N 6-methyladenosine RNA modification suppresses antiviral innate sensing pathways via reshaping double-stranded RNA

Nature Communications, 2021
N6-methyladenosine (m6A) RNA modification regulates RNA metabolism, and has been implicated in immune regulation. Here, the authors show that the m6A methyltransferase, METTL3, translocates into the cytoplasm to increase viral RNA m6A modification ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

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.

Activation of influenza virus RNA polymerase by the 5' and 3' terminal duplex of genomic RNA [PDF]

, 2003
The current model for influenza virus mRNA transcription involves the sequential interaction of the viral polymerase with the 5'- and 3'-ends of vRNA, with each RNA-protein interaction triggering a polymerase function necessary for cap-primed ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Binding of small interfering RNA molecules is crucial for RNA interference suppressor activity of rice hoja blanca virus NS3 in plants [PDF]

, 2009
The NS3 protein of rice hoja blanca tenuivirus represents a viral suppressor of RNAi that sequesters small interfering (si)RNAs in vitro. To determine whether this siRNA binding property is the critical determinant for the suppressor activity of NS3, an ...

Viral and cellular messenger RNA targets of viral microRNAs [PDF]

Nature, 2009
Given the propensity of viruses to co-opt cellular pathways and activities for their benefit, it is perhaps not surprising that several viruses have now been shown to reshape the cellular environment by reprogramming the host's RNA-interference machinery. In particular, microRNAs are produced by the various members of the herpesvirus family during both

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular 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 ...

Definition of the minimal viral components required for the initiation of unprimed RNA synthesis by influenza virus RNA polymerase [PDF]

, 2002
The first 11 nt at the 5' end of influenza virus genomic RNA were shown to be both necessary and sufficient for specific binding by the influenza virus polymerase.

The Barley stripe mosaic virus γb protein promotes chloroplast-targeted replication by enhancing unwinding of RNA duplexes.

PLoS Pathogens, 2017
RNA viruses encode various RNA binding proteins that function in many steps of viral infection cycles. These proteins function as RNA helicases, methyltransferases, RNA-dependent RNA polymerases, RNA silencing suppressors, RNA chaperones, movement ...

Genetic recombination in plant-infecting messenger-sense RNA viruses: overview and research perspectives

Frontiers in Plant Science, 2013
RNA recombination is one of the driving forces of genetic variability in (+)-strand RNA viruses. Various types of RNA-RNA crossovers were described including crosses between the same or different viral RNAs or between viral and cellular RNAs.
