The failure of current glioma therapies is mainly due to the ability of the tumor cells to invade extensively the surrounding healthy brain tissue, hence escaping localized treatments. Neural stem cells (NSC) are able to home in on tumor foci at sites distant from the main tumor mass, possibly enabling treatment of scattered glioma clusters. To make the strategy more effective, we performed a cDNA expression library screening to identify the candidate genes that once overexpressed would enhance the tropism of NSCs for gliomas. Here, we show that a previously unannotated gene, the one encoding
transmembrane protein 18
(
TMEM18
), is one such gene. Overexpression of
TMEM18
was seen in the current study to provide NSCs and neural precursors an increased migration capacity toward
glioblastoma
cells in vitro and in the rat brain. Functional inactivation of the
TMEM18
gene resulted in almost complete loss of the migration activity of these cells. Thus,
TMEM18
is a novel cell migration modulator. Overexpression of this protein could be favorably used in NSC-based glioma therapy.
