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.

Abstract
Kidney stone disease (nephrolithiasis) is a common problem that can be associated with alterations in urinary solute composition including hypercalciuria. Studies suggest that the prevalence of monogenic kidney stone disorders, including renal tubular acidosis with deafness, Bartter syndrome, primary hyperoxaluria and cystinuria, in patients attending kidney stone clinics is ∼15%. However, for the majority of individuals, nephrolithiasis has a multifactorial aetiology involving genetic and environmental factors. Nonetheless, the genetic influence on stone formation in these idiopathic stone formers remains considerable and twin studies estimate a heritability of >45% for nephrolithiasis and >50% for hypercalciuria. The contribution of polygenic influences from multiple loci have been investigated by genome-wide association and candidate gene studies, which indicate that a number of genes and molecular pathways contribute to the risk of stone formation. Genetic approaches, studying both monogenic and polygenic factors in nephrolithiasis, have revealed that the following have important roles in the aetiology of kidney stones: transporters and channels; ions, protons and amino acids; the calcium-sensing receptor (a G protein-coupled receptor) signalling pathway; and the metabolic pathways for vitamin D, oxalate, cysteine, purines and uric acid. These advances, which have increased our understanding of the pathogenesis of nephrolithiasis, will hopefully facilitate the future development of targeted therapies for precision medicine approaches in patients with nephrolithiasis.

Abstract
The objective of this study is to find about the association between calcium-sensing receptor (CaSR) genetic variants and susceptibility to nephrolithiasis in the Chinese Han population.This hospital-based case-control study included 319 nephrolithiasis cases and 378 healthy controls subjects. Two SNPs in CaSR were genotyped using the TaqMan assay.We found that subjects carrying the G allele of rs6776158 (AG and GG) had significantly higher risk of nephrolithiasis compared to the AA genotype (P = .015 and .009, respectively).Our results indicate that rs6776158 polymorphism that might elevate the risk of nephrolithiasis in the Chinese population.

Abstract
The human calcium-sensing receptor gene (CASR) has 8 exons, and localizes to chromosome 3q. Exons 1A and 1B encode alternative 5′-untranslated regions (UTRs) that splice to exon 2 encoding the AUG initiation codon. Exons 2–7 encode the CaSR protein of 1078 amino acids. Promoter P1 has TATA and CCAAT boxes upstream of exon 1A, and promoter P2 has Sp1/3 motifs at the start site of exon 1B. Exon 1A transcripts from the P1 promoter are reduced in parathyroid tumors and colon carcinomas. Studies of colon carcinomas and neuroblastomas have emphasized the importance of epigenetic changes—promoter methylation of the GC-rich P2 promoter, histone acetylation—as well as involvement of microRNAs in bringing about CASR gene silencing and reduced CaSR expression. Functional cis-elements in the CASR promoters responsive to 1,25-dihydroxyvitamin D [1,25(OH)2D], proinflammatory cytokines, and the transcription factor glial cells missing-2 (GCM2) have been characterized. Reduced levels of CaSR and reduced responsiveness to active vitamin D in parathyroid neoplasia and colon carcinoma may blunt the “tumor suppressor” activity of the CaSR. The hypocalcemia of critically ill patients with burn injury or sepsis is associated with CASR gene upregulation by TNF-alpha and IL-1beta via kappaB elements, and by IL-6 via Stat1/3 and Sp1/3 elements in the CASR gene promoters, respectively. The CASR is transactivated by GCM2—the expression of which is essential for parathyroid gland development. Hyperactive forms of GCM2 may contribute to later parathyroid hyperactivity or tumorigenesis. The expression of the CaSR—the calciostat—is regulated physiologically and pathophysiologically at the gene level.

Abstract
OBJECTIVE To evaluate correlations between polymorphisms of calcium-sensing receptor (CASR) gene [A986S (rs1081725), R990G (rs1042636) and Q1011E (rs1801726)] and the risk of primary hyperparathyroidism (PHPT) among human population. METHODS Relevant studies were retrieved from online databases using computer-based search strategies, which were then supplemented by manual search strategies. Case-control studies related to our topic were identified based on strict inclusion and exclusion criteria. Statistical analyses were conducted using the Comprehensive Meta-analysis 2.0 (Biostat Inc., Englewood, NJ, USA). RESULTS We retrieved 202 studies from online databases and other sources initially and eventually enrolled six studies into our meta-analysis. These six studies contained a sum of 693 PHPT patients and 1252 healthy controls. Our meta-analysis results showed that single nucleotide polymorphisms (SNPs) of CASR gene A986S (rs1081725) and R990G (rs1042636), but not Q1011E (rs1801726), may increase the risk of PHPT [A986S (rs1081725): allele model: P = 0.013; dominant model: P = 0.044; R990G (rs1042636): allele model: P = 0.023; dominant model: P = 0.026)]. Subgroup analyses based on ethnicity showed that among Asians, A986S (rs1081725) increased the PHPT risk (P = 0.04) under the allele model, but not under the dominant model. Among Caucasians, there was no association between gene frequencies and PHPT under both the allele and dominant model. In Asians, no significant association was observed between R990G (rs1042636) and PHPT risk, but in Caucasians, R990G (rs1042636) significantly increased the incidence of PHPT [R990G (rs1042636): allele model: P = 0.015; dominant model: P = 0.009)]. CONCLUSION Our results indicate that SNPs of CASR gene A986S (rs1081725) and R990G (rs1042636) may increase the risk of PHPT, and the polymorphisms can potentially be used as important biological markers for early diagnosis of PHPT.
