Since Stat3 phosphorylation at Tyr705 is elevated in cervical and endometrial cancer tissues and Stat3 pathway has been shown to participate in oncogenesis (Bromberg et al, 1999; Bowman et al, 2000), we examined whether the inhibition of Stat3 pathway by dnStat3 in cervical cancer cells could suppress cancer cell growth. Here, STAT3 is linked to endometrial cancer.
