摘要：
Background/Aim: Chloride intracellular channel 1 (CLIC1) is a member of the chloride channel protein family. The aim of this study was to clarify the role of CLIC1 in lung adenocarcinoma. Patients and Methods: The expression levels of CLIC1 in 74 patients with completely resected lung adenocarcinoma were analyzed by immunohistochemistry. Overall survival was assessed in relation to the expression level of CLIC1. Moreover, in the lung cancer cell lines A549 and PC9, CLIC1 expression was inhibited by small interfering RNA. The function of CLIC1 was analyzed in these cell lines. Results: High expression of CLIC1 was associated with short overall survival compared to low expression (p=0.0327). Multivariate analysis revealed that CLIC1 expression was an independent prognostic factor. Knockdown of CLIC1 inhibited cell proliferation and migration through suppression of the p38 MAPK signaling pathway in A549 and PC9 cells. Conclusion: CLIC1 may be a useful prognostic factor in lung adenocarcinoma.
