ABSTRACT

Objectives: To study expression of glyoxalase I in patients of diabetic retinopathy. Methods: This cross-sectional comparative study was conducted at Services Hospital Lahore, Pakistan from January 2015 to November 2015. Sampling technique was non- probability purposive sampling. Total 60 subjects were enrolled in two groups. Group-I comprised 30 patients of diabetic retinopathy and Group-II of 30 normal healthy controls. Clinical and demographic data was collected and fasting venous blood samples (2 ml) were drawn. RNA was extracted and subjected to cDNA synthesis. Expression analysis for glyoxalase I was carried out and relative quantification done by double delta Ct method. Results: Mean age of the patients was 61.30 ±7.06 years and mean age of controls was 59.60 ± 6.43 years. There were 17 (56.7%) males and 13 (43.3%) females in Group-I while Group-II comprised 14 (46.7%) males and 16 (53.3%) females. There was down regulation of glyoxalase I among patients of diabetic retinopathy in comparison with controls when relative gene expression was calculated. Conclusion: Down regulation of glyoxalase I in patients of diabetic retinopathy suggests it to be a contributory factor in the development of disease.
