The ensuing oxidative stress Selleck BGJ398 and inflammatory cascade result in the destruction of gingival tissue, alveolar bone and periodontal ligament. This article reviews the underlying mechanisms and host�Cbacteria interactions responsible for periodontal disease and evidence that nutritional supplementation with fish oil may provide a protective effect. Historical investigations of diet and disease have highlighted an inverse relationship between ingestion of fish oil, which is high in n-3 polyunsaturated fatty acids, and the incidence of typical inflammatory diseases such as arthritis and coronary heart disease. Ingestion of n-3 polyunsaturated fatty acids, such as docosahexaenoic acid and eicosapentaenoic acid, results in their incorporation into membrane phospholipids, which can alter eicosanoid production after stimulation during the immune response. These eicosanoids promote a reduction in chronic inflammation, which has led to the proposal that fish oil is a possible modulator of inflammation and may reduce the severity of periodontal diseases. Tentative animal and human studies have provided an indication of this effect. Further human investigation is needed to establish the protective effects of fish oil in relation to periodontal disease.

The effect of cyclic mechanical strain on the expression of adhesion-related genes by periodontal ligament cells in two-dimensional culture. J Periodont Res 2012; 47: 212�C221. ? 2011 John Wiley & Sons A/S Background and Objective:? Cell adhesion plays important roles Unoprostone in maintaining the structural integrity of connective tissues and sensing changes in the biomechanical environment of cells. The objective of the present investigation was to extend our understanding of the effect of cyclic mechanical strain on the expression of adhesion-related genes by human periodontal ligament cells. Material and Methods:? Cultured periodontal ligament cells were subjected to a cyclic in-plane tensile deformation of 12% for 5?s (0.2?Hz) Protease Inhibitor Library solubility dmso every 90?s for 6�C24?h in a Flexercell FX-4000 Strain Unit. The following parameters were measured: (i)?cell viability by the MTT assay; (ii)?caspase-3 and -7 activity; and (iii)?the expression of 84 genes encoding adhesion-related molecules using real-time RT-PCR microarrays. Results:? Mechanical stress reduced the metabolic activity of deformed cells at 6?h, and caspase-3 and -7 activity at 6 and 12?h. Seventy-three genes were detected at critical threshold values
