Abstract：
BACKGROUND:Vitamin D is known for its anti-cancerogenous potential. Prostaglandin E2 (PGE2) is a proliferation and inflammation activating agent. The production of PGE2 is dependent on the activity of cyclooxygenase-2 (COX-2). A link between vitamin D and PGE2 metabolism was recently shown. MATERIALS AND METHODS:In MDA-MB-231 and MCF-7 breast cancer cell lines we investigated the influence of calcitriol and the COX-2 inhibitor celecoxib regarding cell growth via MTT test, as well as on the protein and mRNA expression of COX-2 using western blot and qRT-PCR. RESULTS:The proliferation of MCF-7 and MDA-MB-231 was inhibited by both calcitriol and the COX-2 inhibitor celecoxib and even stronger by their combination. Moreover, calcitriol inhibited the COX-2 protein expression in MDA-MB-231, as well as the COX-2 mRNA expression in both cell lines. CONCLUSION:The combination of calcitriol and celecoxib demonstrated a cooperative growth-inhibiting effect in breast cancer cell lines.

杂志文章abstract：BACKGROUND:The pS2 protein is involved in the maintenance of the integrity of the gastrointestinal tract. In breast cancer pS2 can be demonstrated in at least half of the tumors and probably reflects the functional status of ER. Several features make it likely that pS2 is involved in growth regulation.
