Project description:Milk, renowned for its nutritional value, harbours bioactive compounds, including lactoferrin (Lf) [1], immunoglobulins, and functional proteins suggesting broader functionalities beyond nutrition. Lf, an iron glycoprotein, exhibits antimicrobial properties against bacteria, fungi, and viruses."In"this st"dy, Immune Powder (a functional dairy formulation) and Fractionated Milk Protein (FMP; a blend of bioactive proteins isolated from skim milk) containing Lf, zinc, and immunoglobulins produced by Ausnutria Australia Dairy Pty Ltd were evaluated for their broad spectrum pharmacological activity. In particular, the study aims to investigate the antibacterial (against pathogenic Escherichia coli), prebiotic (promoting Lactobacillus delbrueckii growth), anti-inflammatory (against RAW264.7 macrophages), and antiviral (against human coronavirus 229E, HCoV-229E cultured on MCR-5 cells) effects of the formulations. In addition, the impact of simulated gastric digestion on the efficacy of the formulations was explored. LCMS-based proteomics analysis was implemented to unveil cellular and molecular mechanisms underlying antiviral activity. The Immune Powder demonstrated antibacterial activity against E. coli (up to 99.74 ± 11.47% inhibition at 62.5 mg/mL), coupled with prebiotic action (10.84 ± 2.2 viability fold change at 125 mg/mL), albeit diminished post-digestion (p <0.01). The Immune Powder effectively mitigated inflammation by reducing NO production, with efficacy declining post-digestion (p < 0.0001). The potential antiviral activity of Immune Powder against HCoV-229E also shown an increase of 2.62 ± 0.42 in cell viability when treated at 500 µg/mL. Similarly, FMP exhibited antibacterial potency pre-digestion at high concentration (95.56 ± 1.23% inhibition at 125 mg/mL), and post-digestion at lower doses (61.82 ± 5.58% inhibition at 3906.25 µg/mL). FMP also shown enhanced prebiotic activity post-digestion (p < 0.0001), anti-inflammation pre-digestion, and significant antiviral activity against HCoV-229E (1.72 ± 0.52 cell viability fold change). The proteomics study suggested both formulas shared similar antiviral mechanism by inhibiting scavenger receptor binding and ECM interaction.

Project description:To further investigate the potential molecular basis of the therapeutic effects of the mixture of salvianolic acids from Salvia miltiorrhiza and total flavonoids from Anemarrhena asphodeloides (MSTF) on sulfur mustard (SM) damage, gene expression analysis was conducted on rats liver tissues using microarrays. Rats were randomly assigned to one of the three following treatment groups (10 rats per group): normal control, SM and SM + MSTF. SM was dissolved in propylene glycol. The SM was applied with subcutaneous injection as a single dose of 3.5 mg/kg body weight equivalent to 0.7 LD50. The equivalent volume of solvent was given to control rats. MSTF (120 mg/kg body weight/day) dissolved in double distilled water were administered intragastrically to the rats 1 h after SM treatment. Twenty-four hours following SM treatment, the rats were subjected to anesthesia and then sacrificed by cervical dislocation. Liver was dissected out from each animal. 3-4 of these liver tissues were processed for the microarray experiment.

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), and Podot1 knockout strain (ΔPodot1) in different carbon sources. The deletion of Podot1 downregulated genes involved in the septin complex, extracellular region, and interspecies interaction between organisms when strains were cultivated with 2% glucose as carbon sources, and downregulated genes involved in cellulase activity, cellulose binding, glucosidase activity, and polysaccharide catabolic process when strains were cultivated with 1% microcrystalline cellulose and 1% wheat bran as carbon sources. We find the extracellular region was downregulated under both different carbon sources in ΔPodot1. This study provides the information that PoDot1 function are required in mycelial development and hydrolase activity of P. oxalicum.

Project description:Bifidobacterium infantis is associated with the gut microbiota of breast-fed infants. B. infantis promotes intestinal barrier and immune function through several proposed mechanisms, including interactions between their surface polysaccharides, the host, and other gut microorganisms. Dairy foods and ingredients are some of the most conspicuous food-based niches for this species and may provide benefits for their delivery and efficacy in the gut. Milk phospholipid (MPL)-rich ingredients have been increasingly recognized for their versatile benefits to health, including interactions with the gut microbiota and intestinal cells. Therefore, our objective was to investigate the capacity for MPL to promote survival of B. infantis during simulated digestion and to modulate bacterial polysaccharide production. To achieve these aims, B. infantis was incubated with or without 0.5% MPL in de Man, Rogosa, and Sharpe (MRS) media at 37 °C under anaerobiosis. Survival across the oral, gastric, and intestinal phases using in vitro digestion was measured using plate count, along with adhesion to goblet-like intestinal cells. MPL increased B. infantis survival at the end of the intestinal phase by at least 7% and decreased adhesion to intestinal cells. The bacterial surface characteristics, which may contribute to these effects, were assessed by ζ-potential, changes in surface proteins using comparative proteomics, and production of bound polysaccharides. MPL decreased the surface charge of the bifidobacteria from –17 to –24 mV and increased a 50 kDa protein (3-fold) that appears to be involved in protection from stress. The production of bound polysaccharides was measured using FTIR, HPLC, and TEM imaging. These techniques all suggest an increase in bound polysaccharide production at least 1.7-fold in the presence of MPL. Our results show that MPL treatment is positively correlated with increased survival during simulated digestion, a stress resistance surface protein, and bound polysaccharide production of B. infantis, suggesting its use as a functional ingredient to enhance probiotic and postbiotic effects.

Project description:Dendrobium catenatum (D. catenatum) has long been used as an important medicinal herb in oriental medicine. Polysaccharide, flavonoid, and alkaloid are the major active ingredients, the production and accumulation of which are frequently affected by many environmental factors including water, temperature, and mycorrhizal fungus. However, how phytohormones frequently used in orchid tissue culture regulate the production of active components in D. catenatum is far from clear. Here, major medicinal metabolites were comparatively analyzed in 2-month-old D. catenatum seedlings exposed to phytohormones (0.1 mg/L NAA and/or 1.0 mg/L 6-BA) for three weeks, and eight transcriptomes (two replicates each) corresponding to the treatments were generated. Results demonstrated that the phytohormones triggered transcriptional reprograming, analysis of which revealed a tight association of β-glucosidase (BGLU) expression with the accumulation of polysaccharide. Subsequently, a second RNA-sequencing was further conducted to reveal that a relatively short period (2 w) of varied concentrations of 6-BA application might initially reduce BGLU expression and polysaccharide content and then increase their levels with prolonged treatments (4 w). The RNA-seq data was reconfirmed by functional analysis that 6-BA induced polysaccharide production, while knockdown of BGLU2L resulted in decreased polysaccharide levels. Therefore, the present study clearly demonstrated that BGLU is a key regulator for polysaccharide production and that it is extremely susceptible to NAA and 6-BA treatments in D. catenatum.
