Insulin Secretion in Acromegaly
The Journal of Clinical Endocrinology & Metabolism, 1970ABSTRACT A comparative study of insulin release was made in 9 acromegalic and 39 normal subjects who had normal fasting plasma glucoses. Both hyperglycemic (increase of plasma glucose of at least 25 mg/100 ml) and nonhyperglycemic stimuli were used. Those producing hyperglycemia included a 100 g oral glucose tolerance test and a glucose-protein meal ...

Extrapancreatic Insulin-Secreting Tumor
New England Journal of Medicine, 1964DOEGE1 reported, in 1930, the first case of fibro-sarcoma associated with hypoglyccmia; however, it was not until 1942 that the specific syndrome of spontaneous hypoglycemia associated with tumors of mesodermal origin was clearly recognized.2 Since that time 39 new cases have been described.3 The location of the tumors has been almost equally ...

Hypothermia and Insulin Secretion
Endocrinology, 1970The effect of decreased body temperature on insulin secretion was studied using the isolated perfused rat pancreas. It was found that hypothermia directly inhibits insulin release and that there exists a direct relationship between tissue temperature and total quantity of insulin released (in response to either glucose or tolbutamide stimulation).

SIK2 regulates insulin secretion
Nature Cell Biology, 2014Correct regulation of insulin secretion by the pancreas is crucial for organismal function and survival. The AMPK-related kinase SIK2 (salt-inducible kinase 2) is now shown to be stabilized in pancreatic β-cells following glucose stimulation, leading to improved systemic glucose homeostasis by regulating cellular calcium flux and insulin secretion.

Inhibition of Insulin Secretion
2005Reports of the effects of amylin and amylin agonists on insulin secretion have varied widely. Some confusion can be attributed to the use of human amylin, which has been shown to readily fall out of solution resulting in low estimates of bioactivity. Some confusion can be resolved by assessing the probability that this had happened. The view taken here,

Neuroendocrine Control of Insulin Secretion
Diabetes, 1976The effects of thyrotropin-releasing hormone, luteinizing hormone-releasing hormone, substance P, somatostatin, and a partially purified hypothalamic extract on insulin secretion were tested both in vitro and in vivo. Only somatostatin and the hypothalamic extract affected insulin secretion.

Multiscale Modeling of Insulin Secretion
IEEE Transactions on Biomedical Engineering, 2011Insulin secretion from pancreatic beta cells is a fundamental physiological process, and its impairment plays a pivotal role in the development of diabetes. Mathematical modeling of insulin secretion has a long history, both on the level of the entire body and on the cellular and subcellular scale.

Desensitization of insulin secretion
Biochemical Pharmacology, 2002Desensitization of insulin secretion describes a reversible state of decreased secretory responsiveness of the pancreatic beta-cell, induced by a prolonged exposure to a multitude of stimuli. These include the main physiological stimulator, glucose, but also other nutrients like free fatty acids and practically all pharmacological stimulators acting by

Metabolism, 1984
Recent advances in insulin secretion indicate that pertussis toxin abolishes the inhibition by alpha 2 adrenoceptor activation of insulin release by the pancreas. Pertussis toxin adenosine diphosphate (ADP) ribosylates an inhibitory guanine nucleotide-binding protein (Ni) involved in inhibition of adenylate cyclase.
