Project description:Transcription factro-EB (TFEB) is a master gene for autophagy and lysosome biogenesis We used microarrays to detail the gene expression in TFEB-overexpressing vascular smooth muscle cells identified distinct classes of TFEB-regulated genes.
Project description:Vascular mineralization is a carefully orchestrated process, regulated by a number of promoters and inhibitors that function to ensure effective hydroxyapatite formation. Here we sought to identify new regulators of this process through a time series microarray analysis of mineralising primary vascular smooth muscle cell cultures over a 9 day culture period.
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.

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.
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. LncVSM (AK098656) transfection
