Viruses and the cellular RNA decay machinery. [PDF]
The ability to control cellular and viral gene expression, either globally or selectively, is central to a successful viral infection, and it is also crucial for the host to respond and eradicate pathogens.

UPFront and center in RNA decay: UPF1 in nonsense-mediated mRNA decay and beyond
Nonsense-mediated mRNA decay (NMD), which is arguably the best-characterized translation-dependent regulatory pathway in mammals, selectively degrades mRNAs as a means of post-transcriptional gene control.

Identification of a novel human E-Cadherin splice variant andassessment of its effects upon EMT-related events [PDF]
Epithelial Cadherin (E-cadherin) is involved in calcium-dependent cell-cell adhesion and signal transduction. The E-cadherin decrease/loss is a hallmark of Epithelial to Mesenchymal Transition (EMT), a key event in tumor progression.

Nonsense-mediated mRNA decay in the ADAMTS13 gene caused by a 29-nucleotide deletion
Background In mammalian cells a regulatory mechanism, known as nonsense-mediated mRNA decay, degrades mRNA harboring premature termination codons. This mechanism is intron-dependent and functions as a quality control mechanism to eliminate abnormal ...

Suppressing nonsense--a surprising function for 5-azacytidine. [PDF]
In this issue of EMBO Molecular Medicine, Bhuvanagiri et al report on a chemical means to convert molecular junk into gold. They identify a chemical inhibitor of a quality control pathway that is best known for its ability to clear cells of rubbish, but ...

When a ribosome encounters a premature termination codon [PDF]
In mammalian cells, aberrant transcripts harboring a prematuretermination codon (PTC) can be generated by abnormal orinefficient biogenesis of mRNAs or by somatic mutation.Truncated polypeptides synthesized from these aberranttranscripts could be toxic ...

MicroRNA-mediated repression of nonsense mRNAs
Numerous studies have established important roles for microRNAs (miRNAs) in regulating gene expression. Here, we report that miRNAs also serve as a surveillance system to repress the expression of nonsense mRNAs that may produce harmful truncated ...

Nonsense-mediated mRNA decay factor UPF1 promotes aggresome formation
Nonsense-mediated mRNA decay (NMD) is a translation-coupled process that eliminates mRNAs containing premature translation-termination codons. Here the authors identify a role for the NMD factor UPF1 in protein quality control, whereby truncated ...

A system for coordinated analysis of translational readthrough and nonsense-mediated mRNA decay. [PDF]
The nonsense-mediated mRNA decay (NMD) pathway degrades mRNAs containing premature termination codons, limiting the expression of potentially deleterious truncated proteins.

Aberrant mRNA transcripts and nonsense-mediated decay [PDF]
Nobody's perfect, and even the cell turns out a certain fraction of erroneous mRNA transcripts. One of the key quality control mechanisms put in place to recognize and eliminate these transcripts before they can be translated into faulty proteins is nonsense-mediated decay.
