Animal models have historically informed veterinary and human pathophysiology. Next-generation genomic sequencing and molecular analyses using analytes derived from tissue require integrative approaches to determine macroanalyte integrity as well as

We compared the lambda cII/cI transgenic mutation assay described by Jakubczak et al. [(1996): Proc Natl Acad Sci USA 93:9073-9078] to the previously established Big Blue assay. Genomic DNA isolated from liver, spleen, and lung tissue of control or e

We tested the ability of a series of known genotoxic agents to cause mutations at the hprt locus in peripheral blood T-lymphocytes of cynomolgus monkeys as measured by the ability to form clones in the presence of 6-thioguanine. Ethylmethane sulfonat

Big Blue mice harbor a recoverable transgene in a lambda/LIZ shuttle vector. In the standard assay, in vivo mutations are measured in the bacterial lacI gene using a labor-intensive color plaque assay. Applying a simpler assay [Jakubczak et al. (1996

We have been studying in vivo mutagenesis at the hypoxanthine phosphoribosyl transferase (hprt) locus in cynomolgus monkey T-lymphocytes. This primate model allows us to study mutations and their kinetics under well-controlled conditions. Previously,

We examined several experimental parameters of the lambda cI/cII transgenic mutation assay. In the assay, clear plaque lambda phage mutants are identified in a positive selection scheme following rescue of the lambda/LIZ shuttle vector from frozen ti

U-89843 is a novel pyrrolo[2,3-d]pyrimidine antioxidant with prophylactic activity in animal models of lung inflammation. During preclinical safety evaluation, U-89843 was found to give a positive response in the in vitro unscheduled DNA synthesis (U

Big Blue Rat-2 cells were evaluated for mutagenesis and mutational spectra (spontaneous and ethylnitrosourea [ENU]-induced). Survival, mutant frequency, population doubling time, and kinetics of mutant increase (to 120 hr) were determined. Exposures

The study of hprt mutations in cynomolgus monkey T-lymphocytes is part of our effort to understand the mechanisms of mutagenesis in vivo. This primate model allows us to study mutations and their kinetics at the molecular level under well-controlled

CC-1065 is a very potent antitumor antibiotic which binds in the minor groove of DNA with alkylation at N-3 of adenine. Since CC-1065 caused delayed deaths in mice at therapeutic doses, analogues were prepared whose antitumor and biochemical activiti
