  缪清博士拥有化学和生物学双博士学位,曾有6年在中科院大连化学物理研究所从事材料化学工作经历。自1996年到美国后,缪清博士长期从事心血管疾病和肿瘤的发生、发展机制及生物治疗的研究。在耶鲁大学医学院博士后期间发现了一个重要的细胞受体蛋白NgBR (Nogo-B receptor),并领导威斯康辛医学院研究团队深入系统地研究了NgBR在血管发育及肿瘤发生、发展及治疗中生物学功能, 其中包括对表观基因的调控。

  缪清博士主要研究方向是1. 血管变异疾病: 脑海绵状血管瘤以及新生儿肺发育缺陷;2. 调控脂肪酸代谢和脂肪肝;3. 降低肿瘤抗药性的新治疗靶标;4. 纳米药物对表观基因的调控。作为课题负责人获得美国国立卫生院(NIH)R01,187.5万美元资助,以及承担多项美国心脏病协会,美国癌症协会及威斯康辛州乳腺癌及前列腺癌研究协会资助项目的研究。已发表SCI文章四十多篇,2项专利和3篇综述文章。

  报告摘要:

    Nogo-B receptor (NgBR) was identified as a receptor specific for Nogo-B. Our previous work has shown that Nogo-B and its receptor (NgBR) are essential for chemotaxis and morphogenesis of endothelial cells in vitro and intersomitic vessel formation via Akt pathway in zebrafish. Here, we further demonstrated the roles of NgBR in regulating vasculature development using tissue specific knockout mice. NgBR deficiency results in cerebrovascular malformation and other diseases, such as non-alcohol fatty liver diseases (NAFLD) and breast cancer. Cerebral cavernous malformations (CCMs) are one of major brain vascular malformation. Three genes such as CCM1, CCM2 and CCM3 are involved in the pathogenesis of CCMs. Our studies demonstrated that NgBR regulates the transcription of CCM1 and CCM2. NgBR deficiency is one of risk factors promoting the onset of CCM diseases. In the liver, NgBR deficiency promotes the hepatic lipogenesis and results in the NAFLD. In contrast, NgBR levels increase in the several cancers, such as estrogen receptor positive breast cancer and liver cancer. Our results demonstrated that high expression of NgBR increases the resistance of tumor cells to chemotherapy. In a word, we are using molecular cell biology approach and animal models to elucidate the roles of Nogo-B receptor in the pathogenesis of several diseases.
