The BIGGEST impact you can have with 1 minute today ⏱️

Add your name to show NY is ready for a statewide biomedical institute.

CA’s CIRM & TX’s CPRIT proved it works—billions returned, jobs created, cures accelerated. Let’s do even better for New York.

🍾🧪The end of an era! Today we said so long to Dr. Troy Anderson. Troy was the very first person to join me in the Smeeton lab. He just defended his PhD and is off to start his postdoc next month. We will miss you Troy!! #proudPI @troy-anderson.bsky.social #zebrafish

Due to their aquatic environment, #zebrafish are perfect for small molecule drug screens. Many drugs have been repurposed for novel treatments such as COX inhibitors in leukemia & glucocorticoids in long QT syndrome. For more, read this Nature review ($): doi.org/10.1038/nrd4... #ZebrafishFunFacts 🧪
Figure taken from MacRae & Peterson (2015): How suitable are zebrafish for discovering human drugs? Although zebrafish enable in vivo studies on a large scale, questions remain about how relevant the findings are for drug discovery. Recent studies have begun to elucidate the degree of conservation between humans and zebrafish, which share 82% of disease-associated targets and a large number of drug metabolism pathways (as illustrated by the mass spectrometry of metabolic by-products). Zebrafish physiology is often well conserved (sometimes more so than rodent physiology); for example, cardiac electrophysiology (illustrative electrocardiogram (ECG) tracings from each organism are shown). Several compounds discovered in zebrafish screens have been shown to exhibit similar effects in rodent models and humans, including eight out of ten compounds tested by our groups. m/z, mass to charge ratio.

Some exciting news! NCBI has finished the annotation pipeline for our new #zebrafish reference sequence GRCz12tu:

This is a big step up in data depth and quality and should be super helpful going forward.

I think some people hear “grants” and think that without them, scientists and government workers just have less stuff to play with at work. But grants fund salaries for students, academics, researchers, and people who work in all areas of public service.

“Pausing” grants means people don’t eat.
White House pauses all federal grants, sparking confusion
The Trump administration has put a hold on all federal financial grants and loans, affecting tens of billions of dollars in payments.

Sox10 is required for systemic initiation of bone mineralization

Read this #OpenAccess Research Article by Stefani Gjorcheska, Lindsey Barske & co. @cincyresearch.bsky.social :
https://journals.biologists.com/dev/article/152/2/dev204357/365396/Sox10-is-required-for-systemic-initiation-of-bone
Figure 1 (A) Example images illustrating a major delay in initiation of bone mineralization in sox10 mutants between 3 and 7 dpf revealed by Alizarin Red staining. Some mineralization is present by 5 dpf but never achieves control levels before lethality at 8 dpf.
