    In rat vascular smooth muscle cells (RVSMC), 3-h Na,K-ATPase inhibition by ouabain or in K-free medium resulted in the inversion of the [Na]/[K]ratio and elevation up to 7-fold the content of Egr1, Atf3, Nr4a1 and Ptgs2 mRNAs. Ouabain increased the rate of 45Cainflux by 2-fold that was abolished by L-type voltage-gated Cachannel blocker nicardipine, but it was resistant to Na/Caexchanger inhibitor KB-R7943. To study the role of Ca-mediated signaling in the expression of Na/K-sensitive genes we used intracellular Cachelator BAPTA and incubated RVSMC in Ca-free medium. Read More

    Fusion pore in exocytosis: More than an exit gate? A β-cell perspective.

    Secretory vesicle exocytosis is a fundamental biological event and the process by which hormones (like insulin) are released into the blood. Considerable progress has been made in understanding this precisely orchestrated sequence of events from secretory vesicle docked at the cell membrane, hemifusion, to the opening of a membrane fusion pore. The exact biophysical and physiological regulation of these events implies a close interaction between membrane proteins and lipids in a confined space and constrained geometry to ensure appropriate delivery of cargo.

    Regulated exocytosis can be split into a sequence of steps ending with the formation and the dilation of a fusion pore, a neck-like connection between the vesicle and the plasma membrane. Each of these steps is precisely controlled to achieve the optimal spatial and temporal profile of the release of signalling molecules. At the level of the fusion pore, tuning of the exocytosis can be achieved by preventing its formation, by stabilizing the unproductive narrow fusion pore, by altering the speed of fusion pore expansion and by completely closing the fusion pore.

    Calcium (Ca) signaling plays a critical role in regulating plethora of cellular functions including cell survival, proliferation and migration. The perturbations in cellular Cahomeostasis can lead to cell death either by activating autophagic pathways or through induction of apoptosis. Endoplasmic reticulum (ER) is the major storehouse of Cawithin cells and a number of physiological agonists mediate ER Carelease by activating IPreceptors (IPR). Read More

    The plasma membrane Ca-ATPase (PMCA) is a ubiquitously expressed, ATP-driven Capump that is critical for maintaining low resting cytosolic Ca([Ca]) in all eukaryotic cells. Since cytotoxic Caoverload has such a central role in cell death, the PMCA represents an essential "linchpin" for the delicate balance between cell survival and cell death. In general, impaired PMCA activity and reduced PMCA expression leads to cytotoxic Caoverload and Cadependent cell death, both apoptosis and necrosis, whereas maintenance of PMCA activity or PMCA overexpression is generally accepted as being cytoprotective.

    The folding of secretory proteins is a well-understood mechanism, based on decades of research on endoplasmic reticulum (ER) chaperones. These chaperones interact with newly imported polypeptides close to the ER translocon. Classic examples for these proteins include the immunoglobulin binding protein (BiP/GRP78), and the lectins calnexin and calreticulin. Read More

    Polycystin and calcium signaling in cell death and survival.

    Mutations in polycystin-1 (PC1) and polycystin-2 (PC2) result in a commonly occurring genetic disorder, called Autosomal Dominant Polycystic Kidney Disease (ADPKD), that is characterized by the formation and development of kidney cysts. Epithelial cells with loss-of-function of PC1 or PC2 show higher rates of proliferation and apoptosis and reduced autophagy. PC1 is a large multifunctional transmembrane protein that serves as a sensor that is usually found in complex with PC2, a calcium (Ca)-permeable cation channel. Read More

    Casignaling, apoptosis and autophagy in the developing cochlea: Milestones to hearing acquisition.

    In mammals, the sense of hearing arises through a complex sequence of morphogenetic events that drive the sculpting of the auditory sensory epithelium into its terminally functional three-dimensional shape. While the majority of the underlying mechanisms remain unknown, it has become increasingly clear that Casignaling is at center stage and plays numerous fundamental roles both in the sensory hair cells and in the matrix of non-sensory, epithelial and supporting cells, which embed them and are tightly interconnected by a dense network of gap junctions formed by connexin 26 (Cx26) and connexin 30 (Cx30) protein subunits. In this review, we discuss the intricate interplay between Casignaling, connexin expression and function, apoptosis and autophagy in the crucial steps that lead to hearing acquisition. Read More

    Transient receptor potential (TRP) ion channels regulate fundamental biological processes throughout the body. TRP channel dysfunction has been causally linked to a number of disease states and thus establishes these channels as promising therapeutic targets. In order to dissect the physiological role of individual TRP channels in specific tissues, a detailed understanding of the expression pattern of the different TRP channels throughout the organism is essential.

    In spite of significant scientific progress in recent years, acute pancreatitis (AP) is still a dangerous and in up to 5% of cases deadly disease with no specific cure. It is self-resolved in the majority of cases, but could result in chronic pancreatitis (CP) and increased risk of pancreatic cancer (PC). One of the early events in AP is premature activation of digestive pro-enzymes, including trypsinogen, inside pancreatic acinar cells (PACs) due to an excessive rise in the cytosolic Caconcentration, which is the result of Carelease from internal stores followed by Caentry through the store operated Cachannels in the plasma membrane.

    The immune system protects our body against foreign pathogens. However, if it overshoots or turns against itself, pro-inflammatory diseases, such as rheumatoid arthritis, inflammatory bowel disease, or diabetes develop. Ions, the most basic signaling molecules, shape intracellular signaling cascades resulting in immune cell activation and subsequent immune responses. Read More

    The role of Cain cell death caused by oxidative glutamate toxicity and ferroptosis.
    Cell Calcium 2018 Mar 12;70:47-55. Epub 2017 May 12.
    University Medical Center and Focus Program Translational Neuroscience (FTN) of the Johannes Gutenberg University Mainz, Department of Neurology, Mainz, Germany. Electronic address:
    Caions play a fundamental role in cell death mediated by oxidative glutamate toxicity or oxytosis, a form of programmed cell death similar and possibly identical to other forms of cell death like ferroptosis. Cainflux from the extracellular space occurs late in a cascade characterized by depletion of the intracellular antioxidant glutathione, increases in cytosolic reactive oxygen species and mitochondrial dysfunction. Here, we aim to compare oxidative glutamate toxicity with ferroptosis, address the signaling pathways that culminate in Cainflux and cell death and discuss the proteins that mediate this. Read More
