The Islets of Langerhans try to adapt themselves to this condition by increasing the number of insulin-producing beta-cells and/or modulating their individual secretion of insulin in response to the intake of sugar.
Metabolic diapause in pancreatic beta-cells expressing a gain-of-function mutant of the forkhead protein Foxo1.
Within the cells are SNARE proteins, which are the machinery that helps the beta-cells release the insulin to try and stabilise blood glucose levels.
Louis, led by Michael McDaniel, PhD, and Nidhi Rohatgi, PhD, found this next generation insulin sensitizer may provide physicians with a new tool for the treatment of diabetes that relieves insulin resistance in human islets, thereby preserving the survival and function of human beta-cells.
Thanks to previous research, they knew that when the insulin pathway is blocked in the liver, there's some process that induces the pancreas to make more insulin-secreting beta-cells in response.
The curcumin group had better functioning of beta-cells (cells of the pancreas that store and release insulin and C-peptide), decreased insulin resistance and higher adiponectin levels compared to the placebo group.
They discuss growth factor pathways, especially the insulin and insulin-like growth factor signaling mechanisms affecting Beta-cells in diabetes; models to confirm that proliferation is a major mechanism underlying regeneration in rodents; findings on cell cycle control; proteins downstream of the growth factor pathways in the regulation of Beta-cell biology; and the roles of other growth factors in modulating Beta-cell growth.
But McCarthy said one particularly important theme of their findings was that several of the genes seem to be important in controlling the number of pancreatic beta-cells a person has.
Study leader Professor Mark McCarthy, from Oxford University said: "One important theme is that several of the genes seem to be important in controlling the number of pancreatic beta-cells that an individual has.
showed that GLP-1 can cause islet stem cells to differentiate into pancreatic beta-cells, the insulin- secreting cells that are depleted or compromised in diabetes.
The researchers say the their research could ultimately result in the creation of an unlimited supply of beta-cells (the insulin-producing part of pancreatic islet cells) for transplantation into people with diabetes.
