Multiple kinases regulating NF-κB and STAT3 pathways

The term Multiple kinases regulating NF-κB and STAT3 pathways refers to a functional group of enzymes, primarily Janus kinases (JAK1, JAK2, JAK3) and IκB kinases (IKKα, IKKβ), that orchestrate the activation of two master transcription factors: Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-κB) and Signal Transducer and Activator of Transcription 3 (STAT3) (Grivennikov & Karin, 2010, PubMed: 20478251). These pathways are critical regulators of the innate and adaptive immune systems, cell survival, and proliferation, and they frequently exhibit synergistic crosstalk in the tumor microenvironment (Fan et al., 2013, PubMed: 23606504). In many cancers and chronic inflammatory conditions, these kinases are constitutively active, leading to the persistent expression of genes that promote tumor growth, metastasis, and resistance to apoptosis (Yu et al., 2009, PubMed: 19890341). Therapeutic intervention typically involves the use of JAK inhibitors, IKK inhibitors, or multi-kinase inhibitors to disrupt these signaling cascades and restore normal cellular homeostasis (He et al., 2010, PubMed: 20843999). Because this entry describes a collective set of proteins involved in a signaling network rather than a single molecular entity, it is classified as a pathway-level target rather than a specific canonical receptor or enzyme.
