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.

Author information: (1)Friedrich Miescher Institute for Biomedical Research, 4002 Basel, Switzerland. ramesh.pillai@fmi.ch MicroRNAs are sequence-specific regulators of post-transcriptional gene expression in many eukaryotes. Discovered in nematodes in 1993, microRNAs (miRNAs) are non-coding RNAs that are related to small interfering RNAs (siRNAs), the small RNAs that guide RNA interference (RNAi). miRNAs sculpt gene expression profiles during plant and animal development. Many targets of plant microRNAs (miRNAs) are thought to play important roles in plant physiology and development.

We document the approaches used to study the function of a single miRNA and miRNA regulation of biological pathways in the sea urchin embryo. miRNAs function in a broad range of biological processes in plants and animals (Kidner and Martienssen,2005; Alvarez-Garcia and Miska,2005). The first insight into their function came from phenotypic studies of mutations that disrupt core components of the miRNA pathway. MicroRNA-7 (miR-7), as a unique member of the miRNAs family, has a high degree of conserved mature sequences with a length of 21–23 nt in different species (Fig. 1).In humans, three genes, including miR-7-1, miR-7-2 and miR-7-3 located on different chromosomes, respectively encode the corresponding precursor sequence which is processed and sheared into the same mature miR-7 sequence []. This decision is partly mediated by miRNA functions, in particular by modulating the amount of miRNAs, the amount of mRNA targets, or the activity/mode of action of miRNA-protein complexes. In turn, these changes determine the specificity, timing, and concentration of gene products expressed upon stresses.

Typically, it is 21-22 nucleotides long. microRNA genes are predominately found in intergenic areas. MicroRNAs (miRNAs) are a class of small, endogenous RNAs of 21–25 nucleotides (nts) in length. They play an important regulatory role in animals and plants by targeting specific mRNAs for degradation or translation repression. Since their serendipitous discovery in nematodes, microRNAs (miRNAs) have emerged as key regulators of biological processes in animals.

Functions of miRNAs Tumor suppression and oncogenes- • About 50% of the annotated human miRNAs map within fragile sites of chromosomes, which are 4 Mar 2015 How Do MiRNAs Function? miRNAs function by base-pairing complementary sequences within mRNA molecules, and this results in sequence- In animals, miRNAs are involved in multiple biological functions, including development, apoptosis, metabolism and signaling pathways. miRNA genes are MicroRNA publishers letters full-length research review articles drug clinical trial studies and thematic issues on all aspects of microRNA research.

De term miRNA werd in oktober 2001 voor het eerst geïntroduceerd in een drietal artikelen in het wetenschappelijke tijdschrift Science. Evidence for natural antisense transcript-mediated inhibition of microRNA function. Faghihi MA(1), Zhang M, Huang J, Modarresi F, Van der Brug MP, Nalls MA, Cookson MR, St-Laurent G 3rd, Wahlestedt C. MicroRNAs are small non-coding RNAs of 19–24 nucleotides in length that downregulate gene expression during various crucial cell processes such as apoptosis, differentiation and development. Recent work supports a role for miRNAs in the initiation and progression of human malignancies.

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. microRNA genes are predominately found in intergenic areas. MicroRNAs (miRNAs) are a class of small, endogenous RNAs of 21–25 nucleotides (nts) in length. They play an important regulatory role in animals and plants by targeting specific mRNAs for degradation or translation repression. Since their serendipitous discovery in nematodes, microRNAs (miRNAs) have emerged as key regulators of biological processes in animals.

microRNAs – function & biogenesis microRNAs (miRNAs) are small non-coding RNAs that span between 18-24 nucleotides. MicroRNAs regulate gene expression on a post-transcriptional level through base-pairing with complementary sequences of the 3´untranslated region (UTR) of messenger RNAs (mRNA).
