Abstract:
Objective:To investigate the expression level of poly ADP ribose polymerase 14(PARP14) in thyroid cancer and its relationship with the clinicopathologic characteristics of the patient with thyroid cancer and evaluate the role of PARP14 in the progression of thyroid cancer.Methods:The gene expression interaction analysis (GEPIA) database was used to analyze the expression of PARP14 in normal thyroid tissue and thyroid cancer tissue and its relationship with disease-free survival of patients. The expression of PARP14 in thyroid cancer tissue and adjacent tissues of the patient with thyroid cancer was evaluated by immunohistochemistry. According to the staining intensity, the patients were divided into the high expression group and the low expression group, and the correlation between the expression of PARP14 and clinical pathological characteristics was analyzed. The effect of PARP14 on the proliferation of thyroid cancer cells was investigated by clone formation testing and MTT testing.Results:The results of bioinformatics analysis and immunohistochemistry showed that PARP14 was overexpressed in thyroid cancer tissue, and the disease-free survival rate of the patient with high expression was lower. The expression level of PARP14 was correlated with tumor stage and intrathyroidal spread (all P<0.05). The results of the clonogenic assay and the MTT assay showed that the expression of KIF4A could promote the proliferation of thyroid cancer cells ( P<0.05). Conclusions:PARP14 is highly expressed in thyroid cancer and is related to the clinicopathological characteristics of patients, suggesting that it may be a therapeutic target for thyroid cancer.
