15-Deoxy-Δ12,14-prostaglandin J2 induces expression of 15-hydroxyprostaglandin dehydrogenase through Elk-1 activation in human breast cancer MDA-MB-231 cells.
We also demonstrate that cigarette smoke induces the expression of cyclooxygenase-2 and microsomal prostaglandin E synthase-1 and reduces 15-hydroxyprostaglandin dehydrogenase, resulting in prostaglandin E<sub>2</sub> release in human breast cancer.
15-Hydroxyprostaglandin dehydrogenase associates with poor prognosis in breast cancer, induces epithelial-mesenchymal transition, and promotes cell migration in cultured breast cancer cells.
