Transcriptomic profiling of murine adipose endothelial cells from high-fat diet fed mice

ABSTRACT: Female mice display greater adipose angiogenesis and maintain healthier adipose tissue than do males upon sustained high-fat diet feeding. We utilized transcriptome analysis of endothelial cells (EC) from the white adipose tissue of male and female mice that were fed a high-fat for 7 weeks. We found that adipose EC exhibited pronouncedly sex-distinct transcriptomes. Genes upregulated in female adipose EC were associated with proliferation, oxidative phosphorylation, and chromatin remodeling contrasting the dominant enrichment for genes related to inflammation and a senescence-associated secretory of male EC. Our study provides novel insights into molecular programs that distinguish male and female EC responses to pathophysiological conditions.

Male and female flow sorted adipose tissue macrophages and hematopoietic stem cells

Project description:Comparison of hematopoetic stem cells (HSC) and adipose tissue macrophages (ATM) in mouse adipose tissue. HSCs are progenitors for circulating leukocytes and recruited tissue macrophages. Males have increased numbers of ATMs and HSCs in response to high fat diet. In addition there are qualitative differencs with male ATMs releasing pro-inflamatory cytokines and factors impairing adipocyte function. M: male, F: female, ND: normal diet, HF: high fat diet.

Proteomics analysis of white adipose tissue in high fat diet fed mice

Project description:The popularity of high fat foods in modern society has been associated with epidemic of various metabolic diseases characterized by insulin resistance, the pathology of which involves complex interactions between multiple tissues such as liver, skeletal muscle and white adipose tissue (WAT). To uncover the mechanism by which excessive fat impairs insulin sensitivity, we conducted a multi- tissue study by using TMT-based quantitative proteomics. 3-week-old ICR mice were fed with high fat diet (HFD) for 19 weeks to induce insulin resistance. Liver, skeletal muscle and epididymal fat were collected for proteomics screening. Additionally, PRM was used for validating adipose differential proteins. By comparing tissue-specific protein profiles of HFD mice, multi-tissue regulation of glucose and lipid homeostasis and corresponding underlying mechanisms was systematically investigated and characterized.

Project description:The purpose of this study was to investigate whether paternal high-fat diet (HFD) transgenerationally remodels the epigenome of spermatozoa to alter metabolism in the F1 and F2 generation offspring White adipose tissue mRNA expression profiling of F2-female offspring from F0-founders fed either a chow or a chronic HFD challenged. Adult females were challenged or not a high-fat diet for 12 weeks. White adipose tissue was dissected at an endpoint experiment. Rats were subjected to 4 hours fasting prior to anesthesia with pentobarbital and tissue collection.

Effects of PCB 52 Exposure Via Sub-Acute Nose-Only Inhalation on Gene Expression in Fat Depots of Adolescent Rats

Project description:Polychlorinated biphenyls (PCBs) are persistent environmental toxicants that pose a variety of health risks in humans. PCB 52 has been found in the indoor air of schools where adolescent students and staff are being actively exposed. This study examined the three different fat depots, namely, brown adipose tissue (BAT), subcutaneous adipose tissue (SAT), and visceral adipose tissue (VAT), of adolescent Sprague-Dawley rats after sub-acute exposure to PCB 52 via nose-only inhalation. Rats were exposed for 4 hours daily for 28 consecutive days. RNA extracted from both male and female fat depots were submitted for RNA sequencing to compare the effects of PCB 52 on the expression of genes in the fat depots.

MicroRNAs Expressed in Visceral Adipose Tissue from Mice Fed High-Fat Diets Supplemented with Eicosapentaenoic Acid (EPA)

Project description:The goal of this subproject is to identify microRNAs (miRNAs) expressed in visceral (VIS) adipose tissue (gonadal fat from male C57BL/6 mice) and regulated by eicosapentaenoic acid (EPA). This will provide insight into microRNAs regulated by EPA and their potential role in obesity-associated inflammation. We performed small RNA-sequencing of white (VIS) adipose tissue from high-fat diet (45% kcal from fat) supplemented with EPA (45% Kcal from fat, 6.75% EPA). Using the Gunaratne Next-Generation pipeline (published in Creighton et al. 2009), miRNA expression profiles were identified. Counts of each unique read were normalized to total usable reads, and had 40 counts added. We mapped about 13.8 million sequence reads per sample to the Mus musculus genome (build mm 10). We are specifically interested in those miRNAs expressed in VIS fat from EPA-fed mice compared to HF-fed mice.

Response of the adipose tissue transcriptome to dihydrotestosterone in mice

Project description:Androgens have been postulated to be important modulators of adipose tissue metabolism and fat cell function. In the present study, we investigated the response of male and female mice retroperitoneal adipose tissue to the non-aromatizable androgen dihydrotestosterone (DHT). Adipose tissue samples were obtained in gonadectomized (GDX) animals treated with vehicle (control group), or injected with 0.1mg DHT at 1, 3, 6, 12, 18 and 24h prior to necropsy. Transcripts which were significantly modulated were considered as androgen-responsive genes. Quantitative real-time RT-PCR was used to confirm results from the microarry analysis in a subset of 46 probe sets in male mice and 98 probe sets in female mice. Using both methods and considering peak time versus control, 74.5% and 61.2% of the modulated genes were confirmed by PCR in males and females, respectively. Four genes were significantly stimulated in a similar manner by DHT in both sexes, namely metallothionein 1 (Mt1), growth arrest and DNA-damage-inducible 45 gamma (Gadd45g), cyclin-dependent kinase inhibitor 1A (Cdkn1a), and fk506-binding protein 5 (Fkbp5). All these genes appear to be associated with a down-regulation of adipocyte differentiation/proliferation and adipogenesis. In conclusion, this study which evaluated the transcriptome response of adipose tissue to DHT in male and female mice suggests that DHT consistently modulates genes involved in the regulation of adipogenesis in retroperitoneal adipose tissue of both male and female animals.

Expression data from germ-free and conventional mice fed lard or fish oil for 11 weeks

Project description:Dietary lipids and gut microbiota may both influence adipose tissue physiology. By feeding conventional and germ-free mice high fat diets with different lipid compositon we aimed to investigate how dietary lipids and the gut microbiota interact to influence inflammation and metabolism in epididymal adipiose tissue (EWAT) Wild-type C57Bl/6 male mice 11 weeks of age were fed isocaloric diets (45% kcal fat) with either menhaden fish oil (Research Diets, D05122102) or lard (Research Diets, D10011202) for 11 weeks. Epididymal WAT samples were harvested at the end of the experiment and analyzed by microarray.

scRNA of preadipocytes and mature adipocytes from mice exposed to a mouse model of early life stress

Project description:Background: Adipose tissue homeostasis is a complex process influenced by many mechanisms that become dysregulated with obesity. We have previously shown that Maternal Separation and Early Weaning (MSEW), a mouse model of early life stress, exacerbates high-fat diet (HF)-induced fat deposition in female mice, but not male mice. In addition, we have shown that this exacerbated adiposity is due to an increase in visceral adipose tissue, and fat depot known to be linked with cardio-metabolic dysfunction. Purpose: The aim of this study was to determine differential gene expression patterns in gonadal white adipose tissue (gWAT), a visceral fat, in female mice exposed to MSEW compared to controls. Adipose tissue is composed of many different stromal cell types including preadipocytes, mature adipocytes, and immune cells. Preadipocytes are the precursor stem cells that differentiate into mature adipocytes that can uptake and store lipids and have a more predominte endocrine function. Methods: Control and MSEW mice were weaned onto either a low-fat diet (LF) or a high-fat diet (HF) for 20 weeks. Fresh gonadal white adipose tissue was harvested after euthanasia and subjected to collagenase digestion. Tissue was centrifuged and filtered to separate the mature fraction from the stromal vascular fraction. Magnetic Activated Cell Sorting (MACs) was used to further isolate adipocytes from other cell types. Pre-and mature adipocytes were collected and saved in Purezol at -80oC for later RNA extraction using the Promega ReliaPrep RNA miniprep systems. Total RNA was sent to Novogene for scRNAseq analysis.
