Circadian Control of Messenger RNA Stability. Association with a Sequence-Specific Messenger RNA Decay Pathway

Circadian control of messenger RNA stability. Association with a sequence-specific messenger RNA decay pathway.

Transcriptional and posttranscriptional regulation are well-established mechanisms for circadian gene expression. Among the latter, differential messenger RNA (mRNA) stability has been hypothesized to control gene expression in response to the clock. However, direct proof that the rate of mRNA turnover can be regulated by the clock is lacking. Previous microarray expression data for unstable mR...

ACTH Action on Messenger RNA Stability Mechanisms

The regulation of mRNA stability has emerged as a critical control step in dynamic gene expression. This process occurs in response to modifications of the cellular environment, including hormonal variations, and regulates the expression of subsets of proteins whose levels need to be rapidly adjusted. Modulation of messenger RNA stability is usually mediated by stabilizing or destabilizing RNA-...

Interference of nonsense mutations with eukaryotic messenger RNA stability.

The fine structure map of the yeast URA 3 gene was established by meiotic recombination, and amber nonsense mutations were located at different points on the map. The effect of the length of the labeling time on the specific radioactivity of ura 3 messenger RNA and on its repartition between poly(A)-RNA and RNA not containing poly(A) has been followed in nonsense mutants. Nonsense mutations red...

Who discovered messenger RNA?

The announcement of the discovery of messenger RNA (mRNA) and the cracking of the genetic code took place within weeks of each other in a climax of scientific excitement during the summer of 1961. Although mRNA is of decisive importance to our understanding of gene function, no Nobel Prize was awarded for its discovery. The large number of people involved, the complex nature of the results, and...
