Can cells remember being starved, and does that memory change how they behave in the future? This fundamental biological question is investigated by the research project called "Total Recall". It's funded with 40 million NOK through the "Toppforskere" programme from the Research Council of Norway

🌟 Congratulations to my PhD student Patrizia Nothnagel! 🌟 Patrizia won the "SUMO" poster award at the 2025 EMBO workshop "SUMOylation: From Discovery to Translation" in La Grande-Motte, France. Her work has paid off, and I am proud of her.
I am delighted to share a publication in @natcomms.nature.com. IRX3, linked to obesity via the FTO locus, influences fat vs bone cell fate. It is the result of a wonderful collaboration between S. Dankel, G. Mellgren @unibergen.bsky.social and my lab @biovitenskap.bsky.social 🍾 👉 rdcu.be/ezA5o

Totipotent-like cells in early mouse embryos reorganize their genome via Z-DNA and Zscan4-driven interactions to form a “Z compartment” first supporting ZGA and later compartmentalisation to safeguard the totipotent-like state. Chromatin plasticity at its finest! www.biorxiv.org/content/10.1...
Z-DNA formation induces the totipotent-like state and primes Zscan4-dependent chromatin compartmentalization
A remarkable transition during murine development is the progression from the 1-cell embryo to the 2-cell stage, accompanied by the activation of a specific set of embryonic genes, epigenome reprogram...

We’re Hiring! I am seeking a Pos-doc Researcher in Molecular Biology and Epigenetics. Join our team @biovitenskap.bsky.social @uio.no to explore how SUMOylation regulates epigenetic fate, gene expression, 3D-genome and chromatin during adipogenesis, with implications for obesity and cancer research.
This study is a very elegant characterisation of the epigenetic and transcriptional divergence between white and beige adipocytes. Very useful to those studying the epigenetic mechanisms supporting cellular reprogramming. www.biorxiv.org/content/10.1...
Multimodal epigenetic and enhancer network remodeling shape the transcriptional landscape of beige adipocytes
Epigenetic regulation is a key determinant of adipocyte fate and function, conferring phenotypic plasticity to adipose tissue in response to metabolic and thermal challenges. To understand the spatiot...

Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.
Many workplaces have parties or team meals to celebrate the end of the working year, but some show true appreciation by cultivating group traditions. Nature asked group leaders to explain these, and how they thank colleagues for their hard work. #AcademicSky

Alongside secret Santas and seasonal parties, many laboratories develop traditions to show appreciation to colleagues — from sweets and mulled wine to quizzes and ice-skating trips.
