Cow Tools!
We have lived alongside cows for nearly 10,000 years.
We breed them and exploit them
It is now, only now, that we have discovered THEY CAN USE TOOLS

🧬 Kinase Inhibitors can do more than block their targets!
A study by @cemm.oeaw.ac.at-@aithyra.bsky.social and #IRBBarcelona reveals that many inhibitors also trigger the degradation of the kinases, uncovering an overlooked mechanism with therapeutic potential.

Our preprint is out! We induced apoptosis in myeloma cells with BMP9 and did a whole genome KO screen to find regulators of apoptosis (and BMP-SMAD signaling). ID3 induced by SMAD activity inhibited TCF3 and induced apoptosis.
