2000年3月13日 · We found that NF-κB complexes induced by PKR are composed primarily of p50-p65 heterodimers and also of c-rel-p50 heterodimers. As described for other stimuli, …

Here, we have studied the ability of PKR to activate NF-kappaB in a reporter assay and have shown for the first time that two catalytically inactive PKR mutants, PKR/KR296 and a deletion …

2025年3月24日 · 对NF-кB (p65) 的免疫荧光定位结果显示:在NDV感染过程中, p65进入细胞核; 使用10 mg · mL-1 的2-AP抑制PKR活性后, 部分抑制了p65进入细胞核 , 说明PKR的活性正向调 …

2020年8月15日 · Double-stranded RNA (dsRNA)-dependent protein kinase R (PKR) activation via autophosphorylation is the central cellular response to stress that promotes cell death or …

The double-stranded RNA (dsRNA)-dependent protein kinase PKR activates NF-kappa B via the I kappa B kinase (IKK) complex, but little is known about additional molecules that may be …

Here we show that in response to poly(rI) · poly(rC) (pIC), PKR activates IκB kinase (IKK), leading to the degradation of the inhibitors IκBα and IκBβ and the concomitant release of NF-κB. The …

2018年9月10日 · Double-stranded RNA-dependent kinase (PKR) promotes the activation of NF-κB and the production of pro-inflammatory factors including tumor necrosis factor alpha (TNF …

2001年1月18日 · The double stranded RNA-dependent protein kinase (PKR), in addition to its role as a translational controlling factor, is a key transcriptional regulator exerting antiviral and …

PKR-mediated activation of NF-kB can be inhibited by blocking PKR catalytic activity using the chemical inhibitor 2-aminopurine (Kumar et al., 1994; Cheshire et al., 1999).
