Angiotensin II-induced long non-coding RNA Alivec regulates chondrogenesis in vascular smooth muscle cells

Project description:Alivec is a novel lncRNA found to be upregulated by Ang II stimulation in rat vascular smooth muscle cells (RVSMCs). The regulatory mechanisms of rat Alivec have not been reported so far. We used microarrays to investigate Alivec-mediated global gene expression and identified distinct classes of up- and down-regulated genes.

Angiotensin II regulated gene expression in rat primary vascular smooth muscle cells (VSMC)

Project description:Atherosclerosis is one of the causative factors leading to the development of cardiovascular disease. Angiotensin II (AngII) is implicated in the pathological processes underlying atherosclerosis. We investigated the AngII regulated gene expression in primary vascular smooth muscle cells (VSMC). VSMCs were isolated from the thoracic aorta of male Wistar rats. Serum deprived VSMCs were stimulated with 100 nM AngII or vehicle for 2 hours, then RNA-Sequencing was carried out.

Gene expression profiling using microarray in rat aortic vascular smooth muscle cells in response to Angiotensin II stimulation

Project description:Increased level of the hormone angiotensin II (AngII) contributes to the development of several cardiovascular issues, including atherosclerosis, vascular remodeling, and hypertension by altering gene expression. In our study, we use microarray analysis to investigate the effect of AngII on primary vascular smooth muscle cells derived from rat thoracic aorta. We have identified genes upregulated in response to AngII and are investigating their contribution to these cardiovascular conditions.

Expression data from Angiotensin II (Ang II)-treated Rat Vascular Smooth Muscle Cells (RVSMC)

Project description:Angiotensin II (Ang II)-mediated vascular smooth muscle cells (VSMC) dysfunction plays a critical role in cardiovascular diseases. However, the gene expression in this process is unclear. We used Rat Affymetrix gene array to profile Ang II-regulated gene in RVSMC and evaluated their role in VSMC dysfunction. Examined 4 samples of Rat VSMC in triplicate. Control (without Ang II treatment) and 3 samples treated with Ang II for 6h, 12h, and 24h. Compared the changes in gene expression in Ang II treated samples relative to control samples.

LncVSM (AK098656) up/down-regulation in Vascular Smooth Muscle cells

Project description:Long non-coding RNAs (LncRNAs) in hypertensives and their mechanisms in regulating blood pressure still remain unexplored. The aim of present study is to construct the profiles of LncRNAs in blood of patients with essential hypertension and healthy controls. Methods and results, LncRNA microarray identified up-regulated, anddown-regulated LncRNAs, in hypertensives compared to their healthy controls. Among them, one vascular smooth muscle (VSM)-specific LncRNA AK096656 (LncVSM) was quantitated in plasma of patients with hypertension and their healthy controls using the real-time qRT-PCR. LncVSM shows specific expression in human arterial vascular smooth muscle cells (HASMCs) and promote its proliferation and migration. Expression profiles and Ingenuity Pathway Analysis (IPA) revealed that LncVSM activated Renin-Angiotensin Signaling (RAS). the overexpression of LncVSM would result hypertension related complications.

LRP1 in Vascular Remodeling and Angiotensin Signaling

Project description:Vascular smooth muscle cells (vSMC) exert a critical role in sensing and maintaining vascular integrity. These cells abundantly express the low-density lipoprotein receptor-related protein 1 (LRP1), a large endocytic and signaling receptor that recognizes numerous ligands including ApoE-rich lipoproteins, proteases, and protease-inhibitor complexes. We observed the spontaneous formation of aneurysms in the superior mesenteric artery (SMA) of both male and female mice in which LRP1 was genetically deleted in v SMC (smLRP1-/- mice). Quantitative proteomics revealed elevated abundance of several proteins in smLRP1-/- mice that are known to be induced by angiotensin II (AngII)-mediated signaling, suggesting that this pathway is dysregulated. Administration of losartan, an AngII type I receptor antagonist, or an angiotensinogen antisense oligonucleotide to reduce plasma angiotensinogen concentrations restored the normal SMA phenotype in smLRP1-/- mice and prevented aneurysm formation. Additionally, employing a vascular injury model, we noted excessive vascular remodeling and neointima formation in smLRP1-/- mice that was restored by losartan administration. Together, these findings reveal that LRP1 regulates vascular integrity and remodeling of the SMA by attenuating excessive AngII-mediated signaling.

High-throughput sequencing of endogenous small RNAs from rat vascular smooth muscle cells with and without Angiotensin II stimulation

Project description:Angiotensin II (Ang II)-mediated vascular smooth muscle cells (VSMC) dysfunction plays a critical role in cardiovascular diseases. However, the role of microRNAs (miRNAs) in this process is unclear. We used small RNA deep sequencing to profile Ang II-regulated miRNAs in rat VSMC and evaluated their role in VSMC dysfunction. Sequencing results revealed several Ang II-responsive miRNAs and bioinformatics analysis showed that their predicted targets can modulate biological processes relevant to cardiovascular diseases.

JOSD2 inhibits angiotensin II-induced vascular remodeling by deubiquitinating and stabilizing SMAD7

Project description:Increased level of angiotensin II (Ang II) plays a central role in the development of hypertensive vascular remodeling. Here, we identify the deubiquitinating enzyme JOSD2 as a protective factor and investigate its molecular mechanism in Ang II-induced vascular remodeling. Firstly, we found that JOSD2 was up-regulated in aortic smooth muscle cells but not endothelial cells of Ang II-challenged mouse vascular tissues. Whole-body knockout of JOSD2 significantly deteriorated Ang II-induced vascular remodeling in mice. Conversely, Ang II-induced vascular remodeling was reversed by VSMC-specific JOSD2 overexpression. In vitro, JOSD2 deficiency aggravated the fibrosis, proliferation, and migration induced by Ang II in vascular smooth muscle cells (VSMCs), while these changes were reversed by JOSD2 overexpression. RNA-seq analysis showed that the protective effects of JOSD2 in VSMCs were related to TGFβ-SMAD pathway. Furthermore, the LC-MS/MS analysis identified SMAD7, a negative regulator in TGFβ-SMAD pathway, as the substrate of JOSD2. JOSD2 specifically bound to the MH1 domain of SMAD7 to removed K48-linked Ub chains of SMAD7 at lysine 220 to sustain SMAD7 stability. Taken together, our finding reveals that JOSD2-SMAD7 axis is critical for relieving Ang II-induced vascular remodeling and JOSD2 maybe a novel and potential therapeutic target for hypertensive vascular remodeling.
