Furthermore, increased FAO enzymes and CD47 were detected in three human RR GBM cell lines compared to the corresponding parental WT GBM cells (Fig. 3c) and immunofluorescence revealed that co-expression of CPT1A, CPT2, or ACAD9 with CD47 was observed in RR cells (Supplementary Fig. 4b–d). Here, CPT2 is linked to glioblastoma.
