DENN domains are found in a variety of signaling proteins but their exact function remains undefined. Some of the DENN-containing proteins, such as rat Rab3GEP (Rab3 GDP/GTP exchange protein) or mouse Rab6IP1 (Rab6 interacting protein 1) interact with GTPases of the Rab family. Others, such as human MADD (MAP (Mitogen-activated protein) kinase activating(More)
Histamine H3 receptor inverse agonists are known to enhance the activity of histaminergic neurons in brain and thereby promote vigilance and cognition. 1-{3-[3-(4-Chlorophenyl)propoxy]propyl}piperidine, hydrochloride (BF2.649) is a novel, potent, and selective nonimidazole inverse agonist at the recombinant human H3 receptor. On the stimulation of guanosine(More)
OBJECTIVE The Shal (or Kv4) gene family has been proposed to be responsible for primary subunits of the transient outward potassium current (Ito). More precisely, Kv4.2 and Kv4.3 have been suggested to be the most likely molecular correlates for Ito in rat cells. The purpose of the present study was to compare the properties of the rat Kv4.3 gene product(More)
The human Cx40 gene (NT_004434.5) was sorted out from the GenBank database and as a result of a BLAST homology search, two ESTs (BE784549 from a human lung database, and BE732411 from a human placenta database) overlapping with the coding exon 2 sequence and upstream regions of the gene were identified. These ESTs correspond to two transcripts 1A and 1B,(More)
Higher order DNA fragmentation may be an essential signal in apoptosis. We found that etoposide (VP-16) induced apoptosis in human DU-145 prostatic carcinoma cells in a time- and concentration-dependent manner. Chromatin condensation was morphologically evident only when cells detached from the monolayer; untreated or VP-16-treated attached cells retained a(More)
A series of compounds containing privileged scaffolds of the known histamine H(1) receptor antagonists cetirizine, mianserin, ketotifen, loratadine, and bamipine were synthesized for further optimization as ligands for the related biogenic amine binding dopamine D(3) receptor. A pharmacological screening was carried out at dopamine D(2) and D(3) receptors.(More)
The stroma reaction plays a central role in tumor growth, invasion and metastasis. Tumor growth is dependent on angiogenesis and requires the vascular supply provided by new capillary blood vessels of the stroma. The expression of the gene encoding the transcription factor c-ets1 is localized within fibroblasts and endothelial cells of the stromal(More)
The endothelium represents a potentially critical target for gene therapy because of its anatomical location and its importance in the viability in both normal and malignant tissues. Protecting the endothelium of normal tissues, such as the lungs, from the toxic effects of current antineoplastic agents and the destruction of the tumor vasculature are(More)
AIMS This study aimed at characterizing expression and the functional role of the Gjb6 gene, encoding for connexin 30 (Cx30) protein, in the adult mouse heart. METHODS AND RESULTS The expression of the Gjb6 gene in the mouse heart was investigated by RT-PCR and sequencing of amplified cDNA fragments. The sites of Gjb6 expression were identified in the(More)
Sphingosine 1-phosphate (S1P), which derives from the metabolism of sphingomyelin, is mainly synthesized, stored, and released from platelets after activation by physiological and pathophysiological events. S1P acts in cardiovascular tissues through cell surface G-protein-coupled receptors of the endothelial differentiation gene (EDG) family, i.e., EDG1,(More)
