Human Platelets PRM - A high glucose level is associated with decreased aspirin-mediated acetylation of platelet cyclooxygenase (COX)-1 at serine 529: A pilot study


ABSTRACT: The main aim of this study is to decipher the mutual impact that high glucose levels and diabetes have on aspirin-mediated acetylation of COX-1 through a targeted parallel reaction monitoring MS approach.

Diabetes is a major risk factor for cardiovascular diseases. Although aspirin is considered a cornerstone of the prevention and treatment of atherothrombotic-related ischemic events, this antiplatelet drug appears to be less effective in patients with poorly controlled diabetes. It has been suggested that the glycation of platelet proteins plays a pivotal role in poor responsiveness to aspirin. However, a direct effect on the critical residue (serine 529, or Ser 529) of the catalytic pocket of c  ...[more]
