Redistribution of 5-Lipoxygenase and Cytosolic Phospholipase A2 to the Nuclear Fraction upon Macrophage Activation
(Elsevier, 1993-10-15)
Both the cytosolic phospholipase A2 and 5-lipoxygenase enzymes redistribute from the high-speed supernatant to a particulate fraction upon cell activation with associated leukotriene synthesis, but the subcellular site to ...
Stimulation of myenteric plexus neurite outgrowth by insulin and insulin-like growth factors I and II
(Elsevier, 1992)
A defined culture medium containing insulin, insulin-like growth factor I (IGF-I) or insulin-like growth II (IGF-II) supported morphological development of myenteric plexus neurons derived from neonatal guinea pigs. Insulin ...
The genes for the inter-α-inhibitor family share a homologous organization in human and mouse
(Springer-Verlag, 1992-12)
Inter-α-inhibitor ( IαI ) and related molecules in human are comprised of three evolutionarily related, heavy (H) chains and one light (L) chain, also termed bikunin. The latter originates from a precursor molecule that ...
Expression of carbonic anhydrase II (CA II) promoter-reporter fusion genes in multiple tissues of transgenic mice does not replicate normal patterns of expression indicating complexity of CA II regulation in vivo
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1995-12)
Although the proximal, 5′ 115 bp of the human carbonic anhydrase II (CA II) gene was sufficient for expression of a reporter gene in some transfected cell lines, we found previously that 1100 bp of this promoter (or 500 ...
The Gunnera symbiosis: DNA restriction fragment length polymorphism and protein comparisons of Nostoc symbionts
(Springer-Verlag; Springer-Verlag New York Inc., 1990-05)
Cyanobacteria separated from symbiosis with several species of the angiosperm Gunnera were comparatively characterized and correlated with the locales and taxonomy of their host plants. All were identified as strains of ...
Coordinate control and variation in X-linked gene expression among female mice
(Springer-Verlag; Springer-Verlag New York Inc., 1997-11)
In normal female mammals, one of the two X Chromosome (Chr) homologs per cell is silenced coordinately during early embryogenesis. The genes located on the inactivated X homolog are predicted to be influenced by the same ...
Adenosine depresses spontaneous transmitter release from frog motor nerve terminals by acting at an A1-like receptor
(Elsevier, 1990)
Adenosine (1[mu]M to 1mM) depressed spontaneous transmitter release from frog motor nerve terminals without producing any observable postsynaptic effects. Since this action of adenosine was blocked by 20[mu]M theophylline ...
Heterogeneity and organization of the ribosomal RNA genes of Cucurbita maxima
(Kluwer Academic Publishers; Springer Science+Business Media, 1990-06)
Thirty-six clones were recovered from Cucurbita maxima genomic DNA which had been enriched for rDNA and cleaved at the unique repeat unit Hin d III site. Twenty-nine of these, which contain complete rDNA units, were compared ...
Amino acid sequence of pheromone-inducible surface protein in Enterococcus faecalis, that is encoded on the conjugative plasmid pPD1
(Elsevier, 1990-07-30)
The major pheromone-inducible protein, PD78, believed to contribute to bacterial conjugation, was purified from Enterococcus (formerly Streptococcus) faecalis cells containing the plasmid pPD1. A cloned EcoRI-Bg1II 3.6-kbp ...
Maximization of Daily Canopy Photosynthesis: Effects of Herbivory on Optimal Nitrogen Distribution
(Elsevier, 1994-08-07)
Recent models have shown that higher leaf nitrogen concentration per unit area maximizes nitrogen use efficiency with increasing light intensity. As a result, total canopy photosynthesis is maximized when nitrogen ...
