Abstract
Mammalian plasma proteins play a key role in maintaining tissue fluid balance because they are retained within capillaries and thus create colloid osmotic pressure. Likewise, fish plasma contain a considerable concentration oligomeric proteins which likely serve a similar role. To elucidate the functions of these oligomeric proteins, we analyzed blood serum (BS) and interstitial fluid (IF) complexes in goldfish from the wild and under experimental conditions using 2D electrophoresis and matrix-assisted laser desorption/ionization (MALDI). We detected protein compounds with MWs ranging from 50 to 155 kDa, organized as oligomeric complexes. The protein compounds consisted of apolipoproteins АроА-I and Аро-14 which are homological to mammalian АроА-I and АроА-II, respectively. The 155-kDa and 50-125-kDa oligomer complexes were located very low-density lipoproteins (LDL) and high-density lipoproteins (HDL) areas on the BS/IF proteomic maps, respectively. The latter resembled mammalian HDL plasma particles by size and contained lipids, so we considered them as HDL particle populations. Investigation of the uniform dissociation/association mechanism for HDL and LDL oligomers in goldfish, from the wild and under critical salinity conditions, showed the "125/110 → 85/60 kDa" reorganization. This was associated with overcoming physiological stress during spawning and under critical salinity conditions. Opposite reorganization "85/60 → 125/110 kDa" was associated with restoration of metabolic processes after stress. The association/dissociation reorganizations promoted equilibration of BS and IF osmolarities in all fish groups. We discuss the connection of these reorganizations with total protein distribution across the capillary wall and salinity, as well as the role of oligomeric apolipoproteins as universal metabolic regulators.

Abstract
In the present study we used a shotgun proteomic approach to identify 54 proteins of rainbow trout ovarian fluid. The study has unravelled the identity of several proteins not previously reported in fish ovarian fluid. The proteome of trout ovarian fluid consists of diverse proteins participating in lipid binding and metabolism, carbohydrate and ion transport, innate immunity, maturation and ovulation processes. Most trout ovarian fluid proteins correspond to follicular fluid proteins of higher vertebrates, but 15% of the proteins were found to be different, such as those related to the immune system (precerebellin-like protein), proteolysis (myeloid cell lineage chitinase), carbohydrate and lipid binding and metabolism (vitellogenins), cell structure and shape (vitelline envelope protein gamma) and a protein with unknown functions (UPF0762 protein C6orf58 homologue). The present study could help in the decoding of the biological function of these proteins and in the discovery of potential biomarkers of oocyte quality.

Abstract
Alpha-1-antitrypsin (AAT) is a highly polymorphic glycoprotein antiprotease, involved in the regulation of human immune response. Beyond some genomic characterization and a few protein characterizations, the function of teleost AAT remains uncertain. In this study we cloned an AAT-like gene from a swamp eel liver identifying four exons and three introns, and the full-length cDNA. The elucidated swamp eel AAT amino acid sequence showed high homology with known AATs from other teleosts. The swamp eel AAT was examined both in ten healthy tissues and in four bacterially-stimulated tissues resulting in up-regulation of swamp eel AAT at different times. Swamp eel AAT transcripts were ubiquitously but unevenly expressed in ten tissues. Further, the mature peptide sequence of swamp eel AAT was subcloned and transformed into E. coli with the recombinant proteins successfully inhibiting bovine trypsin activity. Analysis of recombinant AAT showed equimolar formation of irreversible complexes with proteinases, high stability at pH 7.0-10.0 and temperatures below 55 °C. Serum AAT protein level significantly increased in response to inflammation with AAT anti-sera, and, NF-κB, apolipoprotein A1 and transferrin gene expression were dramatically decreased over 72 h post recombinant AAT injection. Lastly, examination of swamp eel AAT allelic polymorphism identified all alleles in both healthy and diseased stock except allele*g, found only in diseased stock, but without statistical difference between the distribution frequency of allele*g in the two stocks. These results are crucial to our ongoing study of the role of teleost AAT in the innate immune system.

Abstract
The presence of the low-molecular-mass serine protease inhibitor Kazal-type (Spink) is a characteristic feature of vertebrate semen. Its main function is control of the serine protease in the acrosome, acrosin. Here we showed for the first time that Spink is present in the seminal plasma of carp, which have anacrosomal spermatozoa. Using a three-step isolation procedure that consisted in gel filtration and RP-HPLC and re-RP-HPLC, we isolated this inhibitor and identified it as serine protease inhibitor Kazal-type 2 (Spink2), a reproductive-derived member of the Spink family. The cDNA sequence of this inhibitor obtained from carp testis encoded 77 amino acids, including a 17 amino acids signal peptide; this sequence was distinct from fish Kazal-type inhibitors. The mRNA expression analysis showed that Spink2 is expressed predominantly in carp testis and spermatic duct. Immunohistochemical analysis demonstrated its localization in testis in Sertoli, Leydig and germ cells at all developmental stages (with the exception of spermatozoa) and in the epithelium of the spermatic duct. Aside from strong inhibition of trypsin, this inhibitor acts strongly against subtilisin and possesses bacteriostatic activities against Lactobacillus subtilis, Escherichia coli and Aeromonas hydrophila. The localization of Spink2 in carp reproductive tract suggests an important function in spermatogenesis and in maintenance of the microenvironment in which sperm maturation occurs and sperm are stored. Our results suggest that Spink2 from carp seminal plasma may play a role in antibacterial semen defense, protecting semen against unwanted proteolysis within the reproductive tract.

Abstract
BACKGROUND Methylmercury (MeHg) is an environmental contaminant most known for its severe neurotoxic effects. Although accumulation of MeHg tends to be several folds higher in kidney compared to other tissues, studies on nephrotoxic effects are almost non-existing. In this study we aim to investigate the toxicity of dietary MeHg in kidney of Atlantic salmon (Salmo salar). MATERIAL AND METHODS Atlantic salmon were exposed to dietary MeHg for a period of 8 weeks, before the fish were euthanized and kidney was sampled for proteomic and real time RT-PCR analysis, as well as for mercury determination. Protein separation was done with 2-D PAGE, and differentially regulated spots were picked for analysis using liquid chromatography MS/MS analysis. Moreover, whole blood and liver tissue were sampled for mercury determination and real time RT-PCR (liver). RESULTS MeHg exposed fish accumulated significantly more mercury (Hg) than control fish. The proteomic analysis revealed differential abundance of 26 spots in the kidney, and 14 of these protein spots were successfully identified. The proteins identified indicated effects of MeHg on; metabolism, inflammation, oxidative stress, protein-folding, and cell-structural components. Gene expression analysis of selected markers revealed few differentially regulated transcripts in kidney and liver in the exposed fish compared to the control fish. However, the affected transcripts indicated a disruption in the expression of two metabolic markers due to MeHg exposure in liver. CONCLUSION This study suggests that dietary MeHg has similar effects in kidney as previously shown for other tissues in fish. The effects observed were in markers for oxidative stress, inflammation and energy metabolism. The identification of proteomic markers in this study provides a basis for a better understanding of MeHg-induced nephrotoxicity in fish.

Abstract
Sperm proteins in the seminal plasma and spermatozoa of teleostean and chondrostean have evolved adaptations due to the changes in the reproductive environment. Analysis of the composition and functions of these proteins provides new insights into sperm motility and fertilising abilities, thereby creating possibilities for improving artificial reproduction and germplasm resource conservation technologies (e.g. cryopreservation). Seminal plasma proteins are involved in the protection of spermatozoa during storage in the reproductive system, whereas all spermatozoa proteins contribute to the swimming and fertilising abilities of sperm. Compared to mammalian species, little data are available on fish sperm proteins and their functions. We review here the current state of the art in this field and focus on relevant subjects that require attention. Future research should concentrate on protein functions and their mode of action in fish species, especially on the role of spermatozoa surface proteins during fertilisation and on a description of sturgeon sperm proteins.

Abstract
The main serine proteinase inhibitors of rainbow trout (Oncorhynchuss mykiss) and common carp (Cyprinus carpio) blood plasma were isolated and purified. The investigated inhibitors, alpha(1)-proteinase inhibitor (alpha(1)-PI) and antithrombin III (AT III), act by forming stable complexes with target proteinases. The association rate constants k (on) for the interaction of fish plasma inhibitors with several serine proteinases have been determined: k (on) for both carp and rainbow trout alpha(1)-PI were >10(7) M(-1) s(-1) for human neutrophil elastase, and in the case of bovine trypsin and chymotrypsin k (on) values were 2.0-5.2 x 10(6) M(-1) s(-1). Association rate constants k (on) for the interaction of carp and rainbow trout AT III with bovine trypsin and thrombin were about 1.3 x 10(4)-7.9 x 10(5) M(-1) s(-1) without and >10(7) M(-1) s(-1) in presence of heparin; so antithrombins require the presence of heparin to become effective proteinase inhibitors. The high degree of homology of the estimated amino acid sequences of fish inhibitors reactive site loops confirms their similarity with other proteinase inhibitors from the serpin family.

Abstract
Methods for the isolation and quantification of infectious pancreatic necrosis virus (IPNV) from ovarian and seminal fluids of Atlantic salmon are described. Both have utility for the non-lethal detection of IPNV in mature broodstock and for research into vertical transmission. Two experiments are described to check the efficiency of an elution method for the removal of IPNV from milt. The isolation rate for ovarian fluid of females was generally higher than that for seminal fluid of males from the same populations. In IPNV milt mixing experiments up to 99.98% of available IPNV adsorbed to Atlantic salmon spermatozoa and 20-100% of virus eluted using a variety of procedures. Titration of virus from naturally infected milt can be useful in estimating the relative vertical transmission risk from male broodstock.

Abstract
Using a three-step procedure, we purified (79 and 51.6-fold to homogeneity) and characterized the two isoforms (a and b) of alpha1-proteinase inhibitor-like protein from carp seminal plasma. The isoforms have molecular masses of 55.5 and 54.0 kDa, respectively. These inhibitors formed SDS-stable complexes with cod and bovine trypsin, chymotrypsin and elastase. The thirty-three amino acids within the reactive loop SLPDTVILNRPFLVLIVEDTTKSILFMGKITNP were identified for isoform b. The same first ten amino acids were obtained for isoform a, and this sequence revealed 100% homology to carp alpha1-proteinase inhibitor (alpha1-PI) from perimeningeal fluid. Both isoforms of alpha1-PI are glycoproteins and their carbohydrate content was determined to be 12.6 and 12.1% for a and b, respectively. Our results indicated that alpha1-PI is one of the main proteins of carp seminal plasma. Using polyclonal anti-alpha1-PI antibodies, alpha1-PI was for the first time localized to the carp testis. The presence of alpha1-PI in testis lobules and in the area surrounding spermatides suggests that this inhibitor may be involved in the maintenance of testis connective tissue integrity, control of spermatogenesis or protection of tissue and spermatozoa against unwanted proteolysis. Since similar alpha1-PI has been identified in rainbow trout semen it can be suggested that the presence of alpha1-PI in seminal plasma is a common feature of cyprinid and salmonid fish.
