H2O2 and Tumor Necrosis Factor-α Activate Intercellular Adhesion Molecule 1 (ICAM-1) Gene Transcription through Distinct cis-Regulatory Elements within the ICAM-1 Promoter (*)
We investigated the mechanisms by which H2O2 increases intercellular adhesion molecule 1 (ICAM-1; CD54) expression in endothelial cells. The H2O2-induced increase in ICAM-1 mRNA was inhibited by… Expand

Hydrogen peroxide-induced increase in endothelial adhesiveness is dependent on ICAM-1 activation.
Reactive oxygen radicals (ROS) generated by phagocytes promote human polymorphonuclear leukocyte (PMN) adhesion to human umbilical vein endothelial cells (EC). We determined the effects of hydrogen… Expand

Endothelin-1 stimulates DNA synthesis and proliferation of pulmonary artery smooth muscle cells.
Endothelin-1 (ET-1), a 21-amino acid peptide released from the endothelium, elicits a variety of biological effects that include vascular smooth muscle cell (VSMC) contraction, release of secondary… Expand

Fluorometric analysis of DNA in cell cultures.
A simple, reproducible fluorescent assay has been described which can be used confidently at microgram and submicrogram levels. The method is most suitable for cell cycle and cell growth analysis… Expand

Mosaicism in female hybrid hares heterozygous for glucose-6-phosphate dehydrogenase. VI. Production of monotypism in the aortas of 4 of 10 mosaic hares fed cholesterol oxidation products.
The normal aortic tissue of black women heterozygous for glucose-6-phosphate dehydrogenase (G-6-PD) usually consists of two cell phenotypes (mosaicism). By electrophoresis two G-6-PD types are… Expand

Mosaicism in female hybrid hares heterozygous for glucose-6-phosphate dehydrogenase. VII. Evidence for selective advantage of one phenotype over the other in ditypic samples from aortas of hares fed…
In a previous study the authors demonstrated monotypic foci, all of timidus type, in the atherosclerotic lesions and normal aortic tissue of glucose-6-phosphate dehydrogenase (G-6-PD) mosaic hares… Expand

The biosynthesis of catecholamines in two genera of protozoa.
Abstract Norepinephrine was isolated from the flagellated protozoan, Crithidia fasciculata, and the ciliated protozoan, Tetrahymena pyriformis, the former having less than one-half that of the… Expand

Effects of salicylate on RNA polymerase activity and on the incorporation of orotic acid and thymidine into the nucleic acids of rat foetuses in vitro
Salicylate (10 mM) significantly inhibited the activity of RNA polymerase and the incorporation of radioactivity from orotic acid‐5‐3H and thymidine‐6‐3H into whole 13 day and 16 day rat foetuses.… Expand
