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:Obesity has considerable effects on morbidity and mortality, and the prevalence of obesity has been increasing rapidly worldwide during the past two decades. Even if obesity affects the entire individual, adipose tissue plays a central role in the development of obesity. Expression profiling of adipose tissue may give insights into the mechanisms contributing to obesity and obesity-related disorders. The Swedish Obese Subjects (SOS) Sib-Pair Study consists of 154 nuclear families with BMI-discordant sib pairs (BMI difference more than 10 kg/m2) resulting in a study population consisting of 732 subjects. The full SOS Sib-Pair study offspring cohort consists of 425 subjects. Microarray expression analysis in subcutaneous adipose tissue was performed in 375 subjects (262 women and 113 men) of the SOS Sib-Pair offspring cohort. Microarray expression analysis in subcutaneous adipose tissue was performed in women (n=262) and men (n=113) of the SOS Sib-Pair offspring cohort.

Project description:We performed single-nucleus RNA-seq using 10X on 84 randomly sampled participants from the METabolic Syndrome In Men (METSIM) cohort. The purpose of the study was to characterize cell type composition changes associated with metabolic diseases such as obesity and type 2 diabetes.

Project description:In this study, we examined the association of DNA methylation with metabolic traits in humans using adipose tissue samples from the Metabolic Syndrome in Men (METSIM) cohort. The METSIM cohort has been thoroughly characterized for longitudinal clinical data of metabolic traits including a 3-point oral glucose tolerance test, cardiovascular disorders, diabetes complications, drug and diet questionnaire, as well as high density genotyping, and genome-wide expression in adipose. We performed epigenome-wide association studies on clinical traits using reduced representation bisulfite sequencing data and identified 61 signifiant associations for metabolic syndrome traits, corresponding to 25 unique loci. These associations include previously known genes, FASN, RXRA, MSH2, and MSH6, as well as 22 loci harboring 18 new candidate genes for diabetes and obesity in humans.

Project description:The biological functions of epicardial adipose tissue (EAT) remain largely elusive. However, the proximity of EAT to the coronary arteries suggests a role in the pathogenesis of coronary artery disease (CAD). Objectives of this study were to identify genes that are up- or down-regulated among three adipose tissues (AT), namely EAT, mediastinal (MAT) and subcutaneous (SAT) and to study their possible relationships with the development of cardiovascular diseases. Samples were collected from patients undergoing coronary artery bypass grafting surgeries. Gene expression was evaluated in all three AT depots of six men using the lllumina® HumanWG-6 v3.0 expression BeadChips. Twenty-two and 73 genes were up-regulated in EAT compared to mediastinal and subcutaneous AT, respectively. Ninety-four genes were down-regulated in EAT compared to subcutaneous adipose depot. However, none were significantly down-regulated in EAT compared to mediastinal fat. More specifically, the expression of the adenosine A1 receptor (ADORA1), involved in myocardial ischemia, was significantly up-regulated in EAT. Levels of the prostaglandin D2 synthase (PTGDS) gene, recently associated with the progression of atherosclerosis, were significantly different in the three pairwise comparisons (epicardial > mediastinal > subcutaneous). The results of ADORA1 and PTGDS were confirmed by qPCR in 25 biological replicates. Overall, the transcriptional profiles of EAT and MAT were similar compared to the subcutaneous compartment. Despite this similarity, two genes involved in cardiovascular diseases, ADORA1 and PTGDS, were up-regulated in EAT. These results provide insights about the biology of EAT and its potential implication in CAD. Samples of epicardial, mediastinal and subscutaneous adipose tissue were collected from the chest of 6 male patients undergoing coronary artery bypass grafting surgeries. The RNA was labeled and hybridized using a standard Illumina protocol (https://icom.illumina.com/Login?ReturnUrl=%2ficom%2fsoftware.ilmn%3fid%3d214&id=214). Three pairwise comparison among the three adipose tissue were made using significance analysis of microarrays.

Project description:Objective: Insulin regulates amino acid metabolism. We investigated whether glycemia and 43 genetic risk variants for hyperglycemia/type 2 diabetes affect amino acid levels in a large population-based cohort. Subjects and Methods: A total of 9,371 non-diabetic or newly-diagnosed type 2 diabetic Finnish men from the population-based METSIM Study were studied. Proton NMR spectroscopy was used to measure plasma levels of 8 amino acids. Genotyping of 42 SNPs and mRNA microarray analysis from 200 subcutaneous adipose tissue samples were performed. Results: Increasing fasting and/or 2-hour plasma glucose levels were associated with increasing levels of alanine, valine, leucine, isoleucine, phenylalanine and tyrosine, and decreasing levels of histidine and glutamine. We also found significant correlations between insulin sensitivity (Matsuda ISI) and expression of genes regulating amino acid metabolism. Only one SNP (rs780094 in GCKR) of the 42 risk SNPs for type 2 diabetes or hyperglycemia was significantly associated with the levels of alanine, isoleucine, and glutamine. Conclusions : We observed that the levels of branched-chain, aromatic amino acids and alanine increased and the levels of glutamine and histidine decreased with increasing glycemia. These associations seemed to be mediated by insulin resistance, at least in part. GCKR rs780094 was significantly associated with several amino acids. Total RNA was obtained from subcutaneous fat biopsies from 200 people participating in the METSIM study (4 samples were replicated for a total of 204 arrays).

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:Individualized analysis through expression profiling of 20,000 probes in 28 tissue samples evaluated in subcutaneous and omental adipose tissue obtained during surgical intervention in non-obese and obese patients. Patients consisted of men and women of varying body size (lean to severely obese). Samples were collected at the time of operation in the fasting state. Samples consisted of subcutaneous and omental adipose tissue as well as a blood sample from lean and obese men and women removed in the fasting state at the time of surgery.
