Pentobarbital depressed macromolecular synthesis in Ehrlich ascites cells in vitro, and this depression was proportional to a decrease in oxygen consumption. However, survival time of animals bearing Ehrlich ascites cells was unaffected by pentobarbital. The acute toxicity of the drug was greatly enhanced by the presence of the tumor. Sleeping time was(More)
The mouse T-lymphoma (S-49) cell line is useful for individually studying RNA- and DNA-directed effects of 5-fluoropyrimidines. On the basis of their metabolic activation, biochemical effects on pyrimidine nucleotide metabolism, and biological toxicity, we hve established that incubation of S-49 cells with 5-fluorodeoxyuridine produces only DNA-directed(More)
Abetalipoproteinemia (ABL) is a rare Mendelian disorder of lipid metabolism due to genetic deficiency in microsomal triglyceride transfer protein (MTP). It is associated with defects in MTP-mediated lipid transfer onto apolipoprotein B (APOB) and impaired secretion of APOB-containing lipoproteins. Recently, MTP was shown to regulate the CD1 family of lipid(More)
The actions of 6-thioguanine (TG) and 6-mercaptopurine (MP) were compared in Chinese hamster ovary (CHO) cells. Several differences were noted between these two agents. TG caused a greater maximal loss of clonogenicity, leaving about one log fewer survivors than did MP, although the cells killed by MP appeared to succumb much more rapidly than those killed(More)
The effect of dietary administration of 0.5% ethoxyquin (EQ) on the in vivo induction of enzymes and effect on aflatoxin B1 (AFB1)-DNA binding in liver and the consequent in vitro metabolism of AFB1 by male Fischer F344 rat liver-derived fractions have been examined. EQ increased microsomal cytochrome P-450s, in particular those isozymes classed as(More)
Limited English proficiency (LEP), defined as a limited ability to read, speak, write, or understand English, is associated with health disparities. Despite federal and state requirements to translate health information, the vast majority of health materials are solely available in English. This project investigates barriers to translation of health(More)
The rate of DNA synthesis was determined in rats with developing and established two-kidney, one clip renal hypertension. Rate of DNA synthesis was measured as [3H]thymidine incorporation into DNA per hour. After stenosis of the renal artery, blood pressure increased over a 2-week period. Five days after clipping, there was an increase in the rate of aortic(More)
