3M-Brazzein, a Natural Sugar Substitute, can Suppress Metabolic Disorders, NAFLD, and Depression-like Behaviors in Diabetic Mice

ABSTRACT: The increasing consumption of sugar-sweetened beverages (SSBs) in modern society has enhanced the epidemic of obesity, metabolic disorders, and mental illnesses. Therefore, the current study investigated the potential of 3M-Brazzein as a promising natural sugar substitute. 4-weeks-old leptin receptor knockout mice (db/db) were supplied with water, 10% sucrose solution, or a 3M-Brazzein solution respectively for 16 weeks. Chronic consumption of 3M-Brazzein did not cause any degeneration of adipogenesis, insulin resistance, hepatic lipogenesis, and depression-like behaviors. However, 10% sucrose consumed mice exhibited completely different outcomes. Furthermore, the mRNA expression levels of GLUT2, SREBF-1, and PPARγ in liver were significantly increased in knockout mice supplied with the 10% sucrose solution, thereby the excessive sucrose consumption induced severe obesity, impairment of glucose homeostasis, non-alcoholic fatty liver disease (NAFLD), and major depressive disorder in them. Consequently, the present study demonstrated the positive effects of 3M-Brazzein on various health problems prevalent in the modern world, and suggests some genetic clues related to the pathogenesis of NAFLD and major depressive disorder.

High intake of dietary sucrose induces sexually dimorphic metabolic adaptations in liver and adipose tissue

Project description:This data submission reports the effects of 12 weeks supplementaion of 10%w/v sucrose supplied in drinking water on the inguinal white adipose tissue mRNA profiles of male and female mice relative to control groups (littermates that received plain water instead). RNAseq was performed by Novogene and investigators performed all analyses downstream of readcount acquisition. Manuscript abstract: Almost all effective treatments for non-alcoholic fatty liver disease (NAFLD) involve reduction of adiposity, which suggests the metabolic axis between liver and adipose tissue is essential to NAFLD development. Since excessive dietary sugar intake may be an initiating factor for NAFLD, we have characterized the metabolic effects of liquid sucrose intake at concentrations relevant to typical human consumption in mice. We report that sucrose intake induces sexually dimorphic effects in liver, adipose tissue, and the microbiome; differences concordant with steatosis severity. We show that when steatosis is decoupled from impairments in insulin responsiveness, sex is a moderating factor that influences sucrose-driven lipid storage and the contribution of de novo fatty acid synthesis to the overall hepatic triglyceride pool. Our findings provide physiologic insight into how sex influences the regulation of adipose-liver crosstalk and highlight the importance of extrahepatic metabolism in the pathogenesis of diet-induced steatosis and NAFLD.

Differential transcriptional networks regulated by high sugar consumption in normal and high-fat-fed mice

Project description:High sugar consumption, as well as high-fat diet, is a known cause of obesity and metabolic syndrome. However, the synergistic effect of high-sugar and high-fat consumption rarely has been evaluated, especially in terms of transcriptional regulation. Therefore, we focused on the effect of high sugar consumption on hepatic transcriptional networks in normal and high fat-fed mice. C57BL/6J mice were divided into four groups and were provided either 23%(w/v) sugar solution or plain water with either high-fat or normal-fat diet for 10 weeks. As a result, high sugar consumption significantly altered lipid metabolism-related genes in normal fat-fed mice; however, in high fat-fed mice, high sugar consumption altered inflammation-responsive genes rather than lipid metabolism. After all, these modulations eventually increased lipid accumulation in the liver and caused systemic metabolic disturbances. These observations for the first time suggested that high sugar consumption along with high-fat diet could lead to the development of severe metabolic syndrome via altering hepatic transcriptional networks.

Influence of dietary sucrose and copper content in a rat model of non-alcoholic fatty-liver disease

Project description:Nutrigenomics analysis was used to investigate the molecular responses to dietary Cu deficiency independently and in combination with 30% (w/w) sucrose in a mature rat model of NAFLD. Low Cu significantly decreased hepatic and serum Cu, and induced NAFLD-like histopathology, mild steatosis, up-regulated transcripts in inflammation and hepatic stellate cell activation, and significantly increased oxidative stress. Rats fed low Cu together with 30% sucrose also developed insulin resistance, increased ATP citrate lyase and FASN expression, and greater oxidative stress. High sucrose with adequate Cu also promoted inflammation and fibrosis, but not steatosis. This study indicates that low dietary Cu and sucrose consumption are singular and synergistic dietary factors in promotion of NAFLD and NASH that act independently of obesity or severe steatosis, likely by promoting oxidative stress and activation of inflammation and fibrosis. Mature (6 months old) male Wistar Rats that had been allowed ad libitum access to Mazuri rodent pellets were used in the study. Twenty-four rats were divided into four groups and fed for 12 weeks with diets based on the Purified AIN76A formulation, modified for target sucrose and Cu content (Custom Animal Diets, Bangor, NJ). Sucrose and copper content in diets were as follows: ‘A’ CuD/30%- Cu deficient (<0.3 mg Cu/kg)/30% sucrose, ‘B’ CuA/30%- Cu adequate (125 mg/kg)/30% sucrose, ‘C’ CuD/10%- <0.3 mg/kg Cu/10% sucrose, and ‘D’ CuA (125 mg/kg Cu)/10% sucrose (control). Starch and dextrin were used to equalize carbohydrates.

Hepatic gene expression profiles of db/db mice with non-alcoholic fatty liver

Project description:Nonalcoholic fatty liver disease (NAFLD) is a common disorder in obese people and is becoming the leading cause of hepatocellular carcinoma (HCC). Recently, lncRNAs have been proven to play remarkable roles in numerous biological processes and human diseases, including NAFLD. However, the function of lncRNA in NAFLD pathogenesis remains largely unknown. The aim of this study was to explore the lncRNA expression profile in NAFLD mice and to identify novel lncRNAs involved in the pathogenesis of NAFLD. We performed microarray analysis to compare the expression profiles of lncRNAs and mRNAs in the liver of diabetic db/db mice with NAFLD and normal mice.

Control of sucrose accumulation in sugarcane (Saccharum spp. hybrids) involves miRNA-mediated regulation of genes and transcription factors associated with sugar metabolism

Project description:Sugarcane established industrial crop providing sugar, ethanol and biomass-derived electricity around the world. Cane sugar content is an important, breeding target, but its improvement remains very slow in many breeding programmes. Biotechnology strategies to improve sucrose accumulation made little progress at crop level, mainly due to the limited understanding of its regulation. MiRNAs regulate many metabolic processes in plants. However, their roles and target genes associated with sugarcane sucrose accumulation remains unknown. Here, we conducted high-throughput sequencing of transcriptome, small RNAs and degradome of leaves and stem of two sugarcane genotypes with contrasting sucrose content from the early to late stages of sucrose accumulation stages, which provided more insights into miRNA-associated gene regulation during sucrose accumulation. Transcriptome analysis identified 18,722 differentially expressed genes (DEGs) between both genotypes during sucrose accumulation. The major DEGs identified were involved in starch and sucrose metabolism, and photosynthesis etc. miRNA sequencing identified 563 known and 281 novel miRNAs from both genotypes during sucrose accumulation. Of these, 311 miRNAs were differentially expressed.752 targets of 368 miRNAs (609 targets for 260 known miRNAs and 168 targets for 108 novel miRNAs) were identified by degradom sequencing.Several known and novel miRNAs and their target genes associated with sugar metabolism, sugar transport and sucrose storage were identified in this study.This new insight into the complex network of sucrose accumulation in sugarcane will help identify candidate targets for sucrose improvement in sugarcane through molecular means.
