Gut microbiota dysbiosis has been implicated in pulmonary arterial hypertension (PAH). However, most studies have focused on the bacterial community and the exact role and mechanisms of multi-kingdom gut microbiota, including bacteria, archaea and fungi in PAH remains largely unclear. Idiopathic ...

Microarray analysis of peripheral blood mononuclear (PBMC) cells in pulmonary arterial hypertension.
ORGANISM(S): Homo sapiens 
Although multiple gene and protein expression have been extensively profiled in human pulmonary arterial hypertension (PAH), the mechanism for the development and progression of pulmonary hypertension remains elusive. Analysis of the global metabolomic heterogeneity within the pulmonary vascular sy...

miRNAs have been proved to participate in the regulation of proliferation and apoptosis in many diseases,we consider there may be associations between miRNAs and development of pulmonary arterial hypertension (PAH). Previous studies have revealed that several miRNAs participated in the regulation of...

Endothelial cell (EC) dysfunction plays a key role in the pathogenesis of pulmonary arterial hypertension (PAH). To avoid cell cultures and whole lung tissue samples, we have, for the first time, used CD31 antibody coated magnetic beads in conjunction with genome scale RNA expression microarrays to ...
ORGANISM(S): Rattus norvegicus 
Vascular remodeling in pulmonary arterial hypertension (PAH) involves proliferation and migration of endothelial and smooth muscle cells, leading to obliterative vascular lesions. Previous studies have indicated that the endothelial cell proliferation is quasi-neoplastic, with evidence of monoclonal...
ORGANISM(S): Homo sapiens 
Pulmonary arterial hypertension (PAH) is a severe and incurable pulmonary vascular disease. One of the primary origins of PAH is pulmonary endothelial dysfunction leading to vasoconstriction, aberrant angiogenesis and smooth muscle cell proliferation, endothelial-to-mesenchymal transition, thrombosi...

Rationale: Schistosomiasis is one of the most common causes of pulmonary arterial hypertension worldwide, but the pathogenic mechanism by which the host inflammatory response contributes to vascular remodeling is unknown. We sought to identify signaling pathways that play protective or pathogenic ro...
ORGANISM(S): Mus musculus 
Pulmonary arterial hypertension (PAH) is a vascular remodeling disease characterized by enhanced pulmonary artery smooth muscle cell (PASMC) proliferation and suppressed apoptosis. Downregulation of the BMPR2 gene along with activation of the transcription factor NFAT have been implicated in the mai...
