Abstract

Aldo-Keto-Reductase 1C3 (type 5 17β-hydroxysteroid dehydrogenase (HSD)/prostaglandin (PG) F synthase) is the only 17β-HSD that is not a short-chain dehydrogenase/reductase. By acting as a 17-ketosteroid reductase, AKR1C3 produces potent androgens in peripheral tissues which activate the androgen receptor (AR) or act as substrates for aromatase. AKR1C3 is implicated in the production of androgens in castration-resistant prostate cancer (CRPC) and polycystic ovarian syndrome; and is implicated in the production of aromatase substrates in breast cancer. By acting as an 11-ketoprostaglandin reductase, AKR1C3 generates 11β-PGF to activate the FP receptor and deprives peroxisome proliferator activator receptorγ of its putative PGJ ligands. These growth stimulatory signals implicate AKR1C3 in non-hormonal dependent malignancies e.g. acute myeloid leukemia (AML). AKR1C3 moonlights by acting as a co-activator of the AR and stabilizes ubiquitin ligases. AKR1C3 inhibitors have been used clinically for CRPC and AML and can be used to probe its pluripotency.

摘要

醛酮还原酶 1C3(类型 5 17β-羟甾类脱氢酶(HSD)/前列腺素(PG)F 合酶)是唯一不是短链脱氢酶/还原酶的 17β-HSD。AKR1C3 作为 17-酮甾体还原酶,在周围组织中产生有效的雄激素,这些雄激素激活雄激素受体(AR)或作为芳香酶的底物。AKR1C3 参与去势抵抗性前列腺癌(CRPC)和多囊卵巢综合征中的雄激素产生;并参与乳腺癌中芳香酶底物的产生。AKR1C3 作为 11-酮前列腺素还原酶,生成 11β-PGF 以激活 FP 受体并剥夺过氧化物酶体增殖物激活受体γ的潜在 PGJ 配体。这些生长刺激信号暗示 AKR1C3 参与非激素依赖性恶性肿瘤,例如急性髓细胞性白血病(AML)。AKR1C3 兼职作为 AR 的共激活剂,并稳定泛素连接酶。AKR1C3 抑制剂已在临床上用于 CRPC 和 AML,可用于探索其多能性。
