摘要

Lipocalin-type prostaglandin D synthase (LPGDS; PGH(2)D-isomerase; EC 5.3.99.2) is a bifunctional protein first identified in the mammalian brain. It acts as a PGD(2)-producing enzyme and a retinoid transporter. Recent studies have shown that LPGDS is anomalously expressed in ovarian tumors and that retinoid may have a role as an ovarian cancer chemotherapeutic agent. To determine whether there is a relationship between retinoid and LPGDS in ovarian tumors, we examined the regulation of the gene encoding LPGDS by all-trans retinoic acid (RA). Real-time quantitative RT-PCR analysis showed that RA strongly induced the accumulation of LPGDS mRNA in human 3AO ovarian cancer cells. Furthermore, treatment of the cells with RA induced the synthesis and secretion of LPGDS into the culture medium. This increased expression of LPGDS was accompanied by an inhibition of cell proliferation in the ovarian cancer cells.
