Effects of Fruit and Vegetable Low Molecular Mass Fractions on Gene Expression in Gingival Cells Challenged with Prevotella intermedia and Actinomyces naeslundii

Figure 3

Effects of heat killed P. intermedia and A. naeslundii, and of Chicory and Mushroom LMM fractions on KB cell viability. Cells were exposed to bacteria (at the nominal bacteria: KB cell ratio of 50) and fractions (0.1x), alone and in combination, for 6 h. Cell viability was evaluated by the MTT assay as described in Methods. Data, expressed as percent cell viability with respect to controls, represent the mean ± SD of four experiments in triplicate. P.i.: P. intermedia; A.n.: A. naeslundii; Ch: Chicory; M: Mushroom; P.i./Ch: P. intermedia/Ch; P.i./M: P. intermedia/M; A.n./Ch: A. naeslundii/Ch; A.n./M: A. naeslundii/M.
