different human cancers by precision medicine.

De Novo Missense Variants in TRAF7 Cause Developmental Delay, Congenital Anomalies, and Dysmorphic Features. Am J Hum Genet 2018; 103:154-162.

Abstract
TRAF7 is a multi-functional protein involved in diverse signaling pathways and cellular processes. The phenotypic consequence of germline TRAF7 variants remains unclear. Here we report missense variants in TRAF7 in seven unrelated individuals referred for clinical exome sequencing. The seven individuals share substantial phenotypic overlap, with developmental delay, congenital heart defects, limb and digital anomalies, and dysmorphic features emerging as key unifying features. The identified variants are de novo in six individuals and comprise four distinct missense changes, including a c.1964G>A (p.Arg655Gln) variant that is recurrent in four individuals. These variants affect evolutionarily conserved amino acids and are located in key functional domains. Gene-specific mutation rate analysis showed that the occurrence of the de novo variants in TRAF7 (p = 2.6 × 10-3) and the recurrent de novo c.1964G>A (p.Arg655Gln) variant (p = 1.9 × 10-8) in our exome cohort was unlikely to have occurred by chance. In vitro analyses of the observed TRAF7 mutations showed reduced ERK1/2 phosphorylation. Our findings suggest that missense mutations in TRAF7 are associated with a multisystem disorder and provide evidence of a role for TRAF7 in human development.

Abstract
Constitutive NF-κB signaling represents a hallmark of chronic inflammation and autoimmune diseases. The E3 ligase TNF receptor-associated factor 6 (TRAF6) acts as a key regulator bridging innate immunity, pro-inflammatory cytokines, and antigen receptors to the canonical NF-κB pathway. Structural analysis and point mutations have unraveled the essential role of TRAF6 binding to the E2-conjugating enzyme ubiquitin-conjugating enzyme E2 N (Ubc13 or UBE2N) to generate Lys63-linked ubiquitin chains for inflammatory and immune signal propagation. Genetic mutations disrupting TRAF6-Ubc13 binding have been shown to reduce TRAF6 activity and, consequently, NF-κB activation. However, to date, no small-molecule modulator is available to inhibit the TRAF6-Ubc13 interaction and thereby counteract NF-κB signaling and associated diseases. Here, using a high-throughput small-molecule screening approach, we discovered an inhibitor of the TRAF6-Ubc13 interaction that reduces TRAF6-Ubc13 activity both in vitro and in cells. We found that this compound, C25-140, impedes NF-κB activation in various immune and inflammatory signaling pathways also in primary human and murine cells. Importantly, C25-140 ameliorated inflammation and improved disease outcomes of autoimmune psoriasis and rheumatoid arthritis in preclinical in vivo mouse models. Hence, the first-in-class TRAF6-Ubc13 inhibitor C25-140 expands the toolbox for studying the impact of the ubiquitin system on immune signaling and underscores the importance of TRAF6 E3 ligase activity in psoriasis and rheumatoid arthritis. We propose that inhibition of TRAF6 activity by small molecules represents a promising novel strategy for targeting autoimmune and chronic inflammatory diseases.

Abstract
MicroRNA (miR) is reported to be involved in vascular inflammation and may represent a novel class of diagnostic biomarkers in cardiovascular disease. We aimed to identify the miR expression profile in human advanced coronary atherosclerotic plaques (CAP) and to connect this expression to the processes in atherosclerosis. Microarray techniques and TaqMan polymerase chain reaction were used to analyse the global expression of 352 miRs in CAP obtained during ACS MULTI-LINK study. 11 miRs were selected on the basis of their implication in atherosclerosis, endothelial activation, and inflammation. 6 miRs were found to be differently expressed in CAP when compared to non-atherosclerotic internal mammary arteries (IMA, p < 0.05). The expression of miR-21, -92a, and -99a was verified and found to be significantly up-regulated in CAP versus IMA (p < 0.001). We also performed bioinformatic analysis and found several potential target genes of miR-92a and -99a as well as several pathways with impact on atherosclerosis which could be differently expressed due to this miRNA profile. The most up-regulated miRs are involved in processes known to be connected to atherosclerosis. Interfering with the miR expression in the artery wall is a potential way to affect atherosclerotic plaque and cardiovascular disease development.

Abstract
BACKGROUND AND AIM Non-small cell lung cancer (NSCLC), which comprises 80%-85% of all lung cancer cases, is one of the most common human malignancies. Despite great improvements in diagnostic technology and the introduction of new therapeutic agents in recent years, the 5-year survival rate of NSCLC is still low. Tumor necrosis factor (TNF) receptor-associated factor 1 (TRAF1) plays an important role in the TNF-related apoptosis-inducing ligand (TRAIL) associated signal pathway. METHODS In this study, we aim to illuminate the function of TRAF1 in NSCLC. Toward that end, TRAF1 expression was detected using immunohistochemistry (IHC) in specimens from 200 NSCLC patients. The function of TRAF1 in the A549 and H1299 cell lines was evaluated by colony formation and MTT assays. RESULTS Our data showed that TRAF1 was significantly upregulated in NSCLC tissues. TRAF1 expression was positively associated with NSCLC lymphatic metastasis and clinical stage and was negatively associated with overall patient survival. TRAF1 promoted NSCLC cell proliferation CONCLUSION: TRAF1 expression was positively associated with NSCLC lymphatic metastasis and histological grade and was negatively associated with overall patient survival. TRAF1 may be an important therapeutic target for NSCLC.

Abstract
The ability of a C-terminal truncated form of TRAF2 to bind synthetic vesicles has been quantitatively studied by steady-state fluorescence energy transfer from the protein to large unilamellar vesicles (LUVs) prepared with different lipid mixtures. The dissociation constants, the free energy of binding, and the average number of phospholipids interacting with truncated TRAF2 have been evaluated from the corresponding binding curves. The results indicate that the protein strongly interacts with the lipid bilayer, preferentially in the monomeric state. These findings have been discussed in terms of their possible role in the activity of TRAF2 in vivo.

Abstract
B cell activating factor (BAFF) is an important cytokine for the maintenance of B cell development, survival and homeostasis. BAFF/BAFF-R could directly activate nuclear factor kappa B (NF-κB) pathway. Tumour necrosis factor receptor-associated factors (TRAFs) are key regulatory proteins in NF-κB signaling pathways. TRAF1 enhances the activation of tumor necrosis factor receptor 2 (TNF-R2) induced by NF-κB. TRAF2 and TRAF3 signal adapters act cooperatively to control the maturation and survival signals mediated by BAFF receptor. TRAF5 is most homologous to TRAF3, as well as most functionally similar to TRAF2. TRAF6 is also required for the BAFF-mediated activation of NF-κB signal pathway. TRAF7 is involved in signal transduction pathways that lead either to activation or repression of NF-κB transcription factor. In this article, we reviewed the roles of TRAFs in NF-κB signaling pathway mediated by BAFF.
