Transcription level of the genes for TMA metabolic enzymes. (a) Chemical reaction of TMA dehydrogenase. This enzyme catalyzes the oxidative demethylation of TMA to form formaldehyde and dimethylamine. (b) The transcript levels of TMA dehydrogenase were detected in the total mRNA of the foot tissue by qRT-PCR analysis using the specific primers. Three to five mice per group were used to prepare the total RNAs, and qRT-PCR was assayed in duplicate for each sample. The data are reported as the means ± SD. compared with the vehicle-treated group. FMO3, flavin-containing dimethylaniline monooxygenase 3; TMA, trimethylamine; EESJ, 70% ethanol extract of S. japonica; mRNA, messenger ribonucleic acid; qRT-PCR, quantitative real-time polymerase chain reaction.
