Expression profiles of iron transporter mRNAs in isolated human monocytes. Isolated blood monocytes were subjected to RNA preparation, followed by reverse transcription and quantitative TaqMan PCR. Specific values of target genes were normalized to those of 18sRNA. Data are shown as means ± SD for relative abundances. **P < .005 or *P < .05 when comparing control with iron-deficiency anemia (IDA) or anemia of chronic disease (ACD) patients, respectively, by means of Student t test. Data are shown as means (horizontal lines) ± SD (error bars) for relative abundance.
