摘要: 目的 检测与探讨内皮素-1及其受体拮抗剂对肝星状细胞(HSC-T6)细胞Ⅰ型胶原mRNA表达的作用和影响机制。方法 采用反转录聚合酶链反应法(reverse transcription-polymerase chain reaction,RT-PCR),进行半定量分析。结果 与空白对照组相比,ET-1组和ET-1+BQ-123组Ⅰ型胶原mRNA的表达显著升高(0.706±0.027、0.724±0.059比0.400±0.047,P<0.05);与ET-1组相比,ET-1+BQ-788组和ET-1+BQ-123+BQ-788组Ⅰ型胶原mRNA的表达显著降低(0.427±0.131、0.382±0.022比0.706±0.027,P<0.05)。结论 ET-1使HSC-T6细胞Ⅰ型胶原mRNA的表达明显升高,选择性ETB受体拮抗剂BQ-788能抑制ET-1引起的Ⅰ型胶原mRNA的高表达,而选择性ETA受体拮抗剂BQ-123则对其无明显作用。

Abstract: Objective To study the effects of endothelin-1 and its receptor antagonists on the expression of collagen-1 mRNA in HSC-T6 cells. Methods RT-PCR analysis was used in the research. Results The expression of collagen-1 mRNA in ET-1 and ET-1+BQ-123 group was significantly higher than that of control group (0.706±0.027 and 0.724±0.059 vs 0.400±0.047, P<0.05). The expression in ET-1+BQ-788 group and ET-1+BQ-123+BQ-788 group was significantly lower than ET-1 group (0.427±0.131 and 0.382±0.022 vs 0.706±0.027, P<0.05). Conclusion ET-1 can induce high expression of collagen-1 mRNA in HSC. BQ-788, and the selective ETB receptor antagonist, can inhibit high expression of collagen-1 mRNA in HSC-T6 induced by ET-1.
