Human eggs must segregate their chromosomes with exquisite precision — yet errors rise with maternal age, causing miscarriage & infertility.
Our new article on @biorxivpreprint.bsky.social shows why chromosome cohesion fails in aging eggs & how to improve it.

Thank you www.humanreproduction.uzh.ch/en.html specially @cavazzalab.bsky.social for two days discussing the science, ethics and history of #HumanReproduction. An impressive and much needed multidisciplinary intiative.

@krauthammerlab.bsky.social @einwuerfe.bsky.social @alicemargaria.bsky.social

Many thanks to you, very exciting visit!

We enjoyed your Annual Lecture in Reproduction and your stimulating inputs to our interdisciplinary project!

Your visit reinforced our vision that such interdisciplinary discourse is essential when approaching reproductive medicine research!

🚨JOB ALERT🚨

FRIENDS PLEASE SPREAD and RT

We are building a small expert team within the @bokelab.bsky.social at @crg.eu @prbb.org to investigate fundamental questions in oocyte cell biology, focusing on how proteostasis regulation influences dormancy and fertility.

She Worked in a Harvard Lab to Reverse Aging, Until ICE Jailed Her (Gift Article) President Trump’s immigration crackdown ensnared Kseniia Petrova, a scientist who fled Russia after protesting its invasion of Ukraine. She fears arrest if she is deported there.

The Americans are doing to Kseniia what the Russians did to Brittney Griner for having 0.7 grams of cannabis oil. Except no one is coming to negotiate her freedom and Harvard is sitting on their hands. I am so ashamed. Please share this story.

Maternal ELL3 loss-of-function leads to oocyte aneuploidy and early miscarriage - Nature Structural & Molecular Biology The authors show that ELL3 maintains chromosomal ploidy by promoting spindle assembly and driving chromosome movement in oocytes. Deficiency of ELL3 results in oocyte aneuploidy and may lead to early ...

@bernhard-m.bsky.social and I wrote a commentary on a cool paper published on NSBM by the Lin lab.

The article is about a new ELL3ment in spindle assembly related to maternally inherited aneuploidy and infertility.

Embryonic Signatures of Intergenerational Inheritance across Paternal Environments and Genetic Backgrounds The paternal preconception environment has been implicated as a modulator of phenotypic traits and disease risk in F1 offspring. However, the prevalence and mechanisms of such intergenerational epigen...

📢 Preprint! How does the environment of a father before conception influence offspring?

Even more, how do paternal genetics & ages interact with exposures to affect F1 outcome?

We tested this systematically, with intriguing findings & some cautionary tales🧵...

Hello Bluesky community! What a better way to introduce myself and my research team than post our lab’s first paper freshly off press 🥳🍾

We reveal how tubulins regulate the stability of their mRNA via reversible sequestration of TTC5. Bravo A. Batiuk and all coauthors 👏🏻🥂

Hallo BS World!

I look forward sharing and discussing with you my science, interests, and curiosity.

In my lab, we study how cellular processes impact early embryogenesis, especially from right after fertilization until blastocyst formation.

We love live 🔬 to study 🐄 embryos.

Thanks for organising it, could you please add me?
