145 results about "Glucokinase" patented technology

Glucokinase (EC 2.7.1.2) is an enzyme that facilitates phosphorylation of glucose to glucose-6-phosphate. Glucokinase occurs in cells in the liver and pancreas of humans and most other vertebrates. In each of these organs it plays an important role in the regulation of carbohydrate metabolism by acting as a glucose sensor, triggering shifts in metabolism or cell function in response to rising or falling levels of glucose, such as occur after a meal or when fasting. Mutations of the gene for this enzyme can cause unusual forms of diabetes or hypoglycemia.

New plasma membrane biomarkers preferentially expressed in pancreatic beta cells useful in imaging or targeting beta cells

The present invention is directed to the identification of a biomarker specifically located in the plasma membrane of pancreatic beta cells. It was selected by a Systems Biology approach on Massively Parallel Signal Sequencing datasets obtained in human islets and Affymetrix microarray datasets on human islets, purified rat primary beta and non beta cells and insulinoma cells. Based on a set of specific features the biomarker is a unique candidate for imaging and targeting strategies to study the pancreatic beta cell mass in health and disease (T1 D, T2D, pancreatic cancers, obesity, islet transplantation, beta cell regeneration). The five specific features of the selected biomarkers are: 1) Preferentially expressed in pancreatic islets as compared to surrounding tissues; 2) Higher expression in pancreatic beta cells than in pancreatic alpha cells or than in other islet non-beta cells; 3) Expression levels in pancreatic beta cells are higher or comparable to glucokinase which is an enzyme specifically expressed in the pancreatic beta cell; 4) Located in the membrane and as such targetable with antibodies, peptides or small molecules which allows imaging, targeting and immunohistochemistry; and 5) Expression is not induced during the process of inflammation of the beta cell mass and the protein is not enriched in T-cells and dendritic cells or in other cells participating in the inflammation process.

Application of leonurine to preparation of medicament for treating 2-type diabetes

The invention belongs to the field of traditional Chinese medicine manufacturing, and relates to application of leonurine to preparation of a medicament for treating 2-type diabetes. Animal experiments prove that the fasting blood glucose of a 2-type diabetes mouse, i.e., a db / db mouse, can be lowered by the leonurine, and the tolerance of oral glucose is improved; and meanwhile, fasting plasma insulin is increased, the plasma triglyceride is reduced and the content of the plasma high-density lipoprotein is increased. Experiment results also show that the expression of liver glucose metabolic enzymes such as glucokinase, glucose-6-phosphatase and phosphoenolpyruvate carboxyl enzyme is adjusted by the leonurine in an Akt dependent mode; and the biological response of an inflammatory mediator, such as generation of TNF (Tumor Necrosis Factor)-alpha, degradation of IkB-alpha and subsequent phosphorylation of NF-kBp65, is suppressed. Through the leonurine, the inflammatory state of the 2-type diabetes can be corrected, and the symptoms of the 2-type diabetes can be improved; and the leonurine can be used as a treatment medicament to be applied to the treatment of the 2-type diabetes.
