SLC27A3 and glioblastoma: Immunoblot analyses showed that ACSVL3 expression was found to be absent or lower in adherent GBM cell lines not enriched for GBM stem cells (i.e. U373 and U87, respectively,) in comparison to more elevated ACSVL3 expression in HSR-GBM1A and HSR-GBM1B neurosphere cells (Figure 1A).
