Lymph Node Environment Influences FSP1 Targeting and Ferroptosis in Melanoma and Lung Cancer
TL;DR Summary
The study reveals that the lymph node microenvironment promotes resistance to ferroptosis in metastasizing melanoma by downregulating GSH synthesis and upregulating FSP1, which localizes to lysosomes and provides a GPX4-independent protective mechanism. Oxygen levels and epigenetic regulation influence GPX4 stability and ferroptosis sensitivity, suggesting potential therapeutic strategies targeting FSP1 and GSH synthesis in LN metastases.
