11HSD1 regenerates cortisol from cortisone and maintains glucocorticoid receptor (GR) activation. Adipose-specific transgenic 11HSD1 overexpression in mice causes obesity, insulin resistance, and hypertension (reflecting increased adipose angiotensinogen); however, the effect depended upon local GR expression. In human obesity, 11HSD1 activity is increased similarly in biopsied adipose, but the impact remains uncertain. We tested whether increased adipose 11HSD1 activity in ob...

Intra-adipose steroid metabolism may be a key determinant of accumulation and distribution of body fat. Adverse 'central' fat can be driven by glucocorticoid excess or decreased oestrogen/androgen ratio. We previously demonstrated increased regeneration of cortisol by 11beta-HSD1 in adipose in human obesity. Here, we measured mRNAs for enzymes dictating local activation of oestrogens (aromatase) and androgens (5alpha-reductase type 1) in subcutaneous human adipose and related ...
