Protein C activation and EPCR and thrombomodulin mRNA levels. Activation of protein C (A) and levels of EPCR mRNA (B) and thrombomodulin mRNA (C) in the aorta of Cbs^+/+ or Cbs^+/– mice fed either the control or HM/LF diets (n = 6-7 in each group). Levels of EPCR mRNA and thrombomodulin mRNA were normalized to levels of GAPDH mRNA. Values are mean ± SEM.
