To study the effects of OPG on alveolar bone protection, an experimental periodontitis model was used by placing a bacterial plaque retentive silk ligature in the gingival sulcus around the maxillary second molar tooth, injection of Porphyromonas gingivalis and high carbohydrate diet. A total of 30 Sprague�CDawley rats were randomly divided into three groups, with 10 rats in each group: group I (control) was treated with 10?��L normal saline injection; group II with 10?��L mock vector; and group III with 10?��L local OPG gene transfer by transfection with in vitro constructed pcDNA3.1-human OPG (pcDNA3.1-hOPG). A subperiosteal injection was done adjacent to the second molars on days 0, 7, [http://en.wikipedia.org/wiki/Unoprostone Unoprostone] 14 and 21. Four weeks later, all animals were killed and radiographic, histological and immunohistochemical examinations were performed. Statistical analysis included ANOVA and LSD-Bonferroni test. Group III (OPG gene therapy) had significantly enhanced (p?[http://www.selleckchem.com/products/bgj398-nvp-bgj398.html see more] and active osteoclast number (p?[http://www.selleckchem.com/screening/protease-inhibitor-library.html Protease Inhibitor Library concentration] were cultured in the presence of Na2S/HCl or in the presence of H2S produced enzymatically by the action of Treponema denticola cystalysin (l-cysteine desulfhydrase) on l-cysteine. Apoptosis was assessed morphologically after nuclear staining with DAPI or was quantified by flow cytometry after staining with annexin V. Caspase activation was measured by an enzymatic assay using DEVD-AMC, a synthetic caspase substrate. Results:? Among the three products obtained following degradation of l-cysteine by T.?denticola cystalysin, only H2S induced significant apoptosis in HGF cells. Hydrogen sulfide also induced typical apoptotic morphology in cultured PDL cells.
