Charaterization of the molecular impacts of one week high fructose diet in human skeletal muscle

ABSTRACT: The adaptive mechanisms in response to excess energy supply are still poorly known in humans. Our aims were to define metabolic responses and changes in gene expression in skeletal muscle of healthy offsprings of type 2 diabetic patients during one week of high fructose diet.

Peri-adolescent high-fructose diet effects on hypothalamic transcriptome

Project description:Fructose consumption has increased by over 25% since 1970, and excess consumption has deleterious metabolic effects. Additionally, fructose can alter hypothalamic pituitary adrenal axis function, potentially resulting in increased vulnerability to mood disorders. Adolescents are the greatest consumers of fructose and also at a critical period of development. Here, we examine the effects of consumption of a 55% fructose diet from weaning until adulthood on the hypothalamic transcriptome.

Charaterization of the initial molecular events of adipose tissue development and growth during overfeeding in humans

Project description:The adaptive mechanisms in response to excess energy supply are still poorly known in humans. Our aims were to define metabolic responses and changes in gene expression in adipose tissue of healthy volunteers during fat overfeeding. Healthy lean and overweight subjects were submitted to a high fat diet during 56 days. Adipose tissue biopsies were taken at Day 0, Day 14 and Day 56.

Polyphenols protection against fructose overload

Project description:To decipher the beneficial effects of Polyphenols on health, healthy volunteers were randomized into two groups and were submitted to either a red grape polyphenol rich extract supplemented diet (PP) or a placebo diet (PCB) during 8 weeks. Then they were submitted to a fructose load (3g/kg Fat Free Mass/day) during 7 days. Muscle biopsies were taken before the protocol, 8 weeks after PP or PCB diet and after the 7 days fructose load. We have employed whole genome microarray expression profiling as a discovery platform to identify genes regulated by fructose and to identify the mechanism of action of Polyphenols.

Ten biological replicates were processed for PP diet, nine for PCB diet.

A Pilot Study to Determine Fructose Uptake by Primary Human Colorectal Tumors

Project description:This proposed study is designed to investigate the specific uptake of fructose by human colorectal tumors. In this study, subjects with colorectal cancer undergoing surgery will receive an oral sugar solution containing fructose or xylose prior to surgery. The tumor will then be resected, and a portion of the tissue will be used to measure the abundance of fructose and xylose. The study hypothesis is that the tumors will take up fructose sugar but not xylose sugar. A comparison of the sugar uptake between the tumor and normal tissues from the adjacent intestinal epithelium and smooth muscle and the liver will be conducted. This proposal will confirm that human colorectal cancer tumors can directly absorb dietary sugars, which has never been demonstrated.

p53 regulates a miRNA-fructose transporter axis in brown adipose tissue under fasting

Project description:Active thermogenic adipocytes voraciously consume energy substrates like fatty acids and glucose to maintain body temperature upon cold exposure. Despite strong evidence for the involvement of brown adipose tissue (BAT) in controlling systemic energy homeostasis upon nutrient excess, it is unclear how the activity of brown adipocytes is regulated in times of nutrient scarcity. Therefore, this study aimed to scrutinize factors that modulate BAT activity to balance thermogenic and energetic needs upon simultaneous fasting and cold-exposure. For an unbiased view we performed transcriptomic and miRNA sequencing analysis of BAT from acutely fasted (24 hours) mice under mild cold exposure. Combining these data with in-depth bioinformatic analyses and in vitro experiments, we defined a previously undescribed axis of p53 and miR-92a-1-5p that is highly upregulated by fasting in thermogenic adipocytes. p53, a fasting-responsive transcription factor, was previously shown to control genes involved in the thermogenic program and miR-92a-1-5p was found to negatively correlate with human BAT activity. Here, we elucidated fructose transporter Slc2a5 as one direct downstream target of this axis and show that fructose can be taken up by and metabolized in brown adipocytes. In sum, this study delineates a fasting-induced pathway involving p53 and miR-92a-1-5p impinging on Slc2a5 and suggests a contribution of fructose as an energy substrate in thermogenic adipocytes.
