PLAGL1 and cervical cancer: Interestingly, the molecular pattern of high Zac1 expression was significantly and commonly correlated with the epithelial mesenchymal transition in three sources, especially in cervical cancer patients with high Zac1 expression in TCGA-CESC, suggesting that tumor with high Zac1 expression may have enriched EMT related gene expression, which may correspond to enhanced cell migration ability comparing to those with lower Zac1 expression.
