Transcriptome-wide Analysis of Intracranial Artery of Moyamoya Disease Showing Up-regulation of Inflammatory Response with Increased Expression of TLR2 and SYK, and Down-Regulation of Collagen Formation with Decreased Expression of COL15A1 [STA]

ABSTRACT: During superficial temporal artery (STA)-middle cerebral artery (MCA) anastomoses, micro-samples of both MCA and STA from the patients with MMD (n=4) and internal carotid artery aneurysm (IA) (n=4) were collected. Using microarray technique, transcriptome-wide analyses were performed. Comparing MCA gene expression profile between MMD and IA, we detected 39 up-regulated and 12 down-regulated genes in MMD, showing over 15-fold change with significant difference (P<0.05). Gene set enrichment analysis revealed positive correlation of inflammatory response and negative correlation of collagen formation with MCA of MMD. In addition, by quantitative polymerase chain reaction, significant increased gene expression of TLR2 (P=0.009) and SYK (P=0.04), and decreased gene expression of COL15A1 (P=0.0001) in MCA of MMD were confirmed. While in STA transcriptome analysis, no gene showed significant difference.

Transcriptome-wide Analysis of Intracranial Artery in Patients with Moyamoya Disease Showing Up-regulation of Immune Response, and Down-regulation of Oxidative Phosphorylation and DNA Repair

Project description:Micro-samples of the middle cerebral artery (MCA) were collected from patients with MMD (n=11) and those with control (n=9). Using microarray techniques, transcriptome-wide analysis was performed. Comparison of the MCA gene expression between patients with MMD and control detected 62 and 26 genes whose expression was significantly (P<0.001, fold change>2) up- or down-regulated in the MCA of MMD. Gene set enrichment analysis of genes expressed in the MCA of MMD revealed positive correlations with genes involved in antigen processing and presentation, dendric cells pathway, cytokine pathway, and interleukin 12 pathway, whereas negative correlations with genes involved in oxidative phosphorylation and DNA repair. In addition, quantitative polymerase chain reaction analysis confirmed decreased gene expressions of tetraspanin 2 and ras homolog family member Q in MCA of MMD (P<0.05).

Long non-coding RNA profile of the intracranial artery in the patients with Moyamoya disease

Project description:We collected microsamples of the middle cerebral artery (MCA) from MMD patients (n = 21) and control patients (n = 11). Using microarray experiments, the profile of lncRNAs expression in MCA were compared between groups and differentially expressed lncRNAs (fold change > 2, q < 0.05) were identified. In addition, the neighboring coding gene whose transcription can be regulated in cis by the identified differentially expressed lncRNAs were investigated, and applied to Gene Ontology analysis for predicting those biological functions. We detected 308 differentially expressed lncRNAs (fold change > 2, q < 0.05), including 306 up-regulated and 2 down-regulated lncRNAs in the MCA from the MMD patients. As for the prediction of biological function, Gene Ontology analyses with possible coding genes whose transcription are regulated in cis by the identified differentially expressed lncRNAs suggested the involvement in antibacterial humoral response, T cell receptor signaling pathway, positive regulation of cytokine production, and branching involved in blood vessel morphogenesis. Quantitative polymerase chain reaction demonstrated a similar lncRNAs expression to the microarray experiments.

Role of STA-1 and SID-3 upon Orsay virus infection in C. elegans (RNA-Seq)

Project description:Across metazoans, innate immunity is vital in defending organisms against viral infection. In mammals, antiviral innate immunity is orchestrated by interferon signaling, activating the STAT transcription factors downstream of the JAK kinases to induce expression of antiviral effector genes. In the nematode C. elegans, which lacks the interferon system, the major antiviral response so far described is RNA interference but whether additional gene expression responses are employed is not known. Here we show that, despite the absence of both interferon and JAK, the C. elegans STAT homologue STA-1 orchestrates antiviral immunity. Intriguingly, mutants lacking STA-1 show increased resistance to antiviral infection. Using gene expression analysis and chromatin immunoprecipitation we show that, in contrast to the mammalian pathway, STA-1 acts as a transcriptional repressor. Thus STA-1 might act to suppress a constitutive antiviral response in the absence of infection. Using a reverse genetic screen we identify the SID-3 as a kinase upstream of STA-1 in the response to infection. Together, our work identifies a novel STAT regulatory cascade controlling its activity in antiviral resistance, illustrating the complex evolutionary trajectory displayed by innate immune signaling pathways across metazoan organisms.

MicroRNA and gene expression changes in human cerebral aneurysms [RNA-seq]

Project description:Cerebral Aneurysm tissues and superficial temporal arteries were compared through RNA-Seq to identify differentially expressed genes, and through microRNA microarray to identify differentially expressed microRNAs. Significant miR:gene pairs were identified for potential microRNA silencing regualtory effects. To study differentially expressed genes and microRNAs in cerebral aneurysms, we collected 7 cerebral aneurysm tisses and 10 superficial temporal artery (STA) tisses from 17 individuals. We performed RNA-Seq and microRNA microarray analysis on these samples, and compared them using STA as a control.

Clinical and Translational Study of STA-9090

Project description:The purpose of this study is to find out what effects, good and/or bad STA-9090 has on colorectal cancer. This is a phase II trial which tests both how well the drug works in fighting your cancer as well as any possible side effects it will have on the patient. Cancer is a disease of uncontrolled growth. This growth is controlled in part by a series of proteins that are part of a growth pathway. Some of these proteins are destroyed by a protein called HSP90 and STA-9090 is a test drug which blocks one of the proteins that helps cancer grow. This study will also look at molecular markers that may affect how the cancer grows, and how it responds to treatment.
