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 ...

RNA elements directing in vivo assembly of the 7SK/MePCE/Larp7 transcriptional regulatory snRNP [PDF]

, 2013
Through controlling the nuclear level of active positive transcription elongation factor b (P-TEFb), the 7SK small nuclear RNA (snRNA) functions as a key regulator of RNA polymerase II transcription.

Stimulator of interferon genes agonist augmented antitumor immunity of osimertinib in Egfr‐mutated lung cancer

Molecular Oncology, EarlyView.
Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.

Interstitial Contacts in an RNA-Dependent RNA Polymerase Lattice [PDF]

Journal of Molecular Biology, 2011
Catalytic activities can be facilitated by ordered enzymatic arrays that co-localize and orient enzymes and their substrates. The purified RNA-dependent RNA polymerase from poliovirus self-assembles to form two-dimensional lattices, possibly facilitating the assembly of viral RNA replication complexes on the cytoplasmic face of intracellular membranes.

A twist in the tail : SHAPE mapping of long-range interactions and structural rearrangements of RNA elements involved in HCV replication [PDF]

, 2011
The RNA structure and long-range interactions of the SL9266 cis-acting replication element located within the NS5B coding region of hepatitis C virus (HCV) were determined using selective 2′-hydroxyl acylation analysed by primer extension.

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Antiviral Effects of a Transgenic RNA-Dependent RNA Polymerase [PDF]

Journal of Virology, 2011
ABSTRACTTransgenic expression of the RNA-dependent RNA polymerase 3Dpolinhibited infection of Theiler's murine encephalitis virus (TMEV), a picornavirus from which it was derived. Here, we infected 3Dpoltransgenic mice with another picornavirus, as well as an alphaherpesvirus and a rhabdovirus.

Distinct roles of non-canonical poly(A) polymerases in RNA metabolism [PDF]

, 2009
Trf4p and Trf5p are non-canonical poly(A) polymerases and are part of the heteromeric protein complexes TRAMP4 and TRAMP5 that promote the degradation of aberrant and short-lived RNA substrates by interacting with the nuclear exosome. To assess the level
