microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding.

miRNAs regulate diverse biological functions, including cell proliferation, apoptosis, senescence, differentiation, metabolism, tumorigenesis, and developments.Mature miRNAs are generated from primary miRNAs (pri-miRNAs) by two RNase III … MicroRNAs (miRNAs) are small noncoding RNAs that are 18-25 nucleotides in length and negatively regulate gene expression by translational repression or mRNA degradation. Previous evidence has demonstrated that miRNAs facilitate tumor growth, migration, invasion, and angiogenesis as well as cell survival and immune evasion by targeting mRNAs [ 9 , 10 ].

The section on miR-155 seems too long for this general page on microRNAs. I would suggest that this material is moved to a new page specific for that microRNA. It is probably worth noting that miR-155 is the first one to be knocked out, but perhaps not much more than that. Alexbateman 13:29, 14 May 2007 (UTC) Viral microRNAs

They do so by binding to a specific location on mRNA, preventing the molecule from being translated. MicroRNAs have also been linked to the development of some types of cancers and a particular chromosome mutation called a translocation. MicroRNAs with altered expression patterns have been found to have oncogenic (oncomirs) or tumor-suppressing (anti-oncomirs) functions present in the pathogenesis of most malignancies.

A growing field of gene expression analysis is in the area of microRNAs (miRNAs), short RNA molecules that also act as eukaryotic post-transcriptional regulators and gene silencing agents. Se hela listan på academic.oup.com microRNAs (1) and that the pattern of miRNA expression is often perturbed in disease states (2–4). Bioinformatic approaches (1) further suggested that the mammalian miRNA repertoire might collectively regulate several thousand genes, even though only a handful of these predicted targets have been validated to date. A small percentage of microRNAs are modified with untemplated nucleotides, usually A or U, added to their 3’ end or “tail”. “Tailing” can modify the microRNA function and in some cases it can act as a molecular switch resulting in developmental and pathological transitions. Background.
