ABSTRACT
BACKGROUND:
In the diseases process of the central nervous system, pathogenic factors stimulate microglia cells to over-activate and secrete inflammatory factors, which lead to further injury of neurons. Whether the deacetylase inhibitor sodium butyrate can reduce the over-activation and inflammatory effects of microglia cells caused by fluorosis is worthy of further study.OBJECTIVE:
To investigate the effects of sodium butyrate on fluorine-induced over-activation of microglia in the brain and the expression of inflammatory factors interleukin-1β, interleukin-6 and tumor necrosis factor-α.METHODS:
Microglia cells (BV-2) were routinely cultured in F12/DMEM medium containing 10% fetal bovine serum. CCK-8 method was used to observe the effects of sodium fluoride, sodium butyrate and their combination on the viability of BV-2 cells in logarithmic growth phase. The morphology of BV-2 cells after treatment with sodium fluoride, sodium butyrate and their combination, mRNA and protein expressions of interleukin-1β, interleukin-6 and tumor necrosis factor-α were observed by inverted microscope, RT-qPCR and western blot assay. RESULTS ANDCONCLUSION:
(1) CCK8 results showed that 25×10-6 sodium fluoride could reduce the viability of BV-2 cells, and 0.25 mmol/L sodium butyrate could increase the viability of BV-2 cells. Sodium butyrate 0.25 mmol/L could reverse the decreased viability of 25×10-6 sodium fluoride on BV-2 cells. (2) RT-qPCR and western blot assay results showed that 0.25 mmol/L sodium butyrate could antagonize the over-expression of interleukin-1β, interleukin-6 and tumor necrosis factor-α induced by 25×10-6 sodium fluoride. (3) It indicates that sodium butyrate, in a certain dose, can reduce the inflammatory response mediated by fluorium-induced microglia cells.
