Using TCGA-Kidney Renal Clear Cell Carcinoma (KIRC) and TCGA-Kidney Renal Papillary Cell Carcinoma (KIRP) datasets publicly available in the ENCORI Pan-Cancer Analysis Platform (http://starbase.sysu.edu.cn/panCancer.php), we found that in both TCGA-RCC datasets, only the DUSP4 expression had a consistent and significantly negative relationship with ING4 (Figures 6A,B). The gene discussed is DUSP4; the disease is cancer.
