Dynamic interplay of microRNA in diseases and therapeutic.

MicroRNAs are the major class of small non-coding RNAs, evolutionary conserved post-transcriptional regulators of gene expression. Since their discovery in 1993, they have been implicated as master regulators in numerous cellular processes. MicroRNA (miRNA)s regulate gene expression by attenuation and/or mRNA degradation and are commonly associated with cell development, differentiation, and homeostasis. Extensive research in past two decades has provided new insights into the potential implications of miRNA in the onset, progression, and therapeutic nature of miRNAs in disease manifestation. Owing to the novel discoveries, "miRNAs" would probably pave a new direction in therapeutic research. However, "micro" in length miRNAs have attracted considerable attention in numerous other fields. Understanding the functionality of miRNAs, in this review article, we discussed the mechanistic role of miRNAs in human diseases and have outlined most of the recent published work in clinical therapeutics. We have constructed different network models for miRNA and its targets which made us understand their interrelationship and association with diseases. Future research would surely overcome challenges and would introduce new strategies for the utility of miRNAs in a broader setting.
