Diabetes mellitus (DM) is a common chronic disease that can cause various complications. Recently, there has been sharply increased in diabetes patients in Korea because of lifestyle change. When high-risk groups are diagnosed in early stage, immediate and suitable treatments can prevent the DM. However, accurate diagnosis in early stage of DM remains difficult due to its symptomless characteristic. Especially, Korean (Asian) have different risk factor for DM from European so that Korean specialized method is needed. We performed experiment using DM high-risk patient samples which were tracked past 10 years for discover DM early diagnosis biomarker specialized to Korean. Our research aims to identify the biomarkers that can predict whether high-risk patients would maintain their condition or develop to DM. Using Q-Exacitve mass Spectrometer, parallel reaction monitoring (PRM) was performed on the 80 patient digested serum samples to quantify 84 biomarker candidate proteins which are based on global profiling result. For sensitive and accurate quantification, 100 cm length long column and 200 min LC gradient were used in experiment. Stable isotope labeled peptides (, or AQUA peptides) were used to validate the targets identified in global profiling results and verify the expression changes of the targets.
