摘要:

背景:近年来的研究表明,中药栀子可能具有活化软骨细胞的功能,而京尼平苷是栀子中重要成分之一。
目的:观察京尼平苷对体外培养大鼠膝关节软骨细胞Ⅱ型胶原蛋白合成的影响。
方法:体外分离培养大鼠膝关节软骨细胞,分别应用25,50及100 mmol/L京尼平苷干预,并设置正常对照组。RT-PCR和Western blot法观察京尼平苷对各组细胞Ⅱ型胶原mRNA和蛋白表达的影响。
结果与结论:RT-PCR和Western blot法检测结果显示,与正常对照组相比,25,50及100 mmol/L京尼平苷干预可以明显促进Ⅱ型胶原mRNA及蛋白的表达(P < 0.01)。结果证实,京尼平苷可以促进大鼠膝关节软骨细胞Ⅱ型胶原蛋白的合成。

Abstract:

BACKGROUND: Chinese herb Cape Jasmine Fruit can activate the chondrocytes and geniposide is an important component in this herb.
OBJECTIVE: To investigate the effect of geniposide on collagen II synthesis in rat chondrocytes cultured in vitro.
METHODS: Rat chondrocytes were separated and cultured in vitro. The chondrocytes were then interfered with 25, 50 and 100 mmol/L geniposide. Normal control group was also set. Collagen II mRNA and protein expression was detected with semi-quantitative RT-PCR and western blot analysis, respectively.
RESULTS AND CONCLUSION: RT-PCR and western blot analysis results showed that, geniposide at 25, 50 and 100 mmol/L increased the collagen II mRNA and protein expression (P < 0.01). Geniposide can promote the synthesis of collagen II in rat chondrocytes cultured in vitro.
