Nuclear factor kappaB (NF-kappaB) is regarded as a key regulator of inflammation; hence, several inflammatory diseases result from deregulation of NF-kappaB signaling. There is, however, also increasing evidence for a preponderant role of NF-kappaB in tumor development and progression. Constitutive activation of NF-kappaB activity by signaling defects, mutations or chromosomal rearrangements can be found in a wide variety of cancers. Additionally, a causal link between inflammation and cancer has been noted, which makes NF-kappaB an interesting target for development of both anti-inflammatory and anti-cancer therapeutics. Here, we review current knowledge of NF-kappaB signal transduction, focusing on the regulation of its transcriptional activity by post-translational modification of the NF-kappaB subunits.
核因子κB(NF-κB)被视为炎症的关键调节因子;因此,多种炎症性疾病是由NF-κB信号传导失调所致。然而,也有越来越多的证据表明NF-κB在肿瘤发生和发展中起主要作用。在多种癌症中都可发现,由于信号缺陷、突变或染色体重排导致NF-κB活性的组成性激活。此外,炎症与癌症之间的因果联系也已得到证实,这使得NF-κB成为开发抗炎和抗癌治疗药物的一个有趣靶点。在此,我们综述了目前关于NF-κB信号转导的知识,重点关注通过NF-κB亚基的翻译后修饰对其转录活性的调节。
