STAT3
STAT3 is a widely expressed STAT family transcription factor that regulates cellular growth, differentiation, survival, immunity, hematopoiesis, and cell migration[1]. Mechanistically, cytokines and growth factors activate JAKs, phosphorylate STAT proteins, promote STAT dimerization, and drive nuclear transcriptional regulation[2]. In inflammatory disease models, STAT3 shows strong tyrosine phosphorylation in human ulcerative colitis, Crohn’s disease, and DSS-induced mouse colitis, where IL-6 deficiency reduces colitis and STAT3 activation[3]. In cancer models, persistent STAT3 activation supports proliferation, survival, invasion, metastasis, immune evasion, and drug resistance, making STAT3 signaling a practical axis for tumor biology research[1][4]. Compared with related isoforms, STAT1 knockout mice mainly show impaired interferon signaling, while STAT3 is emphasized in IL-6-linked inflammation, tumor progression, and Th17-related immune dysfunction[2][5]. For experimental applications, JAK/STAT inhibitors such as AG490 and AZD1480 reduce STAT1/STAT3 activation in renal ischemia-reperfusion and α-synuclein neuroinflammation models[6][7].
