2- amino- 3,4- dimethylimidazo(4,5- f)quinoline (MeIQ)

03/01/2016 - "However, the comparative tumor-initiating potential of AαC, MeIQ, and AOM is unknown. "
05/25/1998 - "As we previously reported, administration of 300 ppm of MeIQ in a diet for 12 weeks induced lacI mutants at the highest frequency in colonocytes, and at only less than one-tenth of the colon in cells of the liver, forestomach and bone marrow, indicating no direct correlation between the lacI mutant frequency (MF) and cancer incidence (CI). "
05/25/1998 - "No direct correlation between mutant frequencies and cancer incidence induced by MeIQ in various organs of Big Blue mice."
04/01/1997 - "The mutational characteristics of MeIQ in the lacI gene coincided well with those in the Ha-ras gene of MeIQ-induced mouse forestomach tumors and rat Zymbal gland tumors. "
02/01/1997 - "p53 mutations in MeIQ-induced mouse forestomach tumors."

05/25/1998 - "With the administration of 300 ppm of MeIQ in their diet for 92 weeks, the Big Blue female mice developed intestinal tumors and hepatocellular carcinomas. "
11/01/1986 - "The incidences of liver tumors (hepatocellular carcinomas and hepatocellular adenomas) in female mice given 0.04 and 0.01% MeIQ were significantly higher than those in controls. "
07/30/2003 - "In this study, we screened liver tumors induced by 2-amino-3,4-dimethylimidazo[4,5-f]quinoline (MeIQ) in CDF1 mice for beta-catenin and APC mutations and other genetic alterations shown to occur in human hepatocellular carcinomas (HCC), including mutations in the p53 and H-ras genes, c-myc amplification and E-cadherin promoter methylation. "
11/01/1999 - "In order to study the mutagenic effects of heterocyclic aromatic amines (HAAs) in cells of human origin, five compounds, namely 2-amino-3-methyl-imidazo[4,5-f]quinoline (IQ), 2-amino-3, 4-dimethyl-imidazo[4,5-f]quinoline (MeIQ), 2-amino-3, 8-dimethyl-imidazo[4,5-f]quinoxaline (MeIQx), the pyridoimidazo derivative 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) and 3-amino-1,4-dimethyl-5H-pyrido[4,3-b]indole (Trp-P-1), were tested in micronucleus (MN) assays with a human derived hepatoma (HepG2) cell line. "

06/01/1998 - "In this paper, we demonstrate the induction of chromosome aberrations in mice chronically exposed to MeIQ in their diet. "
06/01/1998 - "Chromosome aberrations induced in mice by chronic feeding of 2-amino-3,4-dimethylimidazo[4,5-f]quinoline (MeIQ)."
09/01/1992 - "Glu-P-2, IQ, MeIQ, harman, and harmine did not induce chromosome aberrations by themselves at the concentrations used in this study. "
09/01/1992 - "A alpha C, MeA alpha C, Glu-P-1, Glu-P-2, IQ, MeIQ, harman and harmine increased chromosome aberrations only in the presence of S9 mix. "

03/01/2015 - "This study suggests that high MeIQ and total HCA estimates are positively associated with colorectal adenoma risk. "
03/01/2015 - "High intake of 2-amino-3,4-dimethylimidazo[4,5-f]quinoline (MeIQ) and total HCA was associated with an increased risk of colorectal adenoma in women but not in men. "
07/27/2021 - "A statistically significant positive association was found between 2-amino-3,4-dimethylimidazo [4,5-f] quinoline (MeIQ) and the risk of colorectal adenoma and between individual and total HAAs and the risk of prostate cancer. "

06/01/1990 - "As dietary feeding of IQ induces liver, lung and forestomach tumours, and MeIQ induces liver and forestomach tumours in this mouse strain, these binding levels do not correlate with the susceptibility of the organs to carcinogenesis induced by these compounds; the results may indicate the importance of additional factors in determining organ specificity of carcinogenicity."
02/29/1992 - "This finding together with the previous reports on squamous cell carcinomas of the rat Zymbal gland suggest that MeIQ induces a specific type of mutation at a specific site of the Ha-ras gene during squamous cell carcinogenesis, in a species-independent manner."
01/01/1995 - "Our results show that our PCR-SSCP analysis system is efficient for detecting p53 mutations in mouse genomic DNA and that alteration of the p53 gene plays a significant role in MeIQ-induced mouse forestomach carcinogenesis."
02/01/1997 - "It was therefore used to analyse the role of p53 gene mutations in forestomach carcinogenesis induced by MeIQ, by examining four original tumors, one papilloma, two primary carcinomas and one lymph node metastasis. "
05/01/1994 - "Potential synergism between 10 carcinogenic heterocyclic amines [3-amino-1,4-dimethyl-5H-pyrido[4,3-b]indole (Trp-P-1), 3-amino-1-methyl-5H-pyrido[4,3-b]indole (Trp-P-2), 2-amino-6 methyldipyrido[1,2-a:3',2'-d]imidazole (Glu-P-1), 2-amino-dipyrido[1,2-a:3',2'-d]imidazole (Glu-P-2), 2-amino-3-methylimidazo[4,5-f]quinoline (IQ), 2-amino-3,4-dimethyl-imidazo[4,5-f]quinoline (MeIQ), 2-amino-3,8-dimethyl-imidazo[4,5-f]quinoxaline (MeIQx), 2-amino-3-methyl-9H-pyrido[2,3-b]indole (MeA alpha C), 2-amino-9H-pyrido[2,3-b]indole (A alpha C) and 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP)] in rat liver carcinogenesis was examined.
