Histone Acetylation In Periodontal Diseases, Sarang Saadat

Theses and Dissertations

Background: Emerging data has indicated the significant role of epigenetic control in inflammation. Acetylation of lysine residues on histones is a major epigenetic modification of chromatin, which is required for cytokine gene expression and regulated in inflammatory diseases. It has been shown that periodontal bacteria induce histone acetylation in oral epithelial cells and experimental periodontitis in rodents. In this study, we investigated the acetylation level of histone 3 (H3) in gingival tissue from healthy and periodontitis patients. We hypothesize that cytokine over-production in periodontitis is associated with the hyper acetylation of histones. Methods: Periodontitis and healthy subjects who need periodontal …
