Abstract:


Background: MicroRNAs (miRNAs) play an important role in the pathogenesis of various renal diseases, including Chronic Kidney Diseases (CKD). CKD refers to the gradual loss of kidney function with the declining Glomerular Functional Rate (GFR).

Objective: This study focused on the regulatory mechanism of miRNA to control gene expression in CKD.

Methods: In this context, two lists of Differentially Expressed Genes (DEGs) were obtained; one from the three selected experiments by setting a cutoff p-value of <0.05 (List A), and one from a list of target genes of miRNAs (List B). Both lists were then compared to get a common dataset of 33 miRNAs, each had a set of DEGs i.e. both up-regulated and down-regulated genes (List C). These data were subjected to functional enrichment analysis, network illustration, and gene homology studies.

Results: This study confirmed the active participation of various miRNAs i.e. hsa -miR-15a-5p, hsa-miR-195-5p, hsa-miR-365-3p, hsa-miR-30a-5p, hsa-miR-124-3p, hsa-miR-200b-3p, and hsamiR- 429 in the dysregulation of genes involved in kidney development and function. Integrated analyses depicted that miRNAs modulated renal development, homeostasis, various metabolic processes, immune responses, and ion transport activities. Furthermore, homology studies of miRNA-mRNA hybrid highlighted the effect of partial complementary binding pattern on the regulation of genes by miRNA.

Conclusion: The study highlighted the great values of miRNAs as biomarkers in kidney diseases. In addition, the need for further investigations on miRNA-based studies is also commended in the development of diagnostic, prognostic, and therapeutic tools for renal diseases.
