Region specific expression of furin mRNA in the rat brain
(Elsevier, 1993-01-04)
The distribution of furin mRNA was examined in the rat central nervous system. Northern blot analysis reveals the presence of a 4.4 kb band in all brain tissues examined. In situ hybridization analysis of frozen rat brain ...
Microclimatic changes and the indirect loss of ant diversity in a tropical agroecosystem
(Springer-Verlag, 1996-11)
Recent changes in the coffee agroecosystem of Costa Rica were used to study the mechanism of biodiversity loss in transforming agroecosystems, focusing on the ground-foraging ant community. Coffee farms are being transformed ...
Assignment of the human CRABP-II gene to chromosome 1q21 by nonisotopic in situ hybridization
(Springer-Verlag, 1992-07)
Two highly conserved forms of cellular retinoic acid binding protein (CRABP-I and CRABP-II) have been described, and one, CRABP-II, is highly expressed in human skin. We have utilized a 10-kb fragment containing the human ...
Immunochemical Identification Of The 1,25‐Dihydroxyvitamin D 3 Receptor Protein In Human Heart
(Blackwell Publishing LtdWiley Periodicals, Inc., 1996-09)
Expression patterns of threespine stickleback Hox genes and insights into the evolution of the vertebrate body axis
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-07)
Understanding the patterning mechanisms that operate to promote differentiation of individual segments along the main body axis is an important goal of both developmental and evolutionary biology. In order to gain a better ...
Naturally occurring genetic variation affects Drosophila photoreceptor determination
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-02)
The signal transduction pathway controlling determination of the identity of the R7 photoreceptor in the Drosophila eye is shown to harbor high levels of naturally occurring genetic variation. The number of ectopic R7 ...
Comparative gene transfer efficiency of low molecular weight polylysine DNA-condensing peptides
(Munksgaard International PublishersBlackwell Publishing Ltd, 1999-10)
In a previous report (M.S. Wadhwa et al . (1997) Bioconjugate Chem. 8, 81–88), we synthesized a panel of polylysine-containing peptides and determined that a minimal repeating lysine chain of 18 residues followed by a ...
Sequence and developmental expression of amphioxus AmphiNk2–1 : insights into the evolutionary origin of the vertebrate thyroid gland and forebrain
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-03)
We characterized an amphioxus NK-2 homeobox gene ( AmphiNk2–1 ), a homologue of vertebrate Nkx2–1 , which is involved in the development of the central nervous system and thyroid gland. At the early neurula stage of ...
