1/ 🎄 We got our Christmas present today: "Two distinct chromatin modules regulate proinflammatory gene expression" is now published @natcellbio.nature.com doi.org/10.1038/s415.... Our study introduces a scATAC-seq-based framework for genome-wide analysis of gene regulation features.

Happy to report that the Xenium system for spatial transcriptomics in the Single Cell Open Lab www.dkfz.de/en/single-ce... @dkfz.bsky.social was the first one worldwide to pass the mark of 100 runs according to @10xgenomics.bsky.social. And it keeps on running with another one, so stay tuned...

"In our view, it [hexanediol] should thus be avoided and not be used as evidence for the formation of an assembly via phase separation or the fluid-like nature of a condensate in vitro or in vivo." doi.org/10.1038/s414...

Glad that the preprint on identifying and characterizing rare tumor-reactive T cells in multiple myeloma & AML patients is out now doi.org/10.1101/2025.... Single-cell TCR and transcriptome profiling & immunopeptidomics revealed conserved programs and shared non-canonical antigens.

Liquid-liquid phase separation of HP1? Not in our mouse fibroblasts… This paper by the Fabian Erdel group offers a fresh perspective on how this can be reconciled with seemingly conflicting reports: The phase separation propensity of HP1 decreases from yeast → fly → mouse. doi.org/10.1038/s414...

1/ Spatial transcriptomics technologies are rapidly evolving. We compared five methods—Visium, RNAscope HiPlex, Molecular Cartography, Merscope, and Xenium—and developed technology-agnostic quality control metrics to guide their use: doi.org/10.1186/s130...

How do transcription compartments form — and does phase separation drive gene expression? I enjoyed discussing these questions with @akispapantonis.bsky.social a lot, and we put our thoughts together for @naturerevgenet.bsky.social, now out at rdcu.be/erP1u

From enhancer hijacking to ecDNA and onco-condensates – we review how changes in nuclear architecture drive oncogenic gene expression by disrupting enhancer–promoter communication. doi.org/10.1002/ijc..... Kudos to Isabelle Seufert, @claire-vrgs.bsky.social and Sina Wille 👏

A mechanism for maintaining and spreading H3K9me3 in heterochromatin from the Fejes Toth and Aravin labs that depends on the local H3K9me3 density: HP1 dimers recruit SetDB1 to chromatin by simultaneously binding H3K9me3 on histone H3 and auto-methylated SetDB1. www.biorxiv.org/content/10.1...

Fakten sind das Rückgrat unserer Demokratie Facts are the backbone of our democracy When facts are treated as opinions and replaced by rhetoric or propaganda, meaningful discourse suffers, threatening democracy and leaving it vulnerable to manipulation. www.openpetition.de/!ychtb

🧬 1/ Heterochromatin protein 1 (HP1) still surprises us after all these years: It simply sticks to chromatin when pericentric heterochromatin domains – the chromocenters – are activated in mouse fibroblasts and acts as a local rather than global repressor. New preprint: doi.org/10.1101/2024...

By definition, enhancers can activate from a distance. But with increased distance between enhancer and promoter, the activation drops. To study this systematically, we build a synthetic locus: www.cell.com/molecular-ce... 1/12
