Authors' conclusion

This study provides a comprehensive site-resolved map of apo AI glycation in patients with diabetes and identifies the Apo AI Glycation Index as a glycation signature associated with diabetic CAS and impaired HDL function.

Study context

Population
Patients with type 2 diabetes with or without coronary atherosclerosis; diabetic mouse models
Participants
860 vs 294
Comparison
T2DM with coronary atherosclerosis (CAS) vs T2DM without CAS; glycation-resistant apo AICL vs glycated apo AI
  • CASn = 860
  • Controlsn = 294reference

Main finding

As reported in the abstract

Apo AI glycation sites and Apo AI Glycation Index in T2DM with vs without coronary atherosclerosis (CAS)
  • Apo AI glycation patterns differed between T2DM with and without CAS; K96 and K106/107 prominent disease-associated glycation sites
  • Apo AI Glycation Index independently associated with CAS and CAD in T2DM
  • Apo AI Glycation Index inversely associated with HDL-mediated reverse cholesterol transport and lecithin-cholesterol acyltransferase activity
