title: Effects of resveratrol on expression of vascular endothelial growth factor in human gingival fibroblasts stimulated by periodontal pathogens.
abstract: OBJECTIVE
  To investigate the effects of resveratrol, a naturally occurring polyphenol, on the expression of vascular endothelial growth factor (VEGF) in human gingival fibroblast culture in response to vesicles and outer membrane proteins from periodontopathic bacteria.
  
  
  METHODS
  Human gingival fibroblasts were stimulated with vesicles and outer membrane proteins from Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis. In human gingival fibroblast cultures treated with or without resveratrol, VEGF production was evaluated by means of enzyme-linked immunosorbent assay and VEGF mRNA expression by means of reverse transcription polymerase chain reaction analysis. Vascular permeability enhancement was measured by the leakage of intravenously injected dye at the injection site of supernatant from cultures of human gingival fibroblasts stimulated by vesicles and outer membrane proteins.
  
  
  RESULTS
  Resveratrol significantly inhibited the increased production of VEGF by human gingival fibroblasts in response to vesicles and outer membrane proteins from periodontopathic bacteria, as shown by the detection of these proteins and their mRNA in vitro. Moreover, resveratrol treatment significantly decreased vascular permeability enhancement induced by supernatant from human gingival fibroblast cultures stimulated by vesicles and outer membrane proteins.
  
  
  CONCLUSIONS
  Overall, these findings suggest that resveratrol inhibits production of VEGF by stimulated human gingival fibroblasts and can inhibit vascular permeability, suggesting a therapeutic role for it in pathogenic bacteria-induced periodontal inflammation.
