{"entity":{"id":"stat3","kind":"target","name":"STAT3","aka":["signal transducer and activator of transcription 3","Signal transducer and activator of transcription 3"],"tldr":"STAT3 (Signal transducer and activator of transcription 3) is a gene that drives cell growth when it is altered. The public catalogues list it as a drug target, an oncogene driver and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Non-Hodgkin lymphoma, Leukaemia, Skin cancer and 5 more.","summary":"Signal transducer and transcription activator that mediates cellular responses to interleukins, KITLG/SCF, LEP and other growth factors. Once activated, recruits coactivators, such as NCOA1 or MED1, to the promoter region of the target gene. May mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4.\n\nCIViC holds 2 clinical evidence items and 0 assertions across 4 variants. Open Targets scores its association with cancer at 0.78 (direct and indirect evidence; datatypes clinical 0.19, affected pathway 0.84, literature 1.00, genetic association 0.15, somatic mutation 0.97). IntOGen calls it a driver in 7 cohorts (7 activating, 0 loss-of-function), covering Diffuse Large B-Cell Lymphoma, NOS, Lymphoid Neoplasm, Malignant Lymphoma, Non-Hodgkin Lymphoma.","asOf":"2026-09-23","links":[{"label":"HGNC HGNC:11364","url":"https://www.genenames.org/data/gene-symbol-report/#!/hgnc_id/HGNC:11364"},{"label":"UniProt P40763","url":"https://www.uniprot.org/uniprotkb/P40763/entry"},{"label":"NCBI Gene 6774","url":"https://www.ncbi.nlm.nih.gov/gene/6774"},{"label":"Ensembl ENSG00000168610","url":"https://www.ensembl.org/Homo_sapiens/Gene/Summary?g=ENSG00000168610"}],"tags":["cancer-genes-wave"],"related":["civic","open-targets","intogen"],"cancers":["non-hodgkin-lymphoma","leukaemia","skin-cancer","lung-cancer","ovarian","biliary-tract-cancer","dlbcl","all-leukemia"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":["inflammation-nfkb","jak-stat","nsclc-signalling","rtk-activation"],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":["Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling.

Once activated, recruits coactivators, such as NCOA1 or MED1, to the promoter region of the target gene. May mediate cellular responses to activated FGFR1, FGFR2, FGFR3 and FGFR4. Upon activation of IL6ST/gp130 signalling by interleukin-6 (IL6), binds to the IL6-responsive elements identified in the promoters of various acute-phase protein genes. Activated by IL31 through IL31RA. Acts as a regulator of inflammatory response by regulating differentiation of naive CD4(+) T-cells into T-helper Th17 or regulatory T-cells (Treg): acetylation promotes its transcription activity and cell differentiation while deacetylation and oxidation of lysine residues by LOXL3 inhibits differentiation.
