5-alpha-reductase turns testosterone into the more potent dihydrotestosterone inside the prostate; finasteride and dutasteride block it, and two large trials showed they cut prostate cancer diagnoses by about a quarter while raising concern about high-grade tumours. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
A membrane enzyme of the endoplasmic reticulum in prostate, genital skin and hair follicles; it is NADPH-dependent and genetic loss causes a disorder of sex development.
| Cancer | Prevalence | Measure | Note | Source |
|---|---|---|---|---|
| Prostate cancer | host% | Host enzyme in normal and malignant prostate; finasteride and dutasteride were tested for prevention, not as a tumour marker | cancer.gov |
