  Extracellular uridine can be transported across the cell membrane to enter the nucleotide salvage pathway. A colon cancer cell line supplemented with uridine was capable of growing normally in the presence of 1 μM brequinar (Peters et al., 1992). The supplemented uridine may be transported into the

  Introduction Sphingolipids are ubiquitous membrane components of all eukaryotic cells belonging to a group of complex lipids. The basic structure of sphingolipids is composed of a sphingoid long chain base (LCB) linked to a fatty Ro3306 via an amide bond to form a ceramide [1]. In animals, sphin

  The role of Epac in the regulation of intracellular Ca homeostasis and contractility is still matter of debate. In rat adult cardiomyocytes, acute Epac stimulation decreased the amplitude of Ca transients [6], [9], [10] with either no changes [6] or increments [9] in cell shortening, suggesting an e

  We next turned our attention to the 6-position of the indole (). It was found that the chlorine atom present in was extremely important. The des-chloro analogue showed nearly 30-fold less affinity for the EP receptor in the binding assay and was nearly 30-fold lower in activity in the functional a

  Glycolysis is important to maintain the vital functions of T. gondi. Extracellular T. gondii shift its Iberiotoxin metabolism towards glycolysis, based on the observation that a relocation of glycolytic enzymes from the cytosol to the pellicle occurs at the time when tachyzoites egress from host ce

  Conflict of interest Introduction Endothelin receptors are members of the superfamily of G-protein-coupled receptors (GPCRs) and central regulators of vascular tension and other physiological functions in higher eukaryotes [1]. The human endothelin system comprises the highly homologous endoth

  The significance of the difference in the DDR2 binding specificity towards fibrillar and non-fibrillar collagens is not understood, but may imply differences in biological responses when chondrocytes bind to different collagens in the growth plate. Investigations by Labrador et al. (2001) have shown

  Oxidation of N-hydroxyguanidine 1 by DbH was studied by HPLC and some oxidation products for 1 could be characterized. The compounds generally observed with iron-containing systems are 4-methoxyphenylurea 11 and 4-methoxyphenylcyanamide 12 (Fig. 2). Oxidation of N-(4-chlorophenyl)-N′-hydroxyguanidin

  Another mechanism underlying on the toxicity of dopaminergic neurons might be related to dopamine-dependent initial oxidative stress [60]. Dopamine ace inhibitors mediated by monoamine oxidase (MAO) can produce hydrogen peroxide as a by-product, and excess dopamine can undergo auto-oxidation to qui
