Trpm7-Mediated Ca2+ Signals Confer Fibrogenesis In Human Atrial Fibrillation, Jianyang Du, Jia Xie, Zheng Zhang, Hiroto Tsujikawa, Daniel Fusco, David Silverman, Bruce Liang, Lixia Yue

UCHC Articles - Research

Rationale—Cardiac fibrosis contributes to pathogenesis of atrial fibrillation (AF), which is the most sustained arrhythmia and a major cause of morbidity and mortality. Although it has been suggested that Ca2+ signals are involved in fibrosis promotion, the molecular basis of Ca2+ signaling mechanisms and how Ca2+ signals contribute to fibrogenesis remain unknown.
Objective—To determine the molecular mechanisms of Ca2+-permeable channel(s) in human atrial fibroblasts, and to investigate how Ca2+ signals contribute to fibrogenesis in human AF.
Methods and Results—We demonstrate that the transient receptor potential melastatin related 7 (TRPM7) is the molecular basis of the ...

The Yellowstone caldera contains the most numerous and diverse geothermal systems on Earth, yielding an extensive array of unique high-temperature environments that host a variety of deeply-rooted and understudied Archaea, Bacteria and Eukarya. The combination of extreme temperature and chemical conditions encountered in geothermal environments often results in considerably less microbial diversity than other terrestrial habitats and offers a tremendous opportunity for studying the structure and function of indigenous microbial communities and for establishing linkages between putative metabolisms and element cycling. Metagenome sequence (14-15,000 Sanger reads per site) was obtained for five hightemperature (>65°C) chemotrophic microbial communities sampled ...

Efficient Activation Of Reconstructed Rat Embryos By Cyclin-Dependent Kinase Inhibitors, Robin L. Webb, Kirk A. Findlay, Michael A. Green, Tina L. Beckett, M. Paul Murphy

Molecular and Cellular Biochemistry Faculty Publications

Background

Over the last decade a number of species, from farm animals to rodents, have been cloned using somatic cell nuclear transfer technology (SCNT). This technique has the potential to revolutionize the way that genetically modified animals are made. In its current state, the process of SCNT is very inefficient (<5% success rate), with several technical and biological hurdles hindering development. Yet, SCNT provides investigators with powerful advantages over other approaches, such as allowing for prescreening for the desired level of transgene expression and eliminating the excess production of undesirable wild-type animals. The rat plays a significant role in biomedical research, but SCNT has been problematic for this species. In this study, we address one aspect of the problem by evaluating methods of activation in artificially constructed rat embryos.

Principal Findings

We demonstrate that treatment with a calcium ionophore (ionomycin) combined with a variety of cyclin-dependent kinase inhibitors is an effective way to activate rat embryos. This is in contrast to methods developed for the mouse embryo, which tolerates much less specific chemical treatments. Methods developed to activate mouse ...

Optimizing Vaccine Allocation At Different Points In Time During An Epidemic, Laura Matrajt, Ira M. Longini Jr. 2010 University of Washington

Optimizing Vaccine Allocation At Different Points In Time During An Epidemic, Laura Matrajt, Ira M. Longini Jr.

UW Biostatistics Working Paper Series

For current pandemic influenza H1N1, vaccine production started in the early summer, and vaccination started in the fall. In most countries, by the time vaccination started, the second wave of H1N1 was already under way. With limited supplies of vaccine, it might be a good strategy to vaccinate the high-transmission groups earlier in the epidemic, but it might be a better use of resources to protect instead the high-risk groups later on. We develop a deterministic epidemic model with two age-groups (children and adults) and further subdivide each age group in low and high risk. We compare optimal vaccination strategies ...

CFSPH fichas de las enfermedades

El virus de la coriomeningitis linfocítica (VCML) es un patógeno, normalmente llevado por los roedores, que puede causar meningitis aséptica y otros trastornos en humanos. Si bien la mayoría de las personas presentan una enfermedad relativamente leve y las infecciones mortales son poco comunes, las embarazadas pueden dar a luz recién nacidos infectados congénitamente, con anormalidades graves en el cerebro y los ojos. En pocos casos, este virus se ha transmitido en órganos transplantados, causando, generalmente, una enfermedad mortal. Las infecciones del VCML en roedores son frecuentemente asintomáticas; sin embargo, en algunos animales, se pueden observar signos clínicos agudos o ...

BACKGROUND: Neurotrophic factors, such as glial cell line-derived neurotrophic factor (GDNF), have shown great promise for protection and restoration of damaged or dying dopamine neurons in animal models and in some Parkinson's disease (PD) clinical trials. However, the delivery of neurotrophic factors to the brain is difficult due to their large size and poor bio-distribution. In addition, developing more efficacious trophic factors is hampered by the difficulty of synthesis and structural modification. Small molecules with neurotrophic actions that are easy to synthesize and modify to improve bioavailability are needed.

METHODS AND FINDINGS: Here we present the neurobiological actions of ...

Research has demonstrated that vulnerable populations including disadvantaged populations of color live in areas that may place them at higher risk of exposure to social and environmental hazards. Due to climate change, these populations may experience worse health outcomes and environmental health disparities. The purpose of this project was to explore the use of Geographic Information Systems (GIS) to assess areas that may be vulnerable to climate change across the United States. We employed ArcGIS 9.3 to create vulnerability scores for areas across the country that may be that may be impacted by climate change at the county level ...

Metabolic Autocrine Regulation Of Neurons Involves Cooperation Among Pannexin Hemichannels, Adenosine Receptors And Katp Channels, Masahito Kawamura Jr., David N. Ruskin, Susan A. Masino

Faculty Scholarship

Metabolic perturbations that decrease or limit blood glucose—such as fasting or adhering to a ketogenic diet—reduce epileptic seizures significantly. To date, the critical links between altered metabolism and decreased neuronal activity remain unknown. More generally, metabolic changes accompany numerous CNS disorders, and the purines ATP and its core molecule adenosine are poised to translate cell energy into altered neuronal activity. Here we show that nonpathological changes in metabolism induce a purinergic autoregulation of hippocampal CA3 pyramidal neuron excitability. During conditions of sufficient intracellular ATP, reducing extracellular glucose induces pannexin-1 hemichannel-mediated ATP release directly from CA3 neurons. This extracellular ...
