First preprint from the lab 🚨. How can enhancers regulate target promoters across vast genomic distances, and what is the role of cohesin loop extrusion in the process?. (1).

CTCF, just like any transcription factor, binds its target sites on and off. Turns out considering this dynamic is essential to explain chromosome folding patterns from Hi-C and microscopy, and how they rearrange upon tampering with cohesin. What an exciting manuscript! 👏.

19) This was a heroic effort by graduate student.@KarissaLHansen, who created more engineered cell lines than we can count with the help of genome editor extraordinaire Annie Adachi, and many wonderful collaborators in our lab and in @deWit, @Geoff & @RobertBlelloch groups.

(18) How does the SRR2 work to boost the effect of distal enhancers? Condensate biophysics? Unknown looping factors? 🤷. How can we hunt for similar elements across the genome & across cell types? 🧪🧬❓. We would love to know – check out the paper for some discussion.

(17) So it’s not that complicated in the end:. If you rely on an enhancer, you will need cohesin extrusion beyond ~18kb. UNLESS you have a promoter-proximal regulatory element that can synergize with your distal enhancer – which happens independently of cohesin.

(16) Why? Quite simply, you have now removed the two redundant axes that support long-range enhancer action at Sox2.
