Effects of Individual Nutraceuticals on LLC-PK1 Tight Junctional Proteins.

Summary of effects of various nutraceuticals on a panel of eight tight junctional proteins in LLC-PK1 cell layers. Studies were performed as described for quercetin in Figure 3. Data shown represents the mean ± standard error for an n = 3 cell layers in all cases. P values are listed for instances of statistical significance (Student's t [one tailed] to at least the PTable 1, the concentration providing the maximal enhancement of barrier function. Boldface signifies greater than 30% increase; italics signifies greater than 30% decrease induced by that nutraceutical in order to emphasize the various patterns specific to each nutraceutical.
