Virus infection elevates transcriptional activity of miR164a promoter in plants [PDF]

, 2009
Background: Micro RNAs (miRs) constitute a large group of endogenous small RNAs that have crucial roles in many important plant functions. Virus infection and transgenic expression of viral proteins alter accumulation and activity of miRs and so far ...

Aspirin use and survival after the diagnosis of breast cancer:a population-based cohort study [PDF]

, 2014
Background: Aspirin use has been associated with a reduced cancer incidence and fewer deaths from cancer. This study examined whether women with breast cancer prescribed aspirin postdiagnosis had improved survival.Methods:An observational, population ...

Analysis of the Involvement of an Inducible Arabidopsis RNA-Dependent RNA Polymerase in Antiviral Defense

Molecular Plant-Microbe Interactions, 2003
RNA-dependent RNA polymerases (RdRPs) have been implicated in posttranscriptional gene silencing (PTGS) and antiviral defense. An Arabidopsis RdRP (SDE1/SGS2) has been previously shown to be required for transgene-induced PTGS but has no general role in ...

Study of the functional domains of the PTGS suppressor V2 from geminivirus Beet curly top virus (BCTV) [PDF]

, 2019
Geminiviruses constitute a group of plant viruses that infect vegetable crops all over the world. Among the Geminiviridae family, the genera Mastrevirus, Begomovirus and Curtovirus are the most abundant.

Silencing of β-1,3-glucanase genes in tobacco correlates with an increased abundance of RNA degradation intermediates [PDF]

, 1998
Post-transcriptional gene silencing of beta-1,3 glucanase genes in the transgenic tobacco line T17 is characterised by an increased turnover and, as a consequence, reduced levels of gn1 transgene and endogenous beta-1,3 glucanase mRNAs, Here, additional ...

Collective post‐traumatic growth: Validating and measuring positive change in the collective self among victims of sexual violence

Political Psychology, Volume 47, Issue 2, April 2026.
Abstract Across the world, women's personal responses to gender‐based violence are increasingly political. In the current paper, we consider whether positive changes in the collective self, arising from personal experience of gender‐based violence, which may lie at the heart of this phenomenon, can be evidenced.

The convergence of autophagy, small RNA and the stress response – implications for transgenerational epigenetic inheritance in plants

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.

Study of the PTGS suppressor activity of V2 protein from geminivirus Beet curly top virus [PDF]

, 2017
Suppression of gene silencing is a key mechanism for the success of viral infection in plants. DNA viruses from the Geminiviridae family encode several proteins that suppress post- and transcriptional gene silencing (PTGS/TGS). In Begomovirus V2 has been
