Popis: | Many diseases are now associated with aberrant epigenetics and gene expression changes. Epigenetics can be modified by factors like diet. One dietary factor, folic acid, is consumed in various forms including supplements, energy drinks, and fortified grains. It was hypothesized high levels of folic acid would affect gene expression and enzyme activity of chromatin modifying enzymes as well as dendritic spine densities in a commonly utilized neuron model, the SHSY5Y cell. Decreased MBD2 and MECP2 were discovered upon treatment of SHSY5Y cells with a 2x folic acid dose. Corresponding decreases in dendritic spines were apparent in the 2x folic acid treated cells as well. Activity of DNMTs and H3K4 HMTs was altered. Further, H3K4me1, H3K4me3, H3K9Ac, and global DNA methylation were decreased in the 2x folic acid treated cells. Further studies are warranted to determine if the effects of excess folic acid are detrimental to organismal physiology. Highlights • The 2x folic acid treatment in SHSY5Y cells induces a significant decrease in MBD2 and MECP2 mRNA expression. • The excess folic acid also causes a significant increase in dendritic spines in SHSY5Y cells. • The 2x folic acid treatment increases DNMT activity and significantly decreases H3K4 HMT activity in SHSY5Y cells. • These findings align with some of those seen in autism spectrum disorders. |
