Transcriptomic signatures and chromatin structure in adipocytes isolated from premenauposal women subcutaneous fat [ATAC-seq]

ABSTRACT: Our data showed that lipid and glucose metabolic pathways genes were expressed at higher levels in gluteofemoral adipocyte fraction in pears, while genes associated with inflammation were higher in both abdominal and gluteofemoral apple adipocyte fraction. Gluteofemoral adipocyte chromatin from pear-shaped women contained a significantly higher number of differentially open ATAC-seq peaks relative to chromatin from the apple-shaped gluteofemoral adipocytes. In contrast, abdominal adipocyte chromatin openness showed few differences between apple and pear-shaped women. We revealed a correlation between gene transcription and open chromatin at the proximity of the TSS of some of the differentially expressed genes.

Human subcutaneous preadipocytes RNAseq

Project description:we performed RNA-seq and pathways analysis on human preadipocytes isolated from abdominal (A) and gluteofemoral (GF) fat of 10 apple-shaped women and 7 pear-shaped women . Out of the 23,511 annotated transcripts, 636 and 752 genes were differentially expressed in apple- compared to pear-shaped cells in A-FAT and GF-FAT respectively. Interestingly, one of the most significantly over-represented pathways from the apple-specific gene list was “Nucleotide Excision Repair pathway”.

Identification of metabolically distinct adipocyte progenitor cells in human adipose tissues

Project description:Adipocyte progenitor cells (APCs) provide the reservoir of regenerative cells to produce new adipocytes, although their identity in humans remains elusive. Using FACS analysis, gene expression profiling and metabolic and proteomic analyses, we identified three APCs subtypes in human white adipose tissues. The APC subtypes are molecularly distinct but possess similar proliferative and adipogenic capacities. Adipocytes derived from APCs with high CD34 expression exhibit exceedingly high rates of lipid flux compared with APCs with low or no CD34 expression, while adipocytes produced from CD34- APCs display beige-like adipocyte properties and a unique endocrine profile. APCs were more abundant in gluteofemoral compared with abdominal subcutaneous and omental adipose tissues, and the distribution of APC subtypes varies between depots and in patients with type 2 diabetes. These findings provide a mechanistic explanation for the heterogeneity of human white adipose tissue and a potential basis for dysregulated adipocyte function in type 2 diabetes.

Expression data from subcutaneous adipose tissue of lean polycystic ovary syndrome (PCOS) and normoandrogenic women

Project description:Lean polycystic ovary syndrome (PCOS) women have a greater proportion of android (abdominal) fat, increased numbers of small subcutaneous (SC) abdominal adipocytes and preferential intra-abdominal fat accumulation. This study examines whether abnormal gene expression of SC abdominal adipose stem cells (ASCs) from lean PCOS women underlies this altered abdominal adipose structure-function. In this dataset, we include the expression data obtained from PCOS and NL subcutaneous adipose tissue. Differential expression of at least 1.5-fold change (P<0.05) were obtained in 120 genes (48 upregulated, 72 downregulated) of SC abdominal ASCs from PCOS versus NL women

HOTAIR interacts with PRC2 complex regulating the regional preadipocyte transcriptome and human fat distribution

Project description:Mechanisms governing regional human adipose tissue (AT) development remain undefined. Here, we show that the long non-coding RNA, HOTAIR (HOX transcript antisense RNA), is exclusively expressed in gluteofemoral AT, where it is essential for adipocyte development. We find that HOTAIR interacts with Polycomb Repressive Complex 2 (PRC2) and identify core HOTAIR-PRC2 target genes involved in adipocyte lineage determination. Repression of target genes coincides with PRC2 promoter occupancy and H3K27 tri-methylation. HOTAIR is also involved in modifying the gluteal adipocyte transcriptome through alternative splicing. Gluteal-specific expression of HOTAIR is maintained by defined regions of open chromatin across the HOTAIR promoter. HOTAIR expression levels can be modified by hormonal (oestrogen, glucocorticoids) and genetic variation (rs1443512 is a HOTAIR eQTL associated with reduced gynoid fat mass in 25,200 individuals). These data identify HOTAIR as a dynamic regulator of the gluteal adipocyte transcriptome and epigenome with functional importance for human regional AT development.

Novel apple miRNAs and their possible involvement in Fire Blight defense

Project description:Fire blight (FB) is a bacterial disease affecting plants from Rosaceae family, including apple and pear. FB develops after the infection of Erwinia amylovora, gram-negative enterobacterium, and results in burnt-like damages and wilting, which can affect all organs of the plant. Although the mechanisms underlying disease response in apples are not elucidated yet, it has been well described that FB resistance depends on the rootstock type. The main objective of this work was to identify miRNAs involved in response to bacterial infection in order to better explain apple defense mechanisms against fire blight disease. We performed deep sequencing of eighteen small RNA libraries obtained from inoculated and non-inoculated Gala apple leaves. 233 novel plant mature miRNAs were identified together with their targets and potential role in response to bacterial infection. We identify three apple miRNAs responding to inoculation (mdm-miR168a,b, mdm-miR194C and mdm-miR1392C) as well as miRNAs reacting to bacterial infection in a rootstock-specific manner (miR395 family). Our results provide insights into the mechanisms of fire blight resistance in apple.

RNA-seq of in vitro differentiated human abdominal and gluteal adipocyte cell lines following doxycycline induced RSPO3-knockdown

Project description:GWAS studies and our own work have identified RSPO3 as a gene modulating human body fat distribution. The GWAS signal at RSPO3 is coincident with an eQTL in mature adipocytes. To assess the effects of RSPO3 on abdominal and gluteal adipocyte biology, we undertook inducible RSPO3-knockdown in in vitro differentiated immortalized human abdominal and gluteal adipocyte cell lines (DFAT cells).

Endothelial DLL4 is an adipose depot specific fasting sensor regulating fatty acid fluxes

Project description:Adaptation of adipose depots to change in fuel availability is critical for metabolic flexibility and cardio-metabolic health. The mechanisms responsible for fat depot-specific lipid sensing and shuttling remain elusive. We investigated the contribution of microvascular endothelial cells in this process. We performed transcriptional analysis of native microvascular endothelial cells isolated from paired biopsies of human gluteofemoral (GF-AT) and abdominal (Abdo-AT) subcutaneous adipose tissues. Gene expression profiles were performed using Agilent Sureprint G3 Human GE v3 microarrays.

Changes in CIDEA expression associate with adipocytes size and functionality in adolescent obese girls

Project description:About 20% of youth are obese with higher risk for cardiovascular disease and type 2 diabetes (T2D). We have recently reported that in obese adolescents altered pattern of fat distribution is associated with insulin resistance and T2D. In particular, the high ratio of visceral AT depot (VAT) to abdominal subcutaneous AT depot (SAT) (high VAT/(VAT+SAT)) was associated with a metabolically unhealthy phenotype with high risk for insulin resistance and T2D. CIDEA (Cell death inducing DNA fragmentation factor-alpha-like A) is a member of CIDE family and it is not only involved in the promotion of cell death and DNA fragmentation but it also plays critical roles in the lipid droplets formation and growth. Here we demonstrated in abdominal SAT from adolescent obese girls with high VAT/(VAT+SAT) a significant reduction of CIDEA expression associated with an increase in fasting insulin, serum FFA and consequent insulin resistance. We also demonstrated a direct correlation between CIDEA expression and fraction of large cells and an inverse correlation with small adipocytes number and pre-adipocytes proliferation. After gaining weight, we observed an increase in adipocytes cell diameter but a decrease in CIDEA expression, and the transcriptomic analysis showed a gene profile linked to adipocyte dysfunction. Together, these data suggested that in subjects with high VAT/(VAT+SAT) decreased CIDEA expression is associated with an increase in adipocyte cell sizing and consecutive insulin resistance.
