Sulfated Galactans from Gracilaria fisheri with Supplementation of Octanoyl Promote Wound Healing Activity In Vitro and In Vivo. Macromol Biosci 2022; 22:e2200172.

Abstract
Sulfated galactans (SG) isolated from Gracilaria fisheri is partially degraded (DSG), and subsequentially supplemented with octanoyl (DSGO) and sulfate (DSGS) groups. The molecular weights of DSG, DSGO, and DSGS are 7.87, 152.79, and 97.07 kDa, respectively. The modification is confirmed using FTIR and NMR, while in vitro wound healing activity is assessed using scratched wound fibroblasts. The results reveal that DSGO exhibits highest percentage of wound closure in scratched fibroblast L929 cells. Furthermore, DSGO is able to promote proliferation and accelerate migration of scratched fibroblasts, which correspond to the regulation of proteins and mRNA (Ki67, p-FAK, vimentin, and E-cadherin) determined by Western blotting and qPCR analysis. The superior wound healing activity of DSGO is also confirmed in excision wound of rats. The results demonstrate that DSGO significantly enhances the percentage of wound closure, re-epithelialization, and collagen arrangement, increases α-smoth muscle actin (α-SMA) and vimentin expression, and decreases that of tumor necrosis factor-α (TNF-α) at the wound site. The results suggest that degraded SG supplemented with medium-chain fatty acids of octanoyl group may pass through the membrane, subsequently activating the mediators associated with proliferation and migration of fibroblasts, which can potentially lead to the promotion of wound healing activity.

Abstract
Only a mere fraction of the huge variety of human pathogenic viruses can be targeted by the currently available spectrum of antiviral drugs. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak has highlighted the urgent need for molecules that can be deployed quickly to treat novel, developing or re-emerging viral infections. Sulfated polysaccharides are found on the surfaces of both the susceptible host cells and the majority of human viruses, and thus can play an important role during viral infection. Such polysaccharides widely occurring in natural sources, specifically those converted into sulfated varieties, have already proved to possess a high level and sometimes also broad-spectrum antiviral activity. This antiviral potency can be determined through multifold molecular pathways, which in many cases have low profiles of cytotoxicity. Consequently, several new polysaccharide-derived drugs are currently being investigated in clinical settings. We reviewed the present status of research on sulfated polysaccharide-based antiviral agents, their structural characteristics, structure-activity relationships, and the potential of clinical application. Furthermore, the molecular mechanisms of sulfated polysaccharides involved in viral infection or in antiviral activity, respectively, are discussed, together with a focus on the emerging methodology contributing to polysaccharide-based drug development.

Abstract
The outbreak of acute hepatopancreatic necrosis disease (AHPND) has caused great economic losses to the shrimp culture sector. However, the use of antibiotics to fight this disease has resulted in negative impacts on human health and the environment. Thus, the use of natural alternatives to antibiotics may be a better solution. In this study, four Bacillus species obtained from the guts of shrimps (Fenneropenaeus penicillatus and Penaeus monodon) showed antimicrobial activity against the AHPND-causing Vibrio parahaemolyticus strain 3HP using the cross-streaking and agar spot methods. Two of the Bacillus isolates, B2 and BT, also showed good probiotic properties, exhibiting tolerance to bile, good adhesion to shrimp mucus, non-hemolytic, susceptibility to antibiotics and being safe towards hosts. Moreover, a seaweed-probiotic blend (a combination of Bacillus B2 and 20 mg/ml of the red seaweed Gracilaria sp.) exhibited synergistic in vitro inhibition against V. parahaemolyticus strain 3HP, with an observed inhibition zone of 5.0 mm. The broth co-culture experiment results further indicated that the seaweed-probiotic blend inhibited V. parahaemolyticus through competitive exclusion. The in vivo challenge trials also confirmed that this seaweed-probiotic blend significantly reduced the mortality of shrimps post-challenge with the AHPND-causing V. parahaemolyticus strain 3HP (p < 0.05) compared to the negative control (mortality rate = 13.88% vs 72.19%). Thus, this seaweed-probiotic blend may serve as an alternative to antibiotics in controlling the outbreak of AHPND.

Abstract
The present study was conducted to evaluate the effects of marine polysaccharides from seaweed Enteromorpha on growth performance, immune responses, intestinal morphology and microbial community in the banana shrimp Fenneropenaeus merguiensis. Two thousand and four hundred juvenile shrimps with an average body weight of 2.18 ± 0.06 g were fed for 42 d with diets containing different levels of Enteromorpha polysaccharides (EPS): 0 (control), 1, 2 and 3 g/kg as treatment groups, each of group was replicated three times with two hundred shrimps per replicate. Dietary supplementation of 1 g/kg EPS showed a consistent improvement in the final weight, weight gain, average daily gain rate (ADGR) and specific growth rate (SGR) (P < 0.05), while showed a decrease in the feed conversion ratio (FCR) of shrimp (P < 0.05). Besides, the total anti-oxidative capacity (T-AOC), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione S-transferase (GST), lysozyme (Lyz), alkaline phosphatase (ALP), and phenoloxidase (PO) activities in hemolymph were enhanced by dietary supplementation of 1 g/kg EPS (P < 0.05), while it reduced the hemolymph MDA content (P < 0.05). Shrimp fed 1 g/kg EPS supplemented diets up-regulated FmLyz, FmSOD5 and FmCLAP gene expression level of hepatopancreas and gill (P < 0.05), and also improved the intestinal FmLC2, FmLyz, FmSOD5 and FmCLAP gene expression levels (P < 0.05). In addition, shrimp fed diets containing 1 g/kg EPS increased the villus width (P < 0.05) and resulted in a higher villus surface area (P < 0.05). According to 16S rRNA sequencing results, dietary supplementation of 1 g/kg EPS tended to increase the relative abundance of Firmicutes at phylum level (P = 0.07) and decrease the relative abundance of Vibrio at genus level (P = 0.08). There was a significant positive correlation between the relative abundance of Firmicutes and mRNA expression of intestinal immune-related genes (P < 0.05). These findings revealed that dietary 1 g/kg EPS could improve growth performance, enhance nonspecific immunity and modulate intestinal function of banana shrimp F. merguiensis.

Abstract
Live food organisms like Artemia have been used for delivery of different substances such as nutrients, probiotics and immune-stimulants to aquatic animals. Previously, we reported that sulfated galactans (SG) from the red seaweed Gracilaria fisheri (G. fisheri) increased immune activity in shrimp. In the present study we further investigated the capacity and efficiency of bioencapsulation of SG in adult Artemia for delivery to tissues and potentially boosting the expression of immune genes in post larvae shrimp. SG were labelled with FITC (FITC-SG) for in vivo tracking in shrimp. Bioencapsulation of adult Artemia with FITC-SG (0-100 μg mL-1) was performed and the fluorescence intensity was detected in the gut lumen after enrichment periods of 30 min, 1 h, 2 h, 6 h and 24 h. The results showed the Artemia took up SG over time in a concentration-dependent manner. Shrimp were fed with the bioencapsulated Artemia (FITC-SG, 20 μg mL-1) and the shrimp were evaluated under a stereo-fluorescent microscope. At 24 h after administration, FITC-SG was located in gills and hepatopancreas and also bound with haemocytes. With daily SG administration, the genes IMD, IKKβ were up-regulated (after 1 day) while genes dicer and proPO-I were up-regulated later (after 7 days). Moreover, continued monitoring of shrimp fed for 3 consecutive days only with SG at the dose of 0.5 mg g-1 BW showed increases in the expression of IMD, IKKβ genes on day 1 and which gradually declined to normal levels on day 14, while the expression of dicer and proPO-I was increased on day 3 and remained high on day 14. These results demonstrate that bioencapsulation of SG in adult Artemia successfully delivers SG to shrimp tissues, which then bind with haemocytes and subsequently activate immune genes, and potentially increase immunity in shrimp. In addition, the present study suggests that a 3-consecutive-day regimen of SG supplemented in Artemia (0.5 mg g-1 BW) may boost and sustain the enhanced immune functions in post larvae shrimp.

Abstract
The use of antibiotics in the feeds of cultivable aquatic animals has been generally practised to reduce infectious diseases as well as to improve the survival and growth. In recent years, many countries ban to aquatic animals due to the use of large amount of antibiotics and chemotherapies, thus alternative novel strategies are need to promote the growth of aquatic animals and control the pathogens. Dietary supplementation of marine-derived polysaccharides (MDPs) is one of the potential substitutes for antibiotics in aquatic animal feeds. Recently, the use of dietary MDPs in the aquaculture animals has been focused with much interest. In aquaculture, MDPs are used as prebiotic substance which is mostly accepted as a nutritional component for improving the growth performance and health conditions. Hence, present review is a comprehensive and an updated collection of available research reports on different MDPs (alginate, fucoidan, carrageenan, laminarin, ulvan, galactan, agar, chitin and chitosan), route of administration, dosage and applications for improving aqua feeds with emphasis on its effects on growth, biochemical indices, immune response, gut microbiota and disease resistance of aquaculture animals. This review describes the sustainability of global aquaculture production by providing a best alternative to harmful antibiotics, thereby meeting the emerging consumer demand for antibiotic-free aquatic food products.

Abstract
Viral envelope proteins play an important role in facilitating the attachment of viruses to the surface of host cells. Here, we investigated the binding of White Spot Syndrome Virus (WSSV) VP37 to haemocytes of whiteleg shrimp, Litopenaeus vannamei. Three versions of recombinant VP37 proteins, including full length VP37 (VP37(1-281)), C-terminal domain VP37 (VP37(111-281)) and C-terminal domain disrupted VP37 (VP37(1-250)) were individually expressed and tested for their haemocytes binding ability. Through an ELISA-based binding assay, we found that VP37(111-281) bound to shrimp haemocytes in a similar way to VP37(1-281), while VP37(1-250) exhibited a significantly weaker binding. This suggests that the C-terminal domain of VP37 is required for the binding of VP37 to shrimp haemocytes. Furthermore, we found that the binding of VP37 to shrimp haemocytes was impaired by pre-incubation of VP37 with sulfated galactan (SG), a sulfated polysaccharide derived from red seaweed (Gracilaria fisheri). Previously, it has been shown that a type of sulfated polysaccharide, heparin, is also present in L. vannamei. To investigate the role of heparin as a receptor for VP37, the binding of VP37 to porcine heparin, whose structure is similar to that found in L.vannamei, was investigated in a Surface Plasmon Resonance (SPR) system. The results showed that VP37 bound strongly to heparin with binding affinity (KD) of 1.0 μM and the binding was significantly blocked by SG. These findings have lead us to propose that the attachment of WSSV might be mediated by the interaction between VP37 and a heparin-like molecule presented on the shrimp cells.

Abstract
Cholangiocarcinoma (CCA) is increasing in incidence worldwide and is resistant to chemotherapeutic agents, making treatment of CCA a major challenge. Previous studies reported that natural sulfated polysaccharides (SPs) disrupted growth factor receptor activation in cancer cells. The present study, therefore, aimed at investigating the antiproliferation effect of sulfated galactans (SG) isolated from the red seaweed Gracilaria fisheri (G. fisheri) on CCA cell lines. Direct binding activity of SG to CCA cells, epidermal growth factor (EGF) and epidermal growth factor receptor (EGFR) were determined. The effect of SG on proliferation of CCA cells was investigated. Cell cycle analyses and expression of signaling molecules associated with proliferation were also determined. The results demonstrated that SG bound directly to EGFR. SG inhibited proliferation of various CCA cell lines by inhibiting EGFR and extracellular signal-regulated kinases (ERK) phosphorylation, and inhibited EGF-induced increased cell proliferation. Cell cycle analyses showed that SG induced cell cycle arrest at the G0/G1 phase, down-regulated cell cycle genes and proteins (cyclin-D, cyclin-E, cdk-4, cdk-2), and up-regulated the tumor suppressor protein P53 and the cyclin-dependent kinase inhibitor P21. Taken together, these data demonstrate that SG from G. fisheri inhibited proliferation of CCA cells, and its mechanism of inhibition is mediated, to some extent, by inhibitory effects on EGFR activation and EGFR/ERK signaling pathway. SG presents a potential EGFR targeted molecule, which may be further clinically developed in a combination therapy for CCA treatment.

This paper investigates the efficacy of Gracilaria corticata, Saccharomyces cerevisiae and gamma irradiation WSSV as immunostimulants to white shrimp Litopenaeus vannamei. Seven hundred and twenty healthy shrimp SPF L. vannamei subadult with average weight of 10 ± 1.02 g were collected and divided into 8 groups. The first group (T1) was fed with commercial pellet, the second group (T2) fed with S. cerevisiae (2 g/kg), the third group (T3) fed with G. corticata powder mixed with shrimp feed (2 g/kg) and, finally, the fourth group (T4) was fed with commercial pellet and injected intramuscularly gamma irradiant WSSV (1 μl/gbw) for 10 days. The shrimps were then injected with WSSV and maintained for 25 days. The positive control group for each treatment was maintained in the same manner but without injection with WSSV. Moreover, survival rate and immune parameters such as total hemocyte count (THC), total protein plasma (TPP), superoxide dismutase (SOD) activity, peroxidase (POD) activity and phenoloxidase activity (PO) were determined. Results indicated that the survival rates for groups T4, T3 T2 and T1 were 57.05 ± 3.52%, 22.5 ± 0.5%, 15 ± 1.05% and 00.0 ± 0%, respectively. Ultimately, at the end of the study the shrimp group T4 showed higher hematological data: THC, TPP, SOD, POD and PO. The study concluded that gamma irradiant WSSV is effective immunostimulants in shrimp L. vannamei and the immunity has better performances than those of the G. corticata and S. cerevisiae.

Abstract
Previous studies demonstrated that sulfated galactans (SG) from Gracilaria fisheri (G. fisheri) exhibit immunostimulant activity in shrimp. The present study was conducted to test the hypothesis that SG stimulates signaling molecules of the immune response of shrimp by binding to receptors on the host cell membrane. Accordingly, we evaluated the ability of SG to bind to shrimp haemocytes and showed that SG bound to the shrimp haemocyte membrane (SHM), potentially to specific receptors. Furthermore, this binding was associated with an activation of immune response genes of shrimp. Data from confocal laser scanning micrographs revealed that FITC-labeled SG bound to haemocytes. Far western blot analysis demonstrated that SHM peptides, with molecular sizes of 13, 14, 15, 17, and 25 kDa, were associated with SG. Peptide sequence analysis of the isolated bands using LC-MS/MS and NCBI blast search revealed the identity of the 13, 14, and 17 kDa peptides as lipopolysaccharide and β-1,3-glucan binding protein (LGBP). SG induced the expression of immune related genes and downstream signaling mediators of LGBP including IMD, IKKs, NF-κB, antimicrobial peptides (crustin and PEN-4), the antiviral immunity (dicer), and proPO system (proPO-I and proPO-II). A LGBP neutralizing assay with anti-LGBP antibody indicated a decrease in SG-induced expression of LGBP downstream signaling mediators and the immune related genes. In conclusion, this study demonstrated that the SG-stimulated immune activity in haemocytes is mediated, in part, through the LGBP, and IMD-NF-κB pathway.
