Platelet factor-4 variant 1 (PF4V1) was recently described as a natural non-allelic gene variant of platelet factor-4 (PF4), which has been closely associated with the growth and metastasis of various cancers. Our previous research showed that PF4V1 was related to oral squamous cells carcinoma (OSCC) metastasis. Howerver, it is still not clear about the functional role of PF4V1 in OSCC. In this study, stably transfected cell lines were constructed and the expression level of PF4V1 was verified by real‐time polymerase chain reaction (RT-PCR) and western blot. The effect of PF4V1 on proliferation, migration, invasion, and apoptosis of oral cancer (OC) cells were detected. Moreover, a xenograft tumor model was constructed to evaluate the effect of PF4V1 on OSCC in vivo. Indicators of Wnt/β-catenin, angiogenesis and epithelial-mesenchymal transition (EMT) pathways were also examined. Stable cell lines with overexpression and inhibited expression of PF4V1 were constructed successfully. After stable transfection, PF4V1 significantly promoted the proliferation, migration, and invasion of OC cells in vitro, and their tumor formation in vivo. Furthermore, PF4V1 remarkably promoted the expression of β-catenin, VEGF, and FGF but suppressed the expression of GSK-3β. There was no statistically significant correlation between PF4V1 and EMT pathway. This study provides evidence that PF4V1 promotes the proliferation, migration, invasion and tumor formation of OC cells by regulating the Wnt/β-catenin pathway and angiogenesis. Our findings suggest that PF4V1 could be a very promising target of OSCC therapy in the future.

PF4V1通过调节Wnt /β-catenin途径和血管生成影响口腔鳞状细胞癌的进展

血小板因子4变异体1(PF4V1)最近被描述为血小板因子4(PF4)的天然非等位基因变异体,与多种癌症的生长和转移密切相关。我们先前的研究表明PF4V1与口腔鳞状细胞癌(OSCC)转移有关。但是,尚不清楚PF4V1在OSCC中的功能作用。在这项研究中,构建了稳定转染的细胞系,并通过实时聚合酶链反应(RT-PCR)和Western blot验证了PF4V1的表达水平。检测到PF4V1对口腔癌细胞(OC)增殖,迁移,侵袭和凋亡的影响。此外,建立了异种移植肿瘤模型以评估PF4V1对OSCC的体内作用。Wnt /β-catenin的指标,还检查了血管生成和上皮-间质转化(EMT)途径。成功构建了PF4V1过表达和表达受抑制的稳定细胞系。稳定转染后,PF4V1在体外显着促进OC细胞的增殖,迁移和侵袭,并在体内促进肿瘤的形成。此外,PF4V1显着促进了β-catenin,VEGF和FGF的表达,但抑制了GSK-3β的表达。PF4V1与EMT途径之间无统计学意义的相关性。这项研究提供了证据,PF4V1通过调节Wnt /β-catenin途径和血管生成来促进OC细胞的增殖,迁移,侵袭和肿瘤形成。我们的发现表明,PF4V1将来可能成为OSCC治疗的非常有希望的靶标。成功构建了PF4V1过表达和表达受抑制的稳定细胞系。稳定转染后,PF4V1在体外显着促进OC细胞的增殖,迁移和侵袭,并在体内促进肿瘤形成。此外,PF4V1显着促进了β-catenin,VEGF和FGF的表达,但抑制了GSK-3β的表达。PF4V1与EMT通路之间无统计学意义的相关性。这项研究提供了证据,PF4V1通过调节Wnt /β-catenin途径和血管生成来促进OC细胞的增殖,迁移,侵袭和肿瘤形成。我们的发现表明,PF4V1将来可能成为OSCC治疗的非常有希望的靶标。成功构建了PF4V1过表达和表达受抑制的稳定细胞系。稳定转染后,PF4V1在体外显着促进OC细胞的增殖,迁移和侵袭,并在体内促进肿瘤的形成。此外,PF4V1显着促进了β-catenin,VEGF和FGF的表达,但抑制了GSK-3β的表达。PF4V1与EMT途径之间无统计学意义的相关性。这项研究提供了证据,PF4V1通过调节Wnt /β-catenin途径和血管生成来促进OC细胞的增殖,迁移,侵袭和肿瘤形成。我们的发现表明,PF4V1将来可能成为OSCC治疗的非常有希望的靶标。稳定转染后,PF4V1在体外显着促进OC细胞的增殖,迁移和侵袭,并在体内促进肿瘤形成。此外,PF4V1显着促进了β-catenin,VEGF和FGF的表达,但抑制了GSK-3β的表达。PF4V1与EMT途径之间无统计学意义的相关性。这项研究提供了证据,PF4V1通过调节Wnt /β-catenin途径和血管生成来促进OC细胞的增殖,迁移,侵袭和肿瘤形成。我们的发现表明,PF4V1将来可能成为OSCC治疗的非常有希望的靶标。稳定转染后,PF4V1在体外显着促进OC细胞的增殖,迁移和侵袭,并在体内促进肿瘤形成。此外,PF4V1显着促进了β-catenin,VEGF和FGF的表达,但抑制了GSK-3β的表达。PF4V1与EMT途径之间无统计学意义的相关性。这项研究提供了证据,PF4V1通过调节Wnt /β-catenin途径和血管生成来促进OC细胞的增殖,迁移,侵袭和肿瘤形成。我们的发现表明,PF4V1将来可能成为OSCC治疗的非常有希望的靶标。和FGF,但抑制了GSK-3β的表达。PF4V1与EMT途径之间无统计学意义的相关性。这项研究提供了证据,PF4V1通过调节Wnt /β-catenin途径和血管生成来促进OC细胞的增殖,迁移,侵袭和肿瘤形成。我们的发现表明,PF4V1将来可能成为OSCC治疗的非常有希望的靶标。和FGF,但抑制了GSK-3β的表达。PF4V1与EMT通路之间无统计学意义的相关性。这项研究提供了证据,PF4V1通过调节Wnt /β-catenin途径和血管生成来促进OC细胞的增殖,迁移,侵袭和肿瘤形成。我们的发现表明,PF4V1将来可能成为OSCC治疗的非常有希望的靶标。
