The Mpz (myelin protein zero) gene codes for the principal component of myelin in the peripheral nervous system, and mutations in this gene cause human peripheral myelinopathies. Expression of the Mpz gene is controlled by two major transactivators that coordinate Schwann cell development: Egr2/Krox20 and Sox10. Our in vivo ChIP-chip analysis in myelinating peripheral nerve identified major sit...

To clarify carbon source-dependent control of the glycolytic pathway in the yeast Saccharomyces cerevisiae, we have initiated a study of transcriptional regulation of the pyruvate kinase gene (PYK). By deletion analysis of the 5'-noncoding region of the PYK gene, we have identified an upstream activating sequence (UASPYK1) located between 634 and 653 nucleotides upstream of the initiating ATG c...

pet56, his3, and ded1 are adjacent but unrelated genes located on chromosome XV of the yeast Saccharomyces cerevisiae. his3 and pet56 are transcribed in opposite directions from initiation sites separated by approximately equal to 200 base pairs. Under normal growth conditions, both genes are transcribed at a similar basal level. Deletion analysis of the his3 gene indicates that the upstream pr...

An Escherichia coli-mycobacterial shuttle vector, pJCluc, containing a luciferase reporter gene, was constructed and used to analyse the Mycobacterium tuberculosis katG promoter. A 1.9 kb region immediately upstream of katG promoted expression of the luciferase gene in E. coli and Mycobacterium smegmatis. A smaller promoter fragment (559 bp) promoted expression with equal efficiency, and was us...

Understanding the upstream-downstream linkages in hydrological processes is essential for water resources planning in river basins. Although there are many studies of individual aspects of these processes in the Himalayan region, studies along the length of the basins are limited. This study summarizes the present state of knowledge about linkages in hydrological processes between upstream and ...

c-ski gene product is a nuclear protein with myogenesis-promoting and transforming activities. We have analysed the effects of c-ski transfection on the promoter/enhancer activity of the upstream region of the myogenin gene during in vitro myogenesis using CAT reporter assay. When co-transfected with c-ski into myogenic C2C12 cells, promoter/enhancer activity was efficiently suppressed in proli...

A family of 13 related but divergent vsp genes was recently found in the chromosome of the bovine pathogen Mycoplasma bovis. The vsp genomic locus was shown to undergo high-frequency rearrangements and to mediate phenotypic switching of variable lipoprotein antigens (Vsps) on the mycoplasma cell surface. Here we report that the vsp gene repertoire is subject to changes. Genetic analysis of M. b...

We consider the interaction of free-stream disturbances with the leading edge of a body and its effect on the transition point. We present a method which combines an asymptotic receptivity approach, and a numerical method which marches through the Orr-Sommerfeld region. The asymptotic receptivity analysis produces a three deck eigensolution which in its far downstream limiting form, produces an...

Agouti-related protein encodes a neuropeptide that stimulates food intake. Agrp expression in the brain is restricted to neurons in the arcuate nucleus of the hypothalamus and is elevated by states of negative energy balance. The molecular mechanisms underlying Agrp regulation, however, remain poorly defined. Using a combination of transgenic and comparative sequence analysis, we have previousl...
