Increased serum CXCL1 and CXCL5 are linked to obesity, hyperglycemia, and impaired islet function.

ABSTRACT: Proinflammatory cytokines are thought to play a significant role in the pathogenesis of type 2 diabetes (T2D) and are elevated in the circulation even before the onset of the disease. However, the full complement of cytokines involved in the development of T2D is not known. In this study, 32 serum cytokines were measured from diabetes-prone BKS.Cg-m+/+Lepr(db)/J (db/db) mice and heterozygous age-matched control mice at 5 weeks (non-diabetic/non-obese), 6-7 weeks (transitional-to-diabetes), or 11 weeks (hyperglycemic/obese) and then correlated with body weight, blood glucose, and fat content. Among these 32 cytokines, C-X-C motif ligand 1 (CXCL1) showed the greatest increase (+78%) in serum levels between db/db mice that were hyperglycemic (blood glucose: 519±23 mg/dl, n=6) and those that w
