Background
Cervical cancer is a prevalent malignancy that significantly contributes to morbidity and mortality rates among women in developing nations. Although the association of KIF18A with various cancers has been established, its role in cervical squamous cell carcinoma (CESC) remains elusive.
Conclusion
KIF18A promotes tumor growth in CESC by modulating the PI3K/AKT signaling pathway through regulation of CENPE, making it a potential biomarker for diagnosis and prognosis as well as a therapeutic target.
Methods
The KIF18A impact on the progression of CESC and its underlying mechanism were investigated through comprehensive bioinformatics analysis utilizing publicly available datasets. The levels of KIF18A and CENPE were assessed in clinical CESC samples through western blotting and qRT-PCR. To discover the role and molecular pathways of KIF18A in CESC, a combination of experimental approaches, including wound-healing, flow cytometry, CCK-8, and Transwell assay, were employed.
Results
Our results demonstrate a significant KIF18A expression upregulation in CESC tissues in contrast to healthy tissues. In vitro, KIF18A upregulation was found to enhance cell growth, migration, and invasion and activate the PI3K/AKT signaling pathway while concurrently suppressing apoptosis. Conversely, downregulating KIF18A exhibited contrasting effects. Mechanistically, we observed a positive significant connection between KIF18A and CENPE in CESC cells.
