DHCR7 and lung cancer: Among these genes, only DHCR7 was highly expressed in both BRCA and LUAD patients in comparison to healthy controls (Supplementary Fig. S7), and its higher expression significantly correlated with (i) the poor overall survival of BRCA (Supplementary Fig. S8A) and lung cancer (Supplementary Fig. S9A) patients, and (ii) with the lack of response to chemotherapies in BRCA patients (Supplementary Fig. S8B).
