Drug‐response modelling with the Genomics of Drug Sensitivity in Cancer (GDSC) dataset indicated that tumours with high DCAF7 expression are more sensitive to the HSP90 inhibitor 17‐AAG and to docetaxel; in fact, DCAF7 levels inversely correlated with IC50 values for >20 anti‐cancer agents (Figure 8C and Table S16), pointing to a broad influence on chemosensitivity. The gene discussed is DCAF7; the disease is cancer.
