Cloning, characterization, and functional studies of a nonintegrin platelet receptor for type I collagen.

Cloning, characterization, and functional studies of a 47-kDa platelet receptor for type III collagen.

A 1.2-kb cDNA fragment encoding a platelet 47-kDa protein has been isolated from a human bone marrow cDNA library by using a degenerate oligonucleotide of the sequenced amino terminus of the purified platelet protein with a poly(dT)(12).(dG) by polymerase chain reaction. A computer search revealed that the cDNA represents the coding sequence of a protein with a fragmentary homology to several p...

Rapid tyrosine phosphorylation and activation of Bruton's tyrosine/Tec kinases in platelets induced by collagen binding or CD32 cross-linking.

Stimulation of the platelet nonintegrin collagen receptor, glycoprotein VI, evokes a signaling response similar to that induced by antigen receptor activation in B and T lymphocytes. A key transducer of the lymphocyte signaling pathways is the Bruton's tyrosine kinase (Btk)/Tec kinase family, which connects receptors to the elevation of intracellular-free calcium levels. An important signaling ...

Up-Regulation of Integrinsn α2β1 and α3β1 Expression in Human Foreskin Fibroblast Cells after In-Vitro Infection with Herpes Simplex Virus Type 1

The interaction of Herpes Simplex Virus type 1 (HSV-1) with human fetal foreskin fibroblast (HFFF) cell was studied using a recent isolate of HSV-1 which was propagated in Hep-2 cells. HFFF cells were challenged with HSV-1 with a multiplicity of infection (MOI) of 1 virus/cell for 24 hours. Flow cytometric analysis demonstrated that HSV-1 challenged HFFF cells expressed increased levels of α2β1...

P-84: Characterization of Androgen Receptor Structure and Nucleocytoplasmic Shuttling of the Rice Field Eel

Background: Androgen receptor (AR) plays a critical role in prostate cancer and male sexual differentiation.Mechanisms by which AR acts and regulations of AR nucleocytoplasmic shuttling are not understood well. Materials and Methods: Degenerate PCR and RACE Cloning of AR Gene; Phylogenetic Analysis and Molecular Modeling;Real-time Fluorescent Quantitative RT-PCR; Northern Blot Hybridization;In ...
