Circular RNA expression profile in human primary multiple intracranial aneurysms

Project description:Primary multiple intracranial aneurysms (MIA) is a vascular disease that often leads to fatal vascular rupture and subarachnoid hemorrhage. However, little is known about the epigenetic regulation of MIA. Circular RNAs (circRNAs) serve important roles in cardiovascular diseases; however, they have received little research attention regarding their association with MIA. The present study initially aimed to explore novel mechanisms of MIA through circRNA expression profiles. Comprehensive circRNA expression profiles were detected by RNA sequencing (RNA-Seq) in human peripheral blood mononuclear cells. The RNA-Seq results were validated by reverse transcription-quantitative PCR. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses suggested the functions of these circRNAs. Among the 3,328 differentially expressed circRNAs between the MIA and matched groups, 60 exhibited marked expression changes (|log2 fold change|≥2; P<0.05). Among the 60 circRNAs that exhibited significant changes, 20 were upregulated, while the other 40 were downregulated. The circRNAs hsa_circ_0135895, hsa_circ_0000682 and hsa_circ_0000690 could regulate protein tyrosine kinase 2, protein kinase Cβ and integrin subunit αL, respectively. To the best of our knowledge, the present study was the first to perform circRNA sequencing analysis of MIA. Furthermore, the results specifically predicted the regulatory role of circRNAs in MIA pathogenesis.

Expression data from intracranial arteries and intracranial aneurysms

Project description:Gene expression information is useful in prioritizing candidate genes in linkage intervals. The data can also identify pathways involved in the pathophysiology of disease. We used microarrays to identify which genes are expressed in either intracranial arteries (control) or in intracranial aneurysms (case), and can therefore contribute to the disease phenotypes. We used microarrays to identify the pathway membership of expressed genes and the overrepresentation of pathways with expressed genes in the known linkage intervals for intracranial aneurysms. Keywords: Characterization of expression in both diseased and non-diseased intracranial arteries.

Global expression profiling of ruptured and unruptured human intracranial aneurysms

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.

Transcriptome-wide characterization of gene expression associated with unruptured intracranial aneurysms

Project description:The biological mechanisms by which cerebral aneurysms emerge, enlarge and rupture are not totally understood. In the present study, we analyzed the genome-wide gene expression profile in human intracranial aneurysms using cDNA microarrays. Intracranial arterial aneurysm samples (n = 3) and normal superficial temporal artery samples (control, n = 3) were obtained from individual subjects. All aneurysm samples were unruptured aneurysms confirmed by Magnetic Resonance Image or Digital Subtraction Angiography. Affymetrix HU133 Plus 2.0 microarrays were used to compare gene expression levels between aneurismal and normal blood vessels.

Gene expression profiling of blood in ruptured intracranial aneurysms

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.
