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

Figure 1

Effects of live P. intermedia and A. naeslundii, and of Raspberry, 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 (0.2x), alone and in combination, for 4 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; R: Raspberry; Ch: Chicory; M: Mushroom; P.i./R: P. intermedia/R; P.i./Ch: P. intermedia/Ch; P.i./M: P. intermedia/M; A.n./R: A. naeslundii/R; A.n./Ch: A. naeslundii/Ch; A.n./M: A. naeslundii/M.
