The aim of the present study was to reveal the clinicopathological significance and prognostic role of kinesin family member 23 (KIF23) in colorectal cancer (CRC) and characterize its biological function and the underlying mechanisms. Bioinformatics analysis, immunohistochemistry, Western blot and qRT-PCR were utilized to investigate the expression of KIF23 in CRC tissues. The CCK-8 assay, wound healing assay and Matrigel assay were used to detect cell proliferation, migration and invasion . Western blot, immunofluorescence staining and cell function experiment were performed to explore the underlying mechanism. The overexpression of KIF23 was associated with T stage, N stage, M stage and TNM stage, and CRC patients with high KIF23 expression had a worse prognosis. KIF23 knockdown inhibits CRC cells proliferation, migration and invasion . The mechanism study determined that KIF23 activates the Wnt/β-catenin signaling pathway by promoting the nuclear translocation of β-catenin to regulate the malignant behavior of CRC cells. These results suggest that KIF23 may act as a putative oncogene and a potential therapeutic target in CRC.
本研究旨在揭示驱动蛋白家族成员23(KIF23)在结直肠癌(CRC)中的临床病理意义和预后作用,并阐明其生物学功能及潜在机制。运用生物信息学分析、免疫组织化学、蛋白质印迹法和定量逆转录聚合酶链反应(qRT-PCR)研究KIF23在CRC组织中的表达。采用细胞计数试剂盒-8(CCK-8)检测法、伤口愈合检测法和基质胶检测法检测细胞增殖、迁移和侵袭能力。通过蛋白质印迹法、免疫荧光染色和细胞功能实验探究潜在机制。KIF23的过表达与T分期、N分期、M分期及TNM分期相关,KIF23高表达的CRC患者预后较差。敲低KIF23可抑制CRC细胞的增殖、迁移和侵袭。机制研究表明,KIF23通过促进β-连环蛋白的核转位激活Wnt/β-连环蛋白信号通路,从而调节CRC细胞的恶性行为。这些结果提示,KIF23可能是CRC中的一个假定癌基因和潜在治疗靶点。
