、研究方向

1. 面向肿瘤精准诊疗的表观基因组学标志物开发

利用DNA甲基化测序及多组学分析,系统解析肺癌、胃癌、结直肠癌和乳腺癌等高发癌种的表观遗传图谱。通过大样本临床组织建模,鉴定肿瘤早期检测、溯源及侵袭性评估的甲基化标志物,推动液体活检与病理辅助诊断的临床转化。

2. 基于纳米孔测序的病原微生物快速识别及耐药性检测方法开发

利用纳米孔靶向测序及宏基因组测序,开发针对下呼吸道、骨关节、结核及免疫缺陷人群感染的病原鉴定与耐药检测方案。通过多中心队列验证,建立单管靶向测序流程,缩短诊断周期,为临床抗感染提供快速、精准的个体化用药依据。

3. RNA修饰单碱基分辨率定量测序技术的开发与临床应用

聚焦RNA表观转录组学,针对Ψ、m5C、m6A等修饰,开发具有自主产权的单碱基分辨率、全转录组定量测序新技术(如BID-seq)。通过化学标记或酶学转化,精准定位与定量RNA修饰,揭示其调控功能,为临床诊疗提供新靶点。

4. DNA表观遗传修饰精准检测与化学标记技术的开发

针对5mC、5hmC、5fC等DNA修饰,开发新一代超快速、超低起始量测序技术(如UMBS-seq)。通过选择性标记,实现微量样本(如cfDNA)的单碱基全基因组图谱的绘制,为液体活检提供更精准、更温和的检测技术。

5. 基于DNA甲基化单倍型的表观遗传调控机制研究与转化应用

以DNA甲基化单倍型(mHap)为核心,以生物信息学和人工智能为主要手段,系统解析肿瘤在发生、进展、转移及耐药等关键过程中的DNA甲基化分子特征与动态演变规律,致力于发现高灵敏度、高特异性的肿瘤标志物,并推动其临床转化应用。前期工作中,牵头定义了mHap数据格式规范,研发了mHapTools、mHapTk等解析工具及TRAmHap转录活性预测模型,并构建了mHapBrowser公共数据库,形成了从数据标准、算法工具到共享平台的完整分析体系。在此基础上,系统绘制了人体正常组织与实体肿瘤的甲基化单倍型块(MHB)参考图谱,证实了MHB具有显著的组织与癌型特异性,富集转录调控元件,并可独立于平均甲基化水平调控基因表达。未来将持续深化mHap在肿瘤早期诊断、动态监测与耐药预警中的转化研究,为精准肿瘤学提供新的表观遗传学工具。

6. 多模态融合与课程学习驱动的低丰度ctDNA测序读长智能识别方法研究

针对ctDNA低丰度信号稀释瓶颈,本项目拟建立单分子分辨率智能识别框架。通过构建多模态大模型,整合甲基化与末端基序特征实现无偏倚扫描,采用三阶段课程学习与Loss优化,提升极端不平衡下训练性能,实现超低负荷下高灵敏度检测,为癌症早筛提供新范式。

7. AI驱动的循环游离核酸多组学整合与液体活检智能解析平台的构建

围绕“AI+循环多组学”构建外周血游离核酸(cfDNA/cfRNA)智能解析体系,整合肿瘤、炎症、免疫微环境及组织损伤等多维信号,建立多层级液体活检分析框架。通过cfDNA-TCR-seq追踪抗原特异性T细胞应答,ctDNA-BERT/CancerPRIMER解析和预测肿瘤信号,DeepCF-Chromatin捕捉转录调控动态,cfSEER推断组织空间生态位,cfEvoClock推断ctDNA克隆的演化历史,为肿瘤无创早筛、分型及治疗动态监测提供技术支撑。
