Wu XY, Zhang ZW, Chen SN, Pang AN, Peng XY, Li N, Liu LH, Nie P. SIRT6 positively regulates antiviral response in a bony fish, the Chinese perch Siniperca chuatsi. FISH & SHELLFISH IMMUNOLOGY 2024; 150:109662. [PMID: 38821229 DOI: 10.1016/j.fsi.2024.109662] [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: 05/07/2024] [Revised: 05/24/2024] [Accepted: 05/27/2024] [Indexed: 06/02/2024]
Abstract
SIRT6, a key member of the sirtuin family, plays a pivotal role in regulating a number of vital biological processes, including energy metabolism, oxidative stress, and immune system modulation. Nevertheless, the function of SIRT6 in bony fish, particularly in the context of antiviral immune response, remains largely unexplored. In this study, a sirt6 was cloned and characterized in a commercial fish, the Chinese perch (Siniperca chuatsi). The SIRT6 possesses conserved SIR2 domain with catalytic core region when compared with other vertebrates. Tissue distribution analysis indicated that sirt6 was expressed in all detected tissues, and the sirt6 was significantly induced following infection of infectious haemorrhagic syndrome virus (IHSV). The overexpression of SIRT6 resulted in significant upregulation of interferon-stimulated genes (ISGs), such as viperin, mx, isg15, irf3 and ifp35, and inhibited viral replication. It was further found that SIRT6 was located in nucleus and could enhance the expression of ISGs induced by type I and II IFNs. These findings may provide new information in relation with the function of SIRT6 in vertebrates, and with viral prevention strategy development in aquaculture.

Abstract
Sirtuins are Nicotinamide Adenine Dinucleotide (NAD+) dependent class ІΙΙ histone deacetylases enzymes (HDACs) present from lower to higher organisms such as bacteria (Sulfolobus solfataricus L. major), yeasts (Saccharomyces cerevisiae), nematodes (Caenorhabditis elegans), fruit flies (Drosophila melanogaster), humans (Homo sapiens sapiens), even in plants such as rice (Oryza sativa), thale cress (Arabidopsis thaliana), vine (Vitis vinifera L.) tomato (Solanum lycopersicum). Sirtuins play an important role in the regulation of various vital cellular functions during metabolism and ageing. It also plays a neuroprotective role by modulating several biological pathways such as apoptosis, DNA repair, protein aggregation, and inflammatory processes associated with ageing and neurodegenerative diseases. In this review, we have presented an updated Sirtuins and its role in ageing and age-related neurodegenerative diseases (NDDs). Further, this review also describes the therapeutic potential of Sirtuins and the use of Sirtuins inhibitor/activator for altering the NDDs disease pathology.

Abstract
Studying the evolutionary history of gene families is a challenging and exciting task with a wide range of implications. In addition to exploring fundamental questions about the origin and evolution of genes, disentangling their evolution is also critical to those who do functional/structural studies to allow a deeper and more precise interpretation of their results in an evolutionary context. The sirtuin gene family is a group of genes that are involved in a variety of biological functions mostly related to aging. Their duplicative history is an open question, as well as the definition of the repertoire of sirtuin genes among vertebrates. Our results show a well-resolved phylogeny that represents an improvement in our understanding of the duplicative history of the sirtuin gene family. We identified a new sirtuin gene family member (SIRT3.2) that was apparently lost in the last common ancestor of amniotes but retained in all other groups of jawed vertebrates. According to our experimental analyses, elephant shark SIRT3.2 protein is located in mitochondria, the overexpression of which leads to an increase in cellular levels of ATP. Moreover, in vitro analysis demonstrated that it has deacetylase activity being modulated in a similar way to mammalian SIRT3. Our results indicate that there are at least eight sirtuin paralogs among vertebrates and that all of them can be traced back to the last common ancestor of the group that existed between 676 and 615 millions of years ago.

Abstract
The homeobox genes play important roles in the embryonic development of animals. Recent evidence suggests they might also regulate feeding and act as transcription factors of appetite regulators. Examples of these genes are a brain-specific homeobox transcription factor (BSX), NK2 homeobox 1 (NKX2.1) and the Iroquois homeobox 3 (IRX3). Sirtuin1 (SIRT1) acts as a transcription factor for nutrient (e.g. lipid, glucose) homeostasis and responds to stress and nutrient availability, and has been shown to interact with appetite regulators. Very little is known about the role of these genes in the regulation of feeding and nutrient homeostasis in fish. In this study, we assessed the roles of BSX, NKX2.1, IRX3 and SIRT1 in the central regulation of feeding in goldfish by examining their mRNA brain distribution, assessing the effects of fasting on their brain expression and assessing the effects of peripheral injections of cholecystokinin (CCK, a brain-gut peptide), on their brain expression. All genes showed a widespread distribution in the brain, with high levels in the hypothalamus. In both hypothalamus and telencephalon, fasting induced increases in BSX, IRX3 and NKX2.1 expressions but had no effect on SIRT1 expression levels. CCK injections increased hypothalamic expression levels of IRX3 and SIRT1, and telencephalic expression levels of NKX2.1 and SIRT1, with no effect on either hypothalamic BSX or NKX2.1 expression levels or telencephalon BSX or IRX3 expression levels. Our results suggest that, in goldfish as in mammals, central BSX, NKX2.1, IRX3 and SIRT1 are present in regions of the brain regulating feeding, are sensitive to nutrient status and interact with appetite-regulating peptides.

SUCLA2 mutations cause global protein succinylation contributing to the pathomechanism of a hereditary mitochondrial disease. Nat Commun 2020; 11:5927.

Abstract
Mitochondrial acyl-coenzyme A species are emerging as important sources of protein modification and damage. Succinyl-CoA ligase (SCL) deficiency causes a mitochondrial encephalomyopathy of unknown pathomechanism. Here, we show that succinyl-CoA accumulates in cells derived from patients with recessive mutations in the tricarboxylic acid cycle (TCA) gene succinyl-CoA ligase subunit-β (SUCLA2), causing global protein hyper-succinylation. Using mass spectrometry, we quantify nearly 1,000 protein succinylation sites on 366 proteins from patient-derived fibroblasts and myotubes. Interestingly, hyper-succinylated proteins are distributed across cellular compartments, and many are known targets of the (NAD+)-dependent desuccinylase SIRT5. To test the contribution of hyper-succinylation to disease progression, we develop a zebrafish model of the SCL deficiency and find that SIRT5 gain-of-function reduces global protein succinylation and improves survival. Thus, increased succinyl-CoA levels contribute to the pathology of SCL deficiency through post-translational modifications. The pathomechanism of succinyl-CoA ligase (SCL) deficiency, a hereditary mitochondrial disease, is not fully understood. Here, the authors show that increased succinyl-CoA levels contribute to SCL pathology by causing global protein hyper-succinylation.

Abstract
This study sought to characterize sirtuin 2 (sirt2), sirtuin 3 (sirt3), and sirtuin 5 (sirt5) in Megalobrama amblycephala (M. amblycephala) by cloning the open reading frame (ORF) of sirt2, sirt3, and sirt5. The full-lengths of the resulting M. amblycephala sirt2, sirt3, and sirt5 cDNA sequences were 1845, 1534, and 1920 bp, respectively, with 92%, 98%, and 91% similarities to Danio rerio sequences. Based on our bioinformatic analyses and predictions, the sirt2 and sirt3 genes of M. amblycephala were classified within the Sir2 I family, whereas sirt5 belonged to the Sir2 III family. Furthermore, sirt2, sirt3, and sirt5 were widely distributed in different M. amblycephala tissues. Particularly, sirt2 and sirt5 were highly expressed in gills, intestines, and liver (P < 0.05), whereas sirt3 was highly expressed in gills, kidney, liver, and spleen (P < 0.05). A 2 × 2 factorial experiment was also conducted to analyze sirt2, sirt3, and sirt5 expression patterns in response to acute temperature (25 and 32 °C) and ammonia nitrogen (0 and 20 mg/L) stress. Notably, these two stressors were found to interactively affect sirt2, sirt3, and sirt5 expression patterns in M. amblycephala liver. At the higher water temperature (32 °C) and ammonia nitrogen concentration (20 mg/L) tested herein, sirt2, sirt3, and sirt5 had similar expression levels and exhibited a down-regulation trend at 6 and 48 h post-stress but became up-regulated thereafter to counteract the stressors at 96 h post-stress.

Abstract
Exposures to low ambient temperature require ectothermic fish to not only adjust their metabolic machinery but also to mount protective responses against oxidative stress. In this study, we tested whether diets supplemented with resveratrol (RSV), a naturally occurring polyphenol known to stimulate metabolic and protective responses in various animals, would be beneficial to tilapia (Oreochromis mossambicus) under hypothermic challenge. Feeding tilapia with RSV-supplemented diet promoted liver expression of sirtuins and their known targets, including metabolic/antioxidative enzymes. After exposure to 15 °C cold conditions for three days, the oxygen–nitrogen (O:N) ratio was decreased in the control-diet-fed tilapia but not in their RSV-fed counterparts. Moreover, at 27 °C, RSV-fed tilapia showed significantly higher prolonged swim speed compared with controls. RSV feeding produced no significant effect on upper and bottom layer preference between the control- and RSV-treated tilapia at either 27 °C or 15 °C. Together, these findings suggest that RSV stimulates beneficial metabolic/antioxidative adjustments in teleosts and may serve as a valuable feed supplement for tropical fish exposed to cold stress during winter.

Abstract
The founding member of the sirtuin family, yeast Sir2, was the first evolutionarily conserved gene to be identified as a regulator of longevity. Sirtuins constitute a protein family of metabolic sensors, translating changes in NAD + levels into adaptive responses, thereby acting as crucial regulators of the network that controls energy homeostasis and as such determines healthspan. In mammals the sirtuin family comprises seven proteins, SIRT1-SIRT7, which vary in tissue specificity, subcellular localization, enzymatic activity and targets. Here, we report the identification and a detailed spatio-temporal expression profile of sirtuin genes in the short-lived fish Nothobranchius furzeri, from embryogenesis to late adulthood, mapping its entire life cycle. Database exploration of the recently published N. furzeri genome revealed eight orthologues corresponding to the seven known mammalian sirtuins, including two copies of the sirt5 gene. Phylogenetic analysis showed high cross species similarity of individual sirtuins in both their overall amino acid sequence and catalytic domain, suggesting a high degree of functional conservation. Moreover, we show that N. furzeri sirtuins exhibit ubiquitous and wide tissue distribution with a unique spatial expression pattern for each individual member of this enzyme family. Specifically, we observed a transcriptional down-regulation of several sirtuin genes with age, most significantly sirt1, sirt5a, sirt6 and sirt7 in a wide range of functionally distinct tissues. Overall, this spatio-temporal expression analysis provides the foundation for future research, both into genetic and pharmacological manipulation of this important group of enzymes in Nothobranchius furzeri, an emerging model organism for aging research.

Abstract
Studies have demonstrated that zebrafish are powerful tools for monitoring environmental toxicity, including radiation hazard. Here we investigated the developmental toxicity of ionizing radiation (IR) in an in vivo embryonic zebrafish model. The effects of heavy ion (12 C6+ ), proton, and X-ray radiation on early zebrafish embryos were determined. A similar dose-dependent decrease in the hatch and survival rate of zebrafish embryos was observed after exposure to these irradiations. Exposure of zebrafish embryos to 1-4 Gy IR caused significant loss of pigmentation. Quantitative real-time reverse transcription polymerase chain reaction, western blot analysis, and in situ hybridization (ISH) experiment revealed that atp5α1 was markedly upregulated in irradiated zebrafish embryos. In addition, IR resulted in a rapid decrease in total adenosine triphosphate (ATP) generation. With dual functions of synthesizing or hydrolyzing ATP, ATP synthase regulated H+ transport crossing the mitochondrial inner. Administration of the mitochondrial ATP synthase inhibitor, oligomycin, partially restored pigmentation in irradiated zebrafish embryos, but the ATPase inhibitor, BTB06584, had no effect. Taken together, these results showed that IR exposure downregulated zebrafish pigmentation through regulation of H+ ion transport in mitochondria.

Comp Biochem Physiol C Toxicol Pharmacol 2018; 208:71-76. [PMID: 29054583 PMCID: PMC5906208 DOI: 10.1016/j.cbpc.2017.10.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2017] [Revised: 10/13/2017] [Accepted: 10/15/2017] [Indexed: 12/27/2022]
Abstract
The decline of female reproductive function is an early phenotype of aging in humans, occurring only midway through the lifespan. Yet the number of women delaying pregnancy continues to rise in industrialized societies due to personal or socioeconomic circumstances, often resulting in subfertility or difficulty conceiving. There are few defined mechanisms associated with this etiology, and equally few effective therapies. To combat this problem, we used a novel emerging model, Nothobranchius guentheri, that recapitulates the age-associated spectrum of changes that adversely affect human fertility. We hypothesized that resveratrol (RSV), which activates SirT1 as an oxidative stress sensor and longevity assurance enzyme, would improve female fecundity in mid-life. RSV, a polyphenol found in grapes and red wine, has been touted as an anti-aging dietary supplement due to its ability to prolong both lifespan and health span. SirT1 is an NAD+ dependent histone deacetylase, whose activity is regulated by the nicotinamide to NAD+ salvage pathway, especially the rate-limiting enzyme NAMPT. We found that female N. guentheri fed 600μgRSV/g food into mid-life (~20weeks), beginning at sexual maturity, showed increased embryo production compared to those on Control diet. Furthermore, the RSV-fed fish had significantly increased NAMPT. This suggests that dietary RSV has a positive effect on female fertility, and that it may become an effective therapy to regulate sirtuin activity and combat reproductive senescence.

World J Hepatol 2017; 9:418-426. [PMID: 28357029 PMCID: PMC5355764 DOI: 10.4254/wjh.v9.i8.418] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2016] [Revised: 10/28/2016] [Accepted: 01/14/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To evaluate the effects of chronic exposure to ethanol in the liver and the expression of inflammatory genes in zebrafish.
METHODS Zebrafish (n = 104), wild type, adult, male and female, were divided into two groups: Control and ethanol (0.05 v/v). The ethanol was directly added into water; tanks water were changed every two days and the ethanol replaced. The animals were fed twice a day with fish food until satiety. After two and four weeks of trial, livers were dissected, histological analysis (hematoxilin-eosin and Oil Red staining) and gene expression assessment of adiponectin, adiponectin receptor 2 (adipor2), sirtuin-1 (sirt-1), tumor necrosis factor-alpha (tnf-a), interleukin-1b (il-1b) and interleukin-10 (il-10) were performed. Ultrastructural evaluations were conducted at fourth week.
RESULTS Exposing zebrafish to 0.5% ethanol developed intense liver steatosis after four weeks, as demonstrated by oil red staining. In ethanol-treated animals, the main ultrastructural changes were related to cytoplasmic lipid particles and droplets, increased number of rough endoplasmic reticulum cisterns and glycogen particles. Between two and four weeks, hepatic mRNA expression of il-1b, sirt-1 and adipor2 were upregulated, indicating that ethanol triggered signaling molecules which are key elements in both hepatic inflammatory and protective responses. Adiponectin was not detected in the liver of animals exposed and not exposed to ethanol, and il-10 did not show significant difference.
CONCLUSION Data suggest that inflammatory signaling and ultrastructural alterations play a significant role during hepatic steatosis in zebrafish chronically exposed to ethanol.

Abstract
Resveratrol has been reported to ameliorate Cd-induced nephrotoxicity. However, the beneficial effects of resveratrol on Cd-induced nephrotoxicity and the underlying mechanisms of this protection remain unclear. Here, we showed that mouse renal tubular epithelial (TCMK-1) cells exposed to Cd experienced significantly increased mitochondrial reactive oxygen species (mROS) production, as well as decreased mitochondrial biogenesis and function. Cd exposure dramatically decreased Sirt3 protein expression and activity and promoted the acetylation of forkhead box O3 (FoxO3a). Moreover, Cd exposure led to a decreased binding affinity of FoxO3a to the promoters of both peroxisome proliferator-activated receptor-gamma coactivator (PGC)-1α and superoxide dismutase 2 (SOD2), powerful and broad regulators of mitochondrial biogenesis and mROS metabolism. Meanwhile, resveratrol remarkably reduced mROS generation by promoting Sirt3 enrichment within the mitochondria and subsequent upregulation of FoxO3a-mediated mitochondria gene expression of PGC-1α and SOD2. Importantly, mechanistic study revealed that ERK1/2 activation was associated with increased apoptosis induced by Cd, resveratrol suppressed Cd-induced apoptosis in mice kidney. Taken together, our data suggest a novel mechanism of action for resveratrol-attenuated Cd-induced cellular damage, which, in part, was mediated through the activation of the Sirt3/FoxO3a signaling pathway.

Abstract
Age is the most important risk factor for metabolic alterations and cardiovascular accidents. Although class III histone deacetylases, alias Sirtuins, have been appealed as "the fountain of youth" their role in longevity control and prevention of aging-associated disease is still under debate. Indeed, several lines of evidence indicate that sirtuin activity is strictly linked to metabolism and dependent on NAD(+) synthesis both often altered as aging progresses. During aging the cardiovascular system is attacked by a variety of environmental stresses, including those determined by high blood glucose and lipid levels, or by the presence of oxidized lipoproteins which, among others, determine important oxidative stress signals. In such a milieu, heart and vessels develop a functional impairment leading to atherosclerosis, ischemia, heart insufficiency and failure. Sirtuins, which are believed to have a positive impact on cardiovascular physiology and physiopathology, are distributed in different subcellular compartments including the nucleus, the cytoplasm and the mitochondria, where they regulate expression and function of a large variety of target genes and proteins. Remarkably, experimental animal models indicate resveratrol, the first natural compound described to positively regulate the activity of sirtuins, as able to protect the endothelium and the heart exposed to a variety of stress agents. This review will focus on the regulation and function of mammalian sirtuins with special attention paid to their role as cardiovascular "defenders" giving indication of their targets of potential relevance for the development of future therapeutics. This article is part of a Special Issue entitled CV Aging.

Abstract
A 5-week study was conducted to evaluate commercially available Artemia, Ziegler zebrafish diet, and Calamac diet fed in five different feeding regimes on the growth and reproductive development of 7-month-old zebrafish. Zebrafish were fed to satiation three times daily during the normal work week and twice daily during the weekend and holidays. Zebrafish in dietary groups CCC (Calamac three times daily) and CCA (Calamac twice daily, Artemia once daily) had a significantly (p<0.05) greater weight gain and specific growth rate as compared to all other dietary groups. Male zebrafish in dietary group 5 had significantly larger gonadosomatic index (GSI) values than all other groups, while female zebrafish in dietary group CCC had significantly larger GSI values than all other groups. No differences in the fatty acid content of female gonads were detected. Zebrafish fed solely Artemia had the greatest weight loss and lowest GSI values. Preliminary evidence of protein sparing in zebrafish is reported. Collectively, this study sheds more light into the effects of the use of commercially available feeds and feeding regime on the rearing of zebrafish.

Abstract
BACKGROUND Nonalcoholic fatty liver disease is one of the most prevalent forms of chronic liver disease in the Western world. Taurine is a conditionally essential amino acid in humans that may be a promising therapy for treating this disease. AIM To evaluate the effect of taurine on hepatic steatosis induced by thioacetamide in Danio rerio. METHODS Animals were divided into four groups: control (20 μl of saline solution), taurine (1,000 mg/kg), thioacetamide (300 mg/kg), and the taurine-thioacetamide group (1,000 + 300 mg/kg). Thioacetamide was injected intraperitoneally three times a week for 2 weeks. The mRNA expression, lipoperoxidation, antioxidant enzymatic activity, and histological analyses were evaluated in the liver and the triglyceride content was assessed in the serum. RESULTS Thioacetamide injection induced steatosis, as indicated by histological analyses. The lipoperoxidation showed significant lipid damage in the thioacetamide group compared to the taurine-thioacetamide group (p < 0.001). Superoxide dismutase (SOD) activity in the taurine-thioacetamide group (5.95 ± 0.40) was significantly increased compared to the thioacetamide group (4.14 ± 0.18 U SOD/mg of protein) (p < 0.001). The mRNA expression of SIRT1 (0.5-fold) and Adiponectin receptor 2 (0.39-fold) were lower in the thioacetamide group than the control (p < 0.05). TNF-α mRNA expression was 6.4-fold higher in the thioacetamide group than the control (p < 0.05). SIRT1 mRNA expression was 2.6-fold higher in the taurine-thioacetamide group than in the thioacetamide group. CONCLUSIONS Taurine seems to improve hepatic steatosis by reducing oxidative stress and increasing SIRT1 expression.

Abstract
The zebrafish, Danio rerio, a small, tropical freshwater species native to Pakistan and India, has become a National Institutes of Health-sanctioned model organism and, due to its many advantages as an experimental vertebrate, it has garnered intense interest from the world's scientific community. Some have labeled the zebrafish, the "vertebrate Drosophila," due to its genetic tractability, small size, low cost, and rapid development. The transparency of the embryo, external development, and the many hundreds of mutant and transgenic lines available add to the allure. Now it appears, the zebrafish can be used for high-throughput screening (HTS) of drug libraries in the discovery process of promising new therapeutics. In this review, various types of screening methods are briefly outlined, as are a variety of screens for different disease models, to highlight the range of zebrafish HTS possibilities. High-content screening (HCS) has been available for cell-based screens for some time and, very recently, HCS is being adapted for the zebrafish. This will allow analysis, at high resolution, of drug effects on whole vertebrates; thus, whole body effects as well as those on specific organs and tissues may be determined.
