[Influence of polymorphism pro12Ala of PPARgamma gene on endothelium destruction in patients with diabetes mellitus t. 2].

UNLABELLED

The peroxisome proliferator-activated receptor gamma (PPARgamma) influences wide on metabolism and atheromatosus processes in vessels. The common polymorphic form of PPARy, Pro12Ala, could promote diabetes mellitus and diabetic vascular complications.

AIM OF WORK

The assessment of indicators of endothelium destruction in patients with diabetes mellitus t.2 in relation to the polymorphism Pro12Ala of PPARgamma.

PATIENTS AND METHODS

Circulating blood endothelium cells (immunofluorescens method with MoAb CLB-HEC19), thrombomodulin (Asserchrom Immunoassay) and polymorphism Pro12Ala [minisequence technic SnaPshot (Applera); ABI+PRISM310] were investigated in 58 patients with diabetes mellitus typ 2 and 22 healthy persons. Fibrinogen, uric acid, lipids, HbA1c, glucose, insulin concentration, blood pressure, BMI and WHR were evaluated too.

RESULTS

The significant higher systolic (137.92 +/- 15.88 vs 122.0 +/- 15,67 [mmHg]; p < 0.025) and diastolic (85.00 +/- 7.38 vs 75.50 +/- 7.61 [mmHg]; p < 0.011) was determined in the group of healthy people, who have got a homozygous genotyp Pro12Pro in comparison with heterozygous genotyp Pro12Ala. The significant higher value of HbA1c was determined in the patients with diabetes mellitus t.2, who have got genotyp Pro12Ala in comparison with genotyp Pro12Pro (7.01 +/- 1.54 vs 8.39 +/- 1.81 [%]; p < 0.006). There was any significant difference for others parameters. Among people, which have got genotyp Pro12Pro there was significant difference between healthy and patients for circulating blood endothelium cells (2.19 +/- 1.53 vs 0.78 +/- 0.09 [EC/ml]; p < 0.009). On the contrary among people with genotype Pro12Ala there was not significant difference between healthy and patients for circulating blood endothelium cells (2.95 +/- 1.64 vs 1.61 +/- 1.08; p = 0.077 [EC/ml]).

CONCLUSIONS

1. The polymorphism Pro12Ala is not connected with the endothelium destruction. 2) Other researches are necessary to estimate influence of mutated allele on the control of diabetes. 3) The genotyp Pro12Pro promotes higher blood pressure by healthy people.
