- P2X7 is an adenosine 5'-triphosphate (ATP)-gated ion channel. CD39 (ectonucleotidase triphosphate diphosphohydrolase-1) hydrolyses ATP to reduce its extracellular concentration to limit P2X7 activation. Both P2X7 and CD39 are present on leukocytes. Ficoll-Paque density gradient centrifugation is widely used to isolate human peripheral blood mononuclear cells (PBMCs), yet the extent to which other density gradient centrifugation methods influence the expression of cell surface molecules remains unclear. Using mass cytometry, this study compared the proportions of mononuclear leukocyte subsets and the relative amount of cell surface P2X7 and CD39 detected on these cells in paired, bar-coded cryopreserved human PBMC samples isolated by Ficoll-Paque or SepMate Tube density gradient centrifugation. Both techniques yielded similar proportions of mononuclear leukocyte subsets. P2X7 and CD39 were detected across all cell subsets, with the relative amount of P2X7 or CD39 comparable between separation methods. Relatively minor but statistically significant differences were observed for some populations. P2X7 expression was higher on CD3, CD4, and conventional CD4 T cells, and naïve B cells, and lower on myeloid dendritic cells, while CD39 expression was lower on regulatory T cells in SepMate Tube samples compared to Ficoll-Paque samples. Overall, Ficoll-Paque and SepMate Tube density gradient centrifugation yield comparable results within PBMC samples, supporting the use of either method in studies examining immune phenotypes including the purinergic molecules P2X7 and CD39. - Source: PubMed

Elhage AmalGunasegaran BavaniSmith NatalieTurner Ross JWatson DebbieMcGuire Helen MSluyter Ronald - Although some molecular genes in the pathological mechanism of hepatocellular carcinoma (HCC) have been explored, determining the molecular targets and functional roles in the progress of HCC has important clinical significance for the prevention and treatment of HCC. The ATP-gated P2X7 receptor (P2RX7) is an ion channel-type receptor that is expressed in most tumors and regulates tumor progression. However, the relationship between P2RX7 expression and HCC patients and its functional role in HCC migration and invasion need to be further investigated and determined. - Source: PubMed

Min Wen-LanZhang XinZhang Qi - The human P2X7 purinergic receptor is an ATP-gated ion channel expressed across a wide range of cell types, including immune, epithelial, glial, and various cancer cells. Despite its broad expression and diverse functions, little is known about the transcriptional regulation of the P2RX7 gene. In this study, the transcription initiation site of the P2RX7 gene was mapped 149/148 nucleotides upstream of the ATG start codon by using a sequencing-based primer extension method. To characterise the promoter region of the P2RX7 gene, eight DNA fragments were cloned into a dual-colour luciferase reporter vector system. The promoter activity of each fragment was assessed in transfected HEK-293 and COS-7 cells. Predicted promoter binding sequences were identified, and fluorescence-based super-electrophoretic mobility shift assay confirmed that the transcription factors YY1 and C/EBPβ directly bind to the P2RX7 promoter region. - Source: PubMed

Liu LuyaoKagawa YoshiteruMasters Colin LStylli Stanley SMantamadiotis TheoGu Ben J - The P2RX7 gene has been linked to various neuropsychiatric disorders. In particular, the SNP rs2230912, which results in a glutamine-to-arginine substitution at position 460, has repeatedly been associated with mood disorders. Although this SNP per se does not affect receptor function, it tags a gain-of-function haplotype that has been shown to significantly enhance receptor activity. BAC-transgenic P2X7-reporter mice have proven to be valuable tools for monitoring P2X7 expression. Here, we exploited their capacity to simultaneously overexpress the receptor, thereby serving as gain-of-function models to assess the behavioral consequences of elevated P2X7 levels. We used the two currently available transgenic P2X7 reporter lines (sEGFP and P2X7-EGFP), which differ in their expression pattern, degree of overexpression, and co-expression of the neighbouring P2rx4 gene. Male sEGFP and P2X7-EGFP mice showed no alterations in general activity or in measures of anxiety-related or stress-coping behavior compared to their wild-type littermates. Only male P2X7-EGFP mice exhibited slightly delayed locomotor habituation to a novel environment. To what extent higher expression levels reflect enhanced receptor activity, as conveyed by the disease-associated gain-of-function haplotype, requires further investigation. Overall, these results indicate that P2X7 overexpression-whether at endogenous or ectopic sites, or in conjunction with P2X4-is not sufficient to substantially alter behavior of individually housed male mice under baseline conditions. - Source: PubMed

Urbina-Treviño LidiaTang Haovon Mücke-Heim Iven-AlexEngel TobiasNicke AnnetteDeussing Jan M - Rett syndrome is a neurodevelopmental disorder caused by mutations in MECP2 and is frequently associated with scoliosis; however, the molecular mechanisms linking MeCP2 dysfunction to this phenotype remain poorly understood. In this study, we identify LBX1, a gene implicated in adolescent idiopathic scoliosis, as a downstream target of MeCP2 and investigate its regulatory role in neuronal gene expression. Chromatin immunoprecipitation (ChIP) analysis demonstrated that MeCP2 binds to the promoter region of LBX1, which contains a CT-rich and highly methylated sequence, providing a favorable context for MeCP2 binding. Consistently, CRISPR/Cas9-mediated disruption of MECP2 in A172 cells resulted in a marked reduction of LBX1 expression, whereas expression of the antisense transcript LBX1-AS remained unchanged, indicating gene-specific regulation. These findings support a role for MeCP2 as a transcriptional activator of LBX1 in this context. Given the established role of LBX1 in specifying GABAergic and glutamatergic neuronal identities, we performed targeted gene expression profiling using a GABA and glutamate-related PCR array. Several neuronal genes were differentially expressed in MeCP2-deficient cells, and GABRB1 and P2RX7 were identified as LBX1-dependent downstream targets, as their expression levels were restored by ectopic expression of LBX1. Together, these findings reveal a previously unrecognized MeCP2-LBX1 regulatory axis and suggest that its disruption may contribute to altered neuronal signaling. This pathway provides a potential molecular link between MeCP2 dysfunction and scoliosis in Rett syndrome. - Source: PubMed
