摘　　要：目的 研究转铁蛋白(Tf)修饰的姜黄素(Cur)脂质体(Lips)对口腔鳞状细胞癌细胞株HN4的影响。方法 制备Cur-Lips以及Tf-Cur-Lips;通过Cur体外释放实验以及大鼠体内药物代谢动力学实验,考察Cur-Lips及Tf-Cur-Lips对Cur体内外代谢的调节作用;用不同浓度的Cur、Cur-Lips及Tf-Cur-Lips溶液处理HN4细胞后,采用细胞计数试剂-8实验检测不同实验组对HN4细胞增殖的影响;实时荧光定量聚合酶链式反应技术检测凋亡相关基因P53和Fas表达水平变化,以探讨Tf修饰对Cur-Lips抑制HN4细胞增殖和凋亡的分子机制。结果 与Cur相比,Cur-Lips显著延长了Cur的代谢时间;Tf-Cur-Lips能进一步提高Cur的稳定性,延长Cur的代谢时间。与Cur及Cur-Lips相比,Tf-Cur-Lips能显著增强Cur对HN4细胞的增殖抑制,并上调凋亡相关基因P53和Fas的表达。结论 Tf-Cur-Lips相比于Cur和Cur-Lips,具有更强的抑制口腔鳞状细胞癌细胞株HN4增殖的作用。Objective This study aimed to investigate the effect of transferrin(Tf)-modified curcumin(Cur)-loaded liposomes(Lips)on the oral squamous cell carcinoma cell line HN4.Methods Cur-Lips and Tf-Cur-Lips were prepared,and their regulatory effects on the internal and external disposal of curcumin were investigated during Cur release in vitro and pharmacokinetics in vivo in rats.Then,HN4 cells were treated with Cur,Cur-Lips,and Tf-Cur-Lips at different concentrations successively,and cell counting kit-8 was used to detect the effects of different experimental groups on HN4 cell proliferation.Finally,the expression levels of apoptosis-related genes P53 and Fas and the molecular mechanism of transferrin modification on Cur-Lips inhibiting the proliferation and apoptosis of HN4 cells were investigated through real-time fluorescence quantitative polymerase chain reaction.Results Compared with Cur,Cur-Lips considerably prolonged metabolic time,and transferrin modification further improved the stability of Cur and prolonged the metabolic time of Cur-Lips.Compared with Cur and Cur-Lips,Tf-Cur-Lips markedly enhanced the inhibitory effect on the HN4 cell proliferation and up-regulated the expression of P53 and Fas.Conclusion Tf-Cur-Lips have a stronger inhibito‐ry effect on oral squamous cell carcinoma cell HN4 than Cur and Cur-Lips.
