Abstract

Multiple sclerosis (MS) patients should take medication such as fingolimod (FTY-720) for a long time, hence pharmaceutical effects on other neural cells such as dopaminergic cells are important. Dopaminergic cell line, BE(2)-M17, was treated by FTY-720 and then cell viability and genes involve in neurosurvival were investigated. It was disclosed that FTY-720 significantly stimulates Bcl2 overexpression. Whereas, it decreased intracellular reactive oxygen species production and cell membrane damage of dopaminergic cells. The increase in Bcl2/Bax ratio increased the cell metabolic activity and decreased propidium iodide-positive cells. Besides, FTY-720 induced the overexpression of CACNA1C, nNOS gene, and nitric oxide production. However, FTY-720 induced GABARA1 overexpression and eventually it could overcame to the cytotoxic effect of intracellular calcium. This cascade led to tyrosine hydroxylase and BDNF genes overexpression whereas FTY-720 did not change GDNF concentration in BE(2)-M17 cells. Concluding, it might be said that taking FTY-720 in MS patients did not induce adverse effect on dopaminergic cells. © 2019 Wiley Periodicals, Inc.
