Influenza Virus Exploits an Interferon-Independent lncRNA to Preserve Viral RNA Synthesis through Stabilizing Viral RNA Polymerase PB1

Cell Reports, 2019
Summary: Long noncoding RNAs (lncRNAs) participate in host antiviral defense by modulating immune responses. However, it remains largely unexplored how viruses exploit interferon (IFN)-independent host lncRNAs to facilitate viral replication.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

Molecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Mycoviruses, RNA Silencing, and Viral RNA Recombination [PDF]

, 2011
In contrast to viruses of plants and animals, viruses of fungi, mycoviruses, uniformly lack an extracellular phase to their replication cycle. The persistent, intracellular nature of the mycovirus life cycle presents technical challenges to experimental design. However, these properties, coupled with the relative simplicity and evolutionary position of

LGP2 plays a critical role in sensitizing mda-5 to activation by double-stranded RNA. [PDF]

, 2013
The DExD/H box RNA helicases retinoic acid-inducible gene-I (RIG-I) and melanoma differentiation associated gene-5 (mda-5) sense viral RNA in the cytoplasm of infected cells and activate signal transduction pathways that trigger the production of type I ...

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.

Ribosomal frameshifting on viral RNAs

Journal of General Virology, 1995
Introduction. Accurate maintenance of the translational reading frame by ribosomes is essential for the production of functional proteins and unsurprisingly, errors in frame maintenance have been estimated to occur at rates probably lower than 5 × 10-5 per codon (Kurland, 1992).

IN VITRO SYNTHESIS OF VIRAL RNA BY THE POLIOVIRUS RNA POLYMERASE [PDF]

Proceedings of the National Academy of Sciences, 1964
Infection of cultured mammalian cells by either Mengovirus or poliovirus causes the appearance of a new cytoplasmic RNA polymerase. The enzymes induced by the two viruses are quite similar. Both show a requirement for magnesium ions, are inhibited by manganese ions, require all four nucleoside triphosphates for maximal activity, and catalyze the ...

USP7 inhibits FOXO1 activity in chronic lymphocytic leukaemia cells enhancing cell survival

Molecular Oncology, EarlyView.
CLL cells rely on BCR‐mediated signalling for survival and proliferation in part through suppression of FOXO1. FOXO1 activity is regulated by a plethora of post‐translational modifications including phosphorylation and ubiquitination. We demonstrated that dual inhibition of BCR signalling and the deubiquitinase USP7 activates FOXO1, modulating its ...

Avian Bornaviruses Escape Recognition by the Innate Immune System [PDF]

, 2010
Like other pathogens that readily persist in animal hosts, members of the Bornaviridae family have evolved effective mechanisms to evade the innate immune response.

Overcoming platinum resistance by the disulfiram metabolite CuET in novel preclinical models of human carcinomas

Molecular Oncology, EarlyView.
Cisplatin‐resistant cancer cells survive DNA‐damaging platinum‐based treatment yet remain sensitive to CuET‐induced proteotoxic stress. The distinct mechanism of action allows CuET to overcome and eliminate cisplatin‐resistant tumour cells, unless highly expressed metallothioneins (MTs) interfere with CuET, thereby highlighting MT levels as candidate ...
