    AROMATASE ACTIVITY IN ADIPOSE TISSUE
    Aromatase is an enzyme present in many tissues, but particularly
    in adipose tissue. Specifically, this enzyme, aromatase
    cytochrome P450, is encoded by the CYP19 gene.23 This
    converts androgens to oestrone and oestradiol.
    Adipose tissue contains adipocytes that carry the accumulated
    fat burden itself, as well as stromal cells, which are relatively
    thinly dispersed blood vessels and fibroblasts. It appears
    that 90% of the aromatase activity in fatty tissue is found in
    the stromal cells, particularly the fibroblasts,24 although some
    is also found in monocyte derived macrophages.25 Of some
    importance is the fact that the fractional conversion of
    androstenedione to oestrogens in obese subjects may not
    decrease after weight loss, probably because the number of
    stromal cells in the remaining adipose tissue does not appreciably
    decrease.24 26 Furthermore, aromatase activity and its
    expression in adipose tissue is markedly potentiated by
    various promoters,27 as well as by the cytokine IL-6 and
    tumour necrosis factor (TNF).28 29 Adipose stromal cells from
    omental fat, but not subcutaneous fat, have been shown to
    generate active cortisol from inactive glucocorticosteroids
    through the expression of the enzyme 11-b-hydroxy steroid
    dehydrogenase.30 These active glucocorticoids further encourage
    aromatase activity.31 Other workers have shown that
    aromatase activity, at least in subcutaneous adipose tissue, is
    higher in men than women.32 The rate of conversion of testosterone
    to oestrogen in omental tissue appears to be slower
    than in other adipose tissue sites, although the final
    concentrations of oestrogens in both sites are similar.24
