Wnt signaling regulates ion channel expression to promote smooth muscle and cartilage formation in developing mouse trachea

Project description:Ion channels play critical roles in the physiology and function of the nervous system and contractile tissue; however, their role in non-contractile tissue and embryonic development has yet to be understood. Tracheobronchomalacia (TBM) and complete tracheal rings (CTR) are disorders affecting the muscle and cartilage of the trachea and bronchi, whose etiology remains poorly understood. We demonstrated that trachealis muscle organization and polarity are disrupted after epithelial ablation of Wls, a cargo receptor critical for the Wnt signaling pathway, in developing trachea. The phenotype resembles the anomalous trachealis muscle observed after deletion of ion channel encoding genes in developing mouse trachea. We sought to investigate whether and how the deletion ofWlsaffects ion channels during tracheal development. We hypothesize that Wnt signaling influences the expression of ion channels to promote trachealis muscle cell assembly and patterning. Deleting Wls in developing trachea causes differential regulation of genes mediating actin binding, cytoskeleton organization, and potassium ion channel activity. Wnt signaling regulated expression of Kcnj13, Kcnd3, Kcnj8, and Abcc9 as demonstrated by in vitro studies and in vivo analysis in Wnt5a and b-catenin deficient tracheas. Pharmacological inhibition of potassium ion channels and Wnt signaling impaired contractility of developing trachealis smooth muscle and formation of cartilaginous mesenchymal condensation. Thus, in mice, epithelial-induced Wnt/b-catenin signaling mediates trachealis muscle and cartilage development via modulation of ion channel expression, promoting trachealis muscle architecture, contractility, and cartilaginous extracellular matrix. In turn, ion channel activity may influence tracheal morphogenesis underlying TBM and CTR.

Transcriptome-based screening of ion channels and transporters in a migratory chondroprogenitor cell line isolated from late-stage osteoarthritic cartilage

Project description:Chondrogenic progenitor cells (CPCs) may be used as an alternative source of cells with potentially superior chondrogenic potential compared to mesenchymal stem cells (MSCs), and could be exploited for future regenerative therapies targeting articular cartilage in degenerative diseases such as osteoarthritis. We studied the profiles of those ion channel and transporter families that may be relevant to chondroprogenitor cell physiology using Affymetrix microarrays.

Mechanosensitive ion channel regulates tissue stiffening to promote glioma aggression

Project description:Tissue stiffening is a physical hallmark of solid tumor. In our study, we found that the mechanosensitive ion channel PIEZO1 can be tumor cells force sensor and transducer that regulate the altered tissue mechanics. We examined the transcriptional changes modulated by depletion of PIEZO1 in two human GBM cell lines. We found that with PIEZO1 KD, the components involved in ECM organization, focal adhesion formation, cytoskeleton, and mitosis, which contribute to tissue stiffness, are down-regulated.

Ion Channel Expression Patterns in Glioblastoma Stem Cells with Functional and Therapeutic Implications for Malignancy

Project description:Ion channels and transporters have increasingly recognized roles in cancer progression through the regulation of cell proliferation, migration, and death. Glioblastoma stem-like cells (GSCs) are a source of tumor formation and recurrence in glioblastoma multiforme, a highly aggressive brain cancer, suggesting that ion channel expression may be perturbed in this population. However, little is known about the expression and functional relevance of ion channels that may contribute to GSC malignancy. Using RNA sequencing, we assessed the enrichment of ion channels in GSC isolates and non-tumor neural cell types. We identified a unique set of GSC-enriched ion channels using differential expression analysis that stratify by molecular subtype and are associated with distinct gene mutation signatures. In support of potential clinical relevance, expression of selected GSC-enriched ion channels evaluated in human glioblastoma databases of The Cancer Genome Atlas and Ivy Glioblastoma Atlas Project correlated with patient survival times. Finally, genetic knockdown or pharmacological inhibition of individual or classes of GSC-enriched ion channels constrained growth of GSCs compared to normal neural stem cells. This first-in-kind global examination characterizes ion channels enriched in GSCs and explores their potential clinical relevance to glioblastoma molecular subtypes, gene mutations, survival outcomes, regional tumor expression, and experimental responses to loss-of-function. Together, the data support the potential biological and therapeutic impact of ion channels on GSC malignancy and provide strong rationale for further examination of their mechanistic and therapeutic importance.

RNAseq quantitative analysis of ion channel mRNA expression in microbead occlusion model

Project description:The purpose of this study was to utilize RNAseq to determine if there are changes in ion channel mRNA expression in the retina of C57BL/6 mice subjected to the Microbead Occlusion Model. Whole retina was isolated from 2 month old mice that received intracameral injections of either saline or 15-um-diameter microbeads. Total RNA was isolated from the retinas and subjected to RNA sequencing using Illumina HiSeq 2500. Fold change in mRNA expression was compared between saline- and microbead-injected samples. We then analyzed these data for changes in expression of potassium channels, such as tandem-pore domain K+ channels, inwardly rectifying K+ channels, and the Na+/K+-ATPase.

Expression data from unactivated vs. activated PBMCs (ion array)

Project description:Long-lasting activation of T cells requires up-regulation of many genes, for example of transcription factors, cytoskeletal proteins and cell surface proteins encluding ion channels. An increase of ion channel density at the cell surface reflects the needs to manage increased Ca2+ influx into the activated T cell. Using oligonucleotide-based arrays we have surveyed changes in ion channel mRNA expression that occur upon T cell activation.

CALHM6 is an immunological synapse ion channel required for macrophage-natural killer cell communication upon bacterial infection

Project description:Membrane ion channels of the calcium homeostasis modulator (CALHM) family promote cell-cell crosstalk at synapses via ATP release, where ATP acts as a neurotransmitter. CALHM6, the only CALHM highly expressed in immune cells, has been linked to induction of natural killer (NK) cell anti-tumour activity. Its mechanism of action and broader functions in the immune system are, however, unclear. Here we generated Calhm6-/- mice and report that CALHM6 is important for regulating the early innate control of Listeria monocytogenes infection in vivo. We find that CALHM6 is upregulated in macrophages by pathogen-derived signals, and that it relocates from intracellular compartment to the macrophage-NK cell synapse, facilitating ATP release and controlling the kinetics of NK cell activation. Anti-inflammatory cytokines terminate CALHM6 expression. CALHM6 forms an ion channel when expressed in the plasma membrane of Xenopus oocytes, where channel opening is controlled by a conserved acidic residue, E119, but CALHM6 is localized to intracellular compartments in mammalian cells. Our results contribute to understanding of neurotransmitter-like signal exchange between immune cells that fine-tunes the timing of innate immune responses.
