The findings demonstrated that compound 1 effectively suppressed NO generation, characterized by an IC50 of 233 ± 17 µM. This suggests a potential role for this compound as an anti-inflammatory agent. 1 effectively inhibited, in a dose-dependent manner, the release of the inflammatory ...
NF-κB signalling is a key element in cancer, mainly related to the activity of IKKβ. IKKα kinase also participates in this process by mechanisms that are primarily unknown. Methods: We generated a compound mouse model with mutation in Apc and lacking intestinal epithelial IKKα, produced ...
Tetraamminedichloridochromium(III)bromide[Cr(NH3)4Cl2]Br is a coordination compound. Write its IUPAC name.
(CESA1), and that a phospho-mimicking form of SHOU4L prevented the binding of SHOU4L to CESA1, underpinning a relationship between SHOU4L's control over cellulose synthesis and plant immunity. This research has, accordingly, recognized SHOU4/4L as a novel element within PTI, and has ...
