Figure 1s. Change in SOD gene expression in hepatocytes exposed to treated and untreated wastewaters.

Gene expression was measured by qPCR. The filled and dotted lines represent the mean ± 1 standard deviation of the ethanol solvent control. Asterisks (*) indicate a significant (p<0.05) difference between the observed responses in the influent and effluent.

Figure 2s. Change in CYP1A1 gene expression in hepatocytes exposed to treated and untreated wastewaters.

Gene expression was measured by qPCR. The filled and dotted lines represent the mean ± 1 standard deviation of the ethanol solvent control. Asterisks (*) indicate a significant (p<0.05) difference between the observed responses in the influent and effluent.

Figure 3s. Change in CYP3A4 gene expression in hepatocytes exposed to treated and untreated wastewaters.

Gene expression was measured by qPCR. The filled and dotted lines represent the mean ± 1 standard deviation of the ethanol solvent control. Asterisks (*) indicate a significant (p<0.05) difference between the observed responses in the influent and effluent.

Figure 4s. Change in GST gene expression in hepatocytes exposed to treated and untreated wastewaters.

Gene expression was measured by qPCR. The filled and dotted lines represent the mean ± 1 standard deviation of the ethanol solvent control. Asterisks (*) indicate a significant (p<0.05) difference between the observed responses in the influent and effluent.

Figure 5s. Change in MDR gene expression in hepatocytes exposed to treated and un treated wastewaters.

Gene expression was measured by qPCR. The filled and dotted lines represent the mean ± 1 standard deviation of the ethanol solvent control. Asterisks (*) indicate a significant (p<0.05) difference between the observed responses in the influent and effluent.

Figure 6s. Change in VTG gene expression in hepatocytes exposed to treated and untreated wastewaters.

Gene expression was measured by qPCR. Asterisks (*) indicate a significant (p<0.05) difference between the observed responses in the influent and effluent.

Figure 7s. Change in ER gene expression in hepatocytes exposed to treated and untreated wastewaters.

Gene expression was measured by qPCR. The filled and dotted lines represent the mean ± 1 standard deviation of the ethanol solvent control. Asterisks (*) indicate a significant (p<0.05) difference between the observed responses in the influent and effluent.
