MicroRNAs: Loquacious Speaks out [PDF]

, 2005
In Drosophila, Dicer-2 requires the double-stranded RNA binding protein R2D2, to mediate the assembly of short interfering RNAs into the RNA-induced silencing complex.

Unraveling LINE‐1 retrotransposition in head and neck squamous cell carcinoma

Molecular Oncology, EarlyView.
The novel RetroTest method allows the detection of L1 activation in clinical samples with low DNA input, providing global L1 activity and the identification of the L1 source element. We applied RetroTest to a real‐world cohort of HNSCC patients where we reported an early L1 activation, with more than 60% of T1 patients showing L1 activity.

The rough endoplasmatic reticulum is a central nucleation site of siRNA-mediated RNA silencing

EMBO Journal, 2013
Despite progress in mechanistic understanding of the RNA interference (RNAi) pathways, the subcellular sites of RNA silencing remain under debate. Here we show that loading of lipid‐transfected siRNAs and endogenous microRNAs (miRNA) into RISC (RNA ...

Simultaneous inhibition of TRIM24 and TRIM28 sensitises prostate cancer cells to antiandrogen therapy, decreasing VEGF signalling and angiogenesis

Molecular Oncology, EarlyView.
TRIM24 and TRIM28 are androgen receptor (AR) coregulators which exhibit increased expression with cancer progression. Both TRIM24 and TRIM28 combine to influence the response of castrate‐resistant prostate cancer (CRPC) cells to AR inhibitors by mediating AR signalling, regulation of MYC and upregulating VEGF to promote angiogenesis. Castrate‐resistant

Plant RNA Regulatory Network and RNA Granules in Virus Infection

Frontiers in Plant Science, 2017
Regulation of post-transcriptional gene expression on mRNA level in eukaryotic cells includes translocation, translation, translational repression, storage, mRNA decay, RNA silencing, and nonsense-mediated decay.

Human tRNA-derived small RNAs in the global regulation of RNA silencing.

RNA: A publication of the RNA Society, 2010
Competition between mammalian RNAi-related gene silencing pathways is well documented. It is therefore important to identify all classes of small RNAs to determine their relationship with RNAi and how they affect each other functionally.

Tumor clusters with divergent inflammation and human retroelement expression determine the clinical outcome of patients with serous ovarian cancer

Molecular Oncology, EarlyView.
Analysis of treatment‐naïve high‐grade serous ovarian carcinoma (HGSOC) and control tissues for ERVs, LINE‐1 (L1), inflammation, and immune checkpoints identified five clusters with diverse patient recurrence‐free survivals. An inflammation score was calculated and correlated with retroelement expression, where one novel cluster (Triple‐I) with high ...

Virus Recovery Is Induced in Brome mosaic virus p2 Transgenic Plants Showing Synchronous Complementation and RNA-2-Specific Silencing

Molecular Plant-Microbe Interactions, 2000
Nicotiana benthamiana plants expressing Brome mosaic virus (BMV) p2 protein complemented replication of RNAs1+3 but, surprisingly, supported little or no replication of RNA-2. Despite this, the p2 transgenic plants were able to support systemic migration

Effect of Non-Coding RNA on Post-Transcriptional Gene Silencing of Alzheimer Disease [PDF]

, 2010
A large amount of hidden biological information is contained in the human genome, which is not expressed or revealed in the form of proteins; the usual end product form of gene expression.

Identification and RNA Binding Characterization of Plant Virus RNA Silencing Suppressor Proteins

, 2013
Suppression is a common mechanism employed by viruses to evade the antiviral effects of the host’s RNA silencing pathway. The activity of suppression has commonly been localized to gene products in the virus, but the variety of mechanisms used in ...
