Hello all, our lab is recruiting a PhD candidate to study how 3D genome folding impacts gene regulation in development. We're located at the Center for Integrative Genomics department of the University of Lausanne, Switzerland. Please email me if interested. #PhDPosition, #PhDOpportunity

We are thrilled that our study on the evolution of gene regulation in mammalian cerebellum development – led by @ioansarr.bsky.social, @marisepp.bsky.social and @tyamadat.bsky.social, in collaboration with @steinaerts.bsky.social – is now out in @ScienceMagazine! www.science.org/doi/10.1126/...

The evolution of gene regulation in mammalian cerebellum development
Gene regulatory changes are considered major drivers of evolutionary innovations, including the cerebellum’s expansion during human evolution, yet they remain largely unexplored. In this study, we com...

New paper on bioRxiv by YounJu So in our lab! She shows that while SMARCD paralogs compensate for each other during neurodevelopment, each still drives distinct gene expression programs, explaining selective vulnerability of these SWI/SNF subunits in brain disorders. www.biorxiv.org/content/10.6...

🪰 folks! I spoke to the Transmitter about FlyBase. As noted at flybase.org, bridge $ ran out and many staff were laid off. Good news is stopgap contributions will keep core FlyBase operations active. But community support remains essential. Please donate @FlyBase and share! 1/2 tinyurl.com/FlyBase

FlyBase secures funding for year, but future still uncertain
The FlyBase team’s fundraising efforts have proven successful in the short term, but restoration of its federal grant remains uncertain.

Connexin 41.8 governs timely haematopoietic stem and progenitor cell specification
Summary: Cx41.8 is necessary to launch the haemogenic program and induce HSPC formation at the correct time during zebrafish development via a ROS-Hif-Notch-Gata2b pathway.

The final chapter of my Pitx1 adventure is out! 1 simple question:”How do SVs that shorten enhancer-promoter distance affect limb development?” We find the impact on transcription, cell populations, epigenetics, and chromatin structure. A labour of joy with @guandrey.bsky.social & all co-authors.

Textbooks: “Enhancers are just a bunch of TFBSs” But how do they REALLY work? New paper with many contributors here @berkeleylab.lbl.gov, @anshulkundaje.bsky.social, @anusri.bsky.social A 🧵 (1/n) Free access link: rdcu.be/erD22
