| الملخص: | Aim: To study the signature of 87 urinary miRNAs in Duchenne muscular dystrophy (DMD) patients, select
the most dysregulated and determine statistically significant differences in their expression between
controls, ambulant (A) and nonambulant (NA) DMD patients, and patients on different corticosteroid
regimens. Patients/materials & methods: Urine was collected from control (n = 20), A (n = 31) and NA
(n = 23) DMD patients. miRNA expression was measured by reverse transcription-quantitative PCR. Results:
miR-29c-3p was significantly downregulated in A DMD patients while miR-23b-3p and miR-21-5p
were significantly downregulated in NA DMD patients compared with age-matched controls. Conclusion:
miR-29c-3p, miR-23b-3p and miR-21-5p are promising novel noninvasive biomarkers for DMD, and miR-
29c-3p levels are differentially affected by different steroid regimens, supporting the antifibrotic effect
of steroid therapy.
