Metabolic Syndrome (MS) is reaching epidemic proportions with significant social
and economical burden worldwide. Since the molecular basis of MS remains poorly
defined, we investigated the impact of KAP, a kidney specific androgen-regulated
gene, in the development of high fat-diet (hfd)-induced MS. Tg mice
overexpressing KAP specifically in proximal tubule cells of the kidney exhibited
reduced body weight and lower liver and adipose tissue weight compared to control
littermates when fed a hfd. KAP Tg mice showed diminished adipocyte hypertrophy
and reduced hepatic steatosis, significantly correlating with expression of
relevant molecular markers and lower lipid content in liver. KAP transgenic were
protected from hfd-induced insulin resistance, increased blood pressure and
exhibited lower IL-6 serum levels and diminished expression of inflammatory
markers in the adipose. Moreover, KAP was localized in the secretory pathway of
proximal tubule cells and it is released to the extracellular media, preventing
IL-6 induction and STAT-3 activation upon TNF? stimulation. We conclude that KAP,
which might act as a hormone-like product in extra-renal tissues, protects Tg
mice against hfd-induced MS by preventing inflammatory related events that are
mediated, in part, through the IL-6 pathway.
