CPZ and neuroblastoma: 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).
