Single-cell activation screen identifies hepatic maturation regulators with zonal resolution The maturation of lineage-committed embryonic hepatocytes requires both the timed activation of metabolic gene regulatory networks (GRNs) and silencin…

Happy to see Atsuhiro Taguchi's work on genes involved in liver zonation published in Dev @cellpress.bsky.social. Kudos to all authors at @molgen.mpg.de #MeissnerLab #HniszLab. Grateful for the opportunity to help!

HDAC3 prevents enhancer hyperactivation to enable developmental transitions Dynamic gene regulation requires precise cooperation between transcription factors and chromatin modifiers at regulatory elements to achieve not only activation or repression, but also appropriate tra...

Genes are not On/Off switches. In a new preprint we show that HDAC3 is key to establish correct transcriptional dose in development. Gr8 work from N. Stamidis @ucph.bsky.social and collab. @jamiehackett.bsky.social @gregersenlab.bsky.social . Huge thx to all authors! www.biorxiv.org/content/10.1...

Excited for a major milestone in our efforts to map enhancers and interpret variants in the human genome:

The E2G Portal! e2g.stanford.edu

This collates our predictions of enhancer-gene regulatory interactions across >1,600 cell types and tissues.

Congratulations @julianeg.bsky.social ! Very happy for your grant and looking forward to seeing more cool stuff from your lab!

During Cassandra Extavour's visit to the MPIMG, I was honored to chair a session discussing how we can collectively improve diversity and inclusion in science.

As a next generation of scientist, it was truly inspiring and empowering.

Kudos to all the organizers that make it happen!

What controls condensate composition and function beyond binding stoichiometry? We show that condensate microenvironments play a key role, and can be probed by a micropeptide killswitch in live cells. www.nature.com/articles/s41... in @nature.com ‬ with @yaotianzhang.bsky.social Denes Hnisz & team.

Delighted to share a new preprint from the lab!

We identified zinc-finger associated domain (ZAD)-containing C2H2 zinc-finger proteins (ZAD-ZnFs) as insulator-binding proteins in Drosophila.

Check out this 🧵 from @eimearlagan.bsky.social on our new Molecular Cell @cp-molcell.bsky.social paper! We show how the H3K27M Oncohistone reprograms chromatin in DMG, creating a specific dependency on CBX4/PCGF4-containing forms of cPRC1 👇

Clonal tracing with somatic epimutations reveals dynamics of blood ageing - Nature The discovery that DNA methylation of different CpG sites can serve as digital barcodes of clonal identity led to the development of EPI-Clone, an algorithm that enables single-cell lineage tracing th...

Macromolecular interactions dictate Polycomb-mediated epigenetic repression The dynamic regulation of epigenetic states relies on complex macromolecular interactions. PRC2, the methyltransferase complex responsible for depositing H3K27me3, interacts with distinct accessory pr...

Happy to share the lab's latest publication from @eli-elder.bsky.social and team in @narjournal.bsky.social ! What happens when #DNAmethylation maintenance is transiently interrupted in mouse embryonic stem cells? Let's dive in (1/11). doi.org/10.1093/nar/...

1/ H3K27me3 mimicry has repeatedly emerged through evolution, but what's the physiological relevance?

We show that JARID2 and PALI1 mimic H3K27me3 to antagonise PRC2 in vivo and restrict the spread of Polycomb domains.
