Revision as of 15:57, 22 May 2019
15-hydroxyprostaglandin dehydrogenase, also known as (15-PGDH) metabolises PG into the 15-Keto variant via the oxidation of 15(S)-hydroxyl group. The enzyme is constituently expressed in the skin (Finhelm1982) and within the eicosanoid network it is reported as metabolising PGE2 and PGF2a.
It should be noted that Judson et al found that 15-PGDH expression of the enzyme decreases in response to UVR (Judson2010).
