Ultraviolet radiation (UVR) increases melanoma incidence. Here, the authors report that UVR-damaged dermal fibroblasts upregulate MMP1 to degrade collagen which inhibits melanoma invasion and that aged primary melanomas in skin with degraded collagen have a better prognosis, while new collagen synthesis restores invasion and leads to death.
