CCDC88A and cancer: To investigate whether CCDC88A is correlated with poor prognosis in LIHC, the data of the cancer genome ATLAS (TCGA) and the genotype-tissue expression (GTEx) (GEPIA, http://gepia.cancer-pku.cn/index.html) was employed and the results revealed that the expression of CCDC88A is upregulated in LIHC tumor tissue normalized to normal liver tissues (Figure 1A), which is not observed in COAD and LUAD.
