Descripción
AKR1C3, also known as 17β-hydroxysteroid dehydrogenase type 5, is a multifunctional enzyme involved in the metabolism of steroid hormones, prostaglandins, and xenobiotics. AKR1C3 converts androstenedione to testosterone and estrone to estradiol, playing a central role in androgen and estrogen biosynthesis. It also reduces prostaglandin D2 to PGF2α, influencing inflammation, immune responses, and cell proliferation. AKR1C3 is overexpressed in hormone-dependent cancers, such as prostate, breast, and endometrial cancers, where it promotes tumor growth by enhancing local androgen and estrogen production. Its ability to detoxify lipid peroxidation products like 4-HNE also confers resistance to oxidative stress and chemotherapy. AKR1C3 is emerging as a therapeutic target in cancer, particularly in castration-resistant prostate cancer, where it sustains androgen receptor signaling. In addition to cancer, AKR1C3 regulates neurosteroids and prostaglandin pathways, linking it to inflammation, neuroprotection, and metabolic diseases.

This gene encodes a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins. These enzymes catalyze the conversion of aldehydes and ketones to their corresponding alcohols by utilizing NADH and/or NADPH as cofactors. The enzymes display overlapping but distinct substrate specificity. This enzyme catalyzes the reduction of prostaglandin (PG) D2, PGH2 and phenanthrenequinone (PQ), and the oxidation of 9alpha, 11beta-PGF2 to PGD2. It may play an important role in the pathogenesis of allergic diseases such as asthma, and may also have a role in controlling cell growth and/or differentiation. This gene shares high sequence identity with three other gene members and is clustered with those three genes at chromosome 10p15-p14. Three transcript variants encoding different isoforms have been found for this gene.
