Project description:We analyzed the abdominal subcutaneous adipose tissue of 434 male human subjects from the METSIM study, via RNA-sequencing. The METSIM study was approved by the Ethics Committee of the University of Eastern Finland and Kuopio University Hospital in Kuopio, Finland and carried out in accordance with the Helsinki Declaration. Written informed consent was obtained from all participants. Here, we provide the expression values by gene for each subject and relevant covariates. Raw fastq files will be contributed to dbGaP, as they require controlled access.

Project description:Obtaining adipose tissue samples are paramount to the understanding of human obesity. We have examined the impact of needle-aspirated and surgical biopsy techniques on the study of subcutaneous adipose tissue (scAT) gene expression in both obese and lean subjects. Biopsy sampling methods have a significant impact on data interpretation and revealed that gene expression profiles derived from surgical tissue biopsies better capture the significant changes in molecular pathways associated with obesity. We hypothesize that this is because needle biopsies do not aspirate the fibrotic fraction of scAT; which subsequently results in an under-representation of the inflammatory and metabolic changes that coincide with obesity. This analysis revealed that the biopsy technique influences the gene expression underlying the biological themes commonly discussed in obesity (e.g. inflammation, extracellular matrix, metabolism, etc), and is therefore a caveat to consider when designing microarray experiments. These results have crucial implications for the clinical and physiopathological understanding of human obesity and therapeutic approaches. Keywords: subject and tissue biopsy technique comparison Tissue samples from lean and obese subjects were analyzed: total of 36 hybridizations. The goal was to compare the effect of biopsy sampling methods on global subcutaneous adipose tissue gene expression analyses. The following subject groups were used for the analysis: 9 lean subjects: needle biopsy 9 lean subjects: surgical biopsy 9 obese subjects: needle biopsy 9 obese subjects: surgical biopsy

Project description:We analyzed samples from 770 male human subjects who are part of the METSIM study. Ethics Committee of the Northern Savo Hospital District approved the study. All participants gave written informed consent. The population-based cross-sectional METSIM study included 10 197 men, aged from 45 to 73 years, who were randomly selected from the population register of the Kuopio town in eastern Finland (population 95000). Every participant had a 1-day outpatient visit to the Clinical Research Unit at the University of Kuopio, including an interview on the history of previous diseases and current drug treatment and an evaluation of glucose tolerance and cardiovascular risk factors. After 12 h of fasting, a 2 h oral 75 g glucose tolerance test was performed and the blood samples were drawn at 0, 30 and 120 min. Plasma glucose was measured by enzymatic hexokinase photometric assay (Konelab Systems reagents; Thermo Fischer Scientific, Vantaa, Finland). Insulin was determined by immunoassay (ADVIA Centaur Insulin IRI no. 02230141; Siemens Medical Solutions Diagnostics, Tarrytown, NY, USA). Height and weight were measured to the nearest 0.5 cm and 0.1 kg, respectively. Waist circumference (at the midpoint between the lateral iliac crest and lowest rib) and hip circumference (at the level of the trochanter major) were measured to the nearest 0.5 cm. Body composition was determined by bioelectrical impedance (RJL Systems) in subjects in the supine position.

Project description:Gene expression profiles of biopsy samples of subcutaneous adipose of three female patients of type 2 diabetes and three non-diabetic female patients were generated using Illumina HumanHT-12 v3 Expression BeadChip arrays. The primary indications of surgery were non-infective and non-malignant conditions, namely, cholelethiasis, hernia and trauma.
