As of 2026-09-15

Progesterone receptor shows approved-linked disease relevance led by endometriosis. 5 more disease programs remain visible in the same review block. 10 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P06401. Start with endometriosis, then reuse UniProt P06401 as the stable protein anchor across project notes and exports.

Disease program
endometriosis

Progesterone receptor shows approved-linked disease relevance led by endometriosis. 5 more disease programs remain visible in the same review block. 10 linked drugs remain visible in the same block.

Start review with endometriosis because it currently carries approved-linked support. Linked drugs include ASOPRISNIL, CYPROTERONE ACETATE, DANAZOL, LEVONORGESTREL. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
