在不同的CCC测定和细胞/组织类型中提供一致的输出格式.

主要方法:

多种CCC测定类型 (Hi-C,CHiC) 的整合.
开发一个复杂的计算管道用于数据处理和分析.
在类似于BED的格式中生成协调的色素相互作用数据.

主要成果:

CHARMER成功地处理CCC数据以产生统计学上显著的染色体相互作用.
该管道协调了各种细胞/组织类型和CCC测定中的相互作用数据.
输出数据是可查询的,并且采用一致的BED-like格式.

结论:

CHARMER为分析CCC数据提供了有价值的工具,解决了当前存储库中的局限性.
该管道增强了CCC数据对下游遗传和基因组研究的实用性.
统一的数据将通过FILER数据库访问.

Chromatin Immunoprecipitation- ChIP

Chromatin Immunoprecipitation- ChIP

Chromatin immunoprecipitation, or ChIP, is an antibody-based technique used to identify sites on DNA that bind to transcription factors of interest or histone proteins. It also helps determine the type of histone modifications such as acetylation, phosphorylation, or methylation.
Types of ChIP
ChIP can be divided into two types - X-ChIP and N-ChIP. X-ChIP involves in vivo cross-linking of histones and regulatory proteins to DNA, fragmenting the DNA by sonication, and isolating the protein-DNA...
