The study also investigated the association between MMP expression, clinicopathological variables, BRAF V600 mutation status, and overall survival, and authors reported that primary NM tumors exhibited significantly higher expression levels of MMP-1, MMP-2, and MMP-13 compared to dysplastic nevi, and higher MMP-1 expression was associated with worse clinical outcomes, suggesting its potential as an independent prognostic marker. Here, MMP1 is linked to dysplastic nevus.
