This research investigates how melanoma switches between two gene states—one fast-growing and treatable, the other slow but highly invasive and responsible for brain metastases. By identifying genes that control this transition, the study aims to force melanoma into a more treatable form, improving therapeutic options and patient outcomes.

Breast cancer most often kills by spreading to the brain, where hormone therapies fail. This research reveals a signaling pathway that drives tumor growth in both pre- and postmenopausal settings. Identifying alternative activators of this pathway opens new therapeutic opportunities for deadly brain metastases.
