Project description:As the critical step of pathogenesis during hypoxic pulmonary arterial hypertension (PAH) vascular remodeling is closely associated with pulmonary arterial smooth muscle cell (PASMC) alterations induced by hypoxia that include persistent vasoconstriction, abnormal proliferation and PASMC resistance to apoptosis. Quercetin is a flavonoid compound extracted from green plants that inhibits proliferation, induces apoptosis, arrests the cell cycle, and rescues the constriction of PASMCs, but the underlying mechanisms remain poorly understood. In this study, we used a commercial Agilent Whole Rat Genome Oligo Microarray to determine the overall transcriptional response of PASMCs in response to exposure to hypoxia and the optimal concentration of quercetin. Hypoxia induced the upregulation of 1694 genes and the downregulation of 2091 genes compared with the normoxia group. Quercetin treatment resulted in 1790 upregulated genes and 1450 downregulated genes. Quercetin is known to cause differential expression of several of these genes that are known to promote proliferation, induce apoptosis (Cycs, Ppp3ca, Prkar2b, Akt3, Ppp3cc, Il1rap, Ntrk1), arrest the cell cycle (Chek2, Cdkn1c, Gadd45b, Stag2, Anapc7, Orc1, Ccne1, Myc3, Skp1, Espl1, Cdc45, Mcm4), and rescue PASMC constriction (Ramp1, Ramp3, Adcy5, Gnas, Prkcd, Itpr3, Adra1d, Calm1, Npr1, Avpr1a, Ednra, Adcy8). Real-time quantitative RT-PCR was performed to verify the microarray results. In conclusion, quercetin altered the expression profile of many genes regulated by hypoxia in PASMCs, which helps to further explore the mechanism of the effects of quercetin treatment on hypoxic PAH.

Project description:NOX1 is a catalytic subunit of nonphagocytic NADPH oxidase, mainly localized to smooth muscle cells in the vasculature. We investigated the pathology underlying the pulmonary arterial hypertension-like phenotype demonstrated in mice deficient in the Nox1 gene (Nox1-KO). Spontaneous enlargement and hypertrophy of the right ventricle, accompanied by hypertrophy of pulmonary vessels, were demonstrated in Nox1-KO at 9-18 weeks of age. Since an increased number of ?-smooth muscle actin-positive vessels was observed in Nox1-KO, pulmonary arterial smooth muscle cells (PASMCs) were isolated and characterized by flow cytometry and TUNEL staining. In Nox1-/Y PASMC, the number of apoptotic cells was significantly reduced without any change in the expression of endothelin-1, and hypoxia-inducible factors HIF-1a and HIF-2a, factors implicated in the pathogenesis of PAH. microRNA expression profiling of mouse pulmonary arterial smooth muscle cells in wild-type and NOX1-KO was analyzed. Pulmonary arterial smooth muscle cells were harvested form 3 mice.

Spontaneous enlargement and hypertrophy of the right ventricle, accompanied by hypertrophy of pulmonary vessels, were demonstrated in Nox1-KO at 9-18 weeks of age. Since an increased number of α-smooth muscle actin-positive vessels was observed in Nox1-KO, pulmonary arterial smooth muscle cells (PASMCs) were isolated and characterized by flow cytometry and TUNEL staining. In Nox1-/Y PASMC, the number of apoptotic cells was significantly reduced without any change in the expression of endothelin-1, and hypoxia-inducible factors HIF-1a and HIF-2a, factors implicated in the pathogenesis of PAH. Transcriptional profiling of mouse pulmonary arterial smooth muscle cells in wild-type and NOX1-KO was analyzed. Pulmonary arterial smooth muscle cells were harvested from 3 mice.

Project description:Idiopathic pulmonary arterial hypertension (IPAH) is characterized by medial hypertrophy due to pulmonary arterial smooth muscle cell (paSMC) hyperplasia. Interleukin (IL)-13 is a potent regulator of tissue fibrosis and remodelling, and its effects are dependent on the cell-type specific expression of the IL-13 receptor isotypes IL-4Rα, IL-13Rα1, and IL-13Rα2. In order to identify the possible mechanism how IL-13 can exert its antiproliferative effect on paSMC microarray analysis was performed. For this purpose paSMC were stimulated with IL-13(10ng/ml) for 2h and 6h, respectively and subjected to microarray analysis. Comparison of stimulated versus unstimulated cells. 3 biological replicates, 2 time points

Project description:Pulmonary artery smooth muscle cells were either mock transfected, transfected with scramble control or transfected with pre-miR-143. Then miR-143 enriched exosmes were extracted from the PASMCs and put onto pulmonary arterial endothelial cells. 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.
