The main project of my PhD 🧬🔬 is out: we developed single-cell lentiMPRA, a lentivirus-based method to measure enhancer activity and transcriptomes at single-cell resolution. We then applied sc-lentiMPRA to fully synthetic enhancers 🧩...

Today marks 4th anniversary of Russia's invasion of Ukraine. Russia is responsible for over 200,000 war crimes, killing over 15,000 civilians and displacing millions. My heart breaks for every Ukrainian. I continue attending rallies and donating hoping one day Ukraine will be free and safe.

Exciting to see it published! I had a lot of fun using AlphaGenome since the preprint. Congratulations!

Europe is stepping up, helping Ukraine for the right moral reasons and helping their mutual economies.

BMP signaling-dependent dorsal-to-ventral gradient of PAX3/7 transcriptional activity revealed by the P34::tk::LacZ reporter. Left: expression patterns of neural progenitor (NP) and interneuron (IN) TF markers in the developing spinal cord. Right: Immunostaining for β-galactosidase (β-gal; red/grey), GFP (blue/grey) and either OLIG3 (green/grey) or pSMAD1/5/9 (green/grey) on transverse sections of E9.0 (bottom) and E9.5 (top) P34::tk::LacZ; Pax3+/GFP spinal cords at brachial level. Black and white panels show magnified views of the boxed region.

How do pleiotropic TFs generate organized diversity in developing tissues? @spinalorga.bsky.social shows that PAX3 & PAX7 organize #SpinalCord by acting as both repressors & pioneer activators, regulated by #morphogens to ensure precise neural subtype specification @plosbiology.org 🧪 plos.io/4qumsla

Cracking the code of the non-coding genome via allele-specific genomics?
Can we link non-coding elements—like lncRNAs and enhancers—to their protein-coding target genes, and in doing so, connect overlapping non-coding disease variants to their protein-coding counterparts?

Promoter-proximal gatekeepers restrict pleiotropic enhancer inputs to achieve tissue specificity Developmental enhancers are central regulatory elements that can activate multiple genes, yet how they selectively regulate one gene over its neighbours remains unclear. Using the Drosophila twist E3 ...

Ever wondered what drives enhancer-promoter specificity? Why would an enhancer activate one gene rather than another neighboring one?

Loss of miR-9-2 Causes Cerebral Hemorrhage and Hydrocephalus by Widespread Disruption of Cell-Type-Specific Neurodevelopmental Gene Networks. MIR-9-2 is a broadly and highly expressed microRNA in the developing brain and is frequently deleted in 5q14.3 Microdeletion Syndrome, a rare but severe neurodevelopmental disorder. Despite this, litt...

#Neuroskyence students! We're brainstorming ways to support your development over this summer break, esp. given the changes in summer intern programs across our fields. What other opportunities would you like to see?

Some ideas: undergrad-focused webinars, self-paced courses, challenges, etc.

Standing with Ukraine in Seattle

I was touched by the great turnout in Seattle to support #Ukraine. Thank you to the organizers and @adamsmith.house.gov for your speech. We must continue arming Ukraine and defend democracy against Russian invasion. #StandWithUkraine 🇺🇦"

Since 2022, people around the world have stood in solidarity, joining rallies to support Ukraine and refusing to let russia silence the truth. They chose Ukraine’s side, united in the fight for freedom. Join in, speak up, #StandWithUkraine:

Your city might have separate events, like the one I'll be attending in Seattle, organized by the Ukrainian Association of Washington State

Global Events Where You Can Stand With Ukraine as Russia’s Full-Scale War Hits the Three-Year Mark Global events mark three years since Russia's invasion of Ukraine, showcasing solidarity and raising awareness for ongoing support and resilience.

As Russia's full-scale war hits the three-year mark, it's more important than ever to #StandWithUkraine. I encourage you to raise your voices for peace and justice by attending one of the events organized worldwide.

Negotiating with the murderous dictator Putin won't lead to anything. He needs to be forced to retreat from Ukraine.

I hope this hastens the fall of Putin's regime

Since Russia's invasion of Ukraine, almost 20,000 Ukrainian children have been kidnapped by Russia. DNA testing might be the only way to one day reconnect them with their families.

I'm sure the Russian government will deny everything similar to MH17 and countless wat crimes they commit in Ukraine.
