GATA3 and neuroblastoma: IMR32, Kelly and NGP neuroblastoma cell lines, all of which expressed high levels of GATA3 sense RNA and GATA3 protein (Fig. 3A,B), were transfected with siRNAs to knock-down GATA3 expression, and then cell proliferation and cell death were assessed by a variety of assays (Fig. 5, Supplementary Fig. S4).
