T1 112-386 OBJECTIVE denotes To screen differentially expressed proteins of saccular intracranial aneurysms and superficial temporal artery by the proteomics analysis using isobaric tags for relative and absolute quantification (iTRAQ) combined with reverse phase high-performance liquid chromatography.
T2 396-796 METHODS denotes Collecting 17 samples from intracranial aneurysm patients undergoing aneurysmectomy as experiment group and 17 matched STA as control group. After quantification and enzymolysis of the protein, the iTRAQ were used to label the peptides of the 2 groups respectively. Then, the mixture of the peptides was fractioned by RP-HPLC and analyzed by LC-MS/MS to identify the differential expression proteins.
T3 806-1911 RESULTS denotes A total of 1699 proteins were identified from the ProteinPilot 4.5 software (AB SCIEX) using the Paragon database search algorithm. Comparing with STA, 54 proteins were significantly up-regulated (115:114<0.5-fold) and 37 were significantly down-regulated in sIAs (115:114>2.0-fold). Furthermore, Integrin β3, Secreted frizzled-related protein 2 were significantly up-regulated (2.3 fold and 2.1 fold, respectively), whereas MyosinIIb, Alpha-actinin-1, Laminin β2, and Carboxypeptidase A3 were down-regulated (3.01 fold, 2.1 fold, 2.07 fold, and 2.01 fold, respectively) in sIAs. GO Ontology analysis showed that most differential proteins expressed in cytoskeletal; up-regulated proteins in sIAs play an important role in inflammatory reaction, enzymatic hydrolysis, cell adhesion and invasion, and cellular immune reaction; down-regulated proteins in sIAs involved in cytoskeletal protein, enzyme, and structural protein. ITGB3, ACTN1 and MYL2 play a role in aneurysm formation via focal adhesion pathway. The results of Western-blot assay were consistent with the proteomic changes of those 6 proteins.
T4 1924-2190 CONCLUSIONS denotes The differentially expressed proteins in sIAs that showed aneurysm formation are related to cytoskeleton abnormal and extracellular matrix changes. The iTRAQ technology provides scientific foundation for the further study to explore the pathogenic mechanism of sIAs.
