Kinesin family member 2A high expression correlates with advanced tumor stages and worse prognosis in non‐small cell lung cancer patients

Background This present study was to explore the association of kinesin family member 2A (KIF2A) expression with clinicopathological features and survival profiles, and the effect of KIF2A on cell proliferation and chemosensitivity in non‐small cell lung cancer (NSCLC). Methods Tumor and paired adjacent specimens were collected from 380 patients with NSCLC underwent resection for immunohistochemistry assay of KIF2A expression. In vitro, the effect of KIF2A on cell proliferation, chemosensitivity to cisplatin/vinorelbine was detected via KIF2A plasmids transfection into NCI‐H1299 NSCLC cells. Results Kinesin family member 2A expression was upregulated in tumor tissues compared with adjacent tissues, and tumor tissue KIF2A high expression was associated with higher pathological grade (P
