Gene expression data from aortic tissues of PPE-AAA mice receiving systemic lenvatinib treatment

Project description:Abdominal aortic aneurysm (AAA) is a disease with high morbidity and mortality, especially when ruptured. The rationale of this study was to evaluate the repurposing of lenvatinib, a multi–tyrosine kinase inhibitor, in limiting experimental AAA growth targeting vascular smooth muscle cells (VSMCs) and angiogenesis. We applied systemic lenvatinib treatment to porcine pancreatic elastase(PPE)-induced murine aortic aneurysms and profiled their gene expression through Affymetrix MTA1-0 microarray.

MicroRNA transciptional profiling in murine abdominal aortic aneurysm (AAA), porcine pancreatic elastase (PPE) model - Day 7

Project description:We sought to identify differentially regulated microRNAs in infrarenal mouse aortic tissue after AAA-induction with PPE, compared with sham-operated mice. This treatment leads to rapid development of infrarenal aortic aneurysms with significant diameter differences observed by Day 7. We found 41 miRNAs were up-regulated with aneurysm and 37 down-regulated at p<0.05, which were also altered by >1.5-fold. Utilizing the PPE infusion model, we induced AAA in Male 10-week-old C57/Bl6 mice, 7 days after AAA-induction with PPE. One array per mouse, 5 mice per group, two groups (PPE and sham).

Murine Abdominal Aortic Aneurysm, PPE Model: Transcriptional Profiling of Sham vs. AAA at Day 7

Project description:Transcriptional profiling of infrarenal aortic tissue from Male 10-week-old C57BL/6J mice after AAA-induction with porcine pancreatic elastase, compared with sham-operated mice. Includes samples obtained 7 days after aneurysm induction. Goal was to examine gene expression in developing AAA in this model, and compare with miRNA profiling performed using the same tissue. Two condition experiment, one infrarenal aorta per array. Sham vs. PPE at Day 7 post-operatively. Total 10 arrays: 5 sham D7, 5 PPE D7.

Murine Abdominal Aortic Aneurysm, PPE Model - In Vivo Modulation of miRNA-24 (Day 7)

Project description:Transcriptional profiling of infrarenal aortic tissue from Male 10-week-old C57BL/6J mice after AAA-induction with porcine pancreatic elastase, compared with sham-operated saline-injected mice. One day after AAA-induction, the mice were injected intraperitoneally with either lentiviral packaged miR-24 antagomir (anti-miR-24) or miR-24 mimic (pre-miR-24), or a scrambled microRNA control (scr-miR). Aortic samples were obtained 7 days after operation. The goal was to examine gene expression in developing AAA in this model, and to compare the effects of scr-miR, anti-miR-24 and pre-miR-24. Four condition experiment, one infrarenal aorta per array. Sham vs. scr-miR-PPE vs. anti-miR-24-PPE vs. pre-miR-24-PPE, all harvested at Day 7 post-operatively. After QC, the final analysis group (uploaded here) consisted of 18 arrays: Sham-Saline-treated (4 arrays), scr-miR-PPE-treated (5 arrays); pre-miR-24-PPE-treated (3 arrays); and anti-miR-24-PPE-treated (6 arrays).

Abdominal Aortic Aneurysm in C57BL/6J Mice - Male and Female PPE vs. Sham Day 7

Project description:Transcriptional profiling of infrarenal aorta from male and female mice (10-weeks old, C57BL/6J), treated with either porcine pancreatic elastase (PPE) local infusion or sham operation (saline infusion). Samples harvested 7 days after treatment. Goal was to examine gene expression in AAA in this model in both genders. Surgical protocol is as described in PMCID: PMC3148686/PMID: 19629030.

RNA-sequencing of abdominal aortic aneurysm (AAA) and control abdominal aorta tissues

Project description:Abdominal aortic aneurysm (AAA) is a permanent segmental dilatation of the abdominal aorta, contributing to a high mortality once rupture. We performed RNA-sequencing analysis of abdominal aorta tissues from 14 participants, including seven patients with AAA and seven control individuals.

Differential gene expression in human abdominal aortic aneurysm and atherosclerosis

Project description:The aim of this study was to assess the relative gene expression in human AAA and AOD. Genome-wide expression analysis of abdominal aortic aneurysm (AAA) and aortic occlusive disease (AOD) specimens obtained from 20 patients with small AAA (mean maximum aortic diameter=54.3±2.3 mm), 29 patients with large AAA (mean maximum aortic diameter=68.4±14.3 mm), and 9 AOD patients (mean maximum aortic diameter=19.6±2.6 mm). Relative aortic gene expression was compared with that of 10 control aortic specimen of organ donors.
