INTRODUCTION: We aimed to explore the diagnostic values of mir-192 and mir-145
miRNAs in patients with diabetic nephropathy (DN) and Focal Segmental
Glomerulosclerosis (FSGS).
METHODS: Patients aged between 40-65 years who had 24-h protein excretion > 1.0
g/day and creatinine clearance > 30 ml/min were included in this study. Urine samples
are collected from 9 patients (1 F, 8M; mean age 54.661.5) with Type 2 diabetes
mellitus, 7 patients (6 F, 1M; mean age 55,1+7,8) with FSGS and 4 healthy individuals
(1 F, 3M; mean age 48.264.8). Isolation of target miRNAs mir-192 and mir-145 were
performed using targeted assays from urinary exosomes then quantitative profiling of
isolated miRNAs performed by quantitative
RESULTS: Creatinine clearance and 24-h protein excretion were found as 45.6624.3
ml/min and 6.6763.17 g/day in Type 2 diabetic patients and as 72,5631,9 ml/min and
2,4761,33 g/day in FSGS patients, respectively. Real Time-PCR data were obtained
from patients with healthy controls. All target CT values were normalized according to
housekeeping gene and 2^-DCT values were calculated. Comparative 2^-DCT values
between data groups are shown in Figure 1. mir-145 levels were found to be
upregulated in DN (mean 2^-DCT 0.5660,2) compared to FSGS (mean 2^-DCT
0.0960,03) and healthy group (mean 2^-DCT 0.0860,06). Also mir-192 levels were
found to be upregulated in DN (mean 2^-DCT 3.1162) compared to FSGS (mean 2^-
DCT 1.3261) and healthy group (mean 2^-DCT 2.6561.2). mir-145 levels were found
to be upregulated in DN (mean 2^-DCT 0.5660,2) compared to FSGS (mean 2^-DCT
0.0960,03) and healthy group (mean 2^-DCT 0.0860,06). Also mir-192 levels were
found to be upregulated in DN (mean 2^-DCT 3.1162) compared to FSGS (mean 2^-
DCT 1.3261) and healthy group (mean 2^-DCT 2.6561.2). However, there were no
statistically significant differences among groups.
CONCLUSIONS: We have seen a trend in increase of both mir-145 and mir-192 levels
in DN patients compared to healthy group. We are further analyzing our data with
increased sample size.
