(F) Nude mice were inoculated with 4 × 106 HL60 tumour cells following transfection of control (shControl) or UVRAG (shUVRAG)‐specific shRNA and treated with doxorubicin (10 mg/kg) beginning at day 7. Tumours were measured twice weekly, and volumes were calculated for 21 days (n=10, *P0.05; shControl+Doxo compared with shUVRAG+Doxo).
