Activation of NF-κB-Inducing Kinase in Islet β Cells Causes β Cell Failure and Diabetes
Mol Ther 2020 Nov 4;28(11):2430-2441.PMID:32730745DOI:10.1016/j.ymthe.2020.07.016.
Islet β cell death has been proved to contribute to diabetes. Studies suggest that the activation of nuclear factor κB (NF-κB)-inducing kinase (NIK) is involved in the β cell dysfunction encountered in obesity. However, the pathological significance of NIK activation in diabetes remains largely unknown. Here, we report that β cell-specific overexpression of NIK (β-NIK-OE) results in spontaneous diabetes in male mice at a young age (≥10 weeks of age), which is likely due to insulin deficiency, β cell death, and insulitis. Importantly, inhibiting the kinase activation of NIK by the small molecule B022 prevents NIK- or H2O2-induced β cell death and also reduces streptozotocin (STZ)-induced β cell death while ameliorating hyperglycemia, suggesting that the kinase activity of NIK is essential in inducing islet inflammation, β cell death, and diabetes. In all, this study not only uncovers a role of NIK in β cell failure but also provides a potential therapeutic target for the treatment of diabetes.
A small-molecule inhibitor of NF-κB-inducing kinase (NIK) protects liver from toxin-induced inflammation, oxidative stress, and injury
FASEB J 2017 Feb;31(2):711-718.PMID:27871061DOI:10.1096/fj.201600840R.
Potent and selective chemical probes are valuable tools for discovery of novel treatments for human diseases. NF-κB-inducing kinase (NIK) is a key trigger in the development of liver injury and fibrosis. Whether inhibition of NIK activity by chemical probes ameliorates liver inflammation and injury is largely unknown. In this study, a small-molecule inhibitor of NIK, B022, was found to be a potent and selective chemical probe for liver inflammation and injury. B022 inhibited the NIK signaling pathway, including NIK-induced p100-to-p52 processing and inflammatory gene expression, both in vitro and in vivo Furthermore, in vivo administration of B022 protected against not only NIK but also CCl4-induced liver inflammation and injury. Our data suggest that inhibition of NIK is a novel strategy for treatment of liver inflammation, oxidative stress, and injury.-Ren, X., Li, X., Jia, L., Chen, D., Hou, H., Rui, L., Zhao, Y., Chen, Z.
