The antimutagenic effect of monoterpenes against UV-irradiation-, 4NQO- and t-BOOH-induced mutagenesis in coli [PDF]
Archives of Biological Sciences, 2011 The aim of this work was to investigate the antimutagenic potential of monoterpenes from sage and basil in Escherichia coli. The mutagenic potential of monoterpenes was pre-screened with Salmonella/microsome reversion assay in strain TA100 and no ...

Liver/kidney microsome antibody type 1 and hepatitis C virus infection
Hepatology, 1992 Recent studies have shown that hepatitis C virus antibodies are present in a large proportion of patients with autoimmune hepatitis type 2. We have studied 83 patients with liver/kidney microsome antibody‐positive type 1 hepatitis.

Statistical analysis of the Ames Salmonella/microsome test.
Proceedings of the National Academy of Sciences of the United States of America, 1981 A family of statistical models for analysis of Ames Salmonella/microsome test data is constructed that considers mutation and toxicity as competing risks and allows hyper-Poisson variability.

ACBP and cholesterol differentially alter fatty acyl CoA utilization by microsomal ACAT
Journal of Lipid Research, 2003 Microsomal acyl CoA:cholesterol acyltransferase (AC57) is stimulated in vitro and/or in intact cells by proteins that bind and transfer both substrates, cholesterol, and fatty acyl CoA.

Abnormal subcellular distribution of GLUT4 protein in obese and insulin-treated diabetic female dogs
Brazilian Journal of Medical and Biological Research, 2004 The GLUT4 transporter plays a key role in insulin-induced glucose uptake, which is impaired in insulin resistance. The objective of the present study was to investigate the tissue content and the subcellular distribution of GLUT4 protein in 4- to 12-year-

Smooth microsomes. a trap for cholesteryl ester formed in hepatic microsomes.
Journal of Biological Chemistry, 1980 Acyl-CoA:cholesterol acyltransferase was found predominantly (85%) in RNA-rich microsomes, the rest being in RNA-poor and smooth microsomes. However, the esterified cholesterol concentration of smooth microsomes was 2-fold greater than that of RNA-rich microsomes, suggesting the possibility of an interaction between RNA-rich and smooth microsomes.

Journal of Lipid Research, 2007 Human cytochrome P450 4F2 (CYP4F2) catalyzes the initial ω-hydroxylation reaction in the metabolism of tocopherols and tocotrienols to carboxychromanols and is, to date, the only enzyme shown to metabolize vitamin E.

Antimutagenic effect of essential oil of sage (Salvia officinalis L.) and its fractions against UV-induced mutations in bacterial and yeast cells [PDF]
Archives of Biological Sciences, 2005 The inhibition of spontaneous and UV-induced mutations by essential oil (EO) of sage (Salvia officinalis L.) and its fractions F1-F5 containing different proportions of mono- and sesquiterpenes was studied with the Salmonella/microsome, E.
