Project description:High throughput miRNA microarray screening approach, we compared the miRNA expression pattern in ruptured aneurysm tissues obtained during surgery from patients with aneurysmal subarachnoid hemorrhage (aSAH) with control tissues. Aim was to determine miRNA signature in aneurysmal tissues.
Project description:To identify miRNAs which could be involved in TAA (Thoracic Aortic Aneurysm) pathogenesis, we first performed miRNAs microarrays using the aortic media of healthy controls and TAA patients. 473 miRNAs were detected in at least half samples. Among them, 232 miRNAs were differentially expressed with adjusted p value < 0.05 and log2 transformed fold change > 0.5 or < -0.5.

Project description:Sox2 has been studied in several types of human solid tumors. The investigators found that Sox2 had higher expression level in colorectal cancer and metastatic tissues than normal tissues. So the investigators assumed that whether Sox2 plays an important role in the progression and migration of colon cancer.
Project description:Single-molecule level spatial distribution of MERFISH (Multiplexed error-robust fluorescence in situ hybridization) probes targeting 140 genes were analyzed on two control (non-aneurysmal) samples and three TAA samples with Thoracic aortic aneurysm (TAA).
Project description:Cerebellar vasospasm is a severe complication of aneurysmal subarachnoid hemorrhage (aSAH) occurring for 30% of aSAH patients. To date, no biomarker of vasospasm occurrence exists and thus all aSAH patients undergo a preventive and dangerous treatment. In this study, we explored the miRNome of aSAH patients to detect potential expression differences between the patients developing a vasospasm (VSP+) or not (VSP-). The shared data include raw and normalized count miRNA data in aneurysmal subarachnoid hemorrhage patients with or without vasospasm.
Project description:To understand the mechanism of coronary artery aneurysmal dilatation, we identified and compared the expression of circulating miRNAs in three groups of patients. Group 1 enrolled patients with aneurysmal dilatation of coronary arteries (n = 20), Group 2 included patients with angiographically confirmed coronary artery disease (CAD), whereas Group 3 included 20 patients with normal coronary arteries. The miRNAs were isolated from plasma and profiled using PCR arrays miRCURY LNA Serum/Plasma Focus PCR Panels. We demonstrated that the plasma miRNAs levels were significantly different in Group 1 in collation with Group 2 and Group 3 (fold change > 2 and p < 0.05). The comparison of Group 1 with Group 3 identified twenty-one significantly up-regulated and two down-regulated miRNAs in patients with aneurysmal coronary artery dilatation compared to the control groups. Moreover, we identified six up-regulated and two down-regulated miRNAs in patients with CAD compared to the controls. The third comparison revealed four up-regulated and three down-regulated miRNAs in Group 1, when compared to CAD patients. In conclusion, this study demonstrates the specific signature of plasma miRNA, namely up-regulated and down-regulated, in patients with abnormal dilatation of coronary arteries and the comparison between the groups consisting of atherosclerotic and control patients.
