  • 研究CGI甲基化,基因表达和基因功能之间的关系.
  • 为CGI分析和可视化提供一个集成的在线平台.

主要方法:

  • 开发了使用高性能计算的人类位置定义的CGI预测方法.
  • 创建了一个新的人类基因组注释和分析方法,以将CGI甲基化与基因表达和功能联系起来.
  • 将这些功能集成到PCGIMA在线平台中.

主要成果:

  • 人类位置定义的CGI预测方法有效地识别位置定义的CGI和短CpG小岛.
  • 标注和分析方法揭示了CGI甲基化,基因表达特异性和基因功能之间的全基因组连接.
  • PCGIMA提供了一个用户友好的平台,用于CGI预测,甲基化分析和可视化.

结论:

  • 开发的人类位置定义的CGI预测方法准确地定位了空头和位置敏感的CGI.
