Research Abstract |
Ascites macrophages in advanced epithelial ovarian cancer(AdEOC) are involved in cancer metastasis and progression by modifying the tumor microenvironment. We investigated the function of macrophages in the ascites of advanced epithelial ovarian cancers and the cell-to-cell interactions between macrophages and EOC cells through Stat3 activation. M2 macrohpages in the ascitic fluid may influence epithelial ovarian cancer development via STAT3 activation. Macrohages differentiation could be targeted for development of anticancer therapeutic drugs. Furthermore, corosolic acid(CA), a triterpenoid compound, is contained in the leaves of the banaba plant(Lagerstroemia speciosa L.). The compound possesses various biological properties, including anti-diabetic, anti-obesity and anti-oxidative activities. We investigated the cytotoxicity of CA against human ovarian cancer cell lines. CA inhibited the proliferation of ovarian cancer cells by suppressing the activation of STAT3. Therefore, CA might be a potential new tool for tumor prevention and therapy.
