[PMID: 38857682 DOI: 10.1016/j.ejphar.2024.176717] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 05/07/2024] [Accepted: 06/05/2024] [Indexed: 06/12/2024]
Abstract
The Ca2+-sensing receptor (CaSR) is a G-protein-coupled receptor activated by elevated concentrations of extracellular Ca2+, and was initially known for its regulation of parathyroid hormone (PTH) release. Ubiquitous expression of CaSR in different tissues and organs was later noted and CaSR participation in various physiological functions was demonstrated. Accumulating evidence has suggested that CaSR functionally interacts with transient receptor potential (TRP) channels, which are mostly non-selective cation channels involved in sensing temperature, pain and stress. This review describes the interactions of CaSR with TRP channels in diverse cell types to trigger a variety of biological responses. CaSR has been known to interact with different types of G proteins. Possible involvements of G proteins, other signaling and scaffolding protein intermediates in CaSR-TRP interaction are discussed. In addition, an attempt will be made to extend the current understanding of biased agonism of CaSR.

The role of calcium-sensing receptor in ginsenoside Rg1 promoting reendothelialization to inhibit intimal hyperplasia after balloon injury. Biomed Pharmacother 2023; 163:114843. [PMID: 37201261 DOI: 10.1016/j.biopha.2023.114843] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 04/25/2023] [Accepted: 05/04/2023] [Indexed: 05/20/2023] Open
Abstract
Calcium-sensing receptor (CaSR) is a G protein-coupled receptor, widely distributed in various tissues, including vascular endothelial cells and smooth muscle cells, which plays an important role in the migration and homing of stem/progenitor cells and the proliferation of tissue cells. Restenosis after Percutaneous coronary intervention (PCI) seriously affects its prognosis and application. Our previous research has found that ginsenoside Rg1 (GS-Rg1) can inhibit the occurrence of restenosis after balloon injury of the common carotid artery in rats, but the mechanism is still unclear. In this study, it was found that GS-Rg1 (4, 8, 16 mg/kg) inhibited vascular restenosis caused by balloon injury, and mobilize endothelial progenitor cells (EPCs) to promote reendothelialization and inhibit intimal hyperplasia, which significantly reduced after administration of CaSR antagonist NPS 2143. Interestingly, CaSR and its downstream JNK, P38 were highly expressed in the proliferative intima and participated in the abnormal proliferation of vascular smooth muscle cells mediated by smooth muscle progenitor cells (SMPCs). GS-Rg1 inhibited intimal hyperplasia, while it decreased the expression of CaSR, JNK, and P38. This might relate to the distribution of CaSR and the facilitation of GS-Rg1 on the vascular endothelial repair. It is concluded that CaSR plays a key role in GS-Rg1 promoting reendothelialization to inhibit intimal hyperplasia after balloon Injury.

Abstract
Populations that are born and raised at high altitude develop under conditions of chronic developmental hypoxia (CDH), which results in pulmonary adaptations of increased lung volume and diffusion capacity to increase gas exchange. It is not clear how CDH may alter allergic inflammation in the lung. In this study, we sought to characterize the impact of CDH on immune cell populations in the rat lung during a murine model of asthma. Rats were bred and raised in either hypoxic (15% oxygen, CDH) or normobaric room air (20% oxygen). At 3-weeks of age, animals were sensitized to ovalbumin (OVA) or physiologic saline (phosphate-buffered saline [PBS]) as a control, followed by three consecutive days of intra-nasal OVA or PBS at 6-weeks of age. We then assessed airway reactivity and allergic-associated cytokine levels. This was followed by single-cell transcriptomic profiling of lung cell populations. In scRNA-seq analysis, we assessed differentially expressed genes, differentially enriched functional pathways, immune cell exhaustion/activation markers, and immune cell secretory products. Our results show that while OVA heightened airway reactivity, CDH suppressed airway reactivity in OVA-challenged and control animals. Through scRNA-seq analysis, we further demonstrate that CDH alters the transcriptional landscape in the lung and alters transcriptional programs in immune cells. These data define CDH-dependent changes in the lung that impact airway reactivity.

Deletion of classical transient receptor potential 1, 3 and 6 alters pulmonary vasoconstriction in chronic hypoxia-induced pulmonary hypertension in mice. Front Physiol 2022; 13:1080875. [PMID: 36569761 PMCID: PMC9768328 DOI: 10.3389/fphys.2022.1080875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 11/21/2022] [Indexed: 12/12/2022] Open
Abstract
Chronic hypoxia-induced pulmonary hypertension (CHPH) is a severe disease that is characterized by increased proliferation and migration of pulmonary arterial smooth muscle cells (PASMCs) leading to pulmonary vascular remodeling. The resulting increase in pulmonary vascular resistance (PVR) causes right ventricular hypertrophy and ultimately right heart failure. In addition, increased PVR can also be a consequence of hypoxic pulmonary vasoconstriction (HPV) under generalized hypoxia. Increased proliferation and migration of PASMCs are often associated with high intracellular Ca2+ concentration. Recent publications suggest that Ca2+-permeable nonselective classical transient receptor potential (TRPC) proteins-especially TRPC1 and 6-are crucially involved in acute and sustained hypoxic responses and the pathogenesis of CHPH. The aim of our study was to investigate whether the simultaneous deletion of TRPC proteins 1, 3 and 6 protects against CHPH-development and affects HPV in mice. We used a mouse model of chronic hypoxia as well as isolated, ventilated and perfused mouse lungs and PASMC cell cultures. Although right ventricular systolic pressure as well as echocardiographically assessed PVR and right ventricular wall thickness (RVWT) were lower in TRPC1, 3, 6-deficient mice, these changes were not related to a decreased degree of pulmonary vascular muscularization and a reduced proliferation of PASMCs. However, both acute and sustained HPV were almost absent in the TRPC1, 3, 6-deficient mice and their vasoconstrictor response upon KCl application was reduced. This was further validated by myographical experiments. Our data revealed that 1) TRPC1, 3, 6-deficient mice are partially protected against development of CHPH, 2) these changes may be caused by diminished HPV and not an altered pulmonary vascular remodeling.

Abstract
Pulmonary arterial hypertension (PAH) is an intractable vascular disease characterized by
a progressive increase in pulmonary vascular resistance caused by pulmonary vascular
remodeling, which ultimately leads to right-sided heart failure. PAH remains incurable,
despite the development of PAH-targeted therapeutics centered on pulmonary artery
relaxants. It is necessary to identify the target molecules that contribute to pulmonary
artery remodeling. Transient receptor potential (TRP) channels have been suggested to
modulate pulmonary artery remodeling. Our study focused on the transient receptor
potential ion channel subfamily M, member 7, or the TRPM7 channel, which modulates
endothelial-to-mesenchymal transition and smooth muscle proliferation in the pulmonary
artery. In this review, we summarize the role and expression profile of TRPM7 channels in
PAH progression and discuss TRPM7 channels as possible therapeutic targets. In addition,
we discuss the therapeutic effect of a Chinese herbal medicine, Ophiocordyceps
sinensis (OCS), on PAH progression, which partly involves TRPM7 inhibition.
