This study evaluated the anti-adipogenic effects and mechanisms underlying the action of Lactobacillus fermentum MG4231 and MG4244 strains on adipogenesis and lipid accumulation in 3T3-L1 preadipocytes. Treatment with cell-free extracts (CFEs) from the two strains reduced lipid accumulation and intracellular triglyceride production in 3T3-L1 adipocytes by more than 50%. The inhibitory effects of L. fermentum on lipid accumulation were mediated by the downregulation of FAS and aP2 resulting from the inhibition of PPARγ and C/EBPα gene expression. Moreover, AMPK and HSL phosphorylation was upregulated by CFE treatment. These results indicated that the anti-adipogenic and lipolysis activities of L. fermentum strains were caused by increased AMPK and HSL phosphorylation. Both strains displayed high leucine arylamidase and β-galactosidase enzymatic activity, with excellent adhesion to epithelial cells. Therefore, we identified L. fermentum as potential new probiotics for the prevention of obesity.Mistletoe offers health-promoting effects; however, it has toxicity, requiring careful application. Viscothionin is a polypeptide of mistletoe that while contributing to toxicity also demonstrates anti-cancer and anti-diabetic activities. The aim of this study was to evaluate whether gamma irradiation or heating treatment could selectively reduce viscothionin-mediated cytotoxicity. Gamma irradiation effectively inhibited viscothionin-induced cytotoxicity to RIN5mF cells, but heating treatment did not affect its cytotoxicity. Both heating and gamma irradiation further increased the insulinotropic activity of viscothionin, whereas the effect of gamma irradiation was dose-dependent and diminished above 20 kGy. Structural analysis showed that gamma irradiation significantly altered the ordered structure of viscothionin, unlike heating treatment, resulting in a change of its molecular properties, which could be linked to the observed changes in the cytotoxicity and insulinotropic activity of the polypeptide. These results suggest gamma irradiation as an alternative method for minimizing viscothionin toxicity without interfering with anti-diabetic effect.In this study, the anti-oxidative and neuro-protective effects of ethanolic extracts of the dried roots of Allium hookeri were investigated. Total phenolic contents and total flavonoid contents of A. hookeri extract depended on the ethanol concentrations used (50, 70 and 95%). In order to evaluate radical scavenging activity, DPPH and ABTS radical scavenging assays and ferric reducing powers were evaluated. The results showed the 95% ethanol extract of A. hookeri (95AH) had higher phenolic and flavonoid contents, and greater radical scavenging activities than 50 or 70% ethanol extracts of A. hookeri. The neuro-protective effects of 95AH were evaluated using H2O2-treated PC12 neuronal cells. Treatment of 95AH increased cell viability and superoxide dismutase and glutathione peroxidase activities, reduced lactate dehydrogenate release, reduced reactive oxygen species production, and increased Bcl-2/Bax ratio. HPLC revealed 95AH was rich in phenolics, especially catechin. These results demonstrate 95AH has substantial anti-oxidative and neuro-protective effects against H2O2-induced oxidative stress.The objective of this study is to investigate the effects of sea buckthorn oil (SBO) on proliferation, adipogenic differentiation and insulin sensitivity of 3T3-L1 cells. Results showed that SBO increased cell proliferation ability, accompanied by up-regulated proliferating cell nuclear antigen content (p  less then  0.05) and p38 activity (p  less then  0.05). SBO also promoted adipogenesis and enhanced adipogenic transcriptional factors expression. Mitochondrial biogenesis related gene expressions were elevated in SBO treated cells (p  less then  0.05). Of note, SBO also increased glucose uptake and glucose transporter 4 abundance (p  less then  0.05). Cells treated with SBO exhibited greater phosphorylated insulin receptor substrate 1 (p  less then  0.05), phosphorylated-Akt (p  less then  0.05) and phosphorylated AMP-activated protein kinase (p  less then  0.01) contents. When taken together, these results suggest that SBO promotes 3T3-L1 cells proliferation, adipogenesis and insulin sensitivity.Ferritins are iron-binding proteins that are basically participated in iron storage, detoxification, and immune response. In the present study, ferritin gene from the marine red algae Pyropia yezoensis was cloned into a pET21d expression vector. Selleck NST-628 High-efficiency transformation was performed in Escherichia coli BL21, the recombinant protein was expressed by induction with 0.1 mM isopropyl-β-D-thiogalactoside and purified via ammonium sulfate precipitation, anion exchange and size exclusion chromatography. The purified recombinant ferritin from P. yezoensis (rPyFer) was characterized and analyzed for its antimicrobial activity against both Gram-negative and Gram-positive bacterial cultures and exhibited significant antibacterial activity against Gram-positive cultures. The recombinant protein was also analyzed for its iron-uptake and radical-scavenging activities; rPyFer exhibited significant iron-uptake activity at low concentrations, and its radical-scavenging activity increased in a dose-dependent manner. This research will contribute to the development of new therapeutic proteins from marine algae.A new aminopeptidase (An-APa) was identified and biochemically characterized from Aspergillus niger CICIM F0215. It had maximal activity at 40 °C and pH 7.0 and exhibited a broad substrate specificity both on hydrophilic and hydrophobic amino acid residues at N-terminals. With An-APa hydrolysis for 1 h, the casein-pepsin and soybean protein isolates (SPI)-pepsin hydrolysates released both hydrophilic and hydrophobic amino acids and the hydrophobic amino acids having Q values (degree of hydrophobicity) greater than 1500 cal/mol were remarkably released. Leu, Ile, Phe, Tyr, Trp, Pro, Val and Lys in the casein hydrolysate after treatment with An-APa increased 18.61, 0.84, 11.35, 13.18, 3.34, 6.30, 7.46, and 8.19 mg/100 mL, respectively, and 19.72, 1.47, 18.37, 11.72, 4.61, 4.10, 8.13, and 5.85 mg/100 mL, respectively, in the SPI hydrolysate. Both accounted for 65.0% and 64.4% of total released free amino acids from casein and SPI hydrolysates, respectively. This indicated that An-APa could be potentially applicable in debittering protein hydrolysates.
