| Outline of Final Research Achievements |
We have investigated the impact of estradiol (E2) in the induction of MDSC as well as the roles of E2-induced MDSC in maternal-fetal tolerance or cervical cancer progression during pregnancy. We have found that E2 enhanced the proliferation of bone marrow (BM) cells, and stimulated the differentiation of BM cells into MDSC. We also found that increased E2 level during pregnancy is involved in the maternal-fetal tolerance as well as cervical cancer progression, which read to the enhanced progression of cervical/breast cancers during pregnancy. Finally we identified a novel agent PM01183, which exhibits strong inhibitory effects on MDSCs. We are conducting clinical researches to verify these preclinical findings in human.
