Moreover, targeting STAT3 in human breast cancer cells was reported to suppress the tumor progression by regulating the expression of crucial proteins in tumor milieu, such as survivin, chemokines (CCL5 and CXCL10) and proinflammatory cytokines (IL-6, IL-5, TNF-a, and IFN-γ) [183–185]. This evidence concerns the gene BIRC5 and neoplasm.
