ABSTRACT OBJECTIVE To investigate the effects of Mitoxantrone liposomes (Lipo-MIT) on the proliferation, migration and
cancer stem cell (CSCs) stemness of ovarian cancer cells, as well as to explore its mechanism of action based on the
phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) pathway. METHODS The effects of Lipo-MIT on cell proliferation,
migration and the stemness characteristics of CSCs were investigated through in vitro experiments. A human ovarian cancer A2780
cells xenograft tumor model of nude mouse was established to explore the effects of Lipo-MIT at doses of 2 and 5 mg/kg on the
safety of tumor-bearing mice, as well as in vivo tumor growth and the pathological characteristics of tumor tissues. The influence of
Lipo-MIT on the expression levels of PI3K/AKT pathway-related proteins, epithelial-mesenchymal transition related proteins, and
stemness related proteins in both cells and tumor tissues was also investigated. RESULTS The half maximal inhibitory
concentrations of Lipo-MIT against A2780, SK-OV3, and OV-CAR5 cells were 0.72, 5.41, and 2.77 μmol/L, respectively.
Compared with solvent control (0.1% dimethyl sulfoxide), 0.5-2.5 μmol/L Lipo-MIT significantly reduced the cell colony
formation rate, shortened the cell migration distance,
