In a recent Nature paper, @djcalebc.bsky.social et al. explore how PIKfyve regulates lysosomal lipid recycling in PDAC. This opens up a therapeutic window: co-inhibition of PIKfyve and the KRAS–MAPK pathway leads to synthetic lethality & tumor regression. View it here >>> nature.com/articles/s41...

Targeting PIKfyve-driven lipid metabolism in pancreatic cancer - Nature
A study of human and mouse models of pancreatic cancer finds that inhibiting the lipid kinase PIKfyve interferes with the cancer’s lipid homeostasis, making it a potential target for drug development.

My team and I are at #AACR25 and have posters to discuss parts of the project (and some future directions) tomorrow! Rüya Pakkan will present on Tuesday AM Abstract #4158 Sec 13 board 8. I will present on Tuesday PM #5384 Sec 12 board 12. Come visit!

Yesterday, the House passed an FY25 budget bill that slashes funding to the Pancreatic Cancer Research Program by 57%. Research for pancreatic cancer is already woefully underfunded, and now the only program exclusively funding pancreatic cancer research is one step closer to devastating cuts.
