To investigate the biological role and underlying mechanism of SLC25A32 in GBM, LN229 and GBM#P3 cells with relatively higher expression of SLC25A32 were transfected with two independent siRNAs or negative control, and knockdown efficiency of the siRNAs was confirmed by qRT-PCR and western-blotting (Fig. 3A, B, D). Here, SLC25A32 is linked to glioblastoma.
