Glucose-stimulated insulin secretion, controlled by multiple protein phosphorylation events, is critical for the regulation of glucose homeostasis. Protein kinase A (PKA) is known to play a role in β cell physiology, but the role of its anchoring protein is not fully understood. Hinke et al (2012) illustrate the significance of A-kinase anchoring protein 150 in tethering protein phosphatase 2B ...

Genetic ablation studies confirmed the role of central insulin-receptor signaling (CIRS) in fuel metabolism. However, the need to examine the role of CIRS in glucose homeostasis under normal physiological condition is indispensable, as insulin affects the neuronal growth, differentiation and synaptic plasticity. Intracerebral administration of S961 induced hyperglycemia and glucose intolerance ...

Dopaminergic signaling is one of the regulatory pathways being investigated for its implication in glucose metabolism. The aim of this study was to determine the effect of cabergoline on biochemical and anthropometric parameters in prediabetes stage (impaired fasting glucose and impaired glucose tolerance). In this double blind, placebo-controlled, pilot study, 27 prediabetic adults were random...
