- Reposted by Jakub Harnos labTogether with @harnoslab.bsky.social, we compiled what is known about direct interactions of Wnt and Notch components, and advanced the testable framework of how the crosstalk could allow for a more polarized cellular response to one pathway or the other.
- Why do we lose so much talent in academia? Let’s talk about it – openly, together, responsibly. NEXT TUESDAY AT 5:30 PM. PI Forum Brno #7 | Feb 3 @ CEITEC MU For all PIs, PhDs & researchers in Brno. Chaired by @fabianlab.bsky.social
- New Paper Alert! 1982: WNT discovered 1990s: NOTCH enters the stage 2000s: “Let’s study pathways separately.” 2025: “Actually, they talk to each other.” Welcome to the era of WNT-NOTCH crosstalk Great collaboration with Mašek lab (CZ) and G. Collu (US) royalsocietypublishing.org/rsob/article...
- When you urgently need the restroom but get lost in a Xenopus development poster instead… 🐸🧠 Thanks to my lab heroes Lorena & Douglas for representing the #DaysOfOpenDoors at Masaryk University #frogpower #MUNI
- 🧪🐸 PhD position open in the Harnos Lab (Masaryk University, Brno)! We study cell migration, WNT/PCP signaling, mitochondria & energy in Xenopus. Start: June 2026 (flexible) Apply by Feb 28, 2026 📩 harnos@sci.muni.cz #PhDposition #CellBiology #Mitochondria #Xenopus #WNT #PCP
- Just published a #BehindThePaper blog post about our new paper on PRICKLE3 and WNT/PCP signalling! 🧬 Check out the story behind the science and what we learned along the way 👇 communities.springernature.com/posts/behind...
- 🔥 New paper out! PRICKLE3 is not just another PRICKLE. It stabilizes VANGL, blocks CK1ε phosphorylation, suppresses RNF43, and rewires WNT/PCP signaling across species. Big mechanism. Big fun. 🐸🔥 www.nature.com/articles/s42...
- With @fabianlab.bsky.social — first author and last author in their natural habitats. #IKEA_Biology #SameOffice_SameChallenges #Pat&Mat

- Milé @msmtcr, když příště nebude sedět JEDNO číslo v Letter of Intent s hlavním projektem a celý projekt je kvůli tomu AUTOMATICKY vyřazen bez jakéhokoli upozornění, stačil by nám jeden krátký email k opravě. Místo toho: žádné review, a měsíce či roky práce v pr... myslím pryč.
- Merry Christmas from the Harnoš Lab 🎄🐸 See you in an exciting 2026! ✨
- New paper out in Sci Rep 🎉 Xenopus + azoles + developmental biology 🐸 A great collaboration with Veterinary University Brno. Read it here: pubmed.ncbi.nlm.nih.gov/41350377/
- 🔥 BIG NEWS! 🔥 Thrilled to share that I have been selected as one of the MUNI Junior Star 2026 awardees! ⭐️ Huge congratulations to all fellow awardees — and thank you, MUNI, for this incredible opportunity! 🙌 Let’s make science shine. 💫 #MUNIJuniorStar #Science #Research #ProudMoment

- Just wrapped up my first-ever poster presentation in BOTH English & Spanish 🎉 A truly fantastic experience! Learned that it’s not the poster itself that matters, but how we speak about science 🧪✨ Viva México! 🇲🇽
- 🇲🇽 Hola, buenos días from México! The VI Neurobiological Conference has just kicked off. Excited to step out of my comfort zone and represent not only our lab at Masaryk University, not only Brno, not only Czechia… but maybe even Europe! 🌍 Greetings from the heart of wild & central Mexico!🧠
- Today I start the first lecture of my course Developmental defects (Bi1152en) at Masaryk University 🎓 My favorite part: to show how scientists in Mexico 🇲🇽 in 18–19th century were sometimes ahead of European colleagues, who were the “flagship” of science at that time. @jbwallingford.bsky.social
