Multifocal accumulation of p53 protein in esophageal carcinoma: evidence for field cancerization

Autor: D, Tian, Z, Feng, N M, Hanley, R W, Setzer, J L, Mumford, D M, DeMarini

Publikováno v: International journal of cancer. 78(5)

A systematic characterization of the cancerization field of esophageal carcinoma based on p53 protein accumulation has not been reported previously. The present report presents such a study based on 50 specimens of esophageal squamous-cell carcinoma

Glutathione S-transferase-mediated induction of GC--AT transitions by halomethanes in Salmonella

Autor: D M, DeMarini, M L, Shelton, S H, Warren, T M, Ross, J Y, Shim, A M, Richard, R A, Pegram

Publikováno v: Environmental and molecular mutagenesis. 30(4)

Halomethanes are among the most common mutagenic and carcinogenic disinfection by-products present in the volatile/semivolatile fraction of chlorinated drinking water. Recent studies have demonstrated that the mutagenicity of dichloromethane (CH2Cl2)

Toxicity and mutagenicity of a mixture of 25 chemicals found in contaminated groundwater

Autor: M D, Shelby, R R, Tice, D M, DeMarini, R S, Yang

Publikováno v: IARC scientific publications. (104)

A defined mixture of 25 chemicals that are often found in contaminated groundwater was prepared as an aqueous solution and studied for mutagenicity in bacteria, for prophage induction in bacteria, for palatability and effect on weight-gain in rats an

Mycoviruses of Penicillium stoloniferum: influence of carbon–nitrogen nutrition upon replication

Autor: R. W. Detroy, P. E. Still, D. M. DeMarini

Publikováno v: Canadian Journal of Microbiology. 24:947-953

Carbon–nitrogen ratio experiments indicate that limiting nutrition not only hinders Penicillium stoloniferum host proliferation but reduces total PsV-F and PsV-S virus replication. Results of C-N experiments show a pH-induced autolysis and virus re

Transmission of PsV-F and PsV-S Mycoviruses during Conidiogenesis of Penicillium stoloniferum

Autor: C. P. Kurtzman, D. M. Demarini, D. I. Fennell, K. A. Worden, R. W. Detroy

Publikováno v: Journal of General Microbiology. 100:59-64

SUMMARY: Levels of both fast and slow Penicillium stoloniferum virus (PsV-F and PsV-S) were evaluated in single conidial isolates of P. stoloniferum NRRL5267. Approximately 7 % (3/43) of a random population of conidia from a culture of P. stoloniferu

Mutation tests in Neurospora crassa. A report of the U.S. Environmental Protection Agency Gene-Tox Program

Autor: H E, Brockman, F J, de Serres, T M, Ong, D M, DeMarini, A J, Katz, A J, Griffiths, R S, Stafford

Publikováno v: Mutation research. 133(2)

Many mutation tests have been developed in Neurospora crassa during the almost 40 years of its use in mutation research. These tests detect two major classes of mutation: gene mutation and meiotic nondisjunction. Within the first class, forward- and

Mutagenicity of skin tanning lotions

Autor: H N, Pham, D M, DeMarini, H E, Brockmann

Publikováno v: Journal of environmental pathology and toxicology. 3(1-2)

Two lotions that tan skin in the absence of sunlight and their active ingredient, dihydroxyacetone (DHA), are mutagenic in Salmonella typhimurium strain TA100 without metabolic activation. However, addition of S-9 mix that contains Aroclor 1254-induc

Mutagenicity and cytotoxicity of five antitumor ellipticines in mammalian cells and their structure-activity relationships in Salmonella

Autor: D M, DeMarini, S, Cros, C, Paoletti, P, Lecointe, A W, Hsie

Publikováno v: Cancer research. 43(8)

The mutagenicity and cytotoxicity of five antitumor compounds (ellipticines) were investigated in the Chinese hamster ovary cell hypoxanthine-guanine phosphoribosyltransferase assay and in six strains of Salmonella. All five compounds (ellipticine, 9
