A 3D map of the human genome at kilobase resolution reveals
2014年12月18日 · We use in situ Hi-C to probe the 3D architecture of genomes, constructing haploid and diploid maps of nine cell types. The densest, in human lymphoblastoid cells, contains 4.9 billion contacts, achieving 1 kb resolution. We find that genomes are partitioned into contact domains (median length, 185 k …
Hi-C 测序技术(图解详解) - 知乎 - 知乎专栏
Hi-C 技术源于基因组捕获技术(Chromosome conformation capture, 3C),是分析染色质三维空间结构的一种测序方法,用于研究三维基因组。 什么是三维基因组? 用途: 1、甲醛固定. 先加入甲醛将基因组中参与染色质互作作用的蛋白质凝固。 一般将活体样本在室温用 1-3%的甲醛处理 10-30min,但是此步骤会减少限制内切酶对DNA序列的消化效率,需要严格控制。 2、酶切序列. 用限制性内切酶切割基因组,打断后的片段大小会影响测序分辨率,一般有两种酶可供选 …

单细胞Hi-C分析工具Higashi——数据的降维与插补 - 知乎
2024年4月18日 · Higashi是一种基于超图的表示学习算法,可以结合单个细胞间的潜在相关性来增强接触图的整体插补方法。 这一方法将Hi-C接触矩阵转换为超图,并将contact信息和bin信息分别作为图的边与节点进行保存,并利用Hyper-SAGNN架构进行预测,被证明可以有效的对稀疏scHi-C矩阵进行插补。 Hyper-SAGNN是一种基于self-attention机制的图神经网络,可以有效完成节点分类和超边预测等任务,对大小可变的异质性超边有很好的预测性能,因此较为适合scHi-C数 …
