Abstract |
15-Hydroxprostaglandin dehydrogenase (15-PGDH) mediates a colon neoplasia suppressor pathway, acting through metabolic antagonism of cyclooxygenase-mediated colon carcinogenesis. To determine whether the colon tumor prevention activity of 15-PGDH acts as a constant or variable effect among individuals, we determined whether 15-PGDH levels remain stable over subsite and time in the human colon, determined the extent of differences in 15-PGDH levels between different individuals, and determined whether 15-PGDH modulation mediates any part of the anti-colon tumor effect of aspirin. |
