Triggering cell death in metastatic melanoma may pave the way for new cancer treatments | Harvard T.H. Chan School of Public Health
A Harvard Chan School study offers new ways to understand cancer and its vulnerabilities, and suggests that certain protein inhibitors could potentially be effective treatments for the disease.

Melanoma cells that spread to lymph nodes depend on FSP1 to survive, revealing a new metabolic vulnerability. New study in Nature by @mariopalma.bsky.social @ubellackerlab.bsky.social and colleagues shows that blocking FSP1 triggers ferroptosis and suppresses tumor growth in lymph node metastases.
