PG - E2510-7 LID - 10.1210/jc.2013-4349 [doi] AB - OBJECTIVE: Angiopoietin-like protein 8 (Angptl8) has recently been introduced as a novel adipokine/hepatokine that promotes pancreatic beta-cell proliferation and improves glucose tolerance in mouse models of insulin resistance. However, regulation of Angptl8 in human type 2 diabetes mellitus (T2DM) and renal dysfunction has not been determined. RESEARCH DESIGN AND METHODS: Serum Angptl8 levels were quantified by ELISA in 62 patients with T2DM as compared with 58 nondiabetic subjects in vivo. Within both groups, about half of the patients were on chronic hemodialysis or had an estimated glomerular filtration rate above 50 mL/min/1.73 m(2). Furthermore, we investigated the effect of insulin and differentiation on Angptl8 mRNA expression in 3T3-L1 adipocytes in vitro. RESULTS: Median [interquartile range] serum Angptl8 levels were higher in patients with T2DM (1.19 [0.37] mug/L) as compared with nondiabetic subjects (1.03 [0.47] mug/L) (P = .005). Furthermore, the adipokine/hepatokine was significantly higher in women (1.21 [0.47] mug/L) as compared with men (1.05 [0.44] mug/L]) (P = .013). In multivariate analysis, fasting glucose and T2DM but not renal function remained independent and positive predictors of circulating Angptl8 even after adjustment for markers of obesity, lipid status, and inflammation (P < .05). Furthermore, Angptl8 mRNA expression was induced by insulin and during adipogenesis in 3T3-L1 adipocytes in vitro. CONCLUSIONS: Circulating Angptl8 is positively and independently associated with T2DM and fasting glucose in vivo. Furthermore, Angptl8 mRNA expression is induced by insulin and during adipogenesis in 3T3-L1 adipocytes in vitro.
