New paper from @zhixingchen2.bsky.social's lab!

It turns out that, in addition to its very low phototoxicity, PKmito Deep Red (PKMDR) directly reports on mitochondrial membrane potential (MMP) in live cells through its lifetime!

🔎 What are the consequences of hypermetabolism in human motor neurons?

Our new study from the @htyynismaa.bsky.social lab is out!

Using human iPSC-derived motor neurons, we show that increased energy demand drives key metabolic trade-offs.

Hypermetabolism results in the redistribution of acetyl-CoA usage, reduced histone acetylation, and potential vulnerabilities of motor neurons via altered maintenance of acetylcholine

Our latest now published in @natcomms.nature.com, where we found a new role for mitochondrial programming of SC-β cell fate through PPARα.

We're excited for the potential to target mitochondria to improve SC-islets to treat #T1D!
