MicroRNAs regulate expression of oncogenes.
Featured Article: Johnson SM, Grosshans H, Shingara J, Byrom M, Jarvis R, Cheng A, Labourier E, et al. RAS is regulated by the let-7 microRNA family. Cell 2005;120:635– 47. Today, we fully appreciate that microRNAs (miRNAs) represent a paradigm shift in our understanding of gene expression and disease, but it was not always this way. miRNAs are small noncoding RNAs belonging to a novel class of...
متن کاملMicroRNAs as oncogenes.
MicroRNAs (miRNAs) are a class of non-coding RNAs that function as endogenous triggers of the RNA interference pathway. Originally discovered in Caenorhabditis elegans, this group of tiny RNAs has moved to the forefront of biology. With over 300 miRNA genes identified in the human genome, and a plethora of predicted mRNA targets, it is believed that these small RNAs have a central role in diver...
متن کاملHow do microRNAs regulate gene expression?
miRNAs (microRNAs) are short non-coding RNAs that regulate gene expression post-transcriptionally. They generally bind to the 3′-UTR (untranslated region) of their target mRNAs and repress protein production by destabilizing the mRNA and translational silencing. The exact mechanism of miRNA-mediated translational repression is yet to be fully determined, but recent data from our laboratory have...
متن کاملHow do microRNAs regulate gene expression?
Several thousand human genes, amounting to about one-third of the whole genome, are potential targets for regulation by the several hundred microRNAs (miRNAs) encoded in the genome. The regulation occurs posttranscriptionally and involves the approximately 21-nucleotide miRNA interacting with a target site in the mRNA that generally has imperfect complementarity to the miRNA. The target sites a...
متن کاملmicroRNAs as oncogenes and tumor suppressors
microRNAs (miRNAs) are a new class of non-protein-coding, endogenous, small RNAs. They are important regulatory molecules in animals and plants. miRNA regulates gene expression by translational repression, mRNA cleavage, and mRNA decay initiated by miRNA-guided rapid deadenylation. Recent studies show that some miRNAs regulate cell proliferation and apoptosis processes that are important in can...
