SLC30A9 and neuroblastoma: To test possible effects of the mutation on this activity of SLC30A9, we performed a dual-luciferase reporter assay in neuroblastoma (SH-SY5Y) cells transfected with either wild-type or mutant SLC30A9-overexpressing constructs [pCDNATM 3.1 (−) under control of the CMV promoter].
