文题释义:
多西紫杉醇:是以紫杉树中的化学物质为基础而合成出来的一种药物。药物作用机制与紫杉醇相似,即抑制微管的解聚,抑制细胞分裂。适用于局部晚期非小细胞性肺癌或转移性乳腺癌的治疗。
间充质干细胞:是干细胞家族的重要成员,来源于发育早期的中胚层和外胚层,属于多能干细胞,间充质干细胞最初在骨髓中发现,因其具有多向分化潜能、造血支持和促进干细胞植入、免疫调控和自我复制等特点而日益受到人们的关注。
摘要
背景:
多西紫杉醇为细胞周期特异性抗肿瘤药,单药抗肿瘤具有较好的缓解率,但对于化疗相对不敏感的肿瘤,多西紫杉醇单一化疗有效率较低。研究报道,利用骨髓间充质干细胞可以提高靶向药物局部富集肿瘤的能力。
目的:验证多西紫杉醇及骨髓间充质干细胞联合干预人肝癌细胞株SMMC-7721的作用。
方法:体外培养骨髓间充质干细胞,选取对数生长的SMMC-7721肝癌细胞,将其随机分为空白组,骨髓间充质干细胞组及联合组(多西紫杉醇与骨髓间充质干细胞联合)。采用流式细胞技术检测肝癌SMMC-7721细胞的周期变化;利用MTT法检测肝癌SMMC-7721细胞的生长率;采用聚合酶链法及免疫印迹法检测抑癌基因PTEN、p53的mRNA及蛋白表达情况。
结果与结论:①流式细胞技术检测显示:多西紫杉醇及骨髓间充质干细胞联合干预可以抑制肝癌SMMC-7721细胞增殖,与空白组比较,骨髓间充质干细胞组及联合组处于G0/G1期的细胞明显增多;②MTT检测显示:干预48 h后,与空白组比较,骨髓间充质干细胞组肝癌SMMC-7721细胞的生长率得到抑制,与骨髓间充质干细胞组比较,联合组肝癌SMMC-7721细胞的生长率得到显著抑制(P < 0.05);③RT-PCR检测显示:抑癌基因PTEN、p53的mRNA表达量在联合组明显高于空白组及骨髓间充质干细胞组;④Western blot检测显示:与其他2组比较,联合组明显上调抑癌基因PTEN、p53的蛋白表达量(P < 0.05);⑤结果提示,骨髓间充质干细胞能够抑制体外培养的肝癌SMMC-7721细胞的生长,联合多西紫杉醇干预后,肝癌SMMC-7721细胞的生长率可以得到显著抑制。

Abstract:

BACKGROUND: Docetaxel, a cell cycle specific anti-tumor drug, is a drug that is used primarily for treating breast cancer; however, its efficacy is low when used for treatment of cancer not sensitive to radiotherapy. Bone marrow mesenchymal stem cells have been shown to strengthen the effects of tumor-specific targeting chemotherapy drugs.
OBJECTIVE: To investigate the effects of docetaxel combined with bone marrow mesenchymal stem cells (BMSCs) on human hepatoma cell line SMMC-7721.
METHODS: BMSC cells were cultured in vitro. The logarithmic growth of SMMC-7721 hepatoma cells were randomly divided into blank control group, BMSCs group and combined treatment group (combined treatment of BMSCs and docetaxel). SMMC-7721 cell cycle was detected using flow cytometry. Cell growth rate of SMMC-7721 was determined by MTT assay. mRNA and protein expressions of tumor suppressor genes PTEN and p53 were detected by reverse transcription polymerase chain reaction and western blot assay.
RESULTS AND CONCLUSION: Combined treatment of docetaxel and BMSCs inhibited SMMC-7721 cell proliferation. Compared with the blank control group, the number of cells at the G0/G1 phase was significantly increased in BMSCs group and combined treatment group. The cell growth rate of SMMC-7721 was significantly inhibited in BMSCs group compared with the blank control group, and that was further inhibited in combined treatment group (P < 0.05). mRNA and protein expression of PTEN and p53 were significantly increased in combined treatment group compared with BMSCs group and blank control group (P < 0.05). Our results suggest that BMSCs inhibit the growth of SMMC-7721 cells, and combined use of docetaxel and BMSCs strengthens the antitumor effect of BMSCs.
