Mice were divided into six groups: normal diet control (NC, AIN-93G normal diet), 60% HFD control (HFD), HFD containing metformin at 250 mg/kg b.w. (Met, positive control), and HFD containing BGE at 5, 10, or 20 mg/kg b.w. for 15 weeks. BGE administration significantly prevented HFD-induced increases in weight gain, organ weight, and adipose tissue mass. Furthermore, it resulted in decreased adipogenesis and lipogenesis-related factors, including phosphorylated mitogen-activated protein kinase, peroxisome proliferator-activated receptor gamma, CCAAT/enhancer-binding proteins, sterol regulatory element-binding protein 1, phosphorylated cAMP response element-binding protein, glucose-6-phosphate dehydrogenase, fatty acid synthase, dephosphorylated ATP-citrate lyase, dephosphorylated acetyl-CoA carboxylase, and lipoprotein lipase, in white adipose tissues. Moreover, BGE administration enhanced lipolysis in white adipose tissue, as evidenced by elevated levels of adipose triglyceride lipase, phosphorylated hormone-sensitive lipase, and protein kinase A, along with reduced levels of perilipin and phosphodiesterase 3B. BGE induced thermogenesis in brown adipose tissues, as reflected by the increased expression of AMP-activated protein kinase, uncoupling protein 1, and carnitine palmitoyltransferase 1 and decreased levels of fatty acid-binding protein 4. In conclusion, this study provides comprehensive evidence supporting the antiobesity effects of BGE, elucidating the underlying molecular mechanisms involved in preventing weight gain, suppressing adipogenesis, promoting lipolysis, and stimulating thermogenesis. These findings suggest the potential therapeutic utility of BGE in combating obesity and associated metabolic disorders (KHGASP-2023-034).</p>","PeriodicalId":16440,"journal":{"name":"Journal of medicinal food","volume":" ","pages":"922-930"},"PeriodicalIF":1.7,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141633664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HepG2 cells and liver tissue isolated from db/db mice treated with betaine were used. The present study investigated whether betaine ameliorates hepatic steatosis by inhibiting FoxO6/peroxisome proliferator-activated receptor gamma (PPARγ) signaling in liver cells. Interestingly, betaine notably decreased lipid accumulation in tissues with FoxO6-induced mRNA expression of lipogenesis-related genes. Furthermore, betaine inhibited the FoxO6 interaction with PPARγ and cellular triglycerides in high-glucose- or FoxO6-overexpression-treated liver cells. In addition, we confirmed that betaine administration via oral gavage significantly ameliorated hepatic steatosis in db/db mice. We conclude that betaine ameliorates hepatic steatosis, at least in part, by inhibiting the interaction between FoxO6 and PPARγ, thereby suppressing lipogenic gene transcription.","PeriodicalId":16440,"journal":{"name":"Journal of medicinal food","volume":"30 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142222734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mice were divided into seven groups: control, db/db, metformin, and RGEP at 50, 100, 200, and 400 mg/kg. Administered orally for 9 weeks, RGEP effects on glucose regulation and insulin sensitivity were assessed through various metabolic parameters. In addition, mRNA expression levels of genes associated with hepatic gluconeogenesis and insulin sensitivity were examined. Fasting blood sugar showed a significant decrease in all RGEP concentration groups, but OGTT and insulin tolerance test showed a significant decrease at the RGEP concentration of 400 mg/kg, indicating enhanced glycemic control. Moreover, RGEP dose-dependently decreased serum glucose, HbA1c levels, and homeostatic model assessment of insulin resistance values, suggesting its effectiveness in reducing insulin resistance in db/db mice. Furthermore, RGEP downregulated mRNA expression of key components in the gluconeogenesis pathway (G6Pase, FOXO1, GLUT4, and PEPCK), insulin sensitivity (leptin, insulin1, PTP1B, GLP-1, and DPP-4), and mitochondria energy metabolism (PGC1) in either the liver or pancreas, while simultaneously upregulating GLP-1 expression.

A comprehensive understanding of the amino acid metabolism within R. chingii is instrumental in the formulation and innovation of functional foods derived from this species. Utilizing advanced techniques such as wide-ranging untargeted metabolomics, transcriptome analysis, interaction network mapping, heat map analysis, and quantitative real-time PCR, we conducted a comprehensive assessment of the quality attributes across four distinct developmental stages of R. chingii. Our meticulous analysis uncovered a rich tapestry of 76 distinct amino acids and their derivatives within the developmental stages of R. chingii. The spectrum of essential amino acids was not only broad but also displayed a high degree of variety. Notably, leucine, lysine, and phenylalanine stood out as the most abundant amino acids, underscoring their significant presence throughout the growth cycle of R. chingii. The proportion of essential amino acids relative to the total amino acid content in R. chingii exhibited a notable trajectory of change throughout its developmental stages. It began with 30.92% in the immature green phase, advanced to 31.04% during the transition from green to yellow, peaked at 33.62% in the yellow to red stage, and then moderated to 30.43% in the full red phase. This pattern suggests a strategic modulation of amino acid composition, aligning with the evolving nutritional requirements and metabolic shifts as the fruit matures. Concurrent analysis of interaction networks and heat maps, alongside comprehensive profiling of amino acid metabolism and transcriptomic examination, was conducted to elucidate the intricate dynamics of cellular processes. The results showed that seven differentially expressed genes (DEGs) played important roles in amino acid metabolism, including PFK, BCAT1, TSB, ASA, ACO, TOM2AH3, and BCAT2. The expression patterns of seven DEGs conformed closely to the findings revealed by the preceding RNA-seq analysis. In this investigation, we elucidated the regulatory mechanisms underlying amino acid metabolism across the four distinct developmental stages of R. chingii through comprehensive amino acid profiling and transcriptomic analysis.
