This is not a HiC map! Ever wondered if multiple enhancers get activated simultaneously? We measured chromatin accessibility on thousands of molecules by nanopore to create genome-wide co-accessibility maps. Proud of @mathias-boulanger.bsky.social @kasitc.bsky.social Biology in the thread👇

kasitc.bsky.social@kasitc.bsky.social · 12mo ago

Activity of most genes is controlled by multiple enhancers, but is there activation coordinated? We leveraged Nanopore to identify a specific set of elements that are simultaneously accessible on the same DNA molecules and are coordinated in their activation. www.biorxiv.org/content/10.1...

How do enhancer-gene contacts relate to transcription activation? In mouse embryonic stem cells, a combo of STED, oligoFISH & RNA FISH shows that 3% of Dppa3 alleles transcribe. For these, enhancers and promoters come closer (panel E). Stumberger ... Leonhardt & Harz www.biorxiv.org/content/10.1...

How do non-coding variants in enhancers lead to disease? Happy to share our recent work, led by @ewholling.bsky.social, in which we discovered that poised chromatin sensitizes enhancers to aberrant activation by non-coding mutations, contributing to disease. www.biorxiv.org/content/10.1... 1/
