Although they escaped notice until relatively recently, miRNAs comprise one of the more abundant classes of gene regu … microRNAs (miRNAs) are small noncoding RNAs that play important roles in posttranscriptional gene regulation. In animal cells, miRNAs regulate their targets by translational inhibition and mRNA destabilization. Here, we review recent work in animal models that provide insight into the diverse roles of miRNAs in vivo. miRNA is a small non-coding RNA molecule that functions in RNA silencing and post-transcriptional control of gene expression present in plants, animals, and some viruses. Typically, it is 21-22 nucleotides long.

MikroRNA eller miRNA är korta, enkelsträngande RNA-molekyler med en längd på 18–25 nukleotider (i genomsnitt 22). De utgör en form av icke-kodande RNA, vilket innebär att de inte kodar för proteiner. MicroRNA: function, detection, and bioanalysis 2019-01-01 · MicroRNAs (miRNAs) are small non-coding RNAs that repress the translation and reduce the stability of target mRNAs in animal cells. Post-transcriptional regulation mediated by miRNAs is a highly conserved mechanism utilized by organisms throughout phylogeny to fine tune gene expression. 2018-08-14 · Since their serendipitous discovery in nematodes, microRNAs (miRNAs) have emerged as key regulators of biological processes in animals.

MicroRNAs (miRNAs) are endogenous approximately 22 nt RNAs that can play important regulatory roles in animals and plants by targeting mRNAs for cleavage or translational repression.
