Promoted migration, invasion and metastasis, and reduced the sensitivity of NSCLC cells to docetaxel. Results: Overexpression of TPX2 was related to the poor prognosis of NSCLC. Gene expression was detected via Western blot and real time PCR (RT-qPCR). Exosomes were extracted by differential centrifugation from the culture supernatant, and their functions were investigated by co-culture with tumor cells. An in vivo lung homing mouse model was used to further confirmed the role of TPX2 on metastasis. Stable TPX2 overexpression cell lines with were constructed by lentivirus infection, and the effect of TPX2 on proliferation, migration, invasion and chemoresistance to docetaxel was characterized by the CCK8, wound healing, transwell, colony formation assay and FACS. Methods: Bioinformatics analysis was used to analyze the relationship between TPX2 and the clinicopathological features of NSCLC. However, the role and mechanism of Targeting protein for Xenopus kinesin-like protein 2 (TPX2), which is highly expressed in NSCLC, is still unclear.
