Assessment of environmental contamination associated with a mammalian cell transformation assay

Autor: W. B. Lebherz, A. M. Losikoff, J. A. Poiley, E. B. Sansone

Publikováno v: In Vitro. 17:811-815

To estimate worker exposures to, and environmental contamination from, test chemicals and organic solvents used in an in vitro assay to assess the carcinogenic potential of chemicals, sodium fluorescein, a noncarcinogenic fluorescent material, was di

Effect of fetal bovine serum on 3-methylcholanthrene-induced transformation of hamster cells in vitro

Autor: R. J. Pienta, J. A. Poiley, R. F. Schuman, W. B. Lebherz

Publikováno v: In Vitro. 15:730-735

Eighteen lots of fetal bovine serum were tested for their ability to support clonal growth and 3-methylcholanthrene-induced morphological transformation of hamster embryo cells in vitro. Most of them supported cloning efficiencies of over 11%. Howeve

Fecal steroid 21-dehydroxylase, a potential marker for colorectal cancer

Autor: V D, Bokkenheuser, J, Winter, A C, Mosenthal, E H, Mosbach, C K, McSherry, N K, Ayengar, A W, Andrews, W B, Lebherz, R J, Pienta, S, Wallenstein

Publikováno v: The American journal of gastroenterology. 78(8)

Eubacterium lentum and phenotypically similar organisms synthesize a steroid 21-dehydroxylase which converts biliary tetrahydrodeoxycorticosterone to pregnanolone. Tetrahydrodeoxycorticosterone, in contrast to pregnanolone, is carcinogenic for hamste
