title: Relationship between vitamin D binding protein and aspirin resistance in coronary ischemic patients: a proteomic study.
abstract: Our aim was to analyze the plasma proteome in aspirin (acetylsalicylic acid [ASA])-sensitive and ASA-resistant coronary ischemic patients. Plasma from 19 ASA-sensitive and 19 ASA-resistant patients was analyzed. For the proteomic study, two-dimensional electrophoresis was performed. The expression of one isotype of the fibrinogen gamma chain and three isotypes of haptoglobin was increased in ASA-resistant patients. Three vitamin D binding protein isotypes were increased in ASA-resistant patients. In vitro incubation of vitamin D binding protein (DBP) with blood from healthy volunteers reduced the inhibitory effect of ASA on thromboxane A2 production. DBP may be a new regulator of the inhibitory effect of ASA on platelets.
