Genes (Basel) 2023; 14:1388. [PMID: 37510293 PMCID: PMC10379648 DOI: 10.3390/genes14071388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 06/25/2023] [Accepted: 06/29/2023] [Indexed: 07/30/2023] Open
Abstract
Toll-like receptor (TLR) signaling is conserved between fish and mammals, except for TLR4, which is absent in most fish. In the present study, we aimed to evaluate whether TLR4 is expressed in Schizothorax prenanti (SpTLR4). The SpTLR2 and SpTLR4 were cloned and identified, and their tissue distribution was examined. The cDNA encoding SpTLR4 and SpTLR2 complete coding sequences (CDS) were identified and cloned. Additionally, we examined the expression levels of seven SpTLRs (SpTLR2, 3, 4, 18, 22-1, 22-2, and 22-3), as well as SpMyD88 and SpIRF3 in the liver, head kidney, hindgut, and spleen of S. prenanti, after intraperitoneal injection of polyinosinic-polycytidylic acid (poly (I:C)). The SpTLR2 and SpTLR4 shared amino acid sequence identity of 42.15-96.21% and 36.21-93.58%, respectively, with sequences from other vertebrates. SpTLR2 and SpTLR4 were expressed in all S. prenanti tissues examined, particularly in immune-related tissues. Poly (I:C) significantly upregulated most of the genes evaluated in the four immune organs compared with the PBS-control (p < 0.05); expression of these different genes was tissue-specific. Our findings demonstrate that TLR2 and TLR4 are expressed in S. prenanti and that poly (I:C) affects the expression of nine TLR-related genes, which are potentially involved in S. prenanti antiviral immunity or mediating pathological processes with differential kinetics. This will contribute to a better understanding of the roles of these TLR-related genes in antiviral immunity.

Comprehensive transcriptomics and proteomics analysis of Carassius auratus gills in response to Aeromonas hydrophila. FISH AND SHELLFISH IMMUNOLOGY REPORTS 2022; 4:100077. [PMID: 36589261 PMCID: PMC9798182 DOI: 10.1016/j.fsirep.2022.100077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 12/11/2022] [Accepted: 12/13/2022] [Indexed: 12/15/2022] Open
Abstract
As one of the mucosal barriers, fish gills represent the first line of defense against pathogen infection. However, the exact mechanism of gill mucosal immune response to bacterial infection still needs further investigation in fish. Here, to investigate pathological changes and molecular mechanisms of the mucosal immune response in the gills of crucian carp (Carassius auratus) challenged by Aeromonas hydrophila, the transcriptomics and proteomics were performed by using multi-omics analyses of RNA-seq coupled with iTRAQ techniques. The results demonstrated gill immune response were mostly related to the activation of complement and coagulation cascades, antigen processing and presentation, phagosome, NOD-like receptor (NLR) and nuclear factor κB (NFκB) signaling pathway. Selected 21 immune-related DEGs (ie., Clam, nfyal, snrpf, acin1b, psme, sf3b5, rbm8a, rbm25, prpf18, g3bp2, snrpd3l, tecrem-2, cfl-A, C7, lysC, ddx5, hsp90, α-2M, C9, C3 and slc4a1a) were verified for their immune roles in the A. hydrophila infection via using qRT-PCR assay. Meanwhile, some complement (C3, C7, C9, CFD, DF and FH) and antigen presenting (HSP90, MHC Ⅱ, CALR, CANX and PSME) proteins were significantly participated in the process of defense against infections in gill tissues, and protein-protein interaction (PPI) network displayed the immune signaling pathways and interactions among these DEPs. The correlation analysis indicated that the iTRAQ and qRT-PCR results was significantly correlated (Pearson's correlation coefficient = 0.70, p < 0.01). To our knowledge, the transcriptomics and proteomics of gills firstly identified by multi-omics analyses contribute to understanding on the molecular mechanisms of local mucosal immunity in cyprinid species.

Heat shock protein 90 of Pacific white shrimp (Litopenaeus vannamei) is possibly involved in promoting white spot syndrome virus infection. FISH & SHELLFISH IMMUNOLOGY 2022; 128:405-418. [PMID: 35964878 DOI: 10.1016/j.fsi.2022.08.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Revised: 08/01/2022] [Accepted: 08/05/2022] [Indexed: 06/15/2023]
Abstract
Viruses cause up to 60% of disease-associated losses in shrimp aquaculture, and the white spot syndrome virus (WSSV) is a major viral pathogen in shrimp. Heat shock proteins (HSPs) are host chaperones that help promote many viral infections. We investigated the involvement of Litopenaeus vannamei (Lv) HSP90 in WSSV infections. Expression of LvHSP90 at the transcript and protein levels were upregulated after WSSV infection. Silencing LvHSP90 resulted in the increased cumulative mortality rate and the reduction of circulating hemocytes. The inhibition of LvHSP90 also induced the expression of apoptosis-related genes which indicated the induction of apoptotic pathway and might lead to shrimp death. However, lower the number of WSSV-infected cells and viral copy numbers were detected in the LvHSP90-silenced shrimp compared with those of the controls, corresponding with significantly decreased expressions of viral genes, including the immediate-early genes WSV083 and WSV249 and viral DNA polymerase. Conversely, injecting shrimp with WSSV that had been co-incubated with a recombinant LvHSP90 (rLvHSP90) promoted WSSV infection as evidenced by an increased cumulative mortality rate and viral copy numbers at 40-48 h post infection (hpi). Subcellular localization of LvHSP90 in WSSV-infected hemocytes at 3, 6 and 12 hpi demonstrated increased expression and translocation of LvHSP90 into the nucleus where WSSV DNA can replicate. Thus, LvHSP90 might be involved in the WSSV pathogenesis by promoting WSSV replication.

Schizothorax prenanti Heat Shock Protein 27 Gene: Cloning, Expression, and Comparison with Other Heat Shock Protein Genes after Poly (I:C) Induction. Animals (Basel) 2022; 12:ani12162034. [PMID: 36009624 PMCID: PMC9404436 DOI: 10.3390/ani12162034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 07/29/2022] [Accepted: 08/08/2022] [Indexed: 11/20/2022] Open
Abstract
We identified and cloned cDNA encoding the heat shock protein (Hsp) 27 gene from Schizothorax prenanti (SpHsp27), and compared its expression with that of SpHsp60, SpHsp70, and SpHsp90 in the liver, head kidney, hindgut, and spleen of S. prenanti that were injected with polyinosinic-polycytidylic acid [Poly (I:C)]. The SpHsp27 partial cDNA (sequence length, 653 bp; estimated molecular mass, 5.31 kDa; theoretical isoelectric point, 5.09) contained an open reading frame of 636 bp and a gene encoding 211 amino acids. The SpHsp27 amino acid sequence shared 61.0−92.89% identity with Hsp27 sequences from other vertebrates and SpHsp27 was expressed in seven S. prenanti tissues. Poly (I:C) significantly upregulated most SpHsps genes in the tissues at 12 or 24 h (p < 0.05) compared with control fish that were injected with phosphate-buffered saline. However, the intensity of responses of the four SpHsps was organ-specifically increased. The expression of SpHsp27 was increased 163-fold in the head kidney and 26.6-fold SpHsp27 in the liver at 24 h after Poly (I:C) injection. In contrast, SpHsp60 was increased 0.97−1.46-fold in four tissues and SpHsp90 was increased 1.21- and 1.16-fold in the liver and spleen at 12 h after Poly (I:C) injection. Our findings indicated that Poly (I:C) induced SpHsp27, SpHsp60, SpHsp70, and SpHsp90 expression and these organ-specific SpHsps are potentially involved in S. prenanti antiviral immunity or mediate pathological process.

Abstract
Heat shock proteins (HSPs) play a key role in anti-stress and immune processes and are associated with autoimmune diseases. In order to explore the immunological role of HSPs from Schizothorax prenanti (S. prenanti), SpHSP60 was cloned for the first time in this study, and the gene expressions of SpHSP27, SpHSP60, SpHSP70 and SpHSP90 in the hepatopancreas, head kidney, hindgut and spleen were analyzed by quantitative real-time PCR (qPCR) after treatment with lipopolysaccharide (LPS). The open reading frame of the SpHSP60 gene (GenBank accession number ON245159) is 1728 bp. It encodes a protein of 575 amino acids. Its C-terminus is a highly conserved and repeated glycine sequence, which is an important cofactor in ATP binding. Compared with the control group, most of the SpHSPs were significantly upregulated in the tissues examined at 12 or 24 h after LPS challenge. The most abundant expression of SpHSP70 was found in the head kidney at 24 h after LPS injection, followed by SpHSP27 in the spleen at 24 h; both of these SpHSPs displayed strong expression under the LPS stresses, about 20–70 fold more than that of SpHSP60 and SpHSP90. The temporal expression patterns of the four SpHSP genes were different in the four tissues examined. Taken together, the results suggest that SpHSP27, SpHSP60, SpHSP70 and SpHSP90 participate in innate immunity stimulated by LPS, and the response intensity of the SpHSPs was organ-specific, indicating they could provide early warning information against bacterial infection. The findings in our study will contribute to better understanding the biological processes and important roles of SpHSPs involved in defending against pathogenic bacterial challenge.

Abstract
Overwintering impacts common carp performance, yet the nature of changes is not known. The aim of the study was to compare the zootechnical and key performance indicators (KPI) of Cyprinus carpio wintering in a pond with no supplementary feeding (MCF), in a Recirculating Aquaculture System (RAS) fed typical (30% of protein and 8% of fat) carp diet (AFC), and in a RAS fed high protein (42%) and fat (12%) diet (ABF). The analysis showed that ABF fish had the highest final body weight and the Fulton’s condition factor, as well as the lowest food conversion rate compared with AFC and MCF fish. Histomorphological assessment revealed that MCF fish had thinner skin layers, a depleted population of mucous cells in skin, an excessive interlamellar mass in the gills, and no supranuclear vacuoles in the intestine compared to fish from RAS. At the molecular level, higher transcript levels of il-1β and il-6 transcripts were found in the gills of MCF than in fish from RAS. The transcript level of the intestinal muc5b was the highest in ABF fish. Relative expression of il-1β and il-6 in gills were presumably the highest due to lamellar fusions in MCF fish. Described KPIs may assist carp production to ensure sustainability and food security in the European Union.

Genomic organization and hypoxia inducible factor responsive regulation of teleost hsp90β gene during hypoxia stress. Mol Biol Rep 2021; 48:6491-6501.

Abstract
BACKGROUND The physiological significance of a large family of heat-shock proteins (HSPs), comprised of the cytosolic HSP90A and the endoplasmic reticulum component of HSPB, is evident in prokaryotes and eukaryotes. The HSP90A is believed to play critical roles in diverse physiological functions of cell viability and chromosomal stability including stress management. Heightened abundance of hsp90β transcript was documented in Channa striatus, a freshwater fish, which is capable of surviving within an extremely hypoxic environment. METHODS AND RESULTS To better understand the mechanism of hsp90β gene expression, we investigated its genomic organization. Eleven exons were identified, including a long upstream intron with a remarkable similarity with human, but not with chicken counterpart. Dual-luciferase assays identified promoter activity in a 1366 bp 5'-flanking segment beyond the transcription initiation site. Examination detected a minimal promoter of 754 bp containing a TATA-box, CAAT-enhancer in addition to providing clues regarding other enhancer and repressor elements. The driving capability of this minimal promoter was further validated by its binding ability with TATA-box binding protein and the generation of GFP expressing transgenic zebrafish (F2). Further, deletion of an inverted HIF (hypoxia inducible factor) motif RCGTG (upstream of the TATA-box) dramatically reduced luciferase expression in a hypoxic environment (CoCl2 treated cultivable cells) and was identified as a cis-acting HIF responsive element, necessary for the hypoxia-induced expression. CONCLUSIONS The results obtained herein provide an insight regarding how hsp90β gene expression is controlled by HIF responsive element in teleost both during hypoxia stress management and normal physiological functions, and suggested that the hsp90β gene promoter could be used as a potential candidate for generating ornamental and food-fish transgenics.

Abstract
In aquaculture, the incidence of enteritis due to Streptococcus iniae infection in Siberian sturgeon (Acipenser baerii) has increased in recent years. The pathogenesis of S. iniae is largely unknown due to the paucity of experimental studies on fish intestinal inflammation. In this study, S. iniae infection of A. baerii juveniles was induced by anal intubation of 0.15 mL at a low lethal dose (2 × 107 CFU/mL). Intestinal pathology and gene expression studies were conducted within 10 days of the experiment. Histopathological examination showed severe intestinal lesions, inflammatory cell infiltration, intestinal submucosa edema, epithelial cell shedding and necrosis. Predominant symptoms of exudative inflammation, metamorphic inflammation and proliferative inflammation on days 1-3, 4-6, and 7-10 post infection were shown, respectively. Ultrastructural observations also revealed fractured microvilli and shedding on days 4-6. Intestinal villi gradually repaired during the subsequent 7-10 days post infection. Expression of the pro-inflammatory cytokines, tumor necrosis factor and interleukin 1β were up-regulated on days 1-3 followed by a significant decrease on day 5, ultimately reaching control levels on day 10 post infection. A similar pattern was shown in mucus cells, involving mucin secretion and expression of the mucin encoding gene, Mucin-2. These results showed the cellular response to S. iniae infection associated with inflammatory genes expression in the Siberian sturgeon.

Abstract
Boran (n=15) and Nguni (n=15) cows were used in a study to determine the effect of breed, age and coat colour on the concentration of heat shock protein 90 (HSP90AB1), physiological rectal and skin temperature, and markers of health. The cows were exposed to summer heat stress and Boran cows had higher significant (P<0.05) skin temperature (35.1±0.42°C) as compared to the Nguni cows (36.0±0.38°C). Nguni cows had higher body thermal gradients than the Boran cows. Boran cows had thicker skin (P<0.05) and longer hairs (24.3±2.26mm) than their Nguni counterparts (20.2±2.00mm). The HSP90AB1 concentration was increased in Boran cows, although breed had no significant (P>0.05) influence. Significantly (P<0.05) high urea and total cholesterol was recorded in Boran cows. Coat colour had a significant (P<0.05) effect on the weight and rectal temperature of the study animals. Coat colour and age had no significant effect (P>0.05) on the concentration of HSP90AB1, although older cows (≥9 years) had higher concentrations (5.4±1.29ng/ml). Age had a significant (P<0.05) effect on packed cell volume, neutrophil/lymphocyte, urea, total protein and gamma-glutamyl transferase whereas cows with ≥9 years had more concentrations than young ones. Age significantly (P<0.05) influenced hair length, skin temperature and the thermal gradients. Breed was positively correlated (P<0.001) to coat colour, age, body condition score, weight and temperature humidity index while negatively correlated to urea and total cholesterol. It was concluded that Nguni cows were more adaptable to hot environments than the Boran cows as the latter were unable to balance thermal load between their bodies and the environment.
