LC-3和P62在非小细胞肺癌中的表达及其临床特征分析
Expression and Clinical Significance of LC-3 and P62 in Non-small Cell Lung Cancer
摘要
Abstract
Background and objective LC-3 and P62, two of important autophagy-related proteins, were reported highly expressed in many kinds of human malignancies and associated with outcomes of the pa-tients. The purpose of this study was to investigate the expression status of LC-3 and P62 in non-small cell lung cancer patients and define the clinical-pathologic features. Methods 66 cases of non-small cell lung cancer pa-tients were employed. The expression of LC-3 and P62 were detected by immunohistochemistry. Results LC-3 was positive stained in 27 out of 66 cases (40.9%) and P62 was positive stained in 43 out of 66 cases (65.2%). LC-3 positive staining was more frequently in squamous cell carcinoma patients (P<0.05); while P62 positive staining was more frequently in late-stage adenocarcinoma patients with metastasis (P<0.05). There was a sig-nificant negative correlation between LC-3 and P62 expressions in non-small cell lung cancer tissues (rs=-0.065, P<0.001). Kaplan-Meier analysis showed that patients with positive LC-3 expression had favorable clinical out-comes compared with the patients with negative LC-3 expression (P<0.05). Conclusion LC-3 and P62 showed abnormal expression in non-small cell lung cancer tissues, suggesting that autophagy is involved in the occur-rence and development of NSCLC.关键词
