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

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 adipose tissue of healthy volunteers during fat overfeeding.

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.

Adipose tissue of overfed animals during and after overfeeding

Project description:We report the transcriptomes (polyadenylated mRNAs over 200bp) of animals overfed through intragastric tubes either in the overfed state (OIO) or 24 hours after cessation of overfeeding (OIOneg). We also report transcriptomes of weight-matched mice either fed (ALO, or fasted 24 hours (ALOneg).

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

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 skeletal muscle of healthy offsprings of type 2 diabetic patients during one week of high fructose diet.

Epigenetic analysis of healthy young men following a control and high-fat overfeeding diet

Project description:Genome-wide DNA methylation profiling of healthy young men following a control and high-fat overfeeding diet using Illumina's Infinium 27k Human DNA methylation Beadchip v. 1.2. DNA methylation profiles were obtained for 27,578 CpG sites in human skeletal muscle. Randomized cross-over desgin, where all subjects receieved both treatments (control and high-fat overfeeding diet). Biopsies were obtained from 23 different individuals amounting to 22 samples following the control diet and 22 samples following the high-fat overfeeding diet (paired n=21). Bisulphite converted DNA from the 44 samples were hybridised to the Illumina Infinium 27k Human Methylation Beadchip.

Protection against overfeeding-induced weight gain in mice is preserved in obesity but does not require FGF21 or MC4R

Project description:Experimental overfeeding triggers homeostatic compensatory mechanisms that counteract weight gain. Here, we utilized intragastric overfeeding in mice to investigate the physiological and molecular responses to forced weight gain. Both lean and diet-induced obese (DIO) mice exhibited a potent and prolonged lowering of voluntary food intake following overfeeding-induced weight gain. Although overfeeding resulted in a marked increase in circulating fibroblast growth factor 21 (FGF21), experiments with FGF21 knockout (KO) mice demonstrated that FGF21 is dispensable for the homeostatic defense against experimental weight gain. Targeted proteomics unveiled novel circulating factors linked to overfeeding, including the protease legumain (LGMN). Notably, administration of recombinant LGMN lowered body weight and food intake in DIO mice. The protection against weight gain was also associated with reduced vascularization in the hypothalamus and sustained reductions in transcript levels of the orexigenic neuropeptides, Npy and AgRP, suggesting a role of hypothalamic signaling in the homeostatic recovery from overfeeding. Overfeeding of melanocortin 4 receptor (MC4R) KO mice showed that these mice can suppress voluntary food intake and counteract the enforced weight gain, although their rate of weight recovery is impaired. Collectively, these findings demonstrate that the defense against overfeeding-induced weight gain remains intact in obesity and involves mechanisms independent of both FGF21 and MC4R.

Epigenetic analysis of men with low birth weight following a control and high-fat overfeeding diet

Project description:Genome-wide DNA methylation profiling of young men born with low birth weight following a control and high-fat overfeeding diet using Illumina's Infinium 27k Human DNA methylation Beadchip v. 1.2. DNA methylation profiles were obtained for 27,578 CpG sites in human skeletal muscle. Randomized cross-over desgin, where all subjects receieved both treatments (control and high-fat overfeeding diet). Biopsies were obtained from 17 different individuals amounting to 16 samples following the control diet and 15 samples following the high-fat overfeeding diet (paired n=14). Bisulphite converted DNA from the 31 samples were hybridised to the Illumina Infinium 27k Human Methylation Beadchip.
