Effect of some vitamins on antioxidant/prooxidant parameters in Sodium Fluoride (NaF)-treated Cell Line (hFOB 1.19)

Abstract

Objective: This study was planned to determine the effect of certain vitamin applications on antioxidant and oxidant parameters in the osteoblast cell line exposed to sodium fluoride in vitro and to evaluate the protective role of certain vitamins against possible toxic effects of fluoride.

Materials and Methods: Cells were replicated in vitro conditions with regular passaging 2-3 times weekly. MTF viability test was used to determine IC₅₀ of NaF (5000μM) and proliferative doses of vitamins (Vitamin A: 10μM, Vitamin D: 10μM, Vitamin E: 60μM, Vitamin C: 100μM) for hFOB 1.19 cells. Cells were sown in flasks as so to be 10⁶. The study groups were identified as control, NaF, vitamins and NaF+vitamins. After incubation for 24 hours, cells treated with trypsin were prepared by freeze/thaw method and MTT viability test, TAS, SOD, GSH, CAT, TOS and MDA analyzes were performed on these samples.

Results: In the hFOB 1.19 cell line, TAS levels decreased significantly in the NaF group (p≤0.05), but were close to the control group in NaF+vitamin groups with the exception of vitamin C. However, there was no difference between the groups in terms of GSH level and CAT and SOD activities when the control and NaF groups were compared. It was observed that TOS level increased significantly in the NaF group (p<0.05), decreased in the NaF+vitamin groups and were lower in the NaF+vitamin C and E groups than the control group (p <0.05). While OSI was the highest in the NaF group, no significant difference in MDA level was observed compared with the control group.

Conclusion: As a result, it was found that NaF administration in the osteoblast cell line increased oxidative stress and decreased following vitamin application. It was found that the effect of NaF administration in the osteoblast cell line on cell viability was consistent with the oxidative stability and that the vitamin application conformably changed cell viability and oxidative balance.
