Size Selective Recognition of siRNA by an RNA Silencing Suppressor [PDF]

open access: yesCell, 2003
RNA silencing in plants likely exists as a defense mechanism against molecular parasites such as RNA viruses, retrotransposons, and transgenes. As a result, many plant viruses have adapted mechanisms to evade and suppress gene silencing. Tombusviruses express a 19 kDa protein (p19), which has been shown to suppress RNA silencing in vivo and bind ...

The p122 subunit of Tobacco mosaic virus replicase is a potent silencing suppressor and compromises both siRNA and miRNA mediated pathways

open access: yes, 2007
One of the functions of RNA silencing in plants is to defend against molecular parasites, such as viruses, retrotransposons, and transgenes. Plant viruses are inducers, as well as targets, of RNA silencing-based antiviral defense.

Enhanced transgene expression in sugarcane by co-expression of virus-encoded RNA silencing suppressors.

open access: yesPLoS ONE, 2013
Post-transcriptional gene silencing is commonly observed in polyploid species and often poses a major limitation to plant improvement via biotechnology.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Type I interferons modulate autophagy to shape gemcitabine response in pancreatic cancer cells

open access: yesFEBS Open Bio, EarlyView.
Type I interferons differentially modulate autophagy and the response of pancreatic cancer cells to gemcitabine. IFNα2b stimulates autophagic flux and protects cells from gemcitabine‐induced cell death, contributing to chemoresistance. In contrast, IFNβ1a inhibits autophagosome formation and enhances gemcitabine‐induced cell death, resulting in ...

RASSF10 is an epigenetically silenced tumor suppressor in gastric cancer

open access: yesOncology Reports, 2014
To better understand the role of the N-Terminal Ras association domain family (RASSF) genes in the development of gastric cancer, we examined the expression of RASSF7 and RASSF10 and RASSF10 methylation in gastric cancer. We found that RASSF10 expression was lost in six gastric cancer cell lines, and was rescued by a DNA demethylating agent and a ...

Screening and Identification of Virus-Encoded RNA Silencing Suppressors [PDF]

open access: yes, 2008
RNA silencing, including RNA interference, is a novel method of gene regulation and one of the potent host-defense mechanisms against the viruses. In the course of evolution, the viruses have encoded proteins with the potential to suppress the host RNA silencing mechanism as a counterdefense strategy.

The Benyvirus RNA Silencing Suppressor Is Essential for Long-Distance Movement, Requires Both Zinc-Finger and NoLS Basic Residues but Not a Nucleolar Localization for Its Silencing-Suppression Activity

open access: yesMolecular Plant-Microbe Interactions, 2013
The RNA silencing-suppression properties of Beet necrotic yellow vein virus (BNYVV) and Beet soil-borne mosaic virus (BSBMV) cysteine-rich p14 proteins have been investigated.

Dactolisib outperforms Rapamycin in potentiating apoptosis induced by XPO1, Bcl‐2 and Mcl‐1 blockade in preclinical glioblastoma models

open access: yesFEBS Open Bio, EarlyView.
The PAM pathway and its impact on cellular metabolism. Color‐coded key symbols represent Rapamycin (R, orange, targeting mTOR) and Dactolisib (D, green, targeting PI3K/mTOR), indicating their sites of action. Created with BioRenders.com. Glioblastoma resists therapy through interconnected survival programs.

GBS‐MeDIP: A method for the simultaneous identification of genetic and epigenetic variants in tumors

open access: yesFEBS Open Bio, EarlyView.
GBS‐MeDIP combines DNA sequencing with enrichment of methylated DNA to profile genetic and epigenetic variation in the same reduced genomic fraction. Applied to gastric cancer and parathyroid tumors, it identifies sequence variants, copy number changes, and differentially methylated regions together, helping distinguish true epigenetic changes from ...
