Hypoglycin stimulates insulin secretion

PACAP stimulates insulin secretion but inhibits insulin sensitivity in mice.

Although pituitary adenylate cyclase-activating polypeptide (PACAP) stimulates insulin secretion, its net influence on glucose homeostasis in vivo has not been established. We therefore examined the action of PACAP-27 and PACAP-38 on insulin secretion, insulin sensitivity, and glucose disposal as derived from the minimal model of glucose disappearance during an intravenous glucose tolerance tes...

Thrombin stimulates insulin secretion via protease-activated receptor-3

The disease mechanisms underlying type 2 diabetes (T2D) remain poorly defined. Here we aimed to explore the pathophysiology of T2D by analyzing gene co-expression networks in human islets. Using partial correlation networks we identified a group of co-expressed genes ('module') including F2RL2 that was associated with glycated hemoglobin. F2Rl2 is a G-protein-coupled receptor (GPCR) that encode...

Bombesin stimulates insulin secretion by a pancreatic islet cell line.

The amphibian tetradecapeptide, bombesin (BBS) has been shown to stimulate insulin secretion both in vivo and by pancreatic islet cells in vitro. To determine whether BBS can act directly on pancreatic beta cells, we examined its effects on insulin secretion by HIT-T15 cells (HIT cells), a clonal islet cell line. Addition of 100 nM BBS to HIT cells stimulated insulin release 25-fold within 30 s...

Groningen PACAP stimulates insulin secretion but inhibits insulin sensitivity in mice

Asparagus adscendens (Shweta musali) stimulates insulin secretion, insulin action and inhibits starch digestion.

Diabetes mellitus is a complex metabolic disease characterised by glucose overproduction and under-utilisation. As the incidence of diabetes expands rapidly across the globe there is an urgent need to expand the range of effective treatments. Higher plants such as Asparagus adscendens provide therapeutic opportunities and a rich source of potential antidiabetic agents. In the present study an a...
