Abstract:microRNA (miRNA) genes transcribed by RNA polymerase II generate small noncoding miRNAs of 18 to 24 nucleotides after maturation process. The mature miRNAs and their associated isomirs specifically bind to different mRNA transcripts, resulting in down regulation of multiple genes within the cell in a highly multiplexed way. miRNA expression profiles differ between human cell types suggesting cell-specific impacts of each miRNA on the regulation of different biological processes. Comparison of miRNA profiles of… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
