Abstract:
Objective To investigate the mRNA and protein expression of GPX3 gene in non-small cell lung cancer (NSCLC) patients, and then discuss the clinical significance of GPX3 in NSCLC patients. Methods Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to detect the GPX3 mRNA and protein levels in NSCLC tissues and adjacent non-cancerous normal lung tissues from 60 patients undergoing surgical treatment. The correlation between the expression levels of GPX3 and clinicopathological features was analyzed. Results The relative expression value of GPX3 mRNA was higher in adjacent non-cancerous tissues than in non-small cell lung cancer tissue (P < 0.05). GPX3 mRNA expression was significantly correlated with TNM stage、differentiation and lymph node metastasis. The integral optical density value of GPX3 protein confirmed was lower in adjacent non-cancerous tissues than in non-small cell lung cancer tissues (P < 0.05). In additional, the expression of GPX3 was related to TNM stage and lymph node metastasis. Conclusion The expression of GPX3 gene may play an important role in the carcinogenesis and progression of NSCLC.
