Liver iNOS protein expression. a Representative immunoprecipitation blots of iNOS protein expressed in the liver of rats in the different groups. b Relative expression of iNOS protein by the different groups expressed densitometrically as a percentage of that of the normal control group using the bands in a. Expression was normalized to the expression of the corresponding internal control glyceraldehyde 3-phosphate dehydrogenase (GAPDH). Bars Mean ± SD, n = 8. Significant differences between groups are analyzed by one-way ANOVA, where: *P < 0.01 compared to normal control group, **P < 0.001 compared to normal control group, ^§ P < 0.001 compared to cancer control group
