Inspite of several stimulating developments in gene therapy, the formulation of a targeted gene delivery "vector" is still far from ideal. We have demonstrated the potential of reconstituted Sendai viral envelopes containing only the fusion glycoprotein (F-virosomes) in targeted delivery of reporter genes to liver cells of BALB/c mouse in vivo. The membrane fusion-mediated high efficiency of ge...
The chloramphenicol acetyltransferase (cat) gene from Streptomyces acrimycini encodes a leaderless mRNA. Expression of the cat coding sequence as a leaderless mRNA from a modified lac promoter resulted in chloramphenicol resistance in Escherichia coli. Transcript mapping with nuclease S1 confirmed that the 5' end of the cat message initiated at the A of the AUG translational start codon. Site-d...
the use of organophosphorus hydrolase (oph) enzyme to degrade chemical warfare agents is one of the most frequently used decontamination methods. oph is a ~36 kda homodimeric metalloprotein that is found in the membrane of flavobacterium sp. strain atcc 27551 and brevundimonas diminuta mg and is capable of hydrolyzing a wide range of oxon and thion , such as paraoxon and parathion. oph gene ( o...
Gene silencing using RNAi (RNA interference), has recently been used as a successful laboratory technique in determining the function and control of gene expression and provides a wide range of applications in molecular biology and gene therapy. RNAi is a method of suppressing gene expression. In this direction, a single-stranded RNA molecule of about 21–23 nucleotides, called siRNA (small inte...
Using synthetic oligonucleotide probes, we have isolated chicken cDNA clones for the intermediate filament protein desmin. We show that the gene for this protein probably exists as a single copy in the haploid chicken genome and is transcribed into one mature mRNA species of approximately equal to 2.4 kilobases. Expression of this mRNA is tissue-specific, as it is present in high abundance in s...
background: gamma -aminobutyric acid (gaba), a non-protein amino acid acts as an inhibitory neurotransmitter in the central nervous system of mammalians. the glutamate decarboxylase (gad) is responsible for the conversion of l-glutamate to gaba. the human brain has two isoforms of this enzyme, gad65 and gad67 that differ in molecular weight, amino acid sequence, antigenicity, cellular location ...
Background: Development of cloned bovine embryos. Materials and Methods: Oocytes collection,oocyte denudation, oocyte enucleation, nuclear transfer, electrofusion, reconstructed embryo activation, culture of reconstructed and IVF embryo,and treatment with SAH post fusion interval Treatment of reconstructed embryos with TSA for 12 hours after activation, preparation of somatic donor cells, donor...
OBJECTIVE Polymorphisms in the human TCF7L2 gene are associated with reduced insulin secretion and an increased risk of type 2 diabetes. However, the mechanisms by which TCF7L2 affect insulin secretion are still unclear. We define the effects of TCF7L2 expression level on mature beta-cell function and suggest a potential mechanism for its actions. RESEARCH DESIGN AND METHODS TCF7L2 expression...
We have identified a t(8;9)(p21-23;p23-24) in seven male patients (mean age 50, range 32-74) with diverse hematologic malignancies and clinical outcomes: atypical chronic myeloid leukemia/chronic eosinophilic leukemia (n = 5), secondary acute myeloid leukemia (n = 1), and pre-B-cell acute lymphoblastic leukemia (n = 1). Initial fluorescence in situ hybridization studies of one patient indicated...
Control of gene expression by the phosphatidylinositol (PI) 3-kinase/Akt pathway plays an important role in mammalian cell proliferation and survival, and numerous transcription factors and genes regulated by PI 3-kinase signaling have been identified. Because steady-state levels of mRNA are regulated by degradation as well as transcription, we have investigated the importance of mRNA degradati...
