(Submitter supplied) Cancer progression is mediated by processes that are also important in wound repair. As a result, cancers have been conceptualized as overhealing wounds or "wounds that do not heal," and gene expression signatures reflective of wound repair have shown value as predictors of breast cancer survival. Despite the widespread acknowledgment of commonalities between host responses to wounds and host responses to cancer, the gene expression responses of normal tissue adjacent to cancers have not been well characterized.

(Submitter supplied) Activation of inflammatory pathways is one plausible mechanism underlying the association between obesity and increased breast cancer risk. However, macrophage infiltration and local biomarkers of inflammation in breast adipose tissue have seldom been studied in association with obesity. Gene expression profiles of normal breast tissue from reduction mammoplasty patients were evaluated by whole genome microarrays to identify patterns associated with obesity status (normal-weight, body mass index (BMI) <25; overweight, BMI 25-29.9; obese, BMI > or equal to 30). more...

(Submitter supplied) Genome-wide expression profiles in peripheral monocytes (PM) from 19 obese women before and 3 months after bariatric surgery using the RNA-seq technology. This dataset is linked to the dataset GSE65540 providing expression profiles in subcutaneous adipose tissue (SAT) in the same population. Due to exclusion of some individuals for technical reasons, the overlap between the 2 datasets is of 18 women.

(Submitter supplied) Bariatric surgery is the most effective therapy of severe human obesity. It is associated with improvements in metabolic and non metabolic co-morbidities which are thought to be mediated by a decrease of adipose tissue inflammation. However, the molecular mechanisms behind these beneficial effects are poorly understood. We analyzed expression profiles in subcutaneous adipose tissue from 22 obese women before and 3 months after surgery using the RNA-seq technology. more...

(Submitter supplied) Obesity is a major risk factor for metabolic disorders like insulin resistance and diabetes. We previously identified GPS2 as a clinical relavant repressor of metaflammation. No animal KO models were used to study its physiological function in vivo. The role of GPS2 in macrophage activation and inflammation is also largely unknown. Here we developed a GPS2 myeloid specific KO mice to study the regulation of GPS2 in macrophage inflammation. more...

(Submitter supplied) GPS2 binding sites in BMDMs can be localized specially in enhancers (H3K27ac) and promoters (H3K27ac, H3K4me3). Upon GPS2 knock-out in BMDMs, de-repression of certain inflammatory genes occur, as accompanied by increased recruitment of H3K27ac and H3K4me3 marks.

(Submitter supplied) Obesity is a risk factor for numerous metabolic disorders; however, not all obese individuals are prone to insulin resistance. The central aim of this study was to identify molecular pathways directly related to insulin resistance independent of BMI in obesity. We sought to determine the gene expression signature of adipose tissue in a body mass index (BMI)-matched obese cohort of patients that are either insulin sensitive or insulin resistant.

(Submitter supplied) Background/Objectives: Obese subjects have increased number of enlarged fat cells which are reduced in size but not number in post-obesity. We performed DNA methylation profiling in fat cells with the aim of identifying differentially methylated DNA sites (DMS) linked to adipose hyperplasia (many small fat cells) in post-obesity. Subjects/Methods: Genome-wide DNA methylation was analyzed in abdominal subcutaneous fat cells from 16 women examined two years after gastric bypass surgery at a post-obese state (BMI 26±2 kg/m2, mean±s.d.) and 14 never-obese women (BMI 25±2 kg/m2). more...

(Submitter supplied) In human obesity, the stroma vascular fraction (SVF) of white adipose tissue (WAT) is enriched in macrophages. These cells may contribute to low-grade inflammation and to its metabolic complications. Little is known about the effect of weight loss on macrophages and genes involved in macrophage attraction. We examined subcutaneous WAT (scWAT) of 7 lean and 17 morbidly obese subjects before and 3 months after bypass surgery. more...

(Submitter supplied) The intention of this clinical study was to investigate the effect of GIP administration for 240 min on gene expression in human subcutaneous adipose tissue. Three conditions have been tersted: 1. Sole infusion of GIP or NaCl as control; 2. GIP or NaCl administration under euglycemic-hyperinsulinemic clamp conditions; 3. GIP or NaCl administration under hyperglycemic-hyperinsulinemic clamp conditions to mimic the postprandial state.

(Submitter supplied) Normal-appearing epithelium of cancer patients can harbor occult genetic abnormalities. Data comprehensively comparing gene expression between histologically normal breast epithelium of breast cancer patients and cancer-free controls are limited. The present study compares global gene expression between these groups. We performed microarrays using RNA from microdissected histologically normal terminal ductal-lobular units (TDLU) from 2 groups: (i) cancer normal (CN) (TDLUs adjacent to untreated ER1 breast cancers (n = 14)) and (ii) reduction mammoplasty (RM) (TDLUs of age-matched women without breast disease (n = 15)). more...
