"Data suggest that compared with obese white women obese black women exhibit higher expression of HIF1A (hypoxia inducible factor 1 alpha) COL5A1 (collagen Valpha1) and COL6A1 (collagen VIalpha1) in gluteal but not abdominal subcutaneous adipose tissue depots; up-regulation of expression of these proteins correlates with reduced insulin sensitivity in black women only."xsd:string
