We observed that ATP13A3 silencing in both MYCN‐amplified (KELLY) and non‐MYCN‐amplified (SH‐SY5Y) neuroblastoma cells significantly attenuated cell growth and that this was a dose‐dependent effect as less effective silencing was associated with less pronounced effects on growth inhibition (Fig. 6B). Here, MYCN is linked to neuroblastoma.
