Microarray to identify miR-143 targets in pulmonary artery smooth muscle cells.

Project description:Pulmonary artery smooth muscle cells were either mock transfected, transfected with scramble control or transfected with pre-miR-143. After 24 hours the cells were harvested with Qiazol and processed for a microarray experiment. The experiment was performed in order to identify potential targets of miR-143.

Microarray-based gene expression of rabbit basilar artery smooth muscle cells exposed to hemodynamic insult

Project description:High-flow causes the remodeling of arteries, in which smooth muscle cells play an important role. To know the profile of smooth muscle gene expression under high-flow conditions in vivo, flow of rabbit basilar artery was increased by ligation of both common carotid arteries. Microarrays were performed to profile the gene expression of smooth muscle cells isolated from rabbit basilar artery. Expression profiles indicate 43603 differentially expressed genes in smooth muscle cells exposed to high-flow insult compared with the sham control, of which 1470 genes were upregulated and 780 genes downregulated using 2 fold-changes and P<0.05 as a cut-off. Bilateral common carotid arteries of female New Zealand White rabbits were ligated to increase vascular flow.The control group was performed the same procedure to expose the CCAs without ligation. Rabbits were euthanized at day 5 after ligation or exposure of bilateral CCAs in both groups (n=3 for each group). The rabbits used and all procedures in this study were approved by the local Institutional Animal Care and Use Committee. Smooth muscle cells were isolated. After euthanization of rabbits, the whole basilar arteries were removed. The arteries were cleaned in PBS buffer,cannulated and perfused at a constant flow with a cocktail which contains PBS and 0.4 mg/ml elastase (Sigma) and 1 mg/ml collagenase (type 1A, Sigma). After an incubation time of 45 min, the tissue left was removed and stored in PBS. SMCs were released from the artery by trituration. Then Total RNA was extracted and gene chip tests were performed.

Endothelial cell senescence exacerbates pulmonary hypertension by inducing juxtacrine Notch signaling in smooth muscle cells

Project description:Pulmonary arterial hypertension (PAH) is a fatal disease characterized by a progressive increase in pulmonary artery pressure caused by pathological pulmonary artery remodeling. Here, we show that endothelial cell (EC) senescence plays a negative role in pulmonary hypertension via juxtacrine interaction with smooth muscle cells (SMCs). By using EC-specific progeroid mice that we recently generated, we discovered that EC progeria deteriorated vascular remodeling in the lungs, and exacerbated pulmonary hypertension in mice exposed to chronic hypoxia. Mechanistically, senescent ECs overexpressed Notch ligands, which resulted in increased Notch signaling and activated proliferation and migration capacities in neighboring SMCs. Pharmacological inhibition of Notch signaling reduced the effects of senescent ECs on SMCs functions in vitro, and improved the worsened pulmonary hypertension in EC-specific progeroid mice in vivo. Our findings show that EC senescence is a critical disease-modifying factor in PAH and that EC-mediated Notch signaling is a pharmacotherapeutic target for the treatment of PAH, particularly in the elderly.
