induction of CYP1A1 and/or 1A2-mediated increase in ellipticine oxidative activation to 13-hydroxy- and 12-hydroxyellipticine, the metabolites generating two major DNA adducts in human and rat livers. ellipticine 52-63 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 95-101 22167207-10 2011 Based on these studies, we attribute most of the enhancing effects of VPA and TSA on ellipticine cytotoxicity to enhanced ellipticine-DNA adduct formation caused by an increase in levels of cytochrome b5, CYP3A4 and CYP1A1 in neuroblastoma cells. ellipticine 85-96 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 216-222 22167207-10 2011 Based on these studies, we attribute most of the enhancing effects of VPA and TSA on ellipticine cytotoxicity to enhanced ellipticine-DNA adduct formation caused by an increase in levels of cytochrome b5, CYP3A4 and CYP1A1 in neuroblastoma cells. ellipticine 122-133 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 216-222 20027146-9 2009 This effect might be associated with formation of two covalent ellipticine-derived DNA adducts, identical to those formed by 13-hydroxy- and 12-hydroxyellipticine, the ellipticine metabolites generated by CYP1A1, 1B1 and 3A4, lactoperoxidase and cyclooxygenase 1, the enzymes expressed in U87MG cells. ellipticine 63-74 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 205-216 17656468-8 2007 The observed stimulation of DNA adduct formation by ellipticine was attributed to induction of CYP1A1 and/or 1A2-mediated increase in ellipticine oxidative activation to 13-hydroxy- and 12-hydroxyellipticine, the metabolites generating two major DNA adducts in human and rat livers. ellipticine 134-145 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 95-101 17159771-8 2006 Using the reconstituted enzymatic system, we demonstrated that the detoxication ellipticine metabolites, 7-hydroxyellipticine and 9-hydroxyellipticine, are mainly generated by CYP1A1 and 1A2, while those responsible for DNA binding, 13-hydroxy-, 12-hydroxyellipticine and ellipticine N(2)-oxide, by CYP3A1 and 2C3. ellipticine 80-91 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 176-190 16507648-4 2006 The formation of OH-flutamide was markedly inhibited by ellipticine, an inhibitor of CYP1A1/1A2, and was mainly catalyzed by the recombinant CYP1A2. ellipticine 56-67 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 85-91 12123750-3 2002 We examined a panel of genetically engineered V79 cell lines including the parental line V79MZ and recombinant cells expressing the human CYP enzymes CYP1A1, CYP1A2 or CYP3A4 for their ability to activate ellipticine. ellipticine 205-216 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 150-156 15548707-7 2004 Using recombinant human enzymes, oxidation of ellipticine to 9-hydroxyellipticine and 7-hydroxyellipticine by CYP1A1/2 and to 13-hydroxyellipticine and N(2)-oxide by CYP3A4 was corroborated. ellipticine 46-57 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 110-118 11218050-15 2001 This pattern was also confirmed using the CYP 1A1 inhibitor ellipticine. ellipticine 60-71 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 42-49 11790342-6 2000 By contrast, low concentrations (0.025-0.050 microM) of the mammalian CYP1A1 inhibitor ellipticine completely abolished EROD activity, but had no effect (up to 1 mM) on caffeine metabolism or POD activity in either species. ellipticine 87-98 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 70-76 10490621-6 1999 This negative autoregulation is abolished by ellipticine (an inhibitor of CYP1A1) and by catalase (which catalyzes H(2)O(2) catabolism), thus implying that H(2)O(2) is an intermediate. ellipticine 45-56 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 74-80 8759031-6 1996 Cotreatment with alpha-naphthoflavone (alpha NF, 1 microM) or ellipticine (ELLIP, 0.1 nM) only partially inhibited the induction of AHH activity by BaP (30 microM). ellipticine 62-73 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 132-135 8759031-6 1996 Cotreatment with alpha-naphthoflavone (alpha NF, 1 microM) or ellipticine (ELLIP, 0.1 nM) only partially inhibited the induction of AHH activity by BaP (30 microM). ellipticine 75-80 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 132-135 29471073-7 2018 Our results indicate that the underlying mechanisms whereby etoposide and ellipticine regulate CYP1A1 expression must be different and may not be linked to p53 activation alone. ellipticine 74-85 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 95-101 8474022-4 1993 The prototypic CYP1A xenobiotic inhibitor and substrate probes alpha-naphthoflavone, ellipticine, 7-ethoxycoumarin and 7-ethoxyresorufin all inhibited CYP1A1- and CYP1A2-mediated phenacetin O-deethylation as well as the high-affinity component of human liver phenacetin O-deethylase activity. ellipticine 85-96 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 151-157 29471073-4 2018 We found that etoposide and ellipticine induced CYP1A1 in TP53(+/+) cells but not in TP53(-/-) cells, demonstrating that the mechanism of CYP1A1 induction is p53-dependent; cisplatin had no such effect. ellipticine 28-39 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 48-54 29471073-4 2018 We found that etoposide and ellipticine induced CYP1A1 in TP53(+/+) cells but not in TP53(-/-) cells, demonstrating that the mechanism of CYP1A1 induction is p53-dependent; cisplatin had no such effect. ellipticine 28-39 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 138-144
