Using the estimation of stromal and immune cells in malignant tumor tissues using expression data (ESTIMATE) algorithm, we found a negative correlation between the expressions of AGK mRNA and immune scores in BRCA, Bladder Urothelial cancer (BLCA), Esophageal cancer (ESCA), Lung squamous cell cancer (LUSC), Lung adenocarcinoma (LUAD) and Rectum adenocarcinoma (READ) (Figure 1B). Here, AGK is linked to cancer.
