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...
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?

tRNA-overlapping long non-coding RNA loci repress codon-biased genes
Ahmed et al. define tRNA-overlapping lncRNAs (tROLs). tROLs in gene-dense regions interact between chromosomes and depend on each other’s transcription. tROL perturbations silence codon-biased genes i...

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...
A male-essential miRNA is key for avian sex chromosome dosage compensation - Nature
Birds have evolved a unique sex chromosome dosage compensation mechanism involving the male-biased microRNA (miR-2954), which is essential for male survival by regulating the expression of dosage-sens...

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

Silent X chromosome awakens with age
In aging female mice, genes on the second X chromosome become active again. This could be an explanation for sex differences in aging humans regarding disease.

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. 🧵👇

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!
