in breast cancer tissue, cholesterol epoxide hydrolase ChEH metabolizes cholesterol-5,6-epoxide into cholestane-3beta,5alpha,6beta-triol, which is transformed into the oncometabolite 6-oxo-cholestan-3beta,5alpha-diol by 11beta-hydroxysteroid-dehydrogenase 11betaHSD2. ChEH inhibition and 11betaHSD2 silencing inhibit 6-oxo-cholestan-3beta,5alpha-diol production and tumor growth. Patient breast cancer samples show significantly increased 6-oxocholestan-3beta,5alpha-diol levels and greater ChEH and 11betaHSD2 protein expression compared with normal tissues, and 11betaHSD2 and ChEH overexpression correlate with a higher risk of patient death |
