In addition, support for these finding further is provided by the evidence that treating human ovarian cancer with STAT3 inhibitor HO-3867, a novel compound which decreases the level of Tyrosine-phosphorylated STAT3 (pSTAT3) and then followed by a decline of cyclin D1, survivin and Bcl-2 as well as an ascent of cleaved PARP, caspase-3 and caspase-7, gives rise to suppression of cell proliferation and survival42-44 . The gene discussed is STAT3; the disease is ovarian carcinoma.
