MicroRNA and the Heart

MicroRNA and the Heart

MicroRNAs are short noncoding 18-25 nucleotide long RNA which bind and inhibit mRNA. Currently, there are over 1000 known human microRNAs, and microRNAs control over 50% of mammalian protein coding genes. As more is learnt about the regulation and wide reaching function of microRNA, their importance in regulating cell pathways in homeostasis and disease are becoming more apparent.
