Project description:High-throughput sequencing technique was used to screen the miRNAs which has potential role in the aging delaying effect of olmesartan on human smooth muscle cells. We cultured human vascular smooth muscle cells and used the third to fifth generation cells as unaging cells (Zhengchang-1,-2,-3), natural culture to passage 10 to 15 as aging group samples (Bo-1,-2,-3), and cells treated with olmesartan for the same time as aging group cells as treatment group (bo-ao-1,-2,-3). After collecting cells of each group, RNA was extracted and reversed. After the quality inspection was qualified, miRNA sequencing was carried out. Finally, we confirmed that the miRNA expression profile of human vascular smooth muscle cells changed after olmesartan treatment. This study confirmed that miRNA plays a potential role in the aging process of human smooth muscle cells and that olmesartan may play a role in delaying aging by regulating miRNA expression profile.

Project description:We used a smooth muscle cell-specific mineralocorticoid receptor knockout mouse to generate young and aged MR-intact and SMC-MR-KO aortic miRNA to examine the effect of age on vascular miRNA alterations in the presence and absence of SMC-MR. For more information about the mouse model see: McCurley, A et al. Direct regulation of blood pressure by smooth muscle cell mineralocorticoid receptors. Nat Med. 2012 Sep;18(9):1429-33 Total miRNA was extracted from young (3-4 mo) and aged male (12mo) MR-intact and SMC-MR-KO mice to investigate aging-induced alterations in vascular miRNA expression

Project description:Rapid regeneration of smooth muscle after vascular injury is essential for maintaining proper artery function. The current view holds that pre-existing smooth muscle proliferate and expand in responding to vascular injury, contributing to virtually all new smooth muscle cells. Whether resident vascular stem cells for smooth muscle exist remains controversial and their putative functional role for artery repair and regeneration is elusive. Here we performed cell fate mapping and single cell RNA sequencing to identify Sca1+ vascular stem cells (VSCs) residing in the adventitial layer of artery wall.

Project description:Oxidative stress-dependent genes are defined as those induced or suppressed by H2O2 treatement in rat vascular smooth muscle cells. JNK-induced genes in rat vascular smooth muscle cells are defined as those induced by adenoviruses encoding constitutively active MKK7 (caMKK7) + wild type JNK1 (wtJNK1) and suppressed by adenovirus encoding dominant negative JNK1 (APF). JNK-suppressed genes in rat vascular smooth muscle cells are defined as those suppressed by adenoviruses encoding constitutively active MKK7 (caMKK7) + wild type JNK1 (wtJNK1) and induced by adenovirus encoding dominant negative JNK1 (APF). Adenovirus encoding nuclear localizing GFP was used as a control.

Project description:We report a novel technique to reprogram human fibroblasts into endothelial and smooth muscle cells using partial iPSC reprogramming and chemically defined media. Using appropriate media conditions for differentiation of human pluripotent cells to CD34+ vascular progenitor cells, we show that temporary expression of pluripotent transcription factors and treatment with chemically-defined media, will induce differentiation of human fibroblasts to CD34+ vascular progenitor cells. Sorted CD34+ cells can then be directed to differentiate into vascular endothelial cells expressing a variety of smooth muscle markers. We have assessed the global DNA methylation (Illumina Infinium HD 450K DNA methylationBeadChips) and transcriptional (Illumina HT12v4 Gene Expression Bead Array) profiles of transdifferentiated endothelial cells and smooth muscle, human embryonic stem cell (hESC) and human induced pluripotent stem cell (hiPSC) differentiated CD34+ angioblasts, hESCs, hiPSC, primary smooth muscle and primary human umbilical vein endothelial cells using microarrays.

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.
