Effect of TPP-conjugated peptides on transmembrane potential of mitochondria in (A) SNB-19 and (B) LN-229 glioblastoma cells after 2-h treatment according to JC-1 fluorescence. Mean ± SEM (n = 4, ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001 vs. Ctrl) are shown. Dotted line shows the signal for untreated cells.
