CTNNB1 and adrenal gland neoplasm: To investigate if mouse adrenal tumours were also sensitive, we analysed three models: two cell lines derived from adrenal tumours driven by SV40 T antigen, ATC1 (containing an activating Ctnnb1 mutation35) and ATC7; and primary cells derived from adrenal tissue from the Ctnnb1 mutant mice described above.
