Epithelial ovarian cancer (EOC) is the most common and lethal of the ovarian neoplasms, frequently it is detected at advanced stages of the disease resulting in 60–70% of the cases in recurrence and less responsive to chemotherapy. Currently the role played by the neurohypophyseal hormone arginine vasopressin (AVP) and its receptors in the development of EOC is unknown. The purpose of this study was to evaluate the action of desmopressin (DDAVP), an AVP V2 receptor agonist on the cell proliferation and cell migration in cells from the OV‐90 cell line. Cell proliferation was evaluated with the proliferation marker Ki67, whereas the cells migration was evaluated by the wound assay. The AVP V1a and V2 receptors expression were assessed by immunofluorescence. Cell cultures were stimulated during 12, 24, 36 and 48 hours with DDAVP (500 to 1500 mM). In order to discard the cytotoxicity of DDAVP on the OV‐90 cell cultures in control and stimulated cultures the Cytotox 96 kit was used. The experiments were performed three times by duplicate. The results showed that the expression of AVP V1a and V2 receptors are present in both DDAVP stimulated and‐non stimulated cultures. On the other hand in comparison with the control cultures, doses of 1000mM of DDAVP significantly (p<0.05) inhibit both cell proliferation and cellular migration. Present results also suggests a possible inhibitory role of DDAVP on proliferation and cellular migration in the OV‐90 cell lines of epithelial ovarian cancer.Support or Funding InformationUniversidad Autónoma de Aguascalientes PIFF14‐1 and CONACYT 221262.
