Positive and negative results have been reported by various investigators for in vivo and in vitro chromosome aberration (CAB) assays, in vivo and in vitro sister chromatid exchange (SCE) assays, and in vivo… (More)
Collaboration across research, government, academic, and private sectors is integrating more than 70 scientific computing libraries and applications through a tailorable provenance framework, empowering scientists to exchange and examine data in novel ways.
The purpose of this study was to localize the xanthine guanine phosphoribosyl transferase gene (gpt) to a specific chromosome to investigate its proposed autosomal location in the AS52 cell line. AS52 cells are hgprt-deficient Chinese hamster ovary (CHO) cells which carry a single functional copy of the E. coli gpt gene. Fluorescence in situ hybridization… (More)
A 14-day subchronic toxicity study is routinely conducted in Fischer 344 rats at the Lilly Research Laboratories. This study is done to gather preliminary toxicological information about chemical entities showing efficacy in various pharmacological screens. This manuscript describes the validation of a method for evaluating micronuclei in the bone marrow… (More)
