Abstract

miRNAs are a group of noncoding small RNA that are capable of modulating the expression of hundreds of genes via a near-perfect or partial complementary to target mRNA. The ability to regulate multiple targets simultaneously makes miRNA a crucial regulator in many physiological conditions, especially in the aging network and process. The tremendous capability of miRNA supports its ability in regulating ageing, which is a complex process involving multiple interconnected signaling pathways. Even though the relationship between miRNA and ageing is not fully understood, studies have provided evidence showing that miRNAs participate in regulating cell cycle progression, proliferation, stemness gene expression, and stress-induced responses. Molecular studies of ageing and miRNAs would provide a more comprehensive understanding of the mechanisms of ageing and, subsequently, help to ameliorate this universal process compromising our quality of life. In this review article, we focus our attention on miRNA targets in conserved pathways involved in organism aging and aging networks, as well as cellular senescence.
