Background:
The TFAP2 family of transcription factors, regulating gene expression related to vertebrate evolution, have been studied extensively in human cancer. However, the distinct roles of each TFAP2 in the expression and prognostic significance of lung carcinoma have not been elucidated yet.
Objective:
This study is aimed to identify the mRNA expression and prognostic value of TFAP2 family in human lung cancer.
Methods:
The transcriptional and survival data of TFAP2s in patients with lung cancer were obtained via ONCOMINE, LinkedOmics, GEPIA, cBioPortal, Kaplan-Meier Plotter and Human Protein Atlas databases.
Results:
The results showed that expression levels of TFAP2A and TFAP2C were higher in lung adenocarcinoma and squamous cell carcinoma tissues than in normal lung tissues, whereas no difference was found in the TFAP2B expression level. TFAP2A was related to an unfavorable overall survival in lung cancer and its upregulation was significantly related to the overall survival in patients with smoking, non-chemotherapy and non-radiotherapy.
Conclusion:
This study implied that TFAP2A was a reliable prognostic factor, which could be a potential marker for improving survival and prognostic accuracy of lung cancer patients.
