Fig. 5From: Effects of mechanical strain on periodontal ligament fibroblasts in presence of Aggregatibacter actinomycetemcomitans lysateAgac lysate in combination with compressive strain increased the expression of inflammatory genes. Gene expression of tumor necrose factor (a TNF), interleukin-6 (b IL-6) and prostaglandin-endoperoxide synthase-2 (c PTGS-2) after treatment with Agac lysate and compressive strain; n ≥ 6; AU arbitrary units. Statistics: ordinary ANOVA with Holm-Sidak’s post hoc (TNF, PTGS-2) or Welch-corrected ANOVA with Games-Howell post-hoc tests (IL-6); *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001Back to article page
