Specific insulin and proinsulin secretion in glucokinase-deficient individuals
Pardini,V.C.; Velho,G.; Reis,R.; Purisch,S.; Blanché,H.; Vieira,J.G.H.; Moisés,R.C.S.Glucokinase (GCK) is an enzyme that regulates insulin secretion, keeping glucose levels within a narrow range. Mutations in the glucokinase gene cause a rare form of diabetes called maturity-onset diabetes of the young (MODY). An early onset (less than 25 years), autosomal dominant inheritance and low insulin secretion stimulated by glucose characterize MODY patients. Specific insulin and proinsulin were measur...
Fetal hemoglobin levels are related to metabolic control in diabetic subjects
Pardini,V.C.; Victória,I.M.N.; Pieroni,F.B.; Milagres,G.; Nascimento,P.D.; Velho,G.; Purisch,S.; Pardini,H.We have investigated the relationship between fetal hemoglobin (HbF) levels and metabolic control in subjects with insulin-dependent (N = 79) and non-insulin-dependent diabetes mellitus (N = 242). HbF and hemoglobin A1c (HbA1c) levels were increased in subjects with type 1 and type 2 diabetes as compared to levels in nondiabetic individuals (P<0.0001), and were significantly higher in type 1 than in type 2 d...
