1 Ethanol and isopentanol increase CYP3A and CYP2E in primary cultures of human hepatocytes. isopentyl alcohol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 Ethanol and isopentanol increase CYP3A and CYP2E in primary cultures of human hepatocytes. isopentyl alcohol cytochrome P450 family 2 subfamily E member 1 Homo sapiens
3 Isopentanol, the major higher chain alcohol in alcoholic beverages, also induced CYP3A and CYP2E1. isopentyl alcohol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
4 Isopentanol, the major higher chain alcohol in alcoholic beverages, also induced CYP3A and CYP2E1. isopentyl alcohol cytochrome P450 family 2 subfamily E member 1 Homo sapiens
5 Ethanol and isopentanol were each more potent and more effective at inducing CYP3A in the human hepatocytes than was previously shown in cultured rat hepatocytes. isopentyl alcohol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
6 Steady-state levels of CYP3A3/4 mRNA were increased by both ethanol and isopentanol. isopentyl alcohol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
7 Ethanol and isopentanol induced immunoreactive CYP3A to a greater extent than did phenobarbital. isopentyl alcohol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
8 In one human hepatocyte culture, the lowest concentration of isopentanol tested increased CYP3A protein to an amount similar to that increased by rifampicin. isopentyl alcohol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
9 In another human hepatocyte culture, however, the amount of immunoreactive CYP3A increased by isopentanol was less than that increased by rifampicin. isopentyl alcohol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
10 In this latter culture, the steady-state levels of CYP3A3/4 mRNA increased by 0.1 mM isopentanol and 1 microM rifampicin were similar. isopentyl alcohol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
11 This is the first finding of induction of CYP3A in human hepatocytes by ethanol or isopentanol. isopentyl alcohol cytochrome P450 family 3 subfamily A member 4 Homo sapiens
