Abstract:
Objective To screen serum differential proteins for childhood asthma at different control levels,which provided the basis for the prevention and treatment of childhood asthma. Methods Isobaric tags for relative and absolute quantification,two-dimensional liquid chromatography,nanoelectrospray ionization,and high-resolution tandem mass spectrometry using the hybrid quadrupole time-of-flight platform was used to screen the differential proteins in serum samples from pediatric patients with controlled,partly controlled,or uncontrolled childhood asthma. Differential proteins were validated using enzyme-linked immunosorbent assay (ELISA). Results A total of 260 expressed proteins were identified. Among them 57 differentially expressed proteins were found among the different control levels of childhood asthma (fold<0.8 or fold>1.2). The differentially expressed proteins were involved mainly in 21 biological processes and 8 molecular functions and were located in 17 cellular components. ELISA showed that the serum vitronectin level was significantly higher in controlled group [(573.92±412.43) μg/ml] than in uncontrolled group[(382.27±238.64)]μg/ml (P=0.0399). Conclusion We identified 57 differential proteins for childhood asthma at different control levels,which may be used as potential biological targets for the control of childhood asthma.
