摘要/Abstract

摘要： 目的: 探讨放射线对成骨细胞系MC3T3-E1细胞增殖及TGF-β₁和Smad3/P-Smad3表达的影响。方法: 以小鼠胚胎成骨细胞系MC3T3-E1为研究对象,4MV直线加速器为放射源,给予单一剂量8Gy照射。照射后以CCK-8检测成骨细胞增殖情况,通过荧光定量PCR和Western免疫印迹分别检测TGF-β₁、Smad3基因和蛋白的表达,并分别用2^-ΔΔct法及光密度分析法分析基因及蛋白的表达水平。采用SPSS 13.0 软件包对数据进行统计学分析。结果: 单次8Gy剂量照射的细胞组与对照组相比,生长速度明显减慢;Smad3及TGF-β₁基因在照射后0.5 h,1 h组与对照组无显著差异（P>0.05）,照射后1.5 h组Smad3及TGF-β₁基因表达量与对照组存在显著差异（P<0.05）;P-Smad3、TGF-β₁蛋白表达在第1天明显上调;第3天、第5天照射组与对照组差异逐渐减小。8Gy照射后第1天,P-Smad3蛋白表达量最高,TGF-β₁蛋白表达量第3天最高。结论: 8Gy照射剂量可抑制MC3T3-E1细胞增殖,短时间内上调TGF-β₁和Smad3/P-Smad3在基因及蛋白水平的表达。

Abstract: PURPOSE: To investigate the effects of radiation on cell proliferation and expression of TGF-β₁ and Smad3/P-Smad3 in MC3T3-E1 cells. METHODS: The mouse embryos ossification cell line MC3T3-E1 was used, which was given a single dose of 8 Gy by 4MV linear accelerator. Cell proliferation after irradiation was detected by CCK-8, real-time PCR and Western blot, respectively. Gene and protein expression of TGF-β₁, Smad3 was detected by 2^-ΔΔct and densitometric analysis were used to analyze the expression level of genes and proteins, respectively. SPSS 13.0 software package was used for statistical analysis. RESULTS: After irradiation of 8 Gy, cell growth slowed significantly compared with the control group; the gene expression of Smad3 and TGF-β₁ had no significant change after irradiation for 0.5 h and 1 h (P>0.05), until 1.5 h (P<0.05); the protein expression of P-Smad3 and TGF-β₁ raised obviously on the first day. The difference between exposure group and control group gradually decreased on day 3 and 5. The protein expression of TGF-β₁ and P-Smad3 reached peak on the first and third day, respectively. CONCLUSIONS: 8 Gy dose irradiation inhibits cell proliferation and increases the expression of TGF-β₁ and Smad3/P-Smad3 on gene and protein level.
