Levels of mRNA for Nox2, Nox4, and tissue factor. mRNA levels for (A) Nox2, (B) Nox4, and (C) tissue factor in the aorta, measured by real-time PCR (n = 6-7 in each group). The values were normalized to GAPDH mRNA using the comparative threshold cycle (ΔΔC_T) method²⁵  and are expressed as percent of the control value seen in Cbs^+/+ mice fed the control diet. Values are mean ± SEM.
