Abstract
Calcium-sensing receptor (CaSR), a family C G-protein-coupled receptor, plays a crucial role in regulating calcium homeostasis by sensing small concentration changes of extracellular Ca2+, Mg2+, amino acids (e.g., L-Trp and L-Phe), small peptides, anions (e.g., HCO3 - and PO4 3-), and pH. CaSR-mediated intracellular Ca2+ signaling regulates a diverse set of cellular processes including gene transcription, cell proliferation, differentiation, apoptosis, muscle contraction, and neuronal transmission. Dysfunction of CaSR with mutations results in diseases such as autosomal dominant hypocalcemia, familial hypocalciuric hypercalcemia, and neonatal severe hyperparathyroidism. CaSR also influences calciotropic disorders, such as osteoporosis, and noncalciotropic disorders, such as cancer, Alzheimer's disease, and pulmonary arterial hypertension. This study first reviews recent advances in biochemical and structural determination of the framework of CaSR and its interaction sites with natural ligands, as well as exogenous positive allosteric modulators and negative allosteric modulators. The establishment of the first CaSR protein-protein interactome network revealed 94 novel players involved in protein processing in endoplasmic reticulum, trafficking, cell surface expression, endocytosis, degradation, and signaling pathways. The roles of these proteins in Ca2+-dependent cellular physiological processes and in CaSR-dependent cellular signaling provide new insights into the molecular basis of diseases caused by CaSR mutations and dysregulated CaSR activity caused by its protein interactors and facilitate the design of therapeutic agents that target CaSR and other family C G-protein-coupled receptors.

Heliyon 2023; 9:e15286. [PMID: 37187908 PMCID: PMC10176032 DOI: 10.1016/j.heliyon.2023.e15286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 03/21/2023] [Accepted: 03/31/2023] [Indexed: 05/17/2023] Open
Abstract
Purpose Explore the transcription change of brain ischemia and reperfusion injury after deep hypothermic low flow. Method The data from PRJNA739516 and GSE104036 were obtained for the differentially expressed genes identification, functional enrichment analysis, gene set enrichment analysis, protein-protein interaction construction and hub gene identification. Oxygen and glucose deprivation model was set to validate the hub gene and explore the detailed brain injury mechanism. Result Interleukin, immunological response, NF-κB signaling pathway, G protein-coupled receptor signaling pathway and NLRP inflammatory are functional pathway were enriched in differentially expressed genes analysis. Sucnr1, Casr, Cxcr4, C5ar1, Tas2r41, Tas2r60 and Hcar2 were identified and verified in the OGD model. Knocking down GPR91 reduces the inflammatory response after OGD and GPR91 may be involved in the inflammatory pre-reaction through the synergistic activation of NF-κB, NLRP3, and IL-1β respectively. Conclusion Our study found that Interleukin, immunological response, NF-κB signaling pathway, G protein-coupled receptor signaling pathway and NLRP inflammatory are all associated with brain ischemia and reperfusion injury after deep hypothermic low flow and GPR91 can activate NF-κB/NLRP3 pathway and trigger the release of IL-1β in this progress.

Abstract
Poultry is vulnerable to bone problems throughout their lives or production period due to rapid growth in broilers and the active laying cycle in layers. The calcium-sensing receptor (CaSR) is important in calcium and bone metabolism. The objective of this study was to investigate the effect of the CaSR ligand (l-Trp) and 1,25-dihydroxycholecalciferol (1,25OHD3) on the regulation of proliferation and osteogenic differentiation of chicken mesenchymal stem cells (MSCs) isolated from the compact bones of 14-day-old Ross 308 chickens and Dekalb pullets, which can provide cell-based evidence for the prevention or alleviation of skeletal disorders in the poultry industry. First, the dose- (0, 0.5, 1, 2, 5, 10, and 15 mM) and time-effects (0, 7, and 14 days) of l-Trp on the proliferation and osteogenic differentiation in chicken MSCs were investigated. The 5 mM l-Trp had a balanced effect between proliferation and osteogenic differentiation in broiler and layer MSCs when differentiated for 7 days. The broiler and layer MSCs were then treated with (1) osteogenic medium, osteogenic medium supplemented with (2) 1 nM 1,25OHD3, (3) 2.5 mM Ca2+, (4) 2.5 mM Ca2+ + 5 mM l-Trp and (5) 2.5 mM Ca2+ + 5 mM l-Trp + 1 μM NPS-2143, separately for 7 days. Results showed that the 5 mM l-Trp significantly inhibited the proliferation of broiler and layer MSCs on day 7 (P < 0.05), but 1 nM 1,25OHD3 significantly promoted the proliferation of layer MSCs (P < 0.05). Only the 2.5 mM Ca2+ + 5 mM l-Trp group significantly increased the mineralization process during osteogenic differentiation (P < 0.05), and this treatment also significantly upregulated the mRNA expression of the vitamin D receptor (VDR), β-catenin, and osteogenesis genes in broiler MSCs (P < 0.05). The osteogenic differentiation process in layer MSCs was faster than that in broiler MSCs. In layer MSCs, Ca2+ alone significantly facilitated mineralization and ALP activity after 7-day osteogenic differentiation (P < 0.05). However, the 5 mM l-Trp significantly inhibited the differentiation and mineralization process by downregulating the mRNA expression of CaSR, VDR, β-catenin, and osteogenic genes (P < 0.05) in layer MSCs. Taken together, l-Trp and 1,25OHD3 can regulate proliferation and osteogenic differentiation in both broiler and layer MSCs depending on the dose, treatment time, and cell proliferation and differentiation stages.

Abstract
Skeletal muscle has an outstanding capacity for regeneration in response to injuries, but there are disorders in which this process is seriously impaired, such as sarcopenia. Pharmacological treatments to restore muscle trophism are not available, therefore, the identification of suitable therapeutic targets that could be useful for the treatment of skeletal reduced myogenesis is highly desirable. In this in vitro study, we explored the expression and function of the calcium-sensing receptor (CaSR) in human skeletal muscle tissues and their derived satellite cells. The results obtained from analyses with various techniques of gene and protein CaSR expression and of its secondary messengers in response to calcium (Ca2+) and CaSR drugs have demonstrated that this receptor is not present in human skeletal muscle tissues, neither in the established satellite cells, nor during in vitro myogenic differentiation. Taken together, our data suggest that, although CaSR is a very important drug target in physiology and pathology, this receptor probably does not have any physiological role in skeletal muscle in normal conditions.

Abstract
The calcium Sensing Receptor (CaSR) is a cell surface receptor belonging to the family of G-protein coupled receptors. CaSR is mainly expressed by parathyroid glands, kidneys, bone, skin, adipose tissue, the gut, the nervous system, and the cardiovascular system. The receptor, as its name implies is involved in sensing calcium fluctuations in the extracellular matrix of cells, thereby having a major impact on the mineral homeostasis in humans. Besides calcium ions, the receptor is also activated by other di- and tri-valent cations, polypeptides, polyamines, antibiotics, calcilytics and calcimimetics, which upon binding induce intracellular signaling pathways. Recent studies have demonstrated that CaSR influences a wide variety of cells and processes that are involved in inflammation, the cardiovascular system, such as vascular calcification, atherosclerosis, myocardial infarction, hypertension, and obesity. Therefore, in this review, the current understanding of the role that CaSR plays in inflammation and its consequences on the cardiovascular system will be highlighted.
