EGFR and cancer: Expression of Sorcin and EGFR at protein level showed positive correlation in tumors, both overall (R =  + 0.12, by pooling all tumor data in the cProSite database) and in the majority of the considered cancer types when evaluated individually (positive correlation in 6 out of 7 tumors with at least 30 patients with data on abundance in tumors and adjacent normal tissue; Supplementary Fig. 2).
