Preventing transcriptional gene silencing by active DNA demethylation [PDF]
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

Diverging affinity of tospovirus RNA silencing suppressor proteins, NSs, for various RNA duplex molecules [PDF]
The tospovirus NSs protein was previously shown to suppress the antiviral RNA silencing mechanism in plants. Here the biochemical analysis of NSs proteins from different tospoviruses, using purified NSs or NSs containing cell extracts, is described.

Transcriptional control and gene silencing inPlasmodium falciparum
Infection with the apicomplexan parasite Plasmodium falciparum is associated with a high burden of morbidity and mortality across the developing world, yet the mechanisms of transcriptional control in this organism are poorly understood. While P. falciparum possesses many of the characteristics common to eukaryotic transcription, including much of the ...

Function of the upstream activating factor in chromatin structure organization and transcriptional regulation at the yeast ribosomal DNA [PDF]
Chromatin is the template of all processes involved in DNA metabolism in the eukaryotic cell. Accordingly, chromatin is a dynamic structure which changes in its composition and posttranslational modification correlating with the functional state of a ...

Antiviral innate immune response of RNA interference
RNA interference (RNAi) is an ancient, natural process conserved among species from different kingdoms. RNAi is a transcriptional and post-transcriptional gene silencing mechanism in which, double-stranded RNA or hairpin RNA is cleaved by an RNase III ...

Role of RNA Interference (RNAi) in the Moss Physcomitrella patens [PDF]
RNA interference (RNAi) is a mechanism that regulates genes by either transcriptional (TGS) or posttranscriptional gene silencing (PTGS), required for genome maintenance and proper development of an organism.

Rhodopsin targeted transcriptional silencing by DNA-binding
Transcription factors (TFs) operate by the combined activity of their DNA-binding domains (DBDs) and effector domains (EDs) enabling the coordination of gene expression on a genomic scale.

Gene silencing: Fleshing out the bones [PDF]
Genetic studies are revealing the pathway for RNA-mediated gene silencing. Short RNA molecules are the key, giving sequence specificity for RNA degradation and mediating communication within and between cells; these short RNAs are common to ...

RNA-induced epigenetic silencing inhibits HIV-1 reactivation from latency
Background Current antiretroviral therapy is effective in controlling HIV-1 infection. However, cessation of therapy is associated with rapid return of viremia from the viral reservoir.
