Abstract
OBJECTIVE
To compare and optimize conditions for gene transfer to human endometrial stromal cells derived from primary culture and to determine the effect of interleukin-1beta (IL-1beta) and phorbol 12-myristate 13-acetate (PMA), a protein kinase C activator. on the promoter activity of the human cyclooxygenase-2 (COX-2) gene.
DESIGN
Prospective controlled study.
SETTING
Academic research laboratory.
PATIENT(S)
Women undergoing benign gynecologic surgery for indications other than endometrial diseases.
INTERVENTION(S)
Endometrial stromal cells were used for transient transfection study.
MAIN OUTCOME MEASURE(S)
Luciferase activity in transfected endometrial stromal cells.
RESULT(S)
Gene transfer mediated by cationic lipid was more efficient and more consistent. Lipofectamine, a polycationic lipid, yielded the highest efficiency. Phorbol 12-myristate 13-acetate (30 nM) and IL-1beta (100 ng/mL) increased COX-2 promoter activity by 2.6-fold and 2.2-fold, respectively.
CONCLUSION(S)
Induction of COX-2 by IL-1beta and PMA suggests that COX-2 and prostaglandin have important roles in the growth and differentiation of endometrial stromal cells. This model can be used to explore the roles of different promoter regulatory elements in COX-2 gene activation.
