We found that knock-down of GATA3 decreased CCND1 expression in neuroblastoma cell lines (Fig. 5, Supplementary Fig. S4) and that in tumour samples, there was high expression of CCND1 compared to FA and a good correlation between GATA3 and CCND1 expression (Supplementary Fig. S6), as found by others40,52,53. Here, CCND1 is linked to neuroblastoma.
