In new #pancreascancer research, @muzumdarlab.bsky.social et al. find that the pre-existing molecular state of a #PDAC cell exerts greater influence over how a #KRAS mutation behaves than the identity of the mutation itself. medicine.yale.edu/cancer/publi... @molecularomics.bsky.social

How Cell State Shapes KRAS Mutation Effects in Pancreatic Cancer
This study shows that in pancreatic cancer cells, a cell's baseline state—not which KRAS mutation it carries—drives its molecular behavior.

With the recent FDA approval of #daraxonrasib for patients with #pancreaticcancer, there is a lot of excitement among patients and clinicians. Dr. Alexander Jordan: "The results of the trial were exciting because daraxonrasib almost doubled overall survival and risk of death ⬇️ by 60%."

We’re starting to understand something important about diet and pancreatic cancer: it’s not just how much fat we eat, it’s the types of fats in our diet. In preclinical models, some fats were linked to faster tumor growth, while others helped slow it down by making cancer cells more vulnerable.
