Relative expression of genes involved in hrp regulation with FA treatment. Cells were grown in hrp-inducing medium to an OD₆₀₀ of approximately 0.1 and subjected for β-galactosidase assay. Normalized value with FA treatment was divided with that of control and relative values were presented. Each test was repeated in at least three independent trails and each trails included two replications. Mean values were averaged and presented with SD (error bars). Statistical significance between FA treatment and the DMSO control was assessed using a post hoc Dunnett test following ANOVA. Significance level, ^∗p < 0.05 and ^∗∗p < 0.01.
