Smooth muscle cell reprogramming in aortic aneurysms [RNA-Seq]

ABSTRACT: Smooth muscle cell TGFβ signaling is one of the primary drivers of smooth muscle cell maturation. Inhibition of smooth muscle cell TGFβ signaling in hyperlipidemic mice induces vessel wall inflammation and vessel wall dilation/dissection and leads aortic aneurysm. We performed bulk RNAseq method to examine smooth muscle cell gene expression profile using fresh human tissues from normal aortic media smooth muscle cells and aneurysm aortic media smooth muscle cells.

Smooth muscle cell reprogramming in aortic aneurysms [scRNA-Seq]

Project description:Smooth muscle cell TGFβ signaling is one of the primary drivers of smooth muscle cell maturation. Inhibition of smooth muscle cell TGFβ signaling in hyperlipidemic mice induces vessel wall inflammation and vessel wall dilation/dissection and leads aortic aneurysm. We performed scRNAseq method to examine smooth muscle cell gene expression profile using Apoe and SMC specific TGFbR2 KO in Apoe background mice.

MicroRNA profiling of cells isolated from human abdominal aortic aneurysms. Let-7f, a new potential circulating biomarker

Project description:This study aims to identify and characterize miRNA expression in aneurysmal smooth muscle cells (SMCs) and M1 and M2 macrophages isolated by laser microdissection from human AAA biopsy samples. The aim of this study was to profile (with microarray technology) miRNAs in M1 and M2 macrophages and Smooth muscle cells (SMCs), isolated by laser capture microdissection (LCM). SMCs isolated from control non-aneurysmal aortas were the control group according to which data were normalized. Areas enriched in M1 macrophages, M2 macrophages and smooth muscle cells were microdissected (9.8 [4.7-16.2] mm2) from two different biopsy samples of human abdominal aortic aneurysm. An area enriched in smooth muscle cells was microdissected from two biopsy samples of non aneurysmal abdominal aortas. Each microdissected samples were analyzed independently on microarray. M1 and M2 macrophages and smooth muscle cells expressed in human abdominal aneurysmal aortas were each analyzed in duplicate (each isolated from different human donors of abdominal aortic aneurysm). Analysis of replicated samples of cells were performed on a second microarray. Data were normalized with smooth muscle cells isolated from human abdominal non aneurysmal aortas.

Expression data from mouse aortas

Project description:Aortic aneurysm is a life-threatening cardiovascular disorder due to the predisposition for dissection and rupture. Genetic studies have proved the involvement of the transforming growth factor-β (TGF-β) pathway in aortic aneurysm. Smad4 is the central mediator of canonical TGF-β signaling. However, the exact role of Smad4 confined to the smooth muscle cells (SMCs) in the pathogenesis of aortic aneurysm is largely unknown. Furthermore, whether TGF-β signaling disruption in SMCs could directly trigger aortic wall inflammation remains poorly investigated. Recently, we revealed a pivotal role of smooth muscle Smad4 signaling in maintaining aortic wall homeostasis and protecting against the development of aortic aneurysm and dissection. To evaluate the underlying mechanism by which Smad4 regulate VSMC functions and affects aneurysm formation and development, Smooth muscle specific Smad4 Knockout mice and the control littermate were sacrificed at 6 weeks old, and their aortic ateries were collected.We combined 3-5 vessels for one sample, and 2 samples for each phenotype. Subsequently, a total of 400ng RNA was used following Affymetrix instruction and 2 ug of cRNA were hybridized for 16 hr at 45°. GeneChips were scanned using the Scanner 7G and the data was analyzed with Expression Console using Affymetrix default analysis settings and global scaling as normalization method. RMA analysis was employed to evaluate the gene expression. We used microarrays to detect the global gene expression in the aortic arteries of smooth muscle cell specific Smad4 knockout mice (Smad4-KO)compared with wild type littermates (WT) at 6 weeks old and identified distinct classes of altered genes.

Smooth muscle cell-specific Klf4 deletion in Marfan syndrome aortic root aneurysm

Project description:Aortic smooth muscle cell (SMC) phenotype modulation is a central feature of cell-mediated pathology in Marfan syndrome aortic aneurysm and Klf4 is proposed to contribute to this process. We generated mice with smooth muscle cell-specific Klf4 deletion using an Myh11-creERT2 transgene, induced deletion at 8 weeks and performed single cell RNA sequencing at 24 weeks on whole aortic root tissues.

Endothelial TGFβ signaling drives vascular inflammation and atherosclerosis [scRNA-Seq]

Project description:Endothelial TGFβ signaling is one of the primary drivers of atherosclerosis-associated vascular inflammation. Inhibition of endothelial TGFβ signaling in hyperlipidemic mice reduces vessel wall inflammation and vascular permeability and leads to arrest of disease progression and regression of established lesions. We performed scRNAseq method to examine endothelial cell gene expression profile using Apoe and EC specific TGFbR1/2 KO in Apoe background mice.

Adventitial tertiary lymphoid organs in AAA are a potential source of miRNAs as biomarkers

Project description:This study aims to identify and characterize miRNA expression inATLOs isolated by laser microdissection from human AAA biopsy samples. The aim of this study was to profile (with microarray technology) miRNAs in ATLOs (Adventitial tertiary lymphoid organs), isolated by laser capture microdissection (LCM). Smooth muscle cells (SMCs) isolated from control non-aneurysmal aortas were the control group according to which data were normalized. ATLOs were microdissected (mean 13.5mm2) from two different biopsy samples of human abdominal aortic aneurysm. An area enriched in smooth muscle cells was microdissected from two biopsy samples of non aneurysmal abdominal aortas. Each microdissected samples were analyzed independently on microarray. ATLOs located in human abdominal aneurysmal aortas were each analyzed in duplicate (each isolated from different human donors of abdominal aortic aneurysm). Data were normalized with smooth muscle cells isolated from human abdominal non aneurysmal aortas.

Protein interaction partners of long non-coding RNA NUDT6 in human aortic smooth muscle cells

Project description:The long non-coding RNA NUDT6 was found to be deregulated in abdominal aortic aneurysm (AAA) with higher expression in diseased human tissue specimens versus control aortic tissue. Apart from the already well-studied DNA: RNA interaction as a natural antisense transcript to Fibroblast Growth Factor 2 (FGF2), we were interested in identifying protein interaction partners to unravel further involvement in the pathogenesis and progression of abdominal aortic aneurysm. Therefore, we performed a RNA pulldown experiment using biotinylated NUDT6 and control RNA in human aortic smooth muscle cell lysate to identify further interaction partners.
