Genes associated with epithelial mesenchymal transition (EMT) in cervical cancer progression.

Cervical Cancer is the second most common gynecological malignancy affecting a large group of women worldwide. The molecular mechanism of cervical cancer progression is still not very clear. As a result, diagnosis of cervical cancer occurs at a very advanced stage when the disease has spread to its malignant stage, causing death in the majority of women. EMT is a major culprit associated with the malignant transformation of tumor cells during cancer progression and metastasis. Hence, identification of new biomarkers to detect cervical cancer at an early stage is essential to minimize incidence and mortality. The present study aims to identify Common Differentially Expressed Genes (DEGs) and early biomarkers associated with EMT in cervical cancer. The Datasets were downloaded from the Gene Expression Omnibus (GEO) database, with Accession numbers GSE26511, GSE67522, and GSE9750. Then, the Gene Ontology (GO), KEGG pathway enrichment analysis, and protein-protein interactions (PPI) were done. Further hub genes were identified by molecular interaction networks using Cytoscape from the constructed network of DEGs. Afterwards, survival analysis was performed to assess the prognostic significance of eight hub genes associated with EMT in cervical cancer. A total of 11,339 overlapping DEGs were identified from all three datasets, among all the total 61 DEGS, and 8 hub genes were linked to the EMT pathway. Our study suggests that these eight hub genes, CDH1, CDH2, MMP2, CD44, FN1, FGF2, SNAI1, and SNAI2, may be critically associated with EMT progression. Among the eight identified EMT hub genes, CDH2 (N-cadherin) demonstrated a significant association with overall survival, while FN1 (fibronectin) was notably linked to disease-free survival, underscoring their prognostic value in cervical cancer. Based on these findings, our study suggests that CDH1, CDH2, MMP2, CD44, FN1, FGF2, SNAI1, and SNAI2 hold potential diagnostic and prognostic significance in the progression of cervical cancer.
