Similarly, when Cyp11b1 was deleted in vitro by transducing Cyp11b1L/L tumour organoids with lentiviral Cre recombinase, a similar growth advantage of Cyp11b1‐proficient tumours over Cyp11b1‐deleted tumours was observed upon s.c. transplantation (Fig. S3B–E). This evidence concerns the gene CYP11B1 and neoplasm.
