Objective:
For investigating Dbx2's expression in endometrial cancer (EC) and its effect on prognosis of patients with EC.
Methods:
A comparison was performed in the Cancer Genome Atlas (TCGA) database in terms of the expression profiling of EC and the survival data. To obtain differential expression genes (DEGs), Volcano plot and Venn analysis were adopted. DEGs function was performed by carrying out the GO annotation analysis (GO) and gene set enrichment analysis (GSEA). In clinical EC samples, PCR was applied to the verification of Dbx2's expression.
Results:
Dbx2 was a downregulated expression in tumor tissues. Dbx2 can have a poor prognosis role in EC by regulating the apoptotic signaling pathway and the immune pathway. Lower expression of Dbx2 was related to lymph node metastasis and FIGO stage.
Conclusion:
Dbx2 is downregulated in endometrial cancer, which serves as a biomarker to predict poor prognosis.
