As expected in the case of SH-SY5Y neuroblastoma cells, which according to previous studies show a negligible expression of Apo D [52], we found that these cells exhibited a very scarce endogenous expression of Apo D only detected by immunocytochemistry, and that CPZ did not influence the apolipoprotein synthesis as observed in the images (Figure 2a) and the immunocytochemical quantification (Figure 2b,c). This evidence concerns the gene APOD and neuroblastoma.
