Background: This study was to explore the expression profile of endometrial carcinoma (EC) and identify the potential molecular mechanism and therapeutic targets. Methods: Differentially expressed genes (DEGs) and differentially expressed miRNAs (DEMs) were identified in EC using mRNA and miRNA sequencing data released by the Cancer Genome Atlas database; then, gene function and pathway of DEGs were analyzed based on the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway databases; finally, the transcription factors (TFs) latently regulating the DEGs and DEMs were predicted and a TF-miRNA-Gene network was then established to summarize the regulatory links between TFs, DEMs and DEGs. Results: One thousand five hundred and forty two upregulated and 1,885 downregulated DEGs, 34 upregulated and 12 downregulated DEMs were identified. The principal DEGs-enriched functions were cell differentiation, cell migration, and cell surface receptor signaling pathway. The DEGs-enriched cell signaling pathways including the MAPK, Wnt signaling pathway, and the p53 signaling pathway. As shown in the TF-miRNA-Gene network, TFs such as CPBP and GKLF, miRNAs such as miR-141-3p and miR-130b-3p, regulated most of DEGs and DEMs. Conclusion: These results may contribute to the study of the molecular mechanism and therapeutic targets in EC, and facilitate the discovery of new biomarkers for screening, diagnosis and monitoring.
