Resveratrol Improves the Digestive Ability and the Intestinal Health of Siberian Sturgeon.

ABSTRACT: The lack of detailed information on nutritional requirement results in limited feeding in Siberian sturgeon. In this study, resveratrol, a versatile natural extract, was supplemented in the daily diet, and the digestive ability and microbiome were evaluated in the duodena and valvular intestines of Siberian sturgeon. The results showed that resveratrol increased the activity of pepsin, α-amylase, and lipase, which was positively associated with an increase in the digestive ability, but it did not influence the final body weight. Resveratrol improved the digestive ability probably by distinctly enhancing intestinal villus height. Microbiome analysis revealed that resveratrol changed the abundance and composition of the microbial community in the intestine, principally in the duodenum. Random forests analysis found that resveratrol significantly downregulated the abundance of potential pathogens (Citrobacter freundii, Vibrio rumoiensis, and Brucella melitensis), suggesting that resveratrol may also improve intestinal health. In summary, our study revealed that resveratrol improved digestive ability and intestinal health, which can contribute to the development of functional feed in Siberian sturgeon.

Project description:BackgroundEvolution of sturgeons and paddlefishes (order Acipenseriformes) is inherently connected with polyploidization events which resulted in differentiation of ploidy levels and chromosome numbers of present acipenseriform species. Moreover, allopolyploidization as well as autopolyploidization seems to be an ongoing process in these fishes and individuals with abnormal ploidy levels were occasionally observed within sturgeon populations. Here, we reported occurrence of Siberian sturgeon (Acipenser baerii) male with abnormal ploidy level for this species, accessed its ploidy level and chromosome number and investigate its potential sterility or fertility in comparison with normal individuals of sterlet (A. ruthenus), Russian sturgeon (A. gueldenstaedtii) and Siberian sturgeon (A. baerii).ResultsAcipenser ruthenus possessed 120 chromosomes, exhibiting recent diploidy (2n), A. gueldenstaedtii and A. baerii had ~245 chromosomes representing recent tetraploidy (4n), and A. baerii male with abnormal ploidy level had ~ 368 chromosomes, indicating recent hexaploidy (6n). Genealogy assessed from the mtDNA control region did not reveal genome markers of other sturgeon species and this individual was supposed to originate from spontaneous 1.5 fold increment in number of chromosome sets with respect to the number most frequently found in nature for this species. Following hormone stimulation, the spontaneous hexaploid male produced normal sperm with ability for fertilization. Fertilization of A. baerii and A. gueldenstaedtii ova from normal 4n level females with sperm of the hexaploid male produced viable, non-malformed pentaploid (5n) progeny with a ploidy level intermediate to those of the parents.ConclusionThis study firstly described occurrence of hexaploid individual of A. baerii and confirmed its autopolyploid origin. In addition to that, the first detailed evidence about fertility of spontaneous hexaploid sturgeon was provided. If 1.5 fold increment in number of chromosome sets occurring in diploids, resulted triploids possess odd number of chromosome sets causing their sterility or subfertility due to interference of gametogenesis. In contrast, 1.5 fold increment in number of chromosome sets in naturally tetraploid A. baerii resulted in even number of chromosome sets and therefore in fertility of the hexaploid specimen under study.

Project description:The biology and physiology of Siberian sturgeon reproduction differ substantially from teleost fish. Seminal plasma support and protect the viability, motility and fertilizing capacity of spermatozoa by creating the optimal environment for the storage. The present study for the first time described in-depth proteomic characterization of Siberian sturgeon seminal plasma using gel based and gel-free proteomic approaches: LC-MS/MS, 2DE and 2D blue native (BN)/SDS-PAGE. LC-MS/MS allowed to identify 657 proteins, which were classified according to their functions and pathways. 2DE visualized 339 spots corresponding to 76 unique proteins (almost 60% were present in various proteoforms). For the first time we demonstrated interactions between seminal proteins; four (C1-C4) multiprotein complexes were identified after 2D BN/SDS-PAGE; composed of (C1) serotransferrin-2 (TF) and fish-egg lectin (FEL); (C2) serum albumin 2 (ALB) and retinol-binding protein 4 (RBP4); (C3) ALB and TF (C3) and (C4) apolipoprotein A-I (APOA1), riboflavin-binding protein (RfBP) and myoglobin (MB). BN-SDS-PAGE also revealed that immunoglobulin and TF formed homomultimeric (dimer, trimer, tetramer and pentamer) complexes in seminal plasma. ALB, TF, Beta-Ala-His dipeptidase, glyceraldehyde-3-phosphate dehydrogenase, IGH, APOA1, hemopexin, type-4 ice-structuring protein, FEL, RfBP and glycogen phosphorylase, liver form-like were selected as major seminal plasma proteins. The functional analysis of identified proteins indicated their involvement mainly in immune system process and response to stimulus, metabolism, vesicle-mediated transport, proteolysis, and catherin binding involved in cell-cell adhesion. Moreover, 67 proteins were associated with reproductive processes, including spermatogenesis, fertilization, acrosomal reaction and sperm motility. Comparative proteomic analysis of sturgeon seminal plasma showed common proteins with fish and human and 150 proteins specific for sturgeon which may reflect the specificity of sturgeon reproduction. To conclude, this integrative proteomic view lead to deeper insight into physiological function of seminal plasma and processes occurred in sturgeon reproductive tract.
