摘要: 目的 研究高脂间歇低氧诱发动脉粥样硬化形成的重要作用基因。方法 提取高脂组和高脂间歇低氧组动脉粥样硬化兔模型肝组织总RNA,用抑制性消减杂交技术,构建差异表达的cDNA消减文库,用反向Northern blot法鉴定存在差异表达的基因,对插入片段测序后进行blast的同源性搜索未知基因,定量RT- PCR验证。结果 获得的组蛋白脱乙酰基酶7(HDAC7)为未知功能新基因,在两组肝脏组织中表达存在显著差异。结论 HDAC7可能是高脂间歇低氧诱发动脉粥样硬化发生中发挥重要作用的新基因。

Abstract: Objective To investigate gene expression patterns of atherosclerosis (As) induced by intermittent hypoxia and hyperlipemia. Methods Isolation total mRNA of liver tissue from atherosclerosis rabbit model in hyperlipemia group and hyperlipemia with intermittent hypoxia group. Suppression subtractive hybridization was adopted to construct cDNA lib, and to identify differential expression by opposite Northern blot, after insertion element was sequenced blast analysis by quantitate RT-PCR. The expression of histone deacetylase 7 was obviously difference in two groups. Results MYL6 and HDAC7 were screened in cDNA lib. Conclusion The process of atherosclerosis induced by intermittent hypoxia is correlated to many genes. HDAC7 is a gene play new important role in AS.
