There is insufficient evidence from previous studies about the role of several circulating microRNAs (miRNAs) in the early development of DN. This study aimed to describe the expression of miRNA-377, miRNA-93, miRNA-25, miRNA-216a, and miRNA-21 in a sample of type 1 diabetic children and adolescents to explore their association with DN and some indices of kidney injury.Patients and Methods: Seventy type 1 diabetic patients, with 5 years’ duration of diabetes or more, were recruited from Children’s Hospital, Faculty of Medicine, Cairo University. Quantitative real-time reverse-transcription PCR (qRT-PCR) was used to measure the expression of the above mentioned miRNAs in serum and to assess its association with DN, and the studied risk factors.Results: There was a significantly higher percentage of up-regulation of miRNA-377 and miRNA-93 (P=0.03, 0.02, respectively) in addition to significant down-regulation of miRNA-25 (P=0.01) in patients with DN than in patients without DN. In patients with DN, expression of miR-216a was significantly negatively correlated with creatinine (r=− 0.4, P=0.04) and positively correlated with eGFR using creatinine (r=0.5, P=0.03). In the same group, expression of miR-21 was positively correlated with urinary cystatin C (r=0.6, P=0.01) and was negatively correlated with e-GFR using cystatin c (r=− 0.6, P=0.01). miRNA-93 was associated with increased risk (odds ratio=15, 95% CI=12.03– 24.63, P=0.01), while miRNA-25 was associated with decreased risk for albuminuria (odds ratio=0.15, 95% CI=0.08– 0.55, P=0.03).Conclusion: miRNA-377, miRNA-93, miRNA-216a, and miRNA-21 may be implicated in the pathogenesis of DN, while miRNA-25 may have a reno-protective role. More studies are needed to document the value of these miRNAs as diagnostic biomarkers as well as therapeutic targets in DN.Keywords: microRNAs, type 1 diabetes, diabetic nephropathy, albuminuria, childrenAbdelghaffar SShora HAbdelatty SElmougy FEl Sayed RAbdelrahman HSoliman HAlgebaly HAhmed SAlfy PElshiwy YDove Medical Pressarticlemicrornas – type 1 diabetes – diabetic nephropathy – albuminuria - childrenSpecialties of internal medicineRC581-951ENDiabetes, Metabolic Syndrome and Obesity: Targets and Therapy, Vol Volume 13, Pp 2485-2494 (2020) |
