Deficiency of phosphoinositide 3-kinase enhancer protects mice from diet-induced obesity and insulin resistance.

abstract：OBJECTIVE:Recent genome-wide association studies (GWASs) related common variants in the interleukin-6 (Il-6) receptor (IL6R) gene to plasma C-reactive protein (CRP) concentrations. Because IL6R variants were previously associated with IL-6 levels, we tested whether the associations with CRP were independent of IL-6 and...

The effects of circulating IGFs on the vasculature are largely modulated by IGFBPs, which control their access to cell-surface IGF receptors. IGFBP-1 has been proposed as the acute regulator of IGF bioavailability because of its me...
