The decrease of LC3-II levels caused by XIAP knockdown was also observed in human neuroblastoma SK-N-SH cells (Supplementary Material, Fig. S1B) and in MCF10A cells, where we also confirmed that we could rescue the negative effects of XIAP knockdown by overexpressing XIAP in knockdown cells (Supplementary Material, Fig. S1C). Here, XIAP is linked to neuroblastoma.
