Development of Molecular Genetic Interventions for HIV Infection
(John Wiley & Sons, 1997-02)
This unit includes a set of protocols for the ex vivo transfer of genes into CD4+ T cells, to be used in the initial evaluation of genes protecting against HIV infection in gene therapy protocols. The describes isolating ...
The gene for a novel epidermal antigen maps near the neurofibromatosis 1 gene
(Elsevier, 1992-10)
Recently the M17S1 gene, encoding an epidermal antigen thought to play a role in cell adhesion, was mapped to chromosome bands 17q11-q12, placing it in the vicinity of the gene for the genetic disorder neurofi-bromatosis ...
A microsatellite polymorphism associated with the PLC1 (phospholipase C) locus: Identification, mapping, and linkage to the MODY locus on chromosome 20
(Elsevier, 1992-07)
A highly polymorphic (dC-dA)n[middle dot](dG-dT)n dinucleotide repeat at the PLC1 locus on human chromosome 20 has been identified. Primers flanking the dinucleotide repeat were used for PCR amplification of the repeat ...
Dual role for the zeste-white3/shaggy -encoded kinase in mesoderm and heart development of Drosophila
(John Wiley & Sons, Inc., 1998)
A Drosophila homolog of the serine/threonine kinase GSK-3β, encoded by the zest-white3/shaggy gene ( zw3 ), has been implicated as a maternally provided antagonist of zygotic signaling by the secreted segmentation gene ...
Chromosomal Localization of Four Human VH1-like Protein-Tyrosine Phosphatases
(Elsevier, 1994-07-15)
Four human protein-tyrosine phosphatase (PTPase) genes of the VH1-like subclass were cloned by low-stringency screening of a genomic library. These genes were localized to their respective chromosomes by G-banding and ...
The gustatory competence of the lingual epithelium requires neonatal innervation
(Elsevier, 1993-04-16)
The rat vallate papilla is bilaterally innervated by the IXth nerve whose axons are required for the normal development of its several hundred taste buds. Temporary denervation during the developmental sensitive period for ...
Cell cycle of Chlorella vulgaris can deviate from the synchronous binary division model
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-06)
Conditioned medium from high density Chlorella vugaris cultures was freeze dried extracted into ethanol. The ethanol was volatilized and the resulting powder then introduced with C. vulgaris photoautotrophic cultures which ...
Initiation of poly-N-acetyllactosamine chain biosynthesis occurs preferentially on complex multiantennary asparagine-linked oligosaccharides
(Elsevier, 1990-08-01)
An N-acetyl-[beta]--glucosaminyltransferase activity involved in the initiation of poly-N-acetyllactosamine chain biosynthesis can be solubilized from Ehrlich ascites tumor cell microsomal membranes. The ability of this ...
Determination of the mutations responsible for the lesch-nyhan syndrome in 17 subjects
(Elsevier, 1991-06)
Hypoxanthine -- guanine phosphoribosyltransferase (HPRT) is a purine salvage enzyme that catalyzes the conversion of hypoxanthine to inosine monophosphate and guanine to guanosine monophosphate. Previous studies of mutant ...
