Molecular Oncology, EarlyView.Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Extraction of Small RNA and qPCR Validation of miRNAs in Vigna mungo
Bio-Protocol, 2015 Small RNAs like microRNAs (miRNAs), small interfering RNAs (siRNAs) and other noncoding RNAs including snRNA and snoRNA have tremendous impact on eukaryotic gene regulation.

Small RNA retunes photosynthesis [PDF]
Science, 2017 Plant Science When iron is limited, photosynthetic pathways are remodeled to accommodate the deficit. Iron transport systems and alternative redox carriers are mobilized. Georg et al. now show that a 68-nucleotide small RNA named iron-stress-activated RNA1 (IsaR1) is central to this accommodation in the cyanobacterium Synechocystis . IsaR1 is conserved

Molecular Oncology, EarlyView.Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

A 212-nt long RNA structure in the Tobacco necrosis virus-D RNA genome is resistant to Xrn degradation [PDF]
, 2019 Plus-strand RNA viruses can accumulate viral RNA degradation products during infections. Some of these decay intermediates are generated by the cytosolic 5′-to-3′ exoribonuclease Xrn1 (mammals and yeast) or Xrn4 (plants) and are formed when the enzyme ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A High Resolution Short Interfering RNA (siRNA) Detection Method from Virus-infected Plants
Bio-Protocol, 2013 Plant viruses are strong inducers as well as targets of RNA silencing. In plants RNA silencing acts as a natural defense mechanism against viral infection and is associated with accumulation of virus-specific small interfering RNAs (siRNAs).

Molecular Oncology, EarlyView.In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Molecular Oncology, EarlyView.Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...
