AB Background/Aim: To investigate the role of the expression of hypoxia-related genes on the prognosis of ovarian clear cell carcinoma (OCCC). Materials and Methods: Basal mRNA levels of eight hypoxia-related genes were compared. Cell viability was assayed after treating ES-2 cells under hypoxic conditions. The mRNA and protein levels were evaluated after the induction of hypoxia and administration of increased doses of N-acetylcysteine (NAC). Finally, the prognostic role of their expression levels was evaluated in 61 patients with OCCC. Results: The mRNA and protein levels of maspin increased gradually with the induction of hypoxia. Maspin protein expression decreased after treatment with paclitaxel and NAC. High expression of maspin was related to poor progression-free and overall survival in patients with OCCC (adjusted hazard ratios, 3.97 and 7.47; 95% confidence intervals=1.34-11.81, and 1.98-28.13). Conclusion: High expression of maspin induced by hypoxia might be associated with poor prognosis of OCCC.
