Cohesin is essential for maintaining structural loops but less so for regulatory loops and transcription. Is cohesin actually required for the establishment of loops and transcriptional activation?🧵bit.ly/4hXremH

Happy to see our own @VarvaraParask representing blood cancer at @Fusion_Conf "Animal Models of Cancer"! Dont forget: Leukemia is a cancer and it has it's microenvironment 😀! Thanks @KevinHaigisLab & @SageJulien for inviting Varvara! #AifantisLab @NYUGSOM_Path #CancerResearch

#postdoc position available in my lab! Exciting opportunity to work on the role of #ncRNAs and #ChromatinArchitecture in #StemCells @IIT. This position is fully supported by the ECF fellowship from the @HumanTechnopole and will be based in Genova (Italy). nature.com/naturecareers/job…

New preprint from the lab! Led by @IMPRS_GS PhD students Shu Zhang and Nadine Ubelmesser and supported by @dr_barbieri_mar for modeling, we found selective dependency of enhancer-promoter loops on RNAPII using #MicroC. Our work assigns RNAPs with a clear role in #3Dgenome folding

A wonderful paper from the twitter-less Nefeli Slavi @LadyGlaucoma and the @drcarolmason lab, linking gene expression in the CMZ with the establishment of the binocular circuit and depth perception. biorxiv.org/content/10.1101/…

This collaborative study with my partner in crime (Matthias Stadtfeld) is the result of very hard-work and resilience of two amazing postdocs @AronsonBoaz and @LScourzic and help of many others, including @MDawlaty, Hynek Wichterle, @TommyVierbuchen and @artsinyc!

And yes our imprinting story is finally out at @Dev_Cell! It started as a "straightforward" mini-screen to identify the minimal control element that controls Dlk1-Dio3 imprinting maintenance in mESCs, but it surprised us in so many ways! See below: authors.elsevier.com/a/1d~FG…
