Stromal lipid species dictate melanoma metastasis and tropism 24 April 2025
Gurung et al. show that young
subcutaneous adipocytes provide lipids
and phosphatidylcholine to melanoma
cells, which activates PI3K-AKT,
OXPHOS, and oxidative stress. High
OXPHOS reduces metastatic burden and
associates with lung tropism. Conversely,
aged subcutaneous adipocytes provide
ceramides to melanoma cells, which
activates S1P-STAT3-IL-6 signaling,
increasing total metastatic burden and
liver metastasis.
A microenvironment-inspired synthetic three-dimensional model for pancreatic ductal adenocarcinoma organoids 25 October 2024
Below et al. describe a fully synthetic hydrogel extracellular matrix designed to elicit key phenotypic traits of the pancreatic environment in culture.
