This study was planned to evaluate the
effect of vitamin D administration on cytotoxicity due to fluoride exposure in vitro.
NaF (IC50) and vitamin D
(proliferative) were applied to human osteoblast (hFOB 1.19) cells. The major
genes of apoptotic, autophagic, and necrotic pathways were determined by
RT-PCR. 2-∆∆Ct formulation was used for expression analysis.
In the NaF group, Caspase 3, Bax, Bad,
Bak, Bclx, Atg3, Atg5, Atg6, pG2, LC3-I, LC3-II, RIP1, RIP3 genes were
increased (2.6-15 times). It was observed that the expressions of these genes
approached the control when Vitamin D was given together with NaF. The Bcl2 gene increased significantly (6-fold) with the effect of
NaF, and was down-regulated to some extent with additional vitamin D
administration, but still more than in the control.
As a
result, it was determined that apoptotic, necrotic and autophagic pathways were
activated as the molecular basis of the damage in the bone tissue, which was
most affected by fluorine, and these genes were down-regulated and approached
the control group with the addition of vitamin D. It was concluded that this is
an important data to explain the molecular basis of the protective and
therapeutic effect of vitamin D against fluorine toxicity.
