Abstract
Background and Objectives
Proteomics is a new technology that allows the detection and identification of several proteins at a given time in a sample. There are currently few reports concerned with the proteomic study of serum from patients during acute coronary syndrome. We performed proteomics to analyze the modifications in the serum protein map of patients with acute coronary syndrome (ACS).
Subjects and Methods
We investigated the serum from 12 patients who suffered with acute myocardial infarction (AMI), 12 patients with unstable angina (UA) and 13 age- and sex-matched patients as the control group. Two-dimensional electrophoresis, Coumassie staining and image analysis were performed. Mass spectrometry was performed to identify the selected spots.
Results
For the two-dimensional electrophoresis with using a pH range of 3 to 10, two different areas within the serum protein map were observed, and this showed differences between the groups. In area 1, three fibrinogen gamma chain isoforms were identified. All of them were increased in the serum from the AMI and UA patients when compared with the control group. In area 2, four fibrinogen beta chain isoforms were identified. Three isoforms of them were increased in the serum from the AMI and UA patients.
