Project description:Single-cell RNA sequencing (scRNA-seq) was performed on the infrarenal abdominal aortas from C57BL/6J mice at days 7 and 14 post periadventitial elastase-induced AAA or days 14 post periadventitial heat-inactive elastase incubation. This study report the changes of cellular subpopulations, fractions and transcriptomic profiles in response to elastase-induced AAA model.
Project description:Dissecting abdominal aortic aneurysm (AAA) is a life-threatening condition characterized by medial layer degeneration of the abdominal aorta. Complex, complicated, and extremely heterogeneous diseases like dissecting AAAs severely limit our ability to understand it. A thorough understanding of cell types and signaling pathways associated with the initiation and progression of dissecting AAA is essential for the development of medical therapy. Single-cell RNA sequencing (scRNA-seq) was performed on the abdominal aortas from ApoE-/- mice at days 28 post-Angiotensin II-induced mouse dissecting AAAs. According to the Angiotensin II-induced dissecting AAA model described in this study, alterations in cellular subpopulations, fractions, and transcriptome profiles are present.
Project description:We performed single-cell RNA sequencing (scRNA-seq) on infrarenal abdominal aortas from C57BL/6J mice after perivascular CaCl2 treatment. Infrarenal abdominal aortas were collected four days after AAA induction and processed for sequencing. These data provide high-resolution insight into the complexity and heterogeneity of mouse AAA.
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.
Project description:Inflammation is still a crucial factor in the development of abdominal aortic aneurysm (AAA). The CD45+ cell population of elastase-induced murine AAA was deconstructed at the single-cell level using the single-cell RNA (scRNA) transcriptomic technique.
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.

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.
