Protein domain structure of genes commonly mutated in LTTs. Overview of the domain structures of (a) ATP7B, (b) NRXN2 (Neurexin-2), (c) FAM205A, and (d) HECW1 (NEDL1). Mutations found in the TCGA data set as annotated from cBioportal and mutations found in LTTs were included. All mutations in the LTTs are missense mutations except for one FAM205A mutation in RT-112 (Table S14). (e) ATP7B mRNA expression was measured by qRT-PCR in parental UCCs and LTTs after treatment with siRNA against ATP7B or a non-targeting control. SDHA mRNA was used as a reference. (f) Relative cell viability after 48 h cisplatin treatment as measured by CellTiterGlo assay in parental UCCs and LTTs transfected with siRNA targeting ATP7B or a non-targeting negative control siRNA. Values represent the mean ± SD of biological quadruplicates, *p < 0.05 compared to non-targeting control. HECT: Homologous to the E6-AP Carboxyl Terminus; HECWN: HECTW1 N-terminal domain; H: Helical bundle; C2: C2 domain; WW: WW domain; HMA: Heavy metal-associated domain.
