Cell surface aminopeptidases play an important role in biological processes through degradation of small peptides. There are many bioactive peptides in ascites and these peptides are involved in carcinoma cell dissemination and infiltration. In human mesothelial cells dipeptidyl peptidase IV (DPPIV) shows the highest expression mostly in four cell surface aminopeptidases: aminopeptidase A, neutral endopeptidase 24-11, aminopeptidase N and DPPIV. Since mesothelial cells are always in contact with ascites, we examined the influence of malignant ascites on DPPIV. DPPIV enzyme activity in mesothelial cells was enhanced by the addition of ascites obtained from ovarian carcinoma patients in a time- and concentration-dependent manner, and flow cytometry and immunocytochemistry also revealed an increased expression of DPPIV on the cell surface of mesothelial cells. The <3-kD fraction of malignant ascites increased the DPPIV enzyme activity to the same level as the total ascites. Northern hybridization demonstrated that DPPIV mRNA was increased 3-fold by the addition of the <3-kD malignant ascites. In conclusion, DPPIV is highly expressed in human mesothelial cells and was regulated by ascites.
