OBJECTIVE To investigate the interactions of ovarian carcinoma cells and human peritoneal mesothelial cells (HPMC) involved in matrix metalloproteinases (MMP) expressions of ovarian carcinoma cells. METHODS The conditioned medium (CM) of ovarian carcinoma cell SKOV3 was tested by enzyme-linked immunosorbent assay (ELISA) for transforming growth factor beta1 (TGF-beta1). The impact of SKOV3-CM in the presence or absence of TGF-beta1 neutralizing antibody on fibronectin (Fn) gene expression of HPMC was studied by RT-PCR. HPMC were pretreated with serum-free medium, SKOV3-CM, SKOV3-CM + TGF-beta1 neutralizing antibody, and SKOV3-CM + IgG, then the supernatant was collected as HPMC-CM(1), HPMC-CM(2), HPMC-CM(3) and HPMC-CM(4). SKOV3 were incubated with different HPMC-CM, HPMC-CM(1) + antibody against Fn or HPMC-CM(1) + IgG. MMP-2 and MMP-9 gene mRNA expressions and protein expressions of SKOV3 were detected by RT-PCR and ELISA respectively. RESULTS TGF-beta1 in SKOV3-CM was (236 +/- 22) ng/L. Fn gene mRNA expressions of HPMC before and after stimulation by SKOV3-CM were 1.328 +/- 0.025 and 2.643 +/- 0.051, and the latter was higher than the former (P < 0.05). Fn gene mRNA expressions of HPMC stimulated by SKOV3-CM + TGF-beta1 neutralizing antibody was 1.897 +/- 0.035, which was less than that of SKOV3-CM group (P < 0.01). Before SKOV3 were incubated with HPMC-CM, MMP-9 protein and mRNA expressions were (14.5 +/- 1.6) microg/L and 1.50 +/- 0.04, but protein and mRNA expressions of MMP-2 were scarcely detected. When SKOV3 were incubated with HPMC-CM(1), mRNA expressions of MMP-2 and MMP-9 were 0.226 +/- 0.012 and 2.66 +/- 0.07, protein expressions were (15.0 +/- 0.8) and (37.2 +/- 3.5) microg/L, which were all higher than those of SKOV3 without treatment of HPMC-CM (P < 0.01). Following incubation of SKOV3 with HPMC-CM(1) + antibody against Fn, mRNA expressions of MMP-2 and MMP-9 were 0.138 +/- 0.007 and 1.82 +/- 0.06, protein expressions were (8.8 +/- 0.7) and (25.8 +/- 2.5) microg/L, which decreased compared with those of HPMC-CM(1) group (P < 0.01). Following incubation of SKOV3 with HPMC-CM(2), mRNA expressions of MMP-2 and MMP-9 were 0.467 +/- 0.018 and 4.28 +/- 0.09, protein expressions were (39.3 +/- 3.6) and (62.0 +/- 5.3) microg/L, which were higher than those of HPMC-CM(1) group (P < 0.01). Following incubation of SKOV3 with HPMC-CM(3), gene expressions of MMP-2 and MMP-9 were 0.331 +/- 0.015 and 3.52 +/- 0.08, protein expressions were (27.6 +/- 1.9) and (50.0 +/- 4.1) microg/L, which decreased compared with HPMC-CM(2) group (P < 0.05), but were still higher than those of HPMC-CM(1) group (P < 0.05). CONCLUSIONS Ovarian carcinoma cells activate HPMC through TGF-beta1, which induces higher expressions of MMP of ovarian carcinoma cells. Up-regulating Fn expression of HPMC may be one of action mechanisms of ovarian tumor cells. Fn derived from HPMC stimulates MMP-2 and MMP-9 expressions of ovarian carcinoma cells at gene and protein levels.

D010051	Ovarian Neoplasms	Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.

D010537	Peritoneum	A membrane of squamous EPITHELIAL CELLS, the mesothelial cells, covered by apical MICROVILLI that allow rapid absorption of fluid and particles in the PERITONEAL CAVITY. The peritoneum is divided into parietal and visceral components. The parietal peritoneum covers the inside of the ABDOMINAL WALL. The visceral peritoneum covers the intraperitoneal organs. The double-layered peritoneum forms the MESENTERY that suspends these organs from the abdominal wall.

D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D004847	Epithelial Cells	Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
