As of 2026-09-1472 kDa type IV collagenase shows late clinical disease relevance led by breast cancer. 5 more disease programs remain visible in the same review block. 2 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P08253. Start with breast cancer, then reuse UniProt P08253 as the stable protein anchor across project notes and exports.
72 kDa type IV collagenase shows late clinical disease relevance led by breast cancer. 5 more disease programs remain visible in the same review block. 2 linked drugs remain visible in the same block.
Start review with breast cancer because it currently carries late clinical support. Linked drugs include MARIMASTAT, REBIMASTAT. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
