Mutational inactivation of the xeroderma pigmentosum group C gene confers predisposition to 2-acetylaminofluorene-induced liver and lung cancer and to spontaneous testicular cancer in Trp53-/- mice. (1/450)

Mice that are genetically engineered to mimic the human hereditary cancer-prone DNA repair-defective disease xeroderma pigmentosum (XP) are highly predisposed to UV radiation-induced skin cancer. It is not clear, however, whether XP mice or humans are predisposed to cancers in other tissues associated with exposure to environmental carcinogens. To test the importance of nucleotide excision repair in protection against chemical carcinogenesis in internal organs, we treated XPC mutant (XPC-/-) mice with 2-acetylaminofluorene and NOH-2-acetylaminofluorene. We observed a significantly higher incidence of chemically induced liver and lung tumors in XPC-/- mice compared with normal and heterozygous littermates In addition, the progression of liver tumors in XPC-/- Trp53+/- mice is accelerated compared with XPC-/- Trp53+/+ animals. Finally, we demonstrate a higher incidence of spontaneous testicular tumors in XPC-/- TrpS3-/- double mutant mice compared with XPC+/+ Trp53-/- mice.  (+info)

Pseudoenzymatic reduction of N-hydroxy-2-acetylaminofluorene to 2-acetylaminofluorene mediated by cytochrome P450. (2/450)

N-hydroxy-2-acetylaminofluorene (N-OH-AAF) was reduced to 2-acetylaminofluorene by rat liver microsomes in the presence of both NAD(P)H and FAD under anaerobic conditions. The microsomal reduction proceeds as if it were an enzymatic reaction. However, when the microsomes were boiled, the activity was not abolished, but was enhanced. The activity was also observed with cytochrome P450 2B1 alone, without NADPH-cytochrome P450 reductase, in the presence of these cofactors. Hematin also exhibited a significant reducing activity in the presence of both a reduced pyridine nucleotide and FAD. The activities of microsomes, cytochrome P450 2B1 and hematin were also observed upon the addition of photochemically reduced FAD instead of both NAD(P)H and FAD. The microsomal reduction of N-OH-AAF appears to be a non-enzymatic reaction by the reduced flavin, catalyzed by the heme group of cytochrome P450.  (+info)

Effect of detergents on the N-and ring-hydroxylation of 2-acetamidofluorene by hamster liver microsomal preparations. (3/450)

Effects of detergents such as cholate, deoxycholate and Triton X-100 were studied on N-and ring-hydroxylation of 2-acetamidofluorene by reconstituted and unresolved microsomal systems from livers of hamsters pretreated with 3-methylcholanthrene. Triton X-100 (2.5 mg/nmol of cytochrome P-448) inhibited N-and ring-hydroxylation by wholemicrosomal preparations by 40 and 90% respectively Deoxycholate at the same concentration inhibited both hydroxylations completely, whereas cholate inhibited N-and ring-hydroxylation by 40 and 50% respectively. In reconstitution studies, the presence of Triton X-100(0.5-1.0mg/nmol of cytochrome P-448) along with unsolubilized cytochrome P-448 fraction and solubilized reductase fraction increased N-hydroxylation to an appreciable extent compared with ring-hydroxylation. Both cholate and deoxycholate at 0.5-1.0 mg concentrations had a greater stimulatory effect on ring-than on N-hydroxylation activity in such a reconstituted system.  (+info)

Bone marrow as a potential source of hepatic oval cells. (4/450)

Bone marrow stem cells develop into hematopoietic and mesenchymal lineages but have not been known to participate in production of hepatocytes, biliary cells, or oval cells during liver regeneration. Cross-sex or cross-strain bone marrow and whole liver transplantation were used to trace the origin of the repopulating liver cells. Transplanted rats were treated with 2-acetylaminofluorene, to block hepatocyte proliferation, and then hepatic injury, to induce oval cell proliferation. Markers for Y chromosome, dipeptidyl peptidase IV enzyme, and L21-6 antigen were used to identify liver cells of bone marrow origin. From these cells, a proportion of the regenerated hepatic cells were shown to be donor-derived. Thus, a stem cell associated with the bone marrow has epithelial cell lineage capability.  (+info)

Resistance to the promotion of glutathione S-transferase 7-7-positive liver lesions in Copenhagen rats. (5/450)

Previously, we have shown that Copenhagen (Cop) rats are highly resistant to the induction of putative preneoplastic, glutathione S-transferase 7-7 (GST 7-7)-positive liver lesions following treatment with a modified resistant hepatocyte protocol. The objective of the current study was to establish the time course for the development of resistance and examine potential resistance mechanisms in Cop rats using F344 rats as susceptible controls. Male Cop and F344 rats (n = 25), 7-8 weeks of age, were initiated with diethylnitrosamine (200 mg/kg) and promoted 3 weeks later with four doses of 2-acetylaminofluorene (20 mg/kg) and a 2/3 partial hepatectomy (PH). Groups of rats from each strain were killed on days 2, 4, 7, 14 and 21 post-PH, 2 h after receiving bromodeoxyuridine. Cop livers contained similar numbers of GST 7-7-positive lesions to F344 livers on days 2 and 4 post-PH. The percent volume of liver occupied by these lesions did not differ between the strains on days 2, 4 and 7 post-PH. On day 14, however, approximately 29% of the liver volume in F344 rats was occupied by lesions, whereas in Cop rats this was significantly less (approximately 9%, P < 0.001). On day 21, lesions occupied approximately 58% of F344 rat livers and only approximately 6% of Cop livers. Despite these differences, the labeling index of hepatocytes was not significantly different between the strains at any time point, either within lesions or within surrounding normal liver. Furthermore, the apoptotic indices were not different between the strains at any time. However, differences were found in the extent of lesion remodeling (redifferentiation) and in the pattern of oval cell response following PH in Cop livers. By day 14 post-PH, approximately 76% of Cop liver lesions showed evidence of remodeling, compared with only approximately 14% of F344 lesions. The oval cell response to PH was equivalent in the two strains up to day 4 post-PH but by day 7, in F344 livers there was extensive migration of these cells into the liver parenchyma, whereas in Cop livers, the response remained localized to the portal regions. These results suggest that Cop resistance occurs at the promotion stage and not the initiation stage of carcinogenesis. Resistance appears not to be due to a lower proliferation rate nor to a higher apoptotic rate within Cop lesions. Precocious remodeling and/or a diminished oval cell response, however, may contribute to the resistance of Cop rats to the growth of GST 7-7-positive hepatic lesions.  (+info)

Analysis of loss of heterozygosity in neoplastic nodules induced by diethylnitrosamine in the resistant BFF1 rat strain. (6/450)

Loss of heterozygosity (LOH) at specific chromosomal regions is a frequent event in poorly differentiated human hepatocellular carcinomas (HCCs), but rare in mouse HCCs. This behavior could depend on interspecies differences in mechanisms of hepatocarcinogenesis or in developmental stage of lesions. To verify if LOH is involved in rat hepatocarcinogenesis, we studied LOH frequency in slowly growing neoplastic nodules induced by Solt-Farber model in diethylnitrosamine-initiated BFF1 rats. We analyzed, with microsatellites, markers at 67 rat loci dispersed over all chromosomes, corresponding to regions homologous to those lost in human HCCs or containing hepatocellular susceptibility (Hcs) or resistance (Hcr) loci in rat and mouse. In agreement with previous findings with mouse HCCs, but at variance with human HCCs, no detectable LOH was found at any locus in rats, suggesting rare LOH involvement in neoplastic nodules, with low tendency to progress to full malignancy, of BFF1 rats.  (+info)

Development of resistance during the early stages of experimental liver carcinogenesis. (7/450)

The present study was designed to determine whether the resistant phenotype is acquired at the initiated cell stage itself or requires further exposure to a promoting regimen to express resistance. Male Fischer 344 rats were initiated with diethylnitrosamine (DENA) (200 mg/kg i.p.) and were subjected to either no further treatment or to the resistant hepatocyte (RH) model of liver tumor promotion. Six weeks later, the resistance of the focal lesions generated in these two groups to the mitoinhibitory effects of 2-acetylaminofluorene (2-AAF) was determined by subjecting the rats to two-thirds partial hepatectomy (PH) in the presence of a mitoinhibitory dose of 2-AAF (5 mg/kg i.p.) given at the time of PH. Labeling index was determined by administering multiple injections of [(3)H]thymidine. All rats were killed 48 h post-PH. While only a small percentage (23%) of the glutathione S-transferase-positive foci generated by DENA in the absence of an exogenous liver tumor promoting regimen were resistant to the mitoinhibitory effects of 2-AAF, a majority (85%) of the foci became resistant to 2-AAF following exposure to the RH model of liver tumor promotion. Further, initiated rats exposed to either 2-AAF or to CCl(4) alone, the two components of the RH model, resulted in 71% of the foci being resistant to the mitoinhibitory effects of 2-AAF. Similar patterns of results were obtained when the resistance of the foci to the mitoinhibitory effects of orotic acid, a liver tumor promoter and an inhibitor of DNA synthesis in normal hepatocytes, was monitored. These results suggest that the majority of initiated hepatocytes are not of resistant phenotype, however, they have acquired a unique ability to express resistance upon exposure to certain agents such as 2-AAF and CCl(4) or to a promoting regimen such as the RH model of liver tumor promotion.  (+info)

Modulation of the gene network connected to interferon-gamma in liver regeneration from oval cells. (8/450)

Suppression subtractive hybridization was used to clone genes associated with proliferation of oval cells in rat liver regenerating after a 70% partial hepatectomy combined with the feeding of 2-acetylaminofluorene. A subset of the identified genes comprised interferon-gamma receptor alpha subunit (IFN-gammaRalpha), gp91phox, interleukin-1beta (IL-1beta), lymphocyte function-associated molecule-1alpha (LFA-1), eukaryotic initiation factor-2-associated 67-kd protein (eIF-2-associated 67-kd protein), and alpha-fetoprotein, which constitute part of the cellular program modulated by IFN-gamma. Therefore, expression analysis performed by Northern blotting and immunohistochemistry were extended to include IFN-gamma, the IFN-gamma receptor beta subunit (IFN-gammaRbeta), three secondary response genes induced by interaction of IFN-gamma with IFN-gamma receptor complexes, ie, IL-1beta-converting enzyme (ICE), intercellular adhesion molecule-1 (ICAM-1), and urokinase-type plasminogen activator receptor (uPAR), and a cytokine inducing IFN-gamma expression, ie, interleukin-18 (IL-18). The Northern blot analysis showed that all examined genes were modulated when progenitor-like oval cells were activated and recruited for liver regeneration. Immunohistochemistry localized the subunits of the IFN-gamma receptor complex, IFN-gammaRalpha and IFN-gammaRbeta, the secondary response genes uPAR and ICAM-1, the IFN-gamma-inducing factor IL-18, and ICE to the ductular structures of oval cells. In contrast, during liver regeneration after a 70% partial hepatectomy, only modulation of IL-1beta and ICE was observed. Our results, therefore, indicate that IFN-gamma-mediated events may be particularly important when cells in the bile ductules must respond to liver damage by production of ductular oval cells.  (+info)

The sensitivity of various methods suitable for biomonitoring the exposure to genotoxicants was compared in an animal model. The results were related to the presence of genotoxic effects in the target organ. Groups of male Wistar rats were given one oral dose of 0, 0.1, 1, 10 or 200 mg 2-acetylaminofluorene (2-AAF)/5 ml dimethyl sulphoxide/kg body weight. Peripheral blood cells, excreta, liver and spleen were collected at different time intervals after dosing. Mutagenicity in urine and extracts of faeces was determined using the Ames test with Salmonella typhimurium TA98 with and without S9 and with and without ??-glucuronidase. Genotoxic effects were studied by measuring DNA-adduct formation in lymphocytes, liver and spleen, and sister-chromatid exchanges (SCEs) in lymphocytes. DNA adducts were measured with immunochemical techniques and postlabelling methods. Mutagenecity in urine and faeces, collected during the first 24 h after treatment, was detected at 2-AAF doses of 1 mg/kg b.w. and ...
Liver cirrhosis is a predominant risk factor for hepatocellular carcinoma (HCC). However, the mechanism underlying the progression from cirrhosis to HCC remains unclear. Herein we report the concurrent increase of liver progenitor cells (LPCs) and transforming growth factor-β (TGF-β) in diethylnitrosamine (DEN)-induced rat hepatocarcinogenesis and cirrhotic livers of HCC patients. Using several experimental approaches, including 2-acetylaminofluorene/partial hepatectomy (2-AAF/PHx) and 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC)-elicited murine liver regeneration, we found that activation of LPCs in the absence of TGF-β induction was insufficient to trigger hepatocarcinogenesis. Moreover, a small fraction of LPCs was detected to coexpress tumor initiating cell (T-IC) markers during rat hepatocarcinogenesis and in human HCCs, and TGF-β levels were positively correlated with T-IC marker expression, which indicates a role of TGF-β in T-IC generation. Rat pluripotent LPC-like WB-F344 cells ...

In the present study we exposed WT, p53+/−, Xpa, and Xpa/p53+/− mice to 300 ppm 2-AAF, a bladder and liver carcinogen, to compare the relative contribution of a deficiency in NER, p53, or both on tumor development in two different tumor target tissues. Under the conditions used in this study, WT mice showed no clear tumor response in the liver or the urinary bladder. This finding is in line with previous reports showing that the development of 2-AAF-induced bladder and/or liver tumors takes longer than 39 weeks (40) . In fact, sustained 2-AAF exposure would most likely have resulted in the development of both urinary bladder and liver tumors, because a clear induction of preneoplastic lesions was found in 2-AAF-treated WT mice (Table 1) ⇓ . Interestingly, NER-deficient Xpa mice were clearly susceptible to develop hepatic tumors upon 2-AAF treatment, because a significant increased number of hepatocellular adenomas and carcinomas were found (Table 1) ⇓ . Surprisingly, these mice showed no ...
A method is described for the isolation of endoplasmic reticulum and Golgi apparatus from hyperplastic liver nodules produced by discontinuous feeding of 2-acetylaminofluorene to male Wistar rats. The procedure involves three centrifugation steps and permits the separation of these cell components and their subfractions from the same sample of liver tissue with as little as 1 g, wet weight. The fractions have been characterized by chemical, enzymatic, and morphological techniques and were found to be as pure as preparations from normal tissue. Furthermore, some of the characteristic histochemical features of hyperplastic liver nodules have been quantitated by biochemical methods in the fractions. Glucose-6-phosphatase activity in the endoplasmic reticulum subfractions of nodules is approximately 15% of the corresponding value in normal livers, whereas the activity of reduced nicotinamide adenine dinucleotide phosphate: cytochrome c reductase is reduced to 85% of the normal activity. The amount ...
The Hippo-Yap signaling pathway regulates a number of developmental and adult cellular processes, including cell fate determination, tissue growth, and tumorigenesis. Members of the scaffold protein angiomotin (Amot) family interact with several Hippo pathway components, including Yap (Yes-associated protein), and either stimulate or inhibit Yap activity. We used a combination of genetic, biochemical, and transcriptional approaches to assess the functional consequences of the Amot-Yap interaction in mice and in human cells. Mice with a liver-specific Amot knockout exhibited reduced hepatic oval cell proliferation and tumorigenesis in response to toxin-induced injury or when crossed with mice lacking the tumor suppressor Nf2. Biochemical examination of the Amot-Yap interaction revealed that the p130 splicing isoform of Amot (Amot-p130) and Yap interacted in both the cytoplasm and nucleus, which involved binding of PPxY and LPxY motifs in Amot-p130 to WW domains of Yap. In the cytoplasm, ...

Biochem Biophys Res Commun 1983 Dec 28;117(3):740-5 Eriksson LC; Sharma RN; Roomi MW; Ho RK; Farber E; Murray RK. The cytosolic polypeptides of hepatocyte nodules in six models of liver carcinogenesis were analysed by SDS-polyacrylamide gel electrophoresis and their patterns compared with these of control and variously treated livers. The amount of a polypeptide of Mr 21,000 was about tenfold elevated in the cytosol of five of the six types of nodules and moderately elevated in the sixth. Certain other polypeptides, particularly one of Mr 26,000, also varied in amount, so that all of the nodules analysed could be distinguished from liver by their electrophoretic patterns. Some possible identities of the two polypeptides are discussed. Their study may have mechanistic as well as diagnostic importance.. ...

We have studied the enantioselectivity and regioselectivity of ring-hydroxylation and N-desisopropylation of R(+)- and S(-)-propranolol in microsomes from yeast expressing cytochrome P4502D6 (CYP2D6), using both NADPH and molecular oxygen (NADPH/O2) and cumene hydroperoxide-supported reactions. With NADPH/O2-supported reactions, CYP2D6 catalyzed 4- and 5-ring-hydroxylation, as well as N-desisopropylation of propranolol, although Vmax was considerably greater for ring-hydroxylation, compared with N-desisopropylation. The R/S ratios for KM and Vmax were less than unity for all three pathways. In contrast, using cumene hydroperoxide-supported reactions, CYP2D6 catalyzed 4- and 5-ring-hydroxylation, and there was negligible N-desisopropylation of propranolol. The R/S ratio for KM was less than unity, but the R/S ratio for Vmax was close to unity. The cumyl group of cumene hydroperoxide did not seem to be a selective inhibitor of N-desisopropylation, because i) cumyl alcohol (a nonalkylhydroperoxide ...
Further evidence for the preferential interaction of carcinogens with mitochondrial DNA (mtDNA) has been obtained. In rats treated with high doses of N-nitrosodimethylamine (NDMA) or N-nitroso-N-butylurea (NBU), hepatic mtDNA contains 1.4 times more O6-methyl-2-deoxyguanosine (O6-MedG) or 2.3 times more O6-butyl-2-deoxyguanosine (O6-BudG) than does nuclear DNA (nDNA). The kinetics of removal of O6-MeG from mtDNA and nDNA are similar at both high (20 mg/kg) and low (2 mg/kg) doses of NDMA, and the removal of O6-MeG can be increased by pretreating the animals with 2-acetylaminofluorene (AAF), indicating that O6-MeG is repaired in the mitochondrion by a mechanism similar to that which functions in the nucleus. In contrast, O6-BudG is removed very slowly from mtDNA and rapidly from nDNA, an observation which is consistent with the absence of a nucleotide excision mechanism in the mitochondrion and the repair of O6-BudG, predominantly by an excision mechanism, in the nucleus of mammalian cells. A ...

Pre- and post-initiation modulating effects of green tea ingestion on rat hepatocarcinogenesis Green tea;hepatocarcinogenesis;initiation;GST-P;rats; The purpose of this study was to investigate the effects of green tea ingestion on hepatocarcinogenesis before and after its initiation. Male Sprague-Dawley rats were fed an AIN76A diet with or without green tea. Initiation was induced by a single dose (200 mg/kg) of diethylnitrosamine at week 4 and 0.02% (w/w) 2-acetylaminofluorene was supplied in the diets. The control group had free access to water for 13 weeks (CTR13). Tea infusion was provided from the beginning of the experiment for 13 weeks (PRE13) or from the post-initiation stage until week 13 (POST13). Three other groups (CTR24, PRE24 and POST24) were added to examine the longer-term effects (24 weeks) with the same experimental design. The percentage area of liver sections that were positive for hepatic placental glutathione S-transferase (GST-P), which was used as a marker of preneoplastic
TY - JOUR. T1 - Inhibition of mitochondrial oxidative phosphorylation by 2-methyl-4-dimethylaminoazobenzene. AU - Kumar, P. Sai. AU - Kurup, C. K.Ramakrishna. PY - 1984/7/27. Y1 - 1984/7/27. N2 - The azodye 2-methyl-4-dimethylaminoazobenzene inhibited oxidation and phosphorylation in tightly coupled rat liver mitochondria. Phosphorylation was more sensitive to the inhibitory action of the azodye than was the oxidation of succinate or ascorbate. The oxidation of NAD+-linked substrate was severely inhibited by the compound. In submitochondrial particles, only NADH oxidation was sensitive. The site of inhibition has been identified to lie between the dehydrogenase flavoprotein and ubiquinone..

Various methods for predicting DDI with enzyme inactivators have been developed, including both static and semiphysiologic models (Galetin et al., 2006; Einolf, 2007; Obach et al., 2007; Grimm et al., 2009; Fenneteau et al., 2010; Quinney et al., 2010), each relying on kdeg for the enzyme as a key input parameter. As physiologically based pharmacokinetic modeling is more routinely applied to predict complex drug interactions, many researchers have noted improved prediction accuracy when using a CYP3A kdeg of 0.03 hour−1(Wang, 2010; Friedman et al., 2011; Yamashita et al., 2013), determined from the time course of CYP3A recovery following multiple-dose clarithromycin administration. The current approach, which resulted in an overall CYP3A kdeg of 0.0240 hour−1, relied on human hepatocytes, specifically the human HepatoPac model, as a viable in vitro surrogate of P450 regulation. Studies from our laboratories and others have characterized the activity, longevity, and functionality of the ...

Hepatic oval cells (HOCs) are considered the progeny of the intrahepatic stem cells that are found in a small population in the liver after hepatocyte proliferation is inhibited. Due to their small number, isolation and capture of these cells constitute a challenging task for immunosensor technology. This work describes the development of a 3D-printed continuous flow system and exploits disposable screen-printed electrodes for the rapid detection of HOCs that over-express the OV6 marker on their membrane. Multiwall carbon nanotube (MWCNT) electrodes have a chitosan film that serves as a scaffold for the immobilization of oval cell marker antibodies (anti-OV6-Ab), which enhance the sensitivity of the biomarker and makes the designed sensor specific for oval cells ...
