ABSTRACT = {It is known that the high electronegativity of fluorine affects various soft tissues, especially the bone structure in
organisms. Of these tissues are the kidneys, which play an important role in the excretion of fluoride from the body.
Fluoride affects many cellular mechanisms. One of these effects is DNA damage. Our study aimed to investigate the
likely protective effect of cholecalciferol (vitamin D3) on genomic DNA damage-induced NaF depending on
concentration and time. The IC25 and IC50 values of NaF for 3, 12 and 24 h and optimum dose of increase in
proliferation to vitamin D3 through MTT assay in NRK-52E kidney cells were determined. DNA damage was
significantly increased (p < 0.05) compared to the control group in all groups except for vitamin D3. It was
determined that treatment with NaF together with vitamin D3 decreased the DNA damage compared to NaF treated
groups for 3 and 12 h. NaF combined with vitamin D3 was determined statistically to decrease (p < 0.05) DNA
damage compared to NaF treated groups for 24 h. As a result, it was determined that the treatment with cytotoxic
concentration NaF depending on the time significantly increased (p < 0.05) the genomic DNA damage, but NaF
treatment together with vitamin D3 decreased the DNA damage in renal cells depending on the time. It was
concluded that vitamin D3 may be useful in preventing DNA damage caused by NaF.},
