It was selected particularly for its potent cytotoxicity against the two main sub-populations of ovarian cancer: chemo-resistant CD44+/MyD88+ ovarian cancer stem cell (OCSC) clones as well as in chemo-sensitive CD44−/MyD88− ovarian cancer cell (OCC) lines and potent activity in in vivo model of disseminated ovarian cancer. This evidence concerns the gene MYD88 and ovarian carcinoma.
