Project description:In order to further study the role of circular RNA in the phenotypic transformation of vascular smooth muscle cells (VSMCs), the differential expression profile of circRNA in the phenotypic transition of VSMCs induced by platelet-derived growth factor-BB (PDGF-BB) was screened using chip technology. Vascular smooth muscle cells from rat thoracic aorta were induced with 20ng/ml PDGF-BB as the experimental group and compared with the control group. After induction for 24 hours, the differentially expressed circRNA was screened by circular RNA chip.
Project description:Vascular smooth muscle cells (VSMCs) phenotype switch has been thought to be critical to the development of thoracic aneurysm/dissection. To investigate the function HDAC9 in the regulation of VSMCs phenotype switch, we used siRNA knockdown of HDAC9 in human aortic smooth muscle cells (HASMC)we established Human aortic smooth muscle cells (HASMCs).
Project description: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.
Project description:Transcriptomics analysis of human coronary artery smooth muscle cells cultured in calcium-phosphate medium (CaP) to induce a mineralized extracellular matrix. To study the underlying molecular mechanisms driving vascular calcification, we analyzed the transcriptome of calcium-phosphate calcified human cronary aortic smooth muscle cells on day 3.
Project description:Allele-specific circular chromosome conformation capture sequencing (4C-seq) using the single nucleotide polymorphism rs2836411 as a bait was performed in two cell types: human umibilical vein endothelial cells (HUVECs) and human aortic smooth muscle cells (HASMCs).
Project description:Effects of TRPC1 silencing on whole-transcriptome gene expression were determined in human primary aortic vascular smooth muscle cells using whole-transcriptome gene expression profiling.
