In BioTarget [4], we demonstrated how targets of TBX21 and GATA2 can be identified, respectively, for the differentiation of Th1 and Th2 immune cells by analyzing the respective ENCODE ChIP-Seq data over five different TCGA cancer cohort data sets, Stomach Adenocarcinoma (STAD), Breast Invasive Carcinoma (BRCA), Colon Adenocarcinoma (COAD), Lung Adenocarcinoma (LUAD), and Lung Squamous Cell Carcinoma (LUSC). This evidence concerns the gene TBX21 and gastric adenocarcinoma.
