摘要

晚期皮肤鳞状细胞癌(cSCC)是一种危及生命的疾病,在晚期有效和安全的治疗非常有限。GP-2250最近已被证明对癌细胞具有体外和体内的抗肿瘤作用。本研究旨在通过剂量发现评估、MTT细胞毒性试验、细胞迁移试验、BrdU增殖试验和FCM分析,探讨GP-2250对cSCC细胞株SCC13和A431的潜在抗肿瘤作用。我们的初步结果首次证明了GP-2250对cSCC细胞的抗肿瘤作用,增强细胞毒性,减缓癌细胞增殖,诱导细胞凋亡,减少肿瘤细胞迁移。进一步的研究评估GP-2250对cSCC细胞系的作用模式是必要的,以证明在体内研究的使用是合理的。

An In Vitro Pilot Study Investigating the Antineoplastic Effects of GP-2250 on Cutaneous Squamous Cell Carcinoma Cell Lines: Preliminary Results
Advanced cutaneous squamous cell carcinoma (cSCC) can be a life-threatening disease for which effective and safe treatment in advanced stages is very limited. GP-2250 has been recently proven to have—in vitro and in vivo—antineoplastic effects on cancer cells. This study aims to investigate the potential anti-neoplastic effects of GP-2250 on the cSCC cell lines SCC13 and A431 through dose finding assessments, MTT cytotoxicity assays, cell migration assays, BrdU proliferation assays and FCM analysis. Our preliminary results have shown for the first time evidence for anti-neoplastic effects of GP-2250 on cSCC cells, enhancing cytotoxicity, attenuating cancer cell proliferation, inducing apoptosis and reducing tumour cell migration. Further investigations evaluating the modes of action of GP-2250 on cSCC cell lines are warranted in order to justify the use in vivo studies.
