Fig. 1From: A flavonoid rich standardized extract of Glycyrrhiza glabra protects intestinal epithelial barrier function and regulates the tight-junction proteins expressionCytotoxic effect of FREG on Caco-2 cells. Caco-2 cells were treated with different concentrations of FREG for 48 h at 37 °C. Caco-2 cells viability was measured by MTT assay. Values are presented as mean ± standard deviation of the mean of three replicates. An asterisk indicates a significant (★p < 0.05) difference from cell controlBack to article page
