We then introduce a score that quantifies local chromatin accessibility in tumor relative to blood cells and show that this metric can be useful for prioritizing marker regions with higher chances of being ...
Heterochromatin has been associated with several functions, from gene regulation to the protection of chromosome integrity; some of these roles can be attributed to the dense packing of DNA, which makes it less accessible to protein factors that usually bind DNA or its associated factors. For example, naked double-stranded DNA ends would usually be interpreted by the cell as … WebSep 8, 2024 · These noncoding regions are located in accessible chromatin regions (ACRs), which allow DNA-binding proteins and transcription factors to bind their target sequences. Such regions are thought to be enriched for cis -regulatory elements and were found to be good candidate regions for narrowing down functional sequences in maize ( …
WebMay 28, 2024 · Open chromatin regions (OCRs) are special regions of the human genome that can be accessed by DNA regulatory elements. Several studies have reported that a series of OCRs are associated with mechanisms involved in human diseases, such as cancers.
