General Information | Comment | Organism |

malfunction | although attenuating AKR1C3 expression in squamous cell carcinoma cells by siRNA does not affect growth, treatment with PGD2 and its dehydration metabolite, 15delta-PGJ2, decreases squamous cell carcinoma, SCC, proliferation in a PPARgamma-dependent manner. In addition, treatment with the PPARgamma agonist pioglitazone profoundly inhibits squamous cell carcinoma proliferation. SCC-AKR1C3 metabolizes protaglandin D2, PGD2, to 9alpha,11beta-prostaglandin F2 12fold faster than the parent cell line and is protected from the antiproliferative effect mediated by PGD2. PGD2 and its metabolite 15delta-prostaglandin J2 attenuate SCC proliferation in a PPARgamma-dependent manner, therefore activation of PPARgamma by agonists such as pioglitazone may benefit those at high risk of SCC | Homo sapiens |
physiological function | AKR1C3 is overexpressed in skin squamous cell carcinoma (SCC) and affects SCC growth via prostaglandin metabolism. AKR1C3 is overexpressed in various malignancies, suggesting a tumor promoting function. SCC-AKR1C3 metabolizes protaglandin D2, PGD2, to 9alpha,11beta prostaglandin F2. Unlike other AKR1C members, AKR1C3 can synthesize prostaglandin F2alpha from prostaglandin H2, an arachidonic acid derivative synthesized by cyclooxygenase | Homo sapiens |
