RNA Seq Transcriptomic profiling of PDGF-stimulated primary human aortic smooth muscle cells treated with ORAI1 inhibitor relative to controls

ABSTRACT: Platelet-derived growth factor (PDGF) signalling and the subsequent activation of the calcium ion channel, ORAI1 are critical drivers of pathological remodelling of native vascular smooth muscle cells to proliferative state, which is a process associated with various vascular diseases. This study aims to reveal transcriptional networks altered following ORAI1 inhibition in vascular smooth muscle cells. To study the effect of ORAI1 inhibition on VSMC biology, we performed RNA-Seq analysis of PDGF-stimulated primary human aortic smooth muscle cells treated with either ORAI1 inhibitor, (n=4) or with vehicle (n=4), and investigated the effect of ORAI1 inhibition on the transcriptional response of cells.

Rat vascular smooth muscle cells LC-MS/MS

Project description:Crotonylation of histones is discovered of late as one of post-translational modification that can regulate gene expression. However, the function of crotonylation on non-histone proteins in vascular smooth muscle cells (VSMC) is unclear. Here, we aim to use modification and proteomic analysis to find the cellular characteristic of crotonylated non-histone proteins and the crosstalk with ubiquitinated proteins in vascular smooth muscle cell (VSMC) phenotypic remodeling. We performed modification and proteomic analysis of VSMCs before and after stimulated with platelet-derived growth factor-BB (PDGF-BB). The crotonylated and ubiquitinated pan-antibody was used to enrich the protein and then subjected to high-throughput mass spectrometry analysis. The enrichment analysis was performed within differentially modified proteins in regards to GO terms, KEGG and protein domain.

Thymosin 4 protects against aortic aneurysm via endocytic regulation of growth factor signalling

Project description:Vascular stability and tone are maintained by contractile smooth muscle cells (VSMCs). However, injury-induced growth factors stimulate a contractile-synthetic phenotypic modulation which increases susceptibility to abdominal aortic aneurysm (AAA). As a regulator of embryonic VSMC differentiation, we hypothesised that Thymosin β4 (Tβ4) may function to maintain healthy vasculature throughout postnatal life. This was supported by the identification of an interaction with Low density lipoprotein receptor related protein 1 (LRP1), an endocytic regulator of PDGF-BB signalling and VSMC proliferation. LRP1 variants have been implicated by genome-wide association studies with risk of AAA and other arterial diseases. T4-null mice displayed aortic VSMC and elastin defects, phenocopying LRP1 mutants, and their compromised vascular integrity predisposed to Angiotensin II-induced aneurysm formation. Aneurysmal vessels were characterised by enhanced VSMC phenotypic modulation and augmented platelet-derived growth factor (PDGF) receptor (PDGFR)β signalling. In vitro, enhanced sensitivity to PDGF-BB, upon loss of Tβ4, associated with dysregulated endocytosis, with increased recycling and reduced lysosomal targeting of LRP1-PDGFRβ. Accordingly, the exacerbated aneurysmal phenotype in T4-null mice was rescued upon treatment with the PDGFRβ antagonist, Imatinib. Our study identifies Tβ4 as a key regulator of LRP1 for maintaining vascular health and provides insights into the mechanisms of growth factor-controlled VSMC phenotypic modulation underlying aortic disease progression.

Gene expression profiling regulated by PDGF in pBSMCs

Project description:To explore global molecular changes in smooth muscle in response to PDGFR activation, primary human bladder smooth muscle cells were treated with 1 nM PDGF-BB (hereafter PDGF) for 0, 4 or 24 h. Total RNA were prepared, and analyzed using expression profiling, and subjected to bioinformatic and functional interrogation. To identify molecular signatures of bladder smooth muscle peturbed by PDGF, primary human bladder smooth muscle cells were treated with 1 nM PDGF-BB (hereafter PDGF) for 0, 4 or 24 h.

Comparison of gene expression data between control and tissue specific epicardial PDGF receptor (a and b) knockout embryonic hearts

Project description:Epicardial cells undergo an epithelial-to-mesenchymal transtion (EMT) to generate coronary vascular smooth muscle cells (VSMC) and cardiac fibroblasts. Little is known about the mechanisms regulating EMT or the in vivo signals directing epicardial-derived cell (EPDC) fate. Here, we show that loss of PDGF signaling leads to a disruption in Sox9 expression, and when Sox9 expression was restored in mutant hearts, the EMT defect was rescued. Interestingly, mutants lacking only one of the PDGF genes exhibited a lineage specific requirement for the individual receptors. Loss of PDGFRα resulted in a deficit in cardiac fibroblast formation, while cVSMC development was unperturbed. Conversely, PDGFRβ was required for cVSMC development but not cardiac fibroblast development. Combined, our data demonstrate a novel role for PDGF receptors in epicardial EMT and EPDC development.

The tRNA derived fragments (tRFs) expression profiles in human aortic smooth muscle cells (HASMCs)

Project description:To explore the potential involvement of tRNA derived fragments (tRFs) in the human aortic vascular smooth muscle cells (HASMCs), we conducted tRFs profiling in three pairs of differentiated HASMCs (treated with PBS) and dedifferentiated HASMCs (treated with PDGF-BB 50 ng/ml) by microarray. Our results showed that tRFs were aberrantly expressed in dedifferentiated HASMCs compared with differentiated HASMCs and provided potential targets for novel insights into VSMC differentiation or vascular remodeling diseases.

To examine vascular smooth muscle cells (VSMC) under four conditions

Project description:Vascular calcification is a hallmark of atherosclerosis and end-stage renal disease (ESRD). However, the molecular mechanism of vascular calcification is poorly understood. Diabetes mellitus is increasingly recognized as the most important cause for atherosclerosis and ESRD. Emerging evidence supports the concept that vascular calcification resembles the process of osteogenesis, in which the vascular smooth muscle cells (VSMC) undergo osteochondrogenic differentiation. Recently, we have established an in vitro calcification system with primary mouse VSMC. With the use of osteogenic stimuli, we induced trans-differentiation of primary mouse VSMC into bone-like cells. Interestingly stroptozotocin (STZ), O-GlcNAcase inhibitor and a drug that has been used to induce diabetes in mice, was able to induce calcification of VSMC and the expression of the osteogenic transcription factor Runx2, suggesting glycosylation may be involved in regulation of Runx2. We have reported an essential role of Runx2 in oxidative stress-induce VSMC calcification and have recently generated a tissue specific mouse with Runx2 ablation in smooth muscle cells. Therefore, we will use STZ and other relevant reagents in the glucose synthesis/metabolism pathways as stimuli for VSMC calcification to characterize the glycogene profiles during VSMC calcification. Results from VSMC of Runx2 knockout mice will be compared with those from control mice to determine the regulation of calcification-associated glycogenes by Runx2 in response to STZ. These studies will provide foundation for further mechanistic studies and may lead to identification of novel strategies and targets for diabetes-induced vascular calcification. To examine vascular smooth muscle cells (VSMC) under two conditions: 1) wild-type VSMC differentiated into bone-like cells with osteogenic media, 2) wild-type VSMC treated with STZ and osteogenic media
