Modulation of ion transport across rat distal colon by cysteine
(2012)The aim of this study was to identify the actions of stimulation of endogenous production of H2S by cysteine, the substrate for the two H2S-producing enzymes, cystathionine-ß-synthase and cystathionine-ß-lyase, on ion ... -
Expression of genes involved in hepatic carnitine synthesis and uptake in dairy cows in the transition period and at different stages of lactation
(2012)Background: In rodents and pigs, it has shown that carnitine synthesis and uptake of carnitine into cells are regulated by peroxisome proliferator-activated receptor alpha (PPARA), a transcription factor which is physiologically ... -
Structural requirements for the procoagulant activity of nucleic acids
(2012)Nucleic acids, especially extracellular RNA, are exposed following tissue- or vessel damage and have previously been shown to activate the intrinsic blood coagulation pathway in vitro and in vivo. Yet, no information on ... -
Gasotransmitters : Novel regulators of epithelial Na+ transport?
(2012)The vectorial transport of Na+ across epithelia is crucial for the maintenance of Na+ and water homeostasis in organs such as the kidneys, lung, or intestine. Dysregulated Na+ transport processes are associated with various ... -
Serum 25-hydroxyvitamin D3, parathyroid hormone and blood pressure in an elderly cohort from Germany : a cross-sectional study
(2012)Background: Although several studies indicate a link between vitamin D status and blood pressure (BP), the results are inconsistent. The purpose of this study is to investigate whether in predominantly non-obese elderly ... -
Aphid gel saliva : Sheath structure, protein composition and secretory dependence on stylet-tip milieu
(2012)In order to separate and analyze saliva types secreted during stylet propagation and feeding, aphids were fed on artificial diets. Gel saliva was deposited as chains of droplets onto Parafilm membranes covering the diets ... -
The coactivator role of histone deacetylase 3 in IL-1-signaling involves deacetylation of p65 NF-kappaB
(2012)Histone deacetylase (HDAC) 3, as a cofactor in co-repressor complexes containing silencing mediator for retinoid or thyroid-hormone receptors (SMRT) and nuclear receptor co-repressor (N-CoR), has been shown to repress gene ... -
Dietary moderately oxidized oil induces expression of fibroblast growth factor 21 in the liver of pigs
(2012)BACKGROUND: Fibroblast growth factor 21 (FGF21), whose expression is induced by peroxisome proliferator-activated receptor alpha (PPARalpha), has been recently identified as a novel metabolic regulator which plays a crucial ... -
Role of the irr protein in the regulation of iron metabolism in Rhodobacter sphaeroides
(2012)In Rhizobia the Irr protein is an important regulator for iron-dependent gene expression. We studied the role of the Irr homolog RSP_3179 in the photosynthetic alpha-proteobacterium Rhodobacter sphaeroides. While Irr had ... -
Molecular networks in FGF signaling : Flotillin-1 and Cbl-associated protein compete for the binding to fibroblast growth factor receptor substrate 2
(2012)Fibroblast growth factor receptor substrate 2 (FRS2α) is a signaling adaptor protein that regulates downstream signaling of many receptor tyrosine kinases. During signal transduction, FRS2 can be both tyrosine and threonine ... -
Regulation of genes involved in carnitine homeostasis by PPARa across different species (rat, mouse, pig, cattle, chicken, and human)
(2012)Recent studies in rodents convincingly demonstrated that PPAR-alpha is a key regulator of genes involved in carnitine homeostasis, which serves as a reasonable explanation for the phenomenon that energy deprivation and ... -
Cre-mediated stress affects sirtuin expression levels, Peroxisome biogenesis and metabolism, antioxidant and proinflammatory signaling pathways
(2012)Cre-mediated excision of loxP sites is widely used in mice to manipulate gene function in a tissue-specific manner. To analyze phenotypic alterations related to Cre-expression, we have used AMH-Cre-transgenic mice as a ... -
Conceptual and visual features contribute to visual memory for natural images
(2012)We examined the role of conceptual and visual similarity in a memory task for natural images. The important novelty of our approach was that visual similarity was determined using an algorithm [1] instead of being judged ... -
The endemic gastropod fauna of Lake Titicaca : correlation between molecular evolution and hydrographic history
(2012)Lake Titicaca, situated in the Altiplano high plateau, is the only ancient lake in South America. This 2- to 3-My-old (where My is million years) water body has had a complex history that included at least five major ... -
Effects of the cryptochrome CryB from Rhodobacter sphaeroides on global gene expression in the dark or blue light or in the presence of singlet oxygen
(2012)Several regulators are controlling the formation of the photosynthetic apparatus in the facultatively photosynthetic bacterium Rhodobacter sphaeroides. Among the proteins affecting photosynthesis gene expression is the ... -
On the contribution of binocular disparity to the long-term memory for natural scenes
(2012)Binocular disparity is a fundamental dimension defining the input we receive from the visual world, along with luminance and chromaticity. In a memory task involving images of natural scenes we investigate whether binocular ... -
The core protein of classical swine fever virus is dispensable for virus propagation in vitro
(2012)Core protein of Flaviviridae is regarded as essential factor for nucleocapsid formation. Yet, core protein is not encoded by all isolates (GBV- A and GBV- C). Pestiviruses are a genus within the family Flaviviridae that ... -
The influence of movement initiation deficits on the quantification of retention in Parkinson s disease
(2012)In patients with an impaired motor system, like Parkinson´s disease (PD), deficits in motor learning are expected and results of various studies seem to confirm these expectations. However, most studies in this regard are ... -
Improving oral hygiene skills by computer-based training : A randomized controlled comparison of the modified bass and the fones techniques
(2012)Background: Gingivitis and other plaque-associated diseases have a high prevalence in western communities even though the majority of adults report daily oral hygiene. This indicates a lack of oral hygiene skills. Currently, ... -
Regulation of the tumor suppressor PML by sequential post-translational modifications
(2012)Post-translational modifications (PTMs) regulate multiple biological functions of the promyelocytic leukemia (PML) protein and also the fission, disassembly, and rebuilding of PML nuclear bodies (PML-NBs) during the cell ...
