Preferential accumulation of fat in the upper body (apple shape) is associated with higher risk of developing metabolic syndrome relative to lower body fat (pear shape). We previously discovered that chromatin openness defined partially the transcriptome of pre-adipocytes isolated from abdominal and gluteofemoral fat. However, the molecular mechanisms underlying inter individual fat repartition variation are unknown. Adipocyte fraction was isolated from abdominal and gluteofemoral fat biopsies of premenopausal women (age and BMI-matched) segregated initially only by their waist to hip ratio. We evaluated transcriptomic and chromatin accessibility using RNA-seq and ATAC-seq along with key clinical parameters. Our data showed that higher lower body fat mass was associated with better lipid profile and free fatty acid turnover after glucose administration. 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.

Figure S1: Depot-specific gene expression in adipocytes. (A and B) - Heat map representation of depot-specific gene expression determined by RNA-seq from the abdominal (ABD) and gluteofemoral (GF) depots in the 5 apple (left side, in red) and 5 pear-shaped women (right side, in blue). (C and D) - Venn diagrams depict number of genes up-regulated in each depot only in apples (red circle), only in pears (blue circle) or in both groups (intersection).
