The antitumor effects of methyl-β-cyclodextrin against primary effusion lymphoma via the depletion of cholesterol from lipid rafts.


PMID 25446086

Abstract

Primary effusion lymphoma (PEL) is a subtype of aggressive and chemotherapy-resistant non-Hodgkin lymphoma that occurs predominantly in patients with advanced AIDS. In this study, we examined the antitumor activity of methyl-β-cyclodextrin (M-β-CyD) in vitro and in vivo. M-β-CyD quickly induced caspase-dependent apoptosis in PEL cells via cholesterol depletion from the plasma membrane. In a PEL xenograft mouse model, M-β-CyD significantly inhibited the growth and invasion of PEL cells without apparent adverse effects. These results strongly suggest that M-β-CyD has the potential to be an effective antitumor agent against PEL.
