  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

  Ingested folate needs to be chemically modified in order to become a one carbon donor for cell metabolism. Firstly, folate turns to dihydrofolic Reversine (DHF), it is then converted into tetrahydrofolate (THF) by the dihydrofolate reductase enzyme (DHFR) and finally converted into N5, N10-methylen

  The present study provides the first evidence that the human uroepithelial BIIB021 synthesis in vitro respond directly, within 48h, to this carcinogen by promoting extensive vacuolation and DAPK expression. By using the TEM, ICC and Western blotting, we found that the arsenite-induced vacuoles were

  Sequence alignment of cfALDH with the human ALDH1 indicates that the cyanobacterial protein contains the same GQCC motif as the human ALDH1 and ALDH2 proteins [24] (Fig. 1d, highlighted in red, and Supplementary Fig. 2). This motif is present in ALDH1/2 orthologues and these residues reside at the b
