I am truly honored to receive the Hilde Mangold Award from @gfeev.bsky.social!

Mangold’s classic transplantation experiments transformed developmental biology and our understanding of self-organization. I am grateful to be associated with this legacy!

Thank you for reaching out and for sharing about your son.

The biosensor that the team developed is a research tool that scientists use to study how variants (mutations) of a gene related to AS (Ube3a) work. It isn’t something used directly in patients or for diagnosis.

Warm regards,

SUN5 forms a regular protein lattice reinforcing the sperm head-tail junction Linker of nucleo- and cytoskeleton (LINC) complexes reside in the nuclear envelope, the double-membrane surrounding the nucleus, where they establish a physical bridge between nucleus and cytoplasm. L...

I am happy our recent study on the human sperm head-tail junction is now online. We find that SUN5 form an hexagonal lattice at the nuclear membrane, rationalising how mutations in SUN5 lead to infertility. Great work of @cryonas.bsky.social !

3′UTR shortening alleviates miRNA repression of mRNAs critical for muscle stem cell differentiation - The EMBO Journal Alternative polyadenylation (APA) modulates gene expression by altering 3′ untranslated region (3′UTR) length. Although 3′UTR lengthening typically accompanies cell differentiation, we unexpectedly ob...

Hong Cheng and collaborators show how alternative polyadenylation can facilitate muscle differentiation and regeneration: 3’UTR shortening of differentiation-gene mRNAs alleviates their repression by myomiR muscle-specific miRNAs

Here we compare the ultra-compact Calm1 promoter with the widely used hSyn promoter for targeting human neurons using AAV-mediated delivery. Our findings show that Calm1 is a promising alternative for neuronal gene delivery and in the future development of clinical interventions for brain disorders.

Small promoter, big potential🧬 We show that the ultra-compact Calm1 promoter efficiently targets human neurons in brain organoids and is a promising alternative to hSyn for AAV gene delivery.
