Article: The relationship of the apolipoprotein E gene polymorphism Turkish Type 2 diabetic patients with and without nephropathy.
[show abstract] [hide abstract]
ABSTRACT: Apolipoprotein E (ApoE) genetic variation which is a major constituent of plasma lipoproteins causes diabetic nephropathy progress. Chronic kidney disease is associated with increased E2 allele and the decreased E4 allele risk. The aim of this study was to investigate the association between ApoE gene polymorphism in the development of diabetic nephropathy in Type 2 diabetes Turkish patients. The objective of the study is to investigate the influence of ApoE gene polymorphism in the development of diabetic nephropathy in Turkish Type 2 diabetes. The ApoE genotypes were determined retrospectively in 46 patients with nephropathy and 56 without nephropathy and a control group of 35 healthy individuals. Genomic DNA was extracted from peripheral leukocytes of the subjects using the High Pure PCR Template Preparation Kit. For the detection of the presence of the three ApoE E alleles epsilon2, epsilon3, and epsilon4 (codon 112 and 158) were analyzed by the commercial LightCycler ApoE Mutation Detection Kit. No differences in ApoE genotype or the allelic frequencies of epsilon2, epsilon3 or epsilon4 were found between the Type 2 diabetic patient group (with and without nephropathy) and a control group. We conclude that the ApoE gene polymorphism is not associated with the development of diabetic nephropathy in Turkish Type 2 diabetic patients. Lack of association between ApoE gene polymorphism and Type 2 diabetic nephropathy might be due to ethnic differences.Journal of endocrinological investigation 04/2009; 32(3):219-22. · 1.57 Impact Factor -
Article: Association of the angiotensinogen M235T and angiotensin-converting enzyme insertion/deletion gene polymorphisms in Turkish type 2 diabetic patients with and without nephropathy.

ABSTRACT: Recent studies have suggested an association between a deletion variant of the angiotensin-converting enzyme (ACE) gene and diabetic nephropathy. However, this finding has not been confirmed by all investigators. Furthermore, an M235T variant of the angiotensinogen (AGT) gene has been associated with hypertension, an important risk factor for the development and progression of diabetic nephropathy. We investigated the relationship of the ACE insertion/deletion (I/D) and AGT M235T gene polymorphisms in Turkish patients with type 2 diabetes mellitus (DM) with and without diabetic nephropathy. A total of 102 individuals were screened for the presence of the ACE I/D and AGT M235T polymorphism: 46 individuals who had type 2 DM with diabetic nephropathy and, as controls, 56 individuals who had type 2 DM without diabetic nephropathy. Gene polymorphisms were determined by the specific melting temperature (T(m)) values of the resulting amplicons after real-time online polymerase chain reaction and melting curve analysis. The frequencies of the ACE DD, ID, and II genotypes were 34.8%, 37.0%, and 28.3%, respectively, among type 2 diabetic patients with nephropathy, and 33.9%, 42.9%, 23.2%, respectively (P=.788), in the control subjects without diabetic nephropathy. On the other hand, the frequencies of the AGT MM, MT, and TT genotypes among the same groups were 26.1%, 52.2%, 21.7% and 26.8%, 57.1%, 16.1%, respectively (P=.758). There were no differences in the frequencies of the AGT M235T and ACE I/D genotypes between Turkish patients with type 2 DM with and without nephropathy.Journal of Diabetes and its Complications 22(3):186-90. · 2.03 Impact Factor
