Abstract

Aldo-Keto-Reductase 1C3 (type 5 17β-hydroxysteroid dehydrogenase (HSD)/prostaglandin (PG) F 2α 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 2α to activate the FP receptor and deprives peroxisome proliferator activator receptorγ of its putative PGJ 2 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.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Other prostaglandin synthases in the same family as PTGES3 have been implicated in the production of androgens.

    “other prostaglandin synthases in the same family as PTGES3 have been implicated in the production of androgens48,49.”

    From Genome-scale CRISPR screens identify PTGES3 as a direct modulator of androgen receptor function in advanced prostate cancer (2025) · cites this paper as [48]

    The Prostaglandin biosynthesis section identifies AKR1C3 as a prostaglandin F synthase, and the Steroid biosynthesis section says it converts androgen precursors to testosterone and dihydrotestosterone. The paper does not identify AKR1C3 as being in the same family as PTGES3, so that part of the claim is unsupported. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • PTGES3 protein is reported to have several protein functions and to be localized to both the cytosol and nucleus.

    “PTGES3 protein is reported to have several protein functions and to be localized to both the cytosol and nucleus41–49 (Fig. 3f).”

    From Genome-scale CRISPR screens identify PTGES3 as a direct modulator of androgen receptor function in advanced prostate cancer (2025) · cites this paper as [48]

    The Introduction and Prostaglandin biosynthesis sections describe functions of AKR1C3, not PTGES3. Searches for PTGES3 and its alternative names found no passage in our copy addressing its functions or localization in the cytosol and nucleus. Page numbers were not available in the indexed passages. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
