Abstract

Glioblastoma-derived stem cells (GSCs) are responsible for the cancer resistance to therapies. We show here that GSC-enriched neurospheres are resistant to the treatment of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) due to the insufficient expression of the death receptor DR4 and DR5 and the overexpression of cellular Fas-associated death domain-like interleukin-1β-converting enzyme-inhibitory protein (c-FLIP). However, treatment with cisplatin leads to the upregulation of DR5 and downregulation of c-FLIP and restores TRAIL apoptotic pathway in the neurospheres. This study suggests that the combined treatment of TRAIL and cisplatin can induce apoptosis in GSCs and thus provide an effective treatment of glioblastomas.
