  2. Glucokinase - Wikipedia

    en.wikipedia.org/wiki/Glucokinase

    Glucokinase in beta cells serves as a glucose sensor, amplifying insulin secretion as blood glucose rises. In the pancreatic beta-cell, glucokinase is a key regulator enzyme. Glucokinase is very important in the regulation of insulin secretion and has been known as the pancreatic beta-cell sensor.

  3. Insulin - Wikipedia

    en.wikipedia.org/wiki/Insulin

    Insulin is a major regulator of endocannabinoid (EC) metabolism and insulin treatment has been shown to reduce intracellular ECs, the 2-arachidonoylglycerol (2-AG) and anandamide (AEA), which correspond with insulin-sensitive expression changes in enzymes of EC metabolism. In insulin-resistant adipocytes, patterns of insulin-induced enzyme ...

  4. Beta cell - Wikipedia

    en.wikipedia.org/wiki/Beta_cell

    The triggering pathway of glucose-stimulated insulin secretion. In beta cells, insulin release is stimulated primarily by glucose present in the blood. [4] As circulating glucose levels rise such as after ingesting a meal, insulin is secreted in a dose-dependent fashion. [4] This system of release is commonly referred to as glucose-stimulated ...

  5. Insulin signal transduction pathway - Wikipedia

    en.wikipedia.org/wiki/Insulin_signal...

    The influx of Ca 2+ ions causes the secretion of insulin stored in vesicles through the cell membrane. The process of insulin secretion is an example of a trigger mechanism in a signal transduction pathway because insulin is secreted after glucose enters the beta cell and that triggers several other processes in a chain reaction.

  6. Mannoheptulose - Wikipedia

    en.wikipedia.org/wiki/Mannoheptulose

    Mannoheptulose has been reported to inhibit insulin secretion from pancreas. [7] This inhibition occurs because when mannoheptulose is present the glycolysis is inhibited (because there is no production of glucose-6-P) therefore no increase in ATP concentration which is required to close the KATP channel in the beta cells of the pancreas causing a diminution of calcium entry and insulin secretion.

  7. Glucokinase regulatory protein - Wikipedia

    en.wikipedia.org/wiki/Glucokinase_regulatory_protein

    GKRP binds and moves glucokinase (GK), thereby controlling both activity and intracellular location [1] [2] of this key enzyme of glucose metabolism. [3] GKRP is a 68 kD protein of 626 amino acids. It is coded for by a 19 exon gene, GCKR, on the short arm of chromosome 2 (2p23). GKRP was discovered by Emile van Schaftingen and reported in 1989 [4]

  8. Incretin - Wikipedia

    en.wikipedia.org/wiki/Incretin

    Incretins are released after eating and augment the secretion of insulin released from pancreatic beta cells of the islets of Langerhans by a blood-glucose–dependent mechanism. [1] Some incretins also inhibit glucagon release from the alpha cells of the islets of Langerhans. In addition, they slow the rate of absorption of nutrients into the ...

  9. Pancreatic beta cell function - Wikipedia

    en.wikipedia.org/wiki/Pancreatic_beta_cell_function

    Pancreatic beta cell function (synonyms G β or, if calculated from fasting concentrations of insulin and glucose, HOMA-Beta or SPINA-GBeta) is one of the preconditions of euglycaemia, i.e. normal blood sugar regulation. It is defined as insulin secretory capacity, i.e. the maximum amount of insulin to be produced by beta cells in a given unit ...
