Title
(DE) BIOMARKER ZUR ÜBERWACHUNG VON INTERVENTIONSTHERAPIEN FÜR DIABETES

Abstract
(EN)
The use of N-linked glycosylation pattern of serum proteins as a biomarker for evaluating the efficacy of intervention therapies for diabetes is disclosed. As disclosed herein, changes in the N-linked glycosylation of total plasma proteins precedes and predicts the decrease in glycated hemoglobin (HbA1c) associated with successful treatment of diabetes. Therefore, measuring changes in N-linked glycosylation of total serum plasma proteins over time may be used as a biomarker to evaluate or access the efficacy of an intervention therapy for diabetes.

(FR)
Cette invention concerne l'utilisation du profil de N-glycosylation des protéines sériques à titre de biomarqueur pour évaluer l'efficacité des thérapies antidiabétiques interventionnistes. Comme décrit dans la présente, les variations de la N-glycosylation des protéines plasmatiques totales précèdent et prédisent la baisse de l'hémoglobine glyquée (HbA1c) associée au succès du traitement antidiabétique. Par conséquent, la mesure des variations de la N-glycosylation des protéines plasmatiques totales dans le temps peut être utilisée pour évaluer ou pour accéder à l'efficacité d'une thérapie antidiabétique interventionniste.
