Braz J Microbiol 2024:10.1007/s42770-024-01372-4. [PMID: 38789906 DOI: 10.1007/s42770-024-01372-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Accepted: 05/06/2024] [Indexed: 05/26/2024] Open
Abstract
This study aims to investigate the anti-obesity properties of lactic acid bacteria (LAB) isolated from fermented dairy products such as "Airag" and "Khoormog" in Mongolia. These traditional dairy products are widely used in Mongolia and believe in having potential probiotic, anti-diabetes, anti-cancer, and anti-tuberculosis properties and are made from unheated two-humped camel milk and mare milk, respectively. We chose three LAB strains based on their probiotic characteristics, including tolerance of gastric and bile acids. Then we checked the anti-obesity activity of probiotic strains in vivo. An animal model was evaluated in twenty male C57BL/6J mice by inducing obesity with a high-fat diet (HFD), which was divided into five groups: regular diet group (Negative control), HFD group (Positive control), HFD with Lacticaseibacillus paracasei X-1 (X-1), Lacticaseibacillus paracasei X-17 (X-17), and Limosilactobacillus fermentum BM-325 (BM-325). For six weeks, 5 × 109 colony-forming units (CFU) of bacteria were given orally to the LAB-fed groups. Fasting blood glucose (FBG), lipid profiles, organ index, and organ morphology were all measured. The probiotic strains suppressed growth in adipose cell volume, stabilized FBG, reduced liver cell degeneration, and slowed HFD-induced body weight gain. The results suggest that some strains increase general metabolism while lowering body weight.

Abstract
The main objective of this research was to identify potential probiotic candidates belonging to the Bacillus species that could demonstrate tolerance to bile salt and acidic conditions. The study focused on isolating Bacillus strains from the intestine of marine fish-Microstomus kitt. The isolation process involved the use of selective MRS media through the pour plate method. After 24 h, one particular isolate was identified based on its morphological and biochemical traits as Bacillus species. To confirm the identity, molecular characterization of the 16S RNA from the isolated strain was performed, and the sequence analysis verified it as Bacillus subtilis strain ACL_BS 001. With the molecular confirmation, the next step was to assess the probiotic characteristics of this B. subtilis strain. Various tests were conducted to evaluate its acid/pH tolerance, NaCl tolerance, and bile salt tolerance. The results indicated that B. subtilis exhibited high viability percentages even under acidic pH, in the presence of 1.5% bile salt, and at high salt concentrations. Subsequently, we investigated the strain's ability to produce lipase, an important enzyme with potential industrial applications. B. subtilis was grown in MRS agar amended with olive oil as a lipase substrate. After incubation, the presence of lipase activity was confirmed, and the enzymatic assay revealed a significant lipase enzyme activity of 100.23 µmoles/ml of the sample. In conclusion, the study successfully isolated and identified B. subtilis from the intestine of Microstomus kitt, and the strain exhibited promising probiotic characteristics, including resistance to bile salt and acidic conditions. Furthermore, the strain was found to produce lipase, which opens up possibilities for future research focusing on isolating and purifying the lipase from this potential probiotic B. subtilis strain.

Abstract
This work aimed to study the antidiabetic effect of encapsulated fucoxanthin with porous starch (PS) in streptozotocin and nicotinamide-induced type 2 diabetic mice. Fucoxanthin was extracted and purified from Sargassum angustifolium and encapsulated in porous starch (PS). Diabetic mice groups were gavaged daily with fucoxanthin (400 mg/kg), either free or encapsulated into PS, and metformin (50 mg/kg) for three weeks. The results exhibited that the fucoxanthin and fucoxanthin-loaded PS markedly prevented the weight gain in treated groups (p < .05). Moreover, both free and encapsulated fucoxanthin could decrease the fasting blood glucose and increase the plasma insulin level similar to metformin (p < .05). In addition, total cholesterol, triglyceride, and low-density lipoprotein were lower in the treated groups. These results confirm antiobesity effect of fucoxanthin by regulating lipid profile parameters. Moreover, the histopathology evaluation of pancreatic tissue in diabetic mice exhibited that oral administration of metformin and fucoxanthin caused regeneration of pancreatic beta cells. This study revealed the healthy effect of seaweed pigment as a suitable bioactive compound which can be used in functional foods for natural diabetes therapy.

Abstract
Targeting cancer cells with small nanoparticles is a novel and promising approach to cancer therapy. Breast cancer is the most common cancer afflicting women worldwide. In the present study, silver nanoparticles (AgNPs) were synthesized using the aqueous extract of the marine alga Capsosiphon (C.) fulvescens, and the cytotoxicity and anti-cancer activities of the nanoparticles against MCF-7 breast cancer cells were analyzed. Nanoparticle formation was confirmed by solution color change and UV-Vis spectroscopy. The size and distribution of the C. fulvescens-biosynthesized silver nanoparticles (CfAgNPs) were then examined using various analytical methods; the particle size was around 20-22 nm and spherical in shape with no agglomeration. Cytotoxicity analysis revealed that the inhibitory concentration (IC50) of CfAgNPs was 50 μg/ml. MCF-7 cell viability decreased with increasing concentrations of CfAgNPs. MCF-7 cells were evaluated for morphological changes before and after treatment with the CfAgNPs; cells treated with C. fulvescens aqueous algal extract (without CfAgNPs) showed irregular confluent aggregates with round polygonal cells, similar to the untreated control. Tamoxifen- (TMX) and CfAgNPs-treated cells show significant morphological changes. An apoptosis study was conducted using 4',6-diamidino-2-phenylindole (DAPI) staining, in which CfAgNP-treated MCF-7 cells generated bright blue fluorescence and shortened, disjointed chromatin was evident; control cells displayed less bright fluorescence. Flow cytometry analysis revealed that the percentage of cells in late apoptosis was high following treatment with TMX (77.2%) and CfAgNP (74.6%). A novel anti-cancer agent, developed by generating silver nanoparticles from C. fulvescens extract, showed strong cytotoxic activity against MCF-7 cells.

Abstract
Aging-induced cognitive dysfunction can be regulated by probiotics through bidirectional communication with the brain. This study aimed to investigate whether Capsosiphon fulvescens glycoproteins (Cf-hGP) enhanced probiotic-induced improvement of memory in aged rats and the underlying mechanism in the dorsal hippocampus. Cf-hGP were isolated using lectin resin. Cf-hGP (15 mg/kg/day) and/or Lactobacillus plantarum (L. plantarum) (109 CFU/rat/day) were orally administered once a day for 4 weeks. Co-treatment with Cf-hGP and L. plantarum synergistically improved spatial memory in aged rats, which was overturned by functional blocks of brain-derived neurotrophic factor (BDNF) signaling. Increases in BDNF expression and nuclear factor erythroid 2-related factor 2 (Nrf2) phosphorylation were accompanied by mono- and/or co-administration in the dorsal hippocampus, while c-Jun N-terminal kinase (JNK) phosphorylation and glucose-regulated protein 78 expression were decreased. These synergistic effects were downregulated by blocks of BDNF/Nrf2-mediated signaling. In particular, co-treatment, not mono-treatment, reduced phosphorylation of eukaryotic elongation factor 2 (eEF2) regulated by eEF2 kinase and protein phosphatase 2A. Additionally, co-treatment downregulated the interaction between eEF2 kinase and JNK. These data demonstrated that cognitive impairment in aged rats was synergistically diminished by co-treatment with Cf-hGP and L. plantarum through BDNF-mediated regulation of Nrf2 and eEF2 signaling pathways in the dorsal hippocampus.

Abstract
Endoplasmic reticulum (ER) stress is involved in various neurodegenerative disorders. We previously found that Capsosiphon fulvescens (C. fulvescens) crude proteins enhance spatial memory by increasing the expression of brain-derived neurotrophic factor (BDNF) in rat dorsal hippocampus. The present study investigated whether the chronic oral administration of hydrophilic C. fulvescens glycoproteins (Cf-hGP) reduces aging-induced cognitive dysfunction by regulating ER stress in the dorsal hippocampus. The oral administration of Cf-hGP (15 mg/kg/day) for four weeks attenuated the aging-induced increase in ER stress response protein glucose-regulated protein 78 (GRP78) in the synaptosome of the dorsal hippocampus; this was attenuated by the function-blocking anti-BDNF antibody (1 μg/μL) and a matrix metallopeptidase 9 inhibitor 1 (5 μM). Aging-induced GRP78 expression was associated with glycogen synthase kinase-3 beta (GSK-3β) (Tyr216)-mediated c-Jun N-terminal kinase phosphorylation, which was downregulated upon Cf-hGP administration. The Cf-hGP-induced increase in GSK-3β (Ser9) phosphorylation was downregulated by inhibiting tyrosine receptor kinase B and extracellular signal-regulated kinase (ERK)1/2 with cyclotraxin-B (200 nM) and SL327 (10 μM), respectively. Cf-hGP administration or the inhibition of ER stress with salubrinal (1 mg/kg, i.p.) significantly decreased aging-induced spatial memory impairment. These findings suggest that the activation of the synaptosomal BDNF-ERK1/2 signaling in the dorsal hippocampus by Cf-hGP attenuates age-dependent ER stress-induced cognitive dysfunction.

Abstract
Brown algae and its carotenoids have been shown to have a positive influence on obesity and its comorbidities. This study evaluated the effect of Undaria pinnatifida and fucoxanthin on biochemical, physiological and inflammation markers related to obesity and on the expression of genes engaged on white adipose tissue lipid metabolism in a murine model of diet-induced obesity. The treatments improved energy expenditure, β-oxidation and adipogenesis by upregulating PPARα, PGC1α, PPARγ and UCP-1. Adipogenesis was also confirmed by image analysis of the retroperitoneal adipose tissue, by measuring cell area, perimeter and cellular density. Additionally, the treatments, ameliorated adipose tissue accumulation, insulin resistance, blood pressure, cholesterol and triglycerides concentration in serum, and reduced lipogenesis and inflammation by downregulating acetyl-CoA carboxylase (ACC) gene expression, increasing serum concentration and expression of adiponectin as well as downregulating IL-6 expression. Both fucoxanthin and Undaria pinnatifida may be considered for treating obesity and other diseases related.
