Apparent cytochrome gene dose effects in F-lac and F-gal heterogenotes of Escherichia coli.
(Elsevier: Archives of Biochemistry and Biophysics, 1972-06)The levels of b- and c-type cytochromes and cytochromes a1 and a2 are elevated in a partial diploid strain of E. coli carrying the F2-gal episome under a variety of different growth conditions. Only the levels of b- and ... -
Origins of high sequence selectivity: a stopped-flow kinetics study of DNA/RNA hybridization by duplex- and triplex-forming oligonucleotides
(The American Chemical Society: Biochemistry, 1995-08-01)Stopped-flow UV kinetics and thermal denaturation experiments are used to examine the origins of high sequence selectivity and binding affinity of circular triplex-forming oligonucleotides with single-stranded DNA/RNA ... -
Horseradish peroxidase Phe172-->Tyr mutant. Sequential formation of compound I with a porphyrin radical cation and a protein radical.
(Waverly: Journal of Biological Chemistry, 1995-08-04)A gene coding for the F172Y mutant of horseradish peroxidase isozyme C (HRP) has been constructed and expressed in both Spodoptera frugiperda (SF-9) and Trichoplusia ni egg cell homogenate (HighFive) cells. Homology modeling ... -
Chemical carcinogen in vitro testing: a method for sizing cell nuclei in the nuclear enlargement assay
(Elsevier: Toxicology, 1980)The observation that cells often respond to carcinogens by nuclear enlargement has suggested that this property might be useful to develop a short-term screening test for such compounds. Previous methods for detecting ... -
Papillomavirus DNA replication
(Humana Press: Methods in Molecular Medicine, 1999-09)Papillomavirus genomes replicate and are maintained as stable extrachromosomal plasmid DNA (episomes) in many cell lines. This process requires the viral E1 and E2 proteins and the origin of replication. The minimal origin ... -
Repression of HPV16 early region transcription by the E2 protein
(Elsevier: Virology, 2006-07-20)HPV16 DNA is often integrated in cancers, disrupting the E1 or E2 genes. E2 can repress the E6/E7 promoter, but other models have been proposed to explain why integration promotes malignant progression. E1 and E2 are ... -
NF-κB Activation is delayed in mouse L929 cells infected with interferon suppressing, but not inducing, vesicular stomatitis virus strains
(Elsevier: Virology, 1996-03-01)Vesicular stomatitis virus (VSV) mutant T1026R1 of the Indiana (IN) serotype is a good inducer of interferon (IFN). This mutant was used to study the activation of NF-κB, a transcription factor necessary for IFN induction, ... -
Tree eye endothelial cells undergo apoptosis after serum starvation
(Association for Research in Vision and Ophthalmology: Investigative Ophthalmology and Visual Science, 2002)Purpose: Several explanations have been suggested for why endothelial cells undergo apoptosis in the regressing blood vessels found in the newborn rat eye. These explanations hypothesize that apoptosis occurs due to lack ... -
Nutrient deprivation may be a poor inducer of apoptosis in the newborn rat eye
(Association for Research in Vision and Ophthalmology: Investigative Ophthalmology and Visual Science, 2003)Purpose: The hyaloid vasculature of the newborn rat eye persists after birth and regresses postnatally. One hypothesis is that regression occurs due to a decrease in blood flow to the hyaloid after retinal development and ... -
The microarray revolution
(Elsevier: Biochemistry and Molecular Biology Education, 2004-07)In recent years, microarray analysis has become a key experimental tool, enabling the analysis of genome-wide patterns of gene expression. This review approaches the microarray revolution with a focus upon four topics: 1) ... -
Apoptosis of the hyaloid vessels in vivo and in vitro in the newborn rat eye
(Association for Research in Vision and Ophthalmology: Investigative Ophthalmology and Visual Science, 2004)Purpose: In the newborn rat eye, the hyaloid vasculature persists after birth and regresses postnatally. Several studies have shown that apoptosis plays a role in this regression although the mechanism is unknown. Apoptosis ... -
Visualization of the regression of the hyaloid vasculature and retinal vessel formation in the newborn rat using FITC/Dextran
(Association for Research in Vision and Ophthalmology: Investigative Ophthalmology and Visual Science, 2005)Purpose: The regression of the pupillary membrane and hyaloid vasculature of the eye was observed in the newborn rat from postpartum days 1–36 by injection of FITC–dextran. We also observed the development of the retinal ... -
5-Bromodeoxyuridine does not affect development of the sea urchin, Arbacia punctulata
(Elsevier: Experimental Cell Research, 1978-06)Development of Arbacia punctulata embryos in the presence of bromodeoxyuridine (BUdR) was investigated under conditions which allowed about 20% substitution of BUdR for thymidine residues in DNA. Development was essentially ... -
Confocal imaging of the regression of the rat hyaloid vasculature
(Association for Research in Vision and Ophthalmology: Investigative Ophthalmology and Visual Science, 2006)Purpose: Regression of the hyaloid/fetal vessel system was studied in the newborn rat using confocal microscopy. The hyaloid vasculature composed of the hyaloid artery (HA), vasa hyaloidia propia (VHP), tunica vasculosa ... -
Cleaveable CD40Ig fusion proteins and the binding to sgp39
(Elsevier: Journal of Immunological Methods, 1995-12-15)Recombinant immunoglobulin (Ig) fusion proteins of cell surface and intracellular proteins have wide applications. For example, fusion proteins have been used in the isolation, identification and study of ligands and the ... -
Rapid, room temperature, high-density hydrogen adsorption on single-walled carbon nanotubes at atmospheric pressure assisted by a metal alloy
