Early signs of harm usually stay unnoticed till it has reached sophisticated stages of illness. Identifying early biomarkers of disease will let clinicians to detect the progression of illness before the onset of complications. Circulating microRNA contained in extracellular vesicles which include exosomes are potential early biomarkers and can be targeted to prevent diabetes from progressing. The aim of our project is always to validate and ascertain the part of miR-15a as a potential early biomarker in diabetic retinopathy. Methods: This project was approved by the University of Malaya Health-related Centre (UMMC) Healthcare Investigation Ethical Committee. A total of about 100 subjects (controls and sufferers with Type 2 DM) was recruited from UMMC, Kuala Lumpur. All subjects underwent full eye CD74 Proteins Molecular Weight examination and graded for diabetic retinopathy. Clinical details collected incorporated HbA1C, renal function testing, hypertension and smoking. Extracellular vesicle (EV) isolation was performed applying differential ultracentrifugation and quantified. Benefits: Within this study, we analysed miR-15a concentrations in plasma and exosomal-enriched fractions applying droplet digital and real-time PCR. There was no distinction in microRNA levels in plasma observed. Even so, there was a considerable improve in exosomal concentration (typical diameter 130nM) in individuals with diabetic retinopathy when compared with controls (p 0.05). There was also an rising trend of miR-15a level amongst diabetic sufferers compared to controls. Summary/Conclusion: The findings from this study corroborated with our preceding findings of improve in miR-15a levels in diabetes prior to the onset of retinopathy compared to controls. This suggests that miR15a is involved inside the early development of diabetic microvascular complications and may perhaps be a prospective biomarker for early complications of diabetes. Funding: 1.
