Abstract:
Objective:To investigate the expression of silencing kinesin KIF4A in thyroid cancer tissues and its relationship with clinicopathological characteristics of thyroid cancer patients, and to assess the role of KIF4A in the progression of thyroid cancer.Methods:The expression of KIF4A in normal thyroid tissues and the thyroid cancer population and its relationship with disease-free survival of patients were analyzed online by gene expression interaction analysis (GEPIA) database, and the expression of KIF4A in tumor tissues and paraneoplastic tissues of thyroid cancer patients was assessed by immunohistochemical assays. The patients were divided into high- and low-expression groups according to the staining intensity, and the correlation between the expression of KIF4A and clinicopathological features was analyzed. The effect of KIF4A on the proliferation of thyroid cancer cells was explored by a clone formation assay and an MTT assay.Results:According to the analysis of the web-based database, KIF4A showed significantly high expression in human thyroid cancer tissues, and disease-free survival was significantly lower in highly expressed patients. The results of the case analysis showed that the correlation between KIF4A expression intensity and gender, age, and lymph node metastasis in thyroid cancer patients was not statistically significant (all P>0.05), and the correlation with TNM stage and intraglandular dissemination was statistically significant (all P<0.05). The results of the colony formation assay and the MTT assay showed that the expression of KIF4A promoted the proliferation of thyroid cancer cells ( P<0.05). Conclusions:KIF4A can promote the progression of thyroid cancer and has the potential to become a new therapeutic target for thyroid cancer.
