To clarify the role of PDCD11 in cancers, we first compared the expression levels of PDCD11 in cancer and normal tissues by using Gene Expression Profiling Interactive Analysis 2 (GEPIA2) (http://gepia2.cancer-pku.cn/) [22] to analyze the data from TCGA [10] and the GTEx [11] databases. Here, PDCD11 is linked to cancer.
