Abstract
Pulmonary hypertension (PH) is characterized by elevation of pulmonary arterial pressure and pulmonary vascular resistance. The increased pulmonary arterial pressure and pulmonary vascular resistance due to sustained pulmonary vasoconstriction and pulmonary vascular remodeling can lead to right heart failure and eventual death. A rise in intracellular Ca2+ concentration ([Ca2+]i) and enhanced pulmonary arterial smooth muscle cells (PASMCs) proliferation contribute to pulmonary vasoconstriction and pulmonary vascular remodeling. Recent studies demonstrated that extracellular calcium sensing receptor (CaSR) as a G-protein coupled receptor participates in [Ca2+]i increase induced by hypoxia in the experimental animals of PH and in PH patients. Pharmacological blockade or gene knockout of CaSR significantly attenuates the development of PH. This review will aim to discuss and update the pathogenicity of CaSR attributed to onset and progression in PH.

[PMID: 33378977 DOI: 10.1016/j.biopha.2020.111081] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 11/17/2020] [Accepted: 11/28/2020] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVE A growing evidence demonstrates that inflammation is a major contributor to the pathogenesis of pulmonary arterial hypertension (PAH). However, blocking inflammation has only been shown to be of minor clinical benefit due to a lack of understanding of the precise inflammation present in PAH. Thus, the present study aimed to investigate characteristics of inflammatory process in PAH induced by monocrotaline (MCT) in rats. METHODS Adult male Sprague-Dawley rats received a single dose of MCT (50 mg/kg, ip), and the occurrence of PAH and inflammation biomarkers were measured at 3, 6, 9, 12, 15, 18, 21, 24, 27 and 30 days after MCT injection. RESULTS From the 6th day after the injection of MCT, the mean pulmonary artery pressure gradually increased and doubled on the 30th day, accompanied by right ventricular hypertrophy and pulmonary arterial remodeling in a time-dependent manner. In the first 6 days after MCT treatment, only pro-inflammatory cytokines TNF-α, IL-1β increased, which was defined as acute inflammatory phase, after that, both pro-inflammatory factors TNF-α, IL-1β, IL-6, IL-12 and anti-inflammatory factors Arg1, IL-10, TGF-β increased, which was defined as chronic inflammatory phase. The M1/M2 macrophage ratios in lung and alveolar lavage fluid were elevated on the 6th and 30th day, moreover, which were higher on the 6th than 30th day, and the PI3K/Akt signaling pathway increased along with the progression of PAH and correlated with pro-inflammatory proteins, which revealed also to some extent the characteristics of inflammation of PAH induced by MCT. CONCLUSION The course of PAH induced by MCT injection is progressive with persistent inflammation, which is defined as acute inflammatory phase within 6 days after MCT treatment, after that, is defined as chronic inflammatory phase.

Abstract
Monocrotaline has been widely used to establish an animal model of pulmonary hypertension, most frequently in rats. An important feature of this model resides in the selectivity of monocrotaline injury toward the pulmonary vascular endothelium versus the systemic vasculature when administrated at standard dosage. The toxic metabolite of monocrotaline, monocrotaline pyrrole, is transported by erythrocytes. This study aimed to reveal whether partial pressure of oxygen of blood determined the binding and release of monocrotaline pyrrole from erythrocytes in rats with one subcutaneous injection of monocrotatline at the standard dosage of 60 mg/kg. Our experiments demonstrated that monocrotaline pyrrole bound to and released from erythrocytes at the physiological levels of partial pressure of oxygen in venous and arterial blood, respectively, and then aggregated on pulmonary artery endothelial cells. Monocrotaline pyrrole-induced damage of endothelial cells was also dependent on partial pressure of oxygen. In conclusion, our results demonstrate the importance of oxygen partial pressure on monocrotaline pyrrole binding to erythrocytes and on aggregation and injury of pulmonary endothelial cells. We suggest that these mechanisms contribute to pulmonary selectivity of this toxic injury model of pulmonary hypertension.

Abstract
BACKGROUND Monocrotaline has been widely used to establish an animal model of pulmonary hypertension. The molecular target underlying monocrotaline-induced pulmonary artery endothelial injury and pulmonary hypertension remains unknown. The extracellular calcium-sensing receptor (CaSR) and particularly its extracellular domain hold the potential structural basis for monocrotaline to bind. This study aimed to reveal whether monocrotaline induces pulmonary hypertension by targeting the CaSR. METHODS AND RESULTS Nuclear magnetic resonance screening through WaterLOGSY (water ligand-observed gradient spectroscopy) and saturation transfer difference on protein preparation demonstrated the binding of monocrotaline to the CaSR. Immunocytochemical staining showed colocalization of monocrotaline with the CaSR in cultured pulmonary artery endothelial cells. Cellular thermal shift assay further verified the binding of monocrotaline to the CaSR in pulmonary arteries from monocrotaline-injected rats. Monocrotaline enhanced the assembly of CaSR, triggered the mobilization of calcium signaling, and damaged pulmonary artery endothelial cells in a CaSR-dependent manner. Finally, monocrotaline-induced pulmonary hypertension in rats was significantly attenuated or abolished by the inhibitor, the general or lung knockdown or knockout of CaSR. CONCLUSIONS Monocrotaline aggregates on and activates the CaSR of pulmonary artery endothelial cells to trigger endothelial damage and, ultimately, induces pulmonary hypertension.

Abstract
Covering the literature from mid-2004 until the end of 2011, this review continues a previous literature overview on quantitative (1)H NMR (qHNMR) methodology and its applications in the analysis of natural products. Among the foremost advantages of qHNMR is its accurate function with external calibration, the lack of any requirement for identical reference materials, a high precision and accuracy when properly validated, and an ability to quantitate multiple analytes simultaneously. As a result of the inclusion of over 170 new references, this updated review summarizes a wealth of detailed experiential evidence and newly developed methodology that supports qHNMR as a valuable and unbiased analytical tool for natural product and other areas of research.
