Numerous studies have demonstrated constitutive activation of STAT3 in a wide variety of human Accepted 27 December 2013 tumors, including hematological malignancies (leukemias, lymphomas, and multiple myeloma) as well as Available online 2 January 2014 diverse solid tumors (such as head and neck, breast, lung, gastric, hepatocellular, colorectal and prostate cancers). There is strong evidence to suggest that aberrant STAT3 signaling promotes initiation and progression of human Keywords: STAT3 cancers by either inhibiting apoptosis or inducing cell proliferation, angiogenesis, invasion, and metastasis.
