Liver iNOS mRNA expression. a Representative reverse transcription (RT)-PCR photographs for the different groups. b Relative expression of iNOS mRNA of the different groups is expressed densitometrically as a percentage of that of the normal control group using the bands in a. Expression was normalized to that of the corresponding internal control β-actin mRNA. Bars Mean ± SD, n = 8. Significant differences between groups are analyzed by one-way ANOVA, where *P < 0.001 compared to the normal control group, § P < 0.001 compared to the cancer control group
