NIHMS793962-supplement-3.tif (1.1M) GUID:?D8C79EEA-8BAB-4909-B6EF-41410EF968B1 Abstract Epigenetic changes, such as alteration of DNA methylation patterns, have been proposed as a molecular mechanism underlying the effect of alcohol on the maintenance of adult stem cells. We have performed genome-wide gene expression microarray and DNA methylome analysis to identify molecular alterations via DNA methylation changes associated with exposure of human dental pulp stem cells (DPSCs) to ethanol (EtOH). By combined analysis of the gene expression and DNA methylation, we have found a significant number of genes that are potentially regulated by EtOH-induced DNA methylation. As a focused approach, we have also performed a pathway-focused RT-PCR array analysis to examine potential molecular effects of EtOH on genes involved in epigenetic chromatin modification enzymes, fibroblastic markers, and stress and toxicity pathways in DPSCs. We have identified and verified that lysine specific demethylase 6B (with alterations in the expression of differentiation markers. Knockdown of resulted in a marked decrease in mineralization from implanted DPSCs in EtOH-treated DPSCs restored the expression of differentiation-related genes. Our study has demonstrated that EtOH-induced inhibition of plays a role in the dysregulation of odontogenic/osteogenic differentiation in the DPSC model. This suggests a potential molecular mechanism for cellular insults of heavy alcohol consumption that can lead to decreased mineral deposition potentially associated with abnormalities in dental development and also osteopenia/osteoporosis, hallmark features of fetal alcohol spectrum disorders. [14] while another identified that DPSCs undergo osteogenic differentiation through the NF-kB signaling pathway [15]. DPSCs had the ability to differentiate toward both odontogenic and osteogenic lineages in presence of a carboxymethyl cellulose-hydroxyapatite hybrid hydrogel [16]. Furthermore, medium modification with bone morphogenetic protein 2 was shown to stimulate odontogenic differentiation and formation of an osteo-dentin matrix [17]. Although DPSCs have been long studied for their regenerative capabilities in both dentistry and orthopedics, the molecular mechanisms controlling their stem cell potency have yet to be discovered. It has been shown that in controlling expression through the removal of H3K27me3 in human BMSCs [18]. A recent study has shown to play a critical role in the epigenetic regulation of odontogenic differentiation in human DPSCs [19]. In DPSCs, knockdown studies resulted in decreased alkaline phosphatase activity and alizarin red staining, and reduced expression levels of marker genes, including osterix (value minimum cutoff (?log10) of 2. Using a custom Unix code, we aligned ratio peak (and values ( 0.05) for each EtOH concentration treatment (20 mM or 50 mM) for further selection and validation (Table 1).
