Fig. 2

Lipid peroxides were detected by flow cytometry after incubation with C11-BODIPY in SHEP (A) or SK-N-BE2 (B) cells with or without MYCN. DFO, desferrioxamine, n = 3. C Cell viabilities of SHEP cells with or without MYCN overexpression incubated with Erastin (left), RSL3 (middle), or RSL3 combined with either ferroptosis inhibitor (10 μM DFO, 1 μM Ferr-1), apoptosis inhibitor (20 μM z-VAD), or necroptosis inhibitor (2 μM Necrostatin-1) (right). D Cell viabilities of SK-N-BE2 cells with or without MYCN knockdown incubated with Erastin or RSL3. E Metabolic analysis of SHEP cells with or without MYCN. Z-score ±2.75 is corresponding to p = 0.01 and depicted as a dotted line. Data are presented as mean ± SD of three replicates. Two-tailed unpaired t-tests were performed to calculate p values. **p < 0.01.
