Abstract
The Kinesin family member 2a (KIF2A), that belongs to the Kinesin-13 microtubule depolymerases, plays an important role in cancer cell proliferation, migration and apoptosis in various types of cancer such as gastric cancer, breast cancer, and squamous cell carcinoma of the oral tongue, but, its role and mechanism in lung adenocarcinoma (LUAD) is largely unknown. The present study reported that KIF2A was overexpressed in LUAD tissues as compared with adjacent normal tissues. KIF2A was closely correlated with TNM stage and lymph node metastasis (Pâ¯<â¯0.01), whereas, no similar relationships between KIF2A and age, gender, smoking and differentiation. Multivariate analysis indicated that hyperexpression of KIF2A in LUAD was an independent risk factor for worse overall survival in LUAD patients (HR: 3.135, 95%CI: 1.331-7.112, pâ¯<â¯0.05). In vitro, KIF2A knockdown markedly reduced LUAD cell A549 migration and could regulate epithelial-mesenchymal transition. Furthermore, silencing KIF2A inhibited cell proliferation and induced apoptosis in lung adenocarcinoma(LUAD) cells. In conclusion, KIF2A may serve as a valuable prognostic indicator and promising therapeutic target of LUAD.
