Very happy to share our paper rdcu.be/eUImj out today in @natcellbio.nature.com 🎉🎉🎉 We uncover an unexpected role for endogenous Xist RNA in regulating X-linked genes that escape X-inactivation.

📣 Yesterday our study uncovering the ancestry bias in gene annotations was finally published in @natcomms.nature.com! www.nature.com/articles/s41... If you work in human genetics or transcriptomics, do not miss our tweetorial!👇 @guigolab.bsky.social @bsc-cns.bsky.social @crg.eu

Giving a seminar today @ethz.ch on our new X-reactivation findings during aging—back at the institute where I started my PhD 10 years ago. Can’t wait to see some familiar faces!

📣 SAVE THE DATE Next X-inactivation meeting in Sapporo, Japan, 19-23 October 2026. Visit x-inactivation-meeting.org to join our mailing list. 🧬 speakers @dandergassen.bsky.social @marnieblewitt.bsky.social @heard65.bsky.social @crougeulle.bsky.social @sexchrlab.bsky.social @zhouqi1982.bsky.social

New paper from the lab: we’re using long-read sequencing to disentangle isoform complexity at allele-specific loci 🧬💡 Here, we combine the PacBio Iso-Seq workflow with the established WhatsHap phasing approach to assign long reads to the correct allele in polymorphic F1 mouse hybrids.

Cracking the code of the non-coding genome via allele-specific genomics? Can we link non-coding elements—like lncRNAs and enhancers—to their protein-coding target genes, and in doing so, connect overlapping non-coding disease variants to their protein-coding counterparts?

📢 Paper Alert: tinyurl.com/yzy2d864. We characterized tRNA-overlapping lncRNA loci = tROLs! tROL perturbations silence codon-biased genes in inter-chromosomal proximity. tROLs bridge the non-coding and coding genomes. @sickkidsto.bsky.social @uoftpress.bsky.social

Our study on a male-essential microRNA and the evolution of other dosage compensation mechanisms in birds is now out in Nature! www.nature.com/articles/s41...

🗞️Our June issue is live!📷 This month, we're featuring work on editing epigenetic age, somatic mutation, senescence, Alzheimer’s biomarkers and much more. Read it all here: nature.com/nataging/vol...

We are so happy to be on the cover @sarahhoelzl.bsky.social 🎉 The cover depicts the Three Fates, who manipulate the threads of life and death. The Fates are shown as three older women, unraveling the threads of the inactive X chromosome during aging. www.nature.com/nataging/vol...

Why do women experience aging-related diseases differently than men? A new study shows that with age, genes on the inactive X chromosome can reactivate – potentially influencing conditions like #dementia and #autoimmunity: go.tum.de/987255 #genetics #aging 📷 @dandergassen.bsky.social

We're excited to publish our latest study led by Bryony Leeke @bryonyleeke.bsky.social and Wazeer Varsally, now out in @nature.com 🍾This study focusses on the epigenome of marsupial embryos 🦘 mapping DNA methylation in embryo development to specific embryo events www.nature.com/articles/s41... 🧵

Our new contribution to the quest to find causal GWAS genes! Sam Ghatan from my lab at @nygenome.org led a systematic comparison of eQTLs and CRISPRi+scRNA-seq screens. TL;DR: they provide highly complementary insights, with ortogonal pros and cons. 🧵👇 www.biorxiv.org/content/10.1...

Do you work in 💫human genetics💫? Have you ever worried about what’s inside your gene annotation GTF⁉️ WELL, YOU SHOULD! 😱 Especially when studying a genetically diverse 🌍 cohort! 🔴We discover that gene annotations are European-biased 👉 impacting downstream analyses! Don't miss this thread🧵⬇️ 1/13

I’m incredibly proud to share the results of our lab’s first project, leading to the exciting discovery – Aging promotes reactivation of the Barr body at distal chromosome regions – now published in @nataging.nature.com! 🔗 tinyurl.com/3jkzzy7d

Online now!✨RESEARCH: @sarahhoelzl.bsky.social et al demonstrate that aging promotes reactivation of the inactive X chromosome in mice, and catalog escape genes using multi-omics @dandergassen.bsky.social www.nature.com/articles/s43... rdcu.be/ekm0I

Excited to share our lab’s first review, focusing on RNA localization! #RNA #RNAlocalization genomebiology.biomedcentral.com/articles/10....

I am super proud to share the first Andergassen Lab preprint! Here, we introduce a new framework to decode the non-coding genome, led by the outstanding work of @hasenbeint.bsky.social and co-authors Sarah Hölzl, Stefan Engelhardt @tum.de👇🧵
