PLAGL1 and neoplasm: In order to compare the commonality of high Zac1 expression in (1) cervical carcinoma tissues in TCGA-CESC, (2) normal versus tumor tissues in GSE7803, and (3) manipulated Zac1 overexpression versus control group in HeLa cells, GSEA approach was used to disclose the enriched gene-sets of biological processes.
