MicroRNA (hsa-miR-19b-2-5p) targets key mitochondrial biogenesis genes-a bioinformatics analysis

The present study on the basis of a detailed bioinformatics analysis proposed a potential role of a miRNA, hsa-miR-19b-2-5p, in regulating the mitochondrial biogenesis. The miRNA has shown to be involved in important biological processes of cellular metabolic, cellular macromolecule biosynthetic processes and gene expression pathways. The miRNA, hsa-miR-19b-2-5p, was predicted to regulate the molecular function of nucleic acid, organic/heterocyclic compound, nucleic acid binding transcription factor activity. The pathway enrichment analysis suggested that this miRNA participated in several metabolic pathways which could be a key to the regulation of the mitochondrial gene expression and biogenesis. In addition, this miRNA targets a total of 112 mitochondria-related genes, establishing further the crucial role of the candidate miRNA in mitochondrial biology.
