ABSTRACT
<p><b>OBJECTIVE</b>To study the relationship between the expression of dipeptidyl peptidase IV (DPP IV) gene and malignant behavior of cells of ovarian carcinoma.</p><p><b>METHODS</b>The differences of the malignant behavior of A2780, SKOV-3, HO-8910 and HO-8910PM cell lines were examined by drawing cell proliferative curves, adhesive test, assay of incursion and chemotaxis. The expression of DPP IV among the cell lines and its relationship with the malignant behavior of ovarian carcinoma cell were detected by techniques of DPP IV activity assay, cytometry and reverse transcription polymerase chain reaction.</p><p><b>RESULTS</b>Among all cell lines, the ability of proliferation, adhesion, incursion and chemotaxis of HO-8910PM were the highest, while those of A2780 were the lowest. The transcription of mRNA in A2780, SKOV-3, HO-8910 and HO-8910PM cell lines were 0.7512 +/- 0.0012, 0.5596 +/- 0.0015, 0.3369 +/- 0.0009, and 0.2777 +/- 0.0006, respectively. The activity of DPP IV were 0.79 +/- 0.02, 0.64 +/- 0.03, 0.21 +/- 0.02, and 0.18 +/- 0.01, respectively; and the protein expression of DPP IV gene were 657.83 +/- 1.14, 538.53 +/- 5.29, 130.50 +/- 1.46, and 33.14 +/- 0.47, respectively, as assayed by cytometry. The correlation coefficients of the transcription of DPP IV gene and the adhesive, incursive and migratory ability of ovarian carcinoma cells were -0.987, -0.983, and -0.991, respectively; the correlation coefficients of the expression of DPP IV and those ability of cells were -0.959, -0.988, and -0.968; the correlation coefficients of the activity of DPP IV and those ability of cells were -0.952, -0.868, and -0.983.</p><p><b>CONCLUSION</b>There is a negative correlation between the expression of DPP IV gene and the adhesive and incursive capability of cells of ovarian carcinoma.</p>
