Abstract
Warm temperature acclimation-related 65-kDa proteins (Wap65s) are fish plasma acute-phase glycoproteins homologous to hemopexin with high affinity and clearance for heme. The study characterized Mswap65-1 and Mswap65-2 genes in Micropterus salmoides. Structural analysis showed MsWap65s contained conserved heme-binding sites. MsWap65-1 had a chloride-binding site similar to hemopexin, while MsWap65-2 had an additional calcium-binding site. Phylogenetic and Ka/Ks analysis showed that fish Wap65s were evolutionarily conserved and underwent strong purifying selection. Functional divergence analysis indicated that fish Wap65-2 retained the putative function of ancestral Wap65, while Wap65-1 underwent neofunctional differentiation. QPCR showed Mswap65s were predominantly expressed in liver, but prolonged hyperthermy inhibited Mswap65-2 expression. Mswap65-2 expression was up-regulated in liver and spleen after Nocardia seriolae infection, while Mswap65-1 was down-regulated. MsWap65-2 may be associated with pathogenesis and play potential role in pathogen resistance. LMBV infection resulted in both significant downregulation of Mswap65s were both significantly down-regulated, with differences observed between sexes. We speculated the immune system might suppress expression after viral infection. Exogenous rMsWap65s were prepared, and injection of rMsWap65s alleviated phenylhydrazine-induced hemolysis and inhibited increases in heme, complement C3 and inflammatory symptoms. Our results contribute to an advanced understanding of the functions and mechanisms of MsWap65s in stress resistance.

DEVELOPMENTAL AND COMPARATIVE IMMUNOLOGY 2022; 135:104475. [PMID: 35732223 DOI: 10.1016/j.dci.2022.104475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 06/05/2022] [Accepted: 06/10/2022] [Indexed: 06/15/2023]
Abstract
Hemopexin is a vital glycoprotein for processing excessive iron in blood and functions as an iron scavenger in mammals. Teleosts however, unlike mammals, have two known hemopexin paralogs called warm temperature acclimation-related 65 kDa protein (Wap65-1 and Wap65-2, collectively termed Wap65s). Although Wap65s in rainbow trout have been considered notable biomarkers with significantly higher and/or lower expression under conditions of stress or disease, the individual roles, similarities and differences between the two paralogs are not well known. The aim of this study was to gain an understanding of the characteristics and functions of trout Wap65s from the perspective of iron-metabolism, physiological roles, and relevant immunological responses. The expression of Wap65-1 and -2 in this study was determined in the face of challenges by Aeromonas salmonicida, infectious hematopoietic necrosis virus (IHNV), and iron-dextran. Immuno-histochemistry (IHC) was employed to localize the major cell types for Wap65-2 expression, and trout leukocytes were isolated and incubated with LPS and OxLDL for comprehending the immunological characteristics of Wap65-2. We demonstrate that Wap65-1 is expressed only in the liver but Wap65-2 is systemically expressed in most organs and tissues. Interestingly, Wap65-1 expression was not significantly changed under A. salmonicida and iron-dextran administration, but was significantly decreased under IHNV. In contrast, Wap65-2 was up-regulated in all challenged groups, however with different expression patterns in the blood and liver. These results suggested that the two paralogs may participate in different biological roles. IHC showed that Wap65-2 antibody had high affinity for leukocyte-like cells, and macrophages but not lymphocytes significantly increased expression under LPS and OxLDL stimulation. These results support the conclusion that trout Wap65-2, not Wap65-1 may have conventional hemopexin functions such as reported in mammals including effects on iron metabolism, inflammation, and acute-phase protein.

Hypothermal stress induced differential expression profiles of the immune response gene, warm-temperature-acclimation associated 65-kDa protein (Wap65), in the liver of fresh water and seawater milkfish, Chanos chanos. FISH & SHELLFISH IMMUNOLOGY 2017; 70:174-184. [PMID: 28882792 DOI: 10.1016/j.fsi.2017.09.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2017] [Revised: 08/26/2017] [Accepted: 09/01/2017] [Indexed: 06/07/2023]
Abstract
The milkfish (Chanos chanos), an important aquaculture species, is intolerant to cold environments. Temperature fluctuations in the environment affect the physiological response, behavior, and survival rate of the fish. The warm-temperature-acclimation associated 65-kDa protein (Wap65) of teleosts was identified after heat shock treatment and has two isoforms. Both the isoforms were involved in the induction of immune responses in fish. They showed high degree of sequence conservation with the mammalian hemopexin and had high affinity for heme, which helped in the neutralization of free-heme and its transport to the liver. In this study, we isolated and characterized the two isoforms of wap65 genes (Ccwap65-1 and Ccwap65-2) from the liver of milkfish. The Ccwap65-1 and Ccwap65-2 are mainly expressed in livers of milkfish. In hypothermal treatment, the expression levels of Ccwap65-2 in the livers of SW and FW milkfish were up-regulated after exposure to low temperature (18 °C) for 12 h and 96 h compared to those in the normal temperature (28 °C) group, respectively. After intraperitoneal injection of lipopolysaccharide (LPS), the expression of Ccwap65-2 was elevated in both SW and FW milkfish, whereas that of Ccwap65-1 was not affected in both the groups. Thus, Ccwap65-2 expressed in the milkfish liver under hypothermal stress was identified as a novel immune biomarker. In addition, according to the transcriptome database, up-regulation of the other immune-response genes indicated increased pathogen infection status under hypothermal stress. Acute increase in the expression of hepatic Ccwap65-2 in response to pathogen infection might lead to better cold tolerance of SW milkfish compared to that of the FW individuals upon cold challenge.

Abstract
One of the most important functions of plasma proteins in vertebrates is their participation in osmotic homeostasis in the organism. Modern concepts about plasma proteins and their capillary filtration are based on a model of large monomeric proteins that are able to penetrate the interstitial space. At the same time, it was revealed that a considerable amount of oligomeric complexes are present in the low-molecular-weight (LM) protein fraction in the extracellular fluids of fishes. The functions of these complexes are unknown. In the present study, we investigated the LM-fraction proteins in the plasma and interstitial fluid (IF) of redfins of the genus Tribolodon. This fish alternatively spends parts of its life cycle in saline and fresh waters. We identified the protein Wap65, serpins and apolipoproteins in this fraction. By combining the methods of 2D-E under native and denaturing conditions with MALDI, we demonstrated that only apolipoproteins formed complexes. We showed that serum apolipoproteins (АроА-I, Аро-14) were present in the form of homooligomeric complexes that were dissociated with the release of monomeric forms of proteins in the course of capillary filtration to IF. Dissociation of homooligomers is not directly correlated with the change in salinity but is correlated with seasonal dynamics. We found that there was a significant decrease in the total protein concentration in IF relative to plasma. Therefore, we suggested that dissociation of homooligomeric complexes from various apolipoproteins supports the isoosmoticity of extracellular fluids relative to capillary wall stabilization through a fluid medium in fish.

Abstract
Water temperature is one of the most important factors in fish physiology; thus, it is important to identify genes that respond to changes in water temperature. In this study, we identified a warm- temperature acclimation-associated 65-kDa protein (Wap65) in the Kumgang fat minnow Rhynchocypris kumgangensis, a small, cold-freshwater fish species endemic to Korea. Kumgang fat minnow Wap65-1 (kmWap65-1) was cloned using polymerase chain reaction (PCR)-based strategies, and was found to be highly homologous with teleost Wap65-1 and mammalian hemopexin, a heme-binding protein that transfers plasma heme into hepatocytes. kmWap65-1 mRNA was expressed mainly in the liver and its expression levels were significantly increased by both short- and long-term exposure to high temperature, which was evaluated by real-time quantitative PCR. Furthermore, the expression levels of kmWap65-1 were highly elevated by exposure to bacterial lipopolysaccharide. These results indicate that kmWap65-1 expression is associated with environmental stresses such as increases in water temperature and bacterial infection. J. Exp.
