Noncoding RNAs: The Missing “Linc” in p53-Mediated Repression

Noncoding RNAs: The Missing “Linc” in p53-Mediated Repression

The tumor suppressor protein p53 coordinates the cellular response to stress through regulation of gene expression. Now, Huarte et al. (2010) identify a long intergenic noncoding RNA as a new player in p53-mediated repression of genes involved in apoptosis.

A new 'Linc' between noncoding RNAs and blood development.

Long noncoding RNAs (lncRNAs) are a large and diverse class of functional RNAs that regulate important biological processes, including cell division, survival, and differentiation. In this issue of Genes & Development, Hu and colleagues (2573-2578) report the discovery of LincRNA erythroid prosurvival (LincRNA-EPS), a murine lncRNA that facilitates red blood cell formation (erythropoiesis) by s...

Noncoding RNAs: 'our turn' to join the p53 network.

noncoding rnas and cancer

the eukaryotic complexity involves the expression and regulation of genes via rna-dna, rna-rna, dna-protein and rna-protein interactions. recently, the role of rna molecules in the regulation of genes in higher organisms has become more evident, especially with the discovery that about 97% of the transcriptional output in higher organisms are represented as noncoding rnas: rrna, snornas, trna, ...

A Large Intergenic Noncoding RNA Induced by p53 Mediates Global Gene Repression in the p53 Response

Recently, more than 1000 large intergenic noncoding RNAs (lincRNAs) have been reported. These RNAs are evolutionarily conserved in mammalian genomes and thus presumably function in diverse biological processes. Here, we report the identification of lincRNAs that are regulated by p53. One of these lincRNAs (lincRNA-p21) serves as a repressor in p53-dependent transcriptional responses. Inhibition...
