Abudalleh, A. M., T. Zhivkova, L. Dyakova, B. Andonova-Lilova and R. Alexandrova, 2013. Ammonium vanadate decreases viability and proliferation of cultured retrovirus-transformed chicken hepatoma cells. Bulg. J. Agric. Sci., Supplement 2, 19: 151–154
Vanadium compounds have been reported to possess anti-neoplastic potential especially against chemically induced liver, mammary, and colon carcinogenesis in rodents. According to the literature available, the anticancer activity of vanadium compounds in virus-transformed tumor cells has not been clarified yet. The aim of the study presented was to evaluate the effect of ammonium vanadate (NH4VO3) on viability and proliferation of cultured LSCC-SF-Mc29 cell line established from a transplantable chicken hepatoma, induced by the myelocytomatosis virus Mc29. The investigations were performed by thiazolyl blue tetrazolium bromide (MTT) test, neutral red uptake cytotoxicity assay (NR), colony-forming method (CFM) and double staining with acridine orange and propidium iodide (PI/AO). The results obtained revealed that applied at a concentration range of 0.1–20 µg/ml for 24–72 h NH4VO3 expresses significant cytotoxic and/or cytostatic effects that are time- and concentration dependent. Administered at concentrations ≥ 5 µg/ml this compound completely inhibit the colony-forming ability of chicken hepatoma cells.
