Abstract

OBJECTIVE: To optimize extracting parameters of flavonoids from Humulus lupulus. METHOD: Based on the single factors test on ethanol concentration, material and solvent ratio, extracting temperature and extracting time, orthogonal test was performed and the best combination was confirmed. RESULT: With the optimized technology, the maximal extracting amount of flavonoids from H. lupulus was 78 mg x g(-1). CONCLUSION: The optimal techniques obtained are 45% ethanol extracting at 60 degrees C with material and solvent ratio 1:25 for 90 min.

Role of Sanqi Baiji San in Mitigating Ethanol-Induced Gastric Epithelial Cell Injury via PI3K/AKT-related Signaling.

This work aimed to clarify the protective mechanism of Sanqi Baiji San (SQBJ) against ethanol-induced gastric epithelial cell injury and to explore its potential relevance to gastric ulcer (GU). Network pharmacology was used to screen SQBJ's active components (Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform [TCMSP], Oral Bioavailability [OB] ≥ 20%, Drug-Likeness [DL] ≥ 0.1), map their targets (Universal Protein Resource [UniProt]), collect GU-related targets (GeneCards/OMIM/DrugBank), and analyze overlapping targets via Gene Ontology (GO)/Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment and molecular docking. Ethanol-injured Gastric Epithelial Cell Line-1 (GES-1) cells were treated with SQBJ or the PI3K inhibitor LY294002. CCK-8 was used to determine the optimal SQBJ concentration. Network pharmacology analyses identified 126 common targets enriched within PI3K/AKT/MAPK-related cascades and suggested potential interactions between principal SQBJ constituents and PI3K/AKT-related proteins. In ethanol-challenged cells, SQBJ alleviated cell injury by reducing inflammatory mediator release and oxidative stress, as evidenced by decreased intracellular reactive oxygen species and malondialdehyde levels. SQBJ restored mitochondrial membrane potential and ATP content and reduced apoptosis-associated changes in B-cell lymphoma-2, cleaved caspase-3, and Bcl-2-associated X protein levels. SQBJ also modulated PI3K/AKT- and MAPK-associated signaling markers. These protective effects were largely weakened by LY294002, suggesting that PI3K/AKT-related signaling is involved in SQBJ-mediated cytoprotection. These findings provide an in vitro mechanistic basis for the potential application of SQBJ in GU, although further validation in animal models of ethanol-induced gastric ulcer is required.

Transcriptomic shift in ethanol and amino acid metabolic genes regulated by Med15 during alcoholic fermentation.

Organisms that thrive in extreme environments provide natural experiments in evolution, revealing the genetic regulators that orchestrate complex phenotypic change. Wine yeast (WY) are specialized strains that are adapted to survive in the wine making environment while producing high concentrations of ethanol. In addition to large genomic changes that differentiate WY from yeast used in other industries, SNP and polyglutamine tract polymorphism in the transcriptional regulator Med15 are associated with the fermentation efficiency and stress response phenotypes of WY. In this study, we investigated the transcriptional differences during wine fermentation in transgenic lab strain yeast having integrated WY MED15 alleles. Compared to the unmodified lab strain (MED15 LAB), the same strain in which the MED15 locus was replaced with a MED15 allele from yeast isolated from palm wine, the fermented sap of palm (oil, date, coconut) trees (MED15 WY23), exhibited enhanced expression of amino acid biosynthesis genes as well as stress resistance and metabolic adaptation genes. Our experimental data confirm the role of arginine in efficient fermentation and suggest that certain MED15 alleles alter the expression patterns of arginine pathway genes in some cases improving carbon flux under nitrogen stress. The global benefits conferred by natural polymorphisms in a single transcriptional regulator highlight Med15 as a target for engineering of strains devoted to various types of alcohol production.

Adaptive laboratory evolution of Saccharomyces cerevisiae CEN.PK 113-7D to enhance ethanol tolerance.

Saccharomyces cerevisiae is a widely used yeast for industrial production of ethanol. However, elevated ethanol, temperature, and osmotic stress adversely affect fermentation efficiency. In this study, adaptive laboratory evolution for S. cerevisiae CEN.PK 113-7D on higher concentrations of ethanol was performed. After 144 days, the maximum specific growth rate (&#xb5;max) increased from 0.0240 to 0.1150 h-1 for the strain evolved on 9% v/v ethanol, and from 0.0002 to 0.0530 h-1 for the strain evolved on 11% v/v ethanol, and the specific glucose uptake rate increased by 30%. The strain evolved on 11% ethanol produced 94.5&#xa0;g/L ethanol in a fermentation as compared to 78.5&#xa0;g/L production by a non-evolved strain. By whole-genome sequencing of the evolved clones, we identified multiple coding mutations in genes involved in processes such as stress response, cell growth regulation, pentose phosphate pathway, lipid synthesis, and redox balance. The selected mutations in RKI1, CYC2, ANR2, RGA2, RGA1, LPX1, and LRE1 genes were validated by introducing them in the nonevolved yeast, showing 1.7-5-fold growth improvement at 9% ethanol (P&#xa0;<&#xa0;0.05). Notably, RGA2, RGA1 and LPX 1 carried an identical missense mutation across three independent clones. The RKI1I208V mutant showed the highest ethanol tolerance, while CYC2N342A achieved the highest ethanol production.
