The success of Cre-mediated conditional gene targeting depends on the specificity of Cre recombinase expression in Cre-transgenic mouse lines. As a tool to evaluate the specificity of Cre expression, we developed a reporter transgenic mouse strain that expresses enhanced green fluorescent protein (EGFP) upon Cre-mediated recombination. We demonstrate that(More)
We have determined the complete nucleotide sequence of chloroplast DNA from a liverwort, Marchantia polymorpha, using a clone bank of chloroplast DNA fragments. The circular genome consists of 121,024 base-pairs and includes two large inverted repeats (IRA and IRB, each 10,058 base-pairs), a large single-copy region (LSC, 81,095 base-pairs), and a small(More)
Brain-derived neurotrophic factor (BDNF), a member of the neurotrophins, promotes differentiation and survival of various types of neurons in the central nervous system. BDNF binds to and activates the tyrosine kinase receptor, TrkB, initiating intracellular signaling and exerting its effects. Phosphatidylinositol 3-kinase (PI3-K), which has been implicated(More)
BIT/SHPS-1/SIRPalpha/P84 is a unique molecule with a high degree of homology with immune antigen recognition molecules (immunoglobulin, T-cell receptor and MHC), and is highly expressed in the brain. The extracellular region contains three immunoglobulin-like domains (V-type, C1-type and C1-type), and the intracellular region contains two signalling motifs(More)
gamma delta T cells respond to a variety of microbial pathogens and transformed cells. Their limited receptor repertoire and activation by mycobacterial antigens resistant to proteases suggest that they may recognize nonpeptide antigens. We have tested a variety of nonpeptide molecules for stimulation of human gamma delta T cells. Synthetic alkyl(More)
delta-Aminolevulinic acid dehydratase (porphobilinogen synthase; 5-aminolevulinate hydro-lyase, EC 4.2.1.24) was purified from rat and rabbit erythrocytes to a homogeneous state. Specific activities were 26.0 and 26.6 units/mg protein for the rat and rabbit enzymes, respectively, and their estimated molecular weight was 280000, each consisting of 8 subunits(More)
To detect the diagnostic criteria for mitral prosthetic valve dysfunction, Doppler echocardiography was used to assess valve function following mitral valve replacement in 100 patients [50 with St. Jude Medical (SJM) valves, 50 with Björk-Shiley (B-S) valves]. Mitral valve area (MVA) was calculated by dividing a constant of 220 by pressure half time (PHT)(More)
Monodehydroascorbate (MDA) reductase catalyzes the reduction of MDA, the only organic radical substrate for the enzyme reported so far. Here, we show that cucumber MDA reductase is also capable of reducing phenoxyl radicals which are generated by horseradish peroxidase (HRP) with H2O2. The addition of MDA reductase plus NADH suppressed the HRP/H2O2(More)
BIT (a brain immunoglobulin-like molecule with tyrosine-based activation motifs) is a brain-specific membrane protein which has two cytoplasmic TAMs (tyrosine-based activation motifs). Using the Far Western blotting technique, we detected association of a 70-kDa protein with the tyrosine-phosphorylated TAMs of BIT. A mouse brain cDNA library in lambdagt11(More)
