I'm excited to share the lab’s new paper on PDAC-associated cachexia on bioRxiv today, led by star postdoc @Nikita2106

Pancreatic cancer cachexia is mediated by PTHrP-driven disruption of adipose de novo lipogenesis

A 🧵 below, if you're interested...

An absolutely beautiful study in Nature Cancer by the Chio lab on a novel mechanism of adipose tissue wasting in pancreatic cancer.

Congrats to Christine, first author Jung Seung Nam, and the rest of the @Chiolaboratory!

Very happy to share our new paper in Nature Cancer. This project started with a simple question: what drives the early loss of adipose tissue during pancreatic cancer cachexia?

New paper out in @cellpressblue ! We found that reintroducing refined starch after weight loss activates the innate immune system through the complement pathway, while sugar has the opposite effect. With @eze_dantas , @davidludwigmd , CaraEbbeling, @CantleyLab , and team. 🧵
