Effect of fucoxanthin rich powder on mRNA expression of transcription factor and enzymes related to antioxidant system in the liver of rats. Total RNA was isolated using TRI-reagenet, and cDNA was synthesized using 3 ug of total RNA with SuperScript II reverse transcriptase. Realtime PCR was performed using SYBR green and standard procedures to assess the mRNA expression of the primer in liver samples obtained from each group. An Applied Biosystem StepOne softwere v2.1 was used. Each bar represents the mean ± S.E of three independent experiments. Different letters above each bar indicate significant differences among the groups at α = 0.05 as determined by Duncan's multiple range tests. HO-1: heme oxygenase (decycling) 1, Nrf2: nuclear factor, erythroid derived 2, like 2, NQO-1: NAD(P)H quinone oxidoreductase 1.
