Biomolecular Concepts, 2014 Recent discoveries in eukaryotes have shown that autophagy-mediated degradation of DICER and ARGONAUTE (AGO), the proteins involved in post-transcriptional gene silencing (PTGS), can occur in response to viral infection and starvation.

Toward a molecular understanding of yeast silent chromatin : roles for H4K16 acetylation and the Sir3 C-terminus [PDF]
, 2012 Discrete regions of the eukaryotic genome assume a heritable chromatin structure that is refractory to gene expression. In budding yeast, silent chromatin is characterized by the loading of the Silent Information Regulatory (Sir) proteins (Sir2, Sir3 and

Enhancement of post-transcriptional gene silencing by grafting [PDF]
Plant Signaling & Behavior, 2008 We showed previously that grafting transmitted silencing occurred when transgenic ACC oxidase 1 (ACO1) overexpressing tomato plants that also produced siRNAs were grafted onto transgenic stocks that already showed strong silencing. The presence of siRNAs in these overexpressing scions may indicate that silencing, though inefficient, may already occur ...

A New Gene Therapy Approach for Cardiovascular Disease by Non-coding RNAs Acting in the Nucleus
Molecular Therapy: Nucleic Acids, 2014 This review discusses recent developments in the use of non-coding RNAs (ncRNAs) for the regulation of therapeutically relevant genes, with special focus on applications for the treatment of cardiovascular diseases.

Preventing transcriptional gene silencing by active DNA demethylation [PDF]
FEBS Letters, 2005 DNA methylation is important for stable transcriptional gene silencing. DNA methyltransferases for de novo as well as maintenance methylation have been well characterized. However, enzymes responsible for active DNA demethylation have been elusive and several reported mechanisms of active demethylation have been controversial. There has been a critical

CRP-cAMP mediates silencing of Salmonella virulence at the post-transcriptional level [PDF]
, 2018 Invasion of epithelial cells by Salmonella enterica requires expression of genes located in the pathogenicity island I (SPI-1). The expression of SPI-1 genes is very tightly regulated and activated only under specific conditions.

An enhanced CRISPR repressor for targeted mammalian gene regulation. [PDF]
, 2018 The RNA-guided endonuclease Cas9 can be converted into a programmable transcriptional repressor, but inefficiencies in target-gene silencing have limited its utility.
