Effect of 6-gingerol on the expression of QS-inducible genes assessed by RT-qPCR.
The relative magnitude of gene expression level was defined as the copy number of cDNA of each gene in the biofilm cells normalized by the copy number of cDNA of the corresponding gene in biofilm cells without 6-gingerol. Error bars indicate the standard deviations of 3 measurements. **, P < 0.005 versus the control. *, P < 0.05 versus the control. The same volume of DMSO was added to the “0 μM 6-gingerol” treatments as the 6-gingerol treatments.
