Project description:The primary aim of the present study was to identify differences on the transcription level between ruptured and unruptured intracranial aneurysms as well as normal intracranial arteries in human. Keywords: Expression profiling by array Global gene expression profiling was performed in human intracranial aneurysms both ruptured (n=8) and unruptured (n=6) as well as in control intracranial arteries (middle meningeal artery, MMA; n=5) using oligonucleotide microarrays.

Project description:Background and Purpose—Analyzing genes involved in development and rupture of intracranial aneurysms can enhance knowledge about the pathogenesis of aneurysms, and identify new treatment strategies. We compared gene expression between ruptured and unruptured aneurysms and control intracranial arteries. Methods—We determined expression levels with RNA sequencing. Applying a multivariate negative binomial model, we identified genes that were differentially expressed between 44 aneurysms and 16 control arteries, and between 22 ruptured and 21 unruptured aneurysms. The differential expression of 8 relevant and highly significant genes was validated using digital polymerase chain reaction. Pathway analysis was used to identify enriched pathways. We also analyzed genes with an extreme pattern of differential expression: only expressed in 1 condition without any expression in the other. Results—We found 229 differentially expressed genes in aneurysms versus controls and 1489 in ruptured versus unruptured aneurysms. The differential expression of all 8 genes selected for digital polymerase chain reaction validation was confirmed. Extracellular matrix pathways were enriched in aneurysms versus controls, whereas pathways involved in immune response and the lysosome pathway were enriched in ruptured versus unruptured aneurysms. Immunoglobulin genes were expressed in aneurysms, but showed no expression in controls. Conclusions—For rupture of intracranial aneurysms, we identified the lysosome pathway as a new pathway and found further evidence for the role of the immune response. Our results also point toward a role for immunoglobulins in the pathogenesis of aneurysms. Immune-modifying drugs are, therefore, interesting candidate treatment strategies in the prevention of aneurysm development and rupture.

Project description:In the present study we aimed to investigate the systemic response to a rupture of intracranial aneurysms by an analysis of global gene expression profiles in peripheral blood cells. In addition, we sought to determine whether this approach could provide biomarkers related to clinical status of subarachnoid hemorrhage patients. Patients with subarachnoid hemorrhage from ruptured aneurysm were prospectively recruited from patients consecutively admitted to the Departments of Neurology or Neurosurgery and Neurotraumatology, University Hospital, Krakow, Poland in 2010 and 2011. Control subjects were recruited from patients of the Department of Neurology suffered from headaches.

Project description:Arraystar Human circRNA Microarray is designed for the profiling of human circRNAs. In this study, we applied a circRNA microarray to screen the potential biomarker for intracranial aneurysm. A total of 10 samples were used to perform microarray analysis. Our study contained 2 groups, un-ruptured intracranial aneurysm group(B1-B5) and ruptured intracranial aneurysm group(C1-C5). Each group contained five samples.
