AGO6 functions in RNA-mediated transcriptional gene silencing in shoot and root meristems in Arabidopsis thaliana. [PDF]
PLoS ONE, 2011 RNA-directed DNA methylation (RdDM) is a small interfering RNA (siRNA)-mediated epigenetic modification that contributes to transposon silencing in plants. RdDM requires a complex transcriptional machinery that includes specialized RNA polymerases, named

BNYVV-derived dsRNA confers resistance to rhizomania disease of sugar beet as evidenced by a novel transgenic hairy root approach [PDF]
, 2010 Agrobacterium rhizogenes-transformed sugar beet hairy roots, expressing dsRNA from the Beet necrotic yellow vein virus replicase gene, were used as a novel approach to assess the efficacy of three intron-hairpin constructs at conferring resistance to ...

Transcriptional silencing of multiple genes in trophozoites of Entamoeba histolytica. [PDF]
PLoS Pathogens, 2006 In a previous work we described the transcriptional silencing of the amoebapore A (AP-A) gene (Ehap-a) of Entamoeba histolytica strain HM-1:IMSS. The silencing occurred following transfection with a plasmid containing a 5' upstream region (473 bp) of ...

The post-transcriptional gene silencing pathway in Eucalyptus
Genetics and Molecular Biology, 2005 Post-transcriptional gene silencing (PTGS) is a conserved surveillance mechanism that identifies and cleaves double-stranded RNA molecules and their cellular cognate transcripts.

Trithorax group proteins: switching genes on and keeping them active [PDF]
, 2011 Cellular memory is provided by two counteracting groups of chromatin proteins termed Trithorax group (TrxG) and Polycomb group (PcG) proteins. TrxG proteins activate transcription and are perhaps best known because of the involvement of the TrxG protein ...

Epigenetic transcriptional gene silencing in Entamoeba histolytica [PDF]
IUBMB Life, 2008 AbstractThe human intestinal pathogen Entamoeba histolytica has a number of virulence factors which can cause damage to the host. Transcriptional silencing of the gene coding for one of its major toxic molecules, the amoebapore (Ehap‐a), occurred following the transfection of amoebic trophozoites with a plasmid containing the 5′ promoter region of Ehap‐

Emerging connections between small RNAs and phytohormones [PDF]
, 2020 Small RNAs (sRNAs), mainly including miRNAs and siRNAs, are ubiquitous in eukaryotes. sRNAs mostly negatively regulate gene expression via (post-)transcriptional gene silencing through DNA methylation, mRNA cleavage, or translation inhibition.

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
