Abstract

Background: The objective was to evaluate the cytotoxic effect and mechanism of action of vitamins C (VC) and K₃ (VK₃) on ovarian carcinoma. Materials and Methods: Cytotoxicity assays were performed on ovarian cancer cell lines with VC, VK₃ or a VC/VK₃ combination. FIC index was employed to evaluate synergism. Flow cytometry was accomplished at 90% cytotoxic doses. Light, transmission electron microscopy and DNA isolation were performed. Results: Antitumor activity was exhibited by both VC, VK₃ and VC/VK₃ demonstrated synergistic activity. VC/VK₃ may induce a G₁, block in the cell cycle. Combined vitamin treatment resulted in cells that maintain apparently intact nuclei while extruding pieces of organelle-free cytoplasm. Degradation of chromosomal DNA was observed. Conclusion: Cell death (autoschizis) displayed characteristics of both apoptosis and necrosis. The cytotoxic effects observed may enable vitamins C and K₃ to play an adjuvant role in the treatment of ovarian cancer.
