Noncoding RNAs and Gene Silencing [PDF]

open access: yesCell, 2007
Noncoding RNA has long been proposed to control gene expression via sequence-specific interactions with regulatory regions. Here, we review the role of noncoding RNA in heterochromatic silencing and in the silencing of transposable elements (TEs), unpaired DNA in meiosis, and developmentally excised DNA.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

open access: yesMolecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

DICER-LIKE2 plays a primary role in transitive silencing of transgenes in Arabidopsis.

open access: yesPLoS ONE, 2008
Dicer-like (DCL) enzymes play a pivotal role in RNA silencing in plants, processing the long double-stranded RNA (dsRNA) that triggers silencing into the primary short interfering RNAs (siRNAs) that mediate it.

Regulation of heterochromatic RNA decay via heterochromatin protein 1 (HP1) [PDF]

open access: yes, 2012
The central dogma of molecular biology describes the directional flow of biological information from DNA via RNA to protein. Information stored in DNA is copied to an mRNA molecule during the process of transcription.

E2A selectively regulates TGF‐β–induced apoptosis in KRAS‐mutant non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Ability to induce apoptosis by TGF‐β is frequently lost in advanced lung adenocarcinoma despite intact TGF‐β signaling. We identify E2A as a mutant KRAS–dependent mediator of resistance to TGF‐β–induced apoptosis. TGF‐β induces E2A via SMAD3 in mutant KRAS cells, and E2A silencing restores apoptosis and enhances radiation response in cell lines ...

RNA interference, growth and differentiation appear normal in African trypanosomes lacking Tudor staphylococcal nuclease. [PDF]

open access: yes, 2010
Ribonucleases play important roles in the RNA interference (RNAi) pathway. The Dicer endonuclease converts double-stranded (ds)RNA into small interfering (si)RNA and the Slicer endonuclease, as a component of the RNA induced silencing complex (RISC ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

RNA-Spray-Mediated Silencing of Fusarium graminearum AGO and DCL Genes Improve Barley Disease Resistance

open access: yesFrontiers in Plant Science, 2020
Over the last decade, several studies have revealed the enormous potential of RNA-silencing strategies as a potential alternative to conventional pesticides for plant protection.

Splayed : a chromatin remodeler regulating tissue specific gene silencing and developmental timing [PDF]

open access: yes, 2014
A number of mechanisms that contribute to epigenetic regulation of gene expression have been described in plants. The concert actions of these mechanisms contribute to proper patterning of gene expression within organs and tissues, therefore insuring ...

Adaptor protein CIN85 potentiates the motility of osteosarcoma cells via the Akt/mTOR and MMP2‐COL3A1 axis

open access: yesMolecular Oncology, EarlyView.
CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting
