Eventually, we went the extra mile to investigate the survival curves of 33 TCGA cancer types using GEPIA database, revealing DDR1 expression to be significantly correlated with DFS in CHOL and KICH, OS in mesothelioma (MESO), and both OS and DFS in KIRC (Supplementary Figures S1–3). The gene discussed is DDR1; the disease is mesothelioma.
