WebDec 24, 2010 · When 1 ng each of synthetic vRNA, cRNA and mRNA was used as a template for reverse transcription with a primer for vRNA, substantial background amplification of cRNA (3% of vRNA) and mRNA (5% of vRNA) was observed. With primers for cRNA, more vRNA than cRNA and substantial amounts of mRNA (25% of cRNA) … WebJan 16, 2024 · Here, we find that influenza polymerase requires ANP32 proteins to support both steps of genome replication: cRNA and vRNA synthesis. However, avian strains are only restricted in vRNA synthesis in human cells. Therefore, avian influenza polymerase can use human ANP32 orthologues to support cRNA synthesis, without acquiring …

WebRNA species include vRNA, cRNA, and mRNA. Primers and reference numbers used in subsequent experiments are depicted. Primers used in RT are as follows: RT1 represents oligo-dT and RT2 is specific to the noncoding region of NS cRNA. (B) RT-PCR products of NEP/NS2 mRNA and NS1 mRNA/3′ NS cRNA. RT1 and RT2 depict primers used in the … WebDec 15, 2024 · Figure 1. Mutations at the M segment-specific non-coding nucleotides of the influenza A vRNA and cRNA promoters. Mutations at the X 14′ and Y 13 nucleotides of the vRNA promoter were introduced by site-directed mutagenesis, named vX 14′ Y 13 or vXY (left, black). Position 1′ means the starting point of the 5′ UTR, while position 1 does …
WebThe NF-κB signaling pathway has previously been shown to be required for efficient influenza A virus replication, although the molecular mechanism is not well understood. In this study, we identified a specific step of the influenza virus life cycle WebFeb 19, 2003 · RNA interference (RNAi) is a process by which double-stranded RNA (dsRNA) directs sequence-specific degradation of messenger RNA (mRNA) (10–12). This phenomenon was initially observed in Caenorhabditis elegans(13), in plants (10, 14), and, recently, in mammalian cells (15). In plants, it is an evolutionarily conserved response to …

WebJul 16, 2024 · Moreover, vRNA levels of segment 4, 5 and 6 were significantly increased by NS1 in the infected cells (Fig. 2f). However, the levels of vRNA and protein do not necessarily correlate, suggesting viral promoter-specific regulation of the synthesis of mRNA and vRNA, and translational regulation [18, 20, 21, 38, 39]. Thus, the mechanism of …
WebApr 1, 2013 · Three RNA forms (vRNA, cRNA, mRNA) produced from the reporter gene during influenza infection. EGFP, enhanced green fluorescent protein; Luc, luciferase; RdRp, influenza RNA-dependent RNA polymerase. The objectives of the present study were to compare influenza reporters using vRNA or cRNA promoters.
