STAT3 and neoplasm: The increase in the secretion of IL-10 and TGF-β1 via the JAK2-STAT3 pathway activated by B7-H3 has been suggested as an underlying tumor-promoting mechanism [157], and AKT/mTOR might also be involved in tumorigenesis, as it was inhibited in SiHa cervical cancer cells by B7-H3 overexpression [158].
