Importance: Primary open angle glaucoma, an age-related, retinal neurodegenerative disease of unknown etiology, is treated by lowering intraocular pressure, even though elevated pressure present in only about 60% patients. Since we found that tolbutamide, which inhibits the opening ATP-sensitive potassium channels, modulates aqueous dynamics with a significant increase outflow, and since aquapo...

Type 2 diabetes mellitus (T2DM) is a complex metabolic disease characterized by high blood glucose levels due to impaired insulin secretion or resistance. Polymorphisms in the ABCC8 gene rs1799854 are widely found have an association with T2DM, where encodes SUR1 protein from K-ATP channel that plays role cells β pancreas. Mutations can cause potassium channels and secretions problems possibly...

Congenital hyperinsulinism (CHI) is biochemically characterised by the dysregulated secretion of insulin from pancreatic beta-cells. It is a major cause of persistent hyperinsulinaemic hypoglycaemia (HH) in the newborn and infancy period. Genetically CHI is a heterogeneous condition with mutations in seven different genes described. The genetic basis of CHI involves defects in key genes which r...

OBJECTIVE The purpose of this study was to investigate whether genetic variants could influence the antidiabetic efficacy of gliclazide in type 2 diabetic patients. RESEARCH DESIGN AND METHODS A total of 1,268 type 2 diabetic patients whose diabetes was diagnosed within the past 5 years and who had no recent hypoglycemic treatment were enrolled from 23 hospitals in China. All of the patients ...

N eonatal hyperinsulinism is the most important cause of hypoglycemia in infancy (1,2). The inappropriate oversecretion of insulin is responsible for profound hypoglycemia, requiring aggressive treatment to prevent brain damage (1–3). Neonatal hyperinsulinism is often resistant to medical therapy (1–4), and pancreatectomy is required for many sufferers (1,5–6). The histopathological lesions ass...

OBJECTIVE Permanent neonatal diabetes (PND) is defined by chronic hyperglycemia due to severe nonautoimmune insulin deficiency diagnosed in the first months of life. Several genes, including KCNJ11 and ABCC8, which encode the two subunits of the ATP-sensitive K(+) channel (K(ATP) channel) can cause PND. Mutations in the insulin (INS) gene have been recently described in families with neonatal d...

ATP-sensitive K(+) (K(ATP)) channels are composed of pore-forming subunits (Kir6.x) and of regulatory subunits, the sulfonylurea receptors (SURx). Subtypes of K(ATP) channels are expressed in different organs. The sulfonylureas and glinides (insulinotropes) close the K(ATP) channel in pancreatic beta-cells and stimulate insulin secretion. The insulinotrope binding site of the pancreatic channel...

Neonatal diabetes mellitus (NDM) is a rare kind of diabetes characterized by hyperglycemia and low levels of insulin. Clinically, it is categorized into two main types: transient NDM (TNDM) and permanent NDM (PNDM). These types are diagnosed based on duration of insulin dependence early in the disease. In TNDM, diabetes begins in the first few weeks of life with remission in a few months. Howev...
