polymorphism in the angiotensin-converting enzyme (ace) gene and ace activity in type 2 diabetic patients
Authors
abstract
diabetes mellitus is a multifactorial disease. it has recently been shown that an insertion (i)/deletion (d) polymorphism exists in the angiotensin-converting enzyme (ace) gene that can affect the serum ace level. there are three genotypes: dd, di, and ii, with the ace level being highest in dd, intermediate in di, and lowest in ii. in the present investigation, 170 patients with type 2 diabetes mellitus (t2dm) and 144 control subjects were studied. the ace i/d polymorphism was determined by polymerase chain reaction (pcr) utilizing specific primers. ace activity was determined spectrophotometrically. distribution of ace gene (i/d) polymorphism and allele frequencies in patients with t2dm were significantly different from those in control ( p in genotype distribution between the two groups ( p for each genotype. moreover, we found test sensitivity to be 62.3%. serum ace activity was significantly associated with ace (i/d) gene polymorphism.

Angiotensin Converting Enzyme Gene Polymorphism in Iranian Patients with Type 2 Diabetes
Background: Angiotensin I converting enzyme (ACE) is a Zinc metalloproteinase, converts Ang-I to Ang- II, a pro-inflammatory agent which may contribute to pathophysiology of some diseases like type 2 diabetes. Objective: To investigate the relationship between ACE I/D polymorphism and type 2 diabetes in 261 Iranian casecontrol pairs. Methods: 170 patients (85 type 2 diabetics with nephropathy a...

An insertion/deletion (I/D) polymorphism of the angiotensin converting enzyme (ACE) gene is associated with plasma ACE levels in white populations. The occurrence of the I/D polymorphism and relationship to ACE levels was examined in a Pima Indian group (n = 305). The frequency of the D allele was lower in Pimas than whites (0.29 v 0.52 respectively). ACE levels were significantly associated wi...

INTRODUCTION Although proteinuria is traditionally regarded as the result of glomerular damage, recent evidence suggests that proteinuria can directly cause renal damage through lysosomal injury, growth factor induced tubular fibrosis and transcriptase genes which trigger vasoactive and inflammatory renal damage. The renin angiotensin system which releases angiotensin, a most powerful vasoconst...

OBJECTIVE An insertion/deletion (I/D) variant in the angiotensin-converting enzyme (ACE) gene was associated with ACE inhibitor (ACEI)-related cough in previous studies. However, the results were inconsistent. Our objective was to assess the relationship between the ACE I/D polymorphism and ACEI-related cough by meta-analysis and to summarize all studies that are related to ACE I/D polymorphism...
