However, expression databases suggested that ARHGAP36 is expressed in neuroblastoma cell lines (www.nextbio.com) and we indeed identified its expression at comparable levels in NGP and CLB-GA cells40, 41, where endogenous ARHGAP36 localized similarly to the overexpressed protein (Fig. 8a; Supplementary Fig. 8a–c). The gene discussed is ARHGAP36; the disease is neuroblastoma.
