The sequence for cDNA encoding the NMDA receptor subunit 1 (aptNR1) of the weakly electric fish Apteronotus leptorhynchus has been determined. The deduced amino acid sequence is approximately 88% identical to other vertebrate NR1 proteins, with sequence homology extending to the alternatively spliced cassettes N1 and C1. The fish and mammalian N1 and C1 splice cassettes are identical at 20 of 2...
Botulinum neurotoxin (BoNT) binds to and internalizes its light chain into presynaptic compartments with exquisite specificity. While the native toxin is extremely lethal, bioengineering of BoNT has the potential to eliminate toxicity without disrupting neuron-specific targeting, thereby creating a molecular vehicle capable of delivering therapeutic cargo into the neuronal cytosol. Building upo...
Published data on any association between the CYP2E1 RsaI/PstI (c1/c2) polymorphism and liver cancer risk among east Asians are inconclusive. The aim of this Human Genome Epidemiology (HuGE) review and meta- analysis was to derive a more precise estimation of the relationship. A literature search of Pubmed, Embase, Web of science and CBM databases from inception through July 2012 was conducted....
A 56 residue fragment derived from a Waldenströme IgM protein and consisting of 24 residues of the amino-terminal portion of the Cmu4 domain disulfide bonded to 32 residues of the carboxy-terminal region of the loop has been shown to fix active C1 (C1) in a C1-fixation assay. Cleavage of the disulfide bond within the CH4 fragment resulted in a marked decrease of C1-fixing ability, although the ...
The purpose of this study was to establish an in vitro model for tumor progression in colorectal carcinogenesis, by transforming the premalignant human colonic PC/AA adenoma cell line to the malignant phenotype. A rare clonogenic variant AA/C1 [colony-forming efficiency (CFE) on plastic of 1.05%] was isolated from the diploid PC/AA adenoma cell line (C. Paraskeva, S. Finerty, and S. Powell, Int...
Epinephrine-containing neurons of the rostral ventrolateral medulla (RVL) (the C1 group of Hökfelt) in the rat are primarily unilaterally innervated by neurons in the nucleus tractus solitarius (NTS) and in turn project to autonomic spinal neurons. In this study, we investigated whether the C1 area of the RVL mediates the vasodepressor responses (VDR) induced by either electrical stimulation of...
Protease nexin I is a proteinase inhibitor that is secreted by human fibroblasts and forms stable complexes with certain serine proteinases; the complexes then bind to the fibroblasts and are rapidly internalized and degraded. In this report, we show that this inhibitor, which is present in very low concentrations in plasma, has functional and structural similarities to C1 inhibitor, an abundan...
