Abstract:
:Although a Chinese hamster V79 cell-based assay for inhibitors of metabolic cooperation is currently available, the development of a human cell-based assay is desirable in order to avoid inappropriate extrapolation from animal cells to human cells. Cells derived from a human teratocarcinoma cell line (designated PA-1), which has a stable pseudodiploid karyotype and excellent in vitro growth properties, were used in a metabolic cooperation assay. The assay was based on the metabolic isolation of hypoxanthine-guanine phosphoribosyltransferase (HGPRT)-deficient variants in the presence of HGPRT-proficient cells and 6-thioguanine. Chemicals which inhibit the transfer of the lethal metabolite of 6-thioguanine from HGPRT-proficient to HGPRT-deficient cells will allow for recovery of the 6-thioguanine-resistant (HGPRT-deficient) cells. Chemicals tested included 12-O-tetradecanoylphorbol-13-acetate and related analogues phorbol-12,13-didecanoate, mezerein, and 4-phorbol-12,13-didecanoate. Concurring with results previously obtained in V79 cells, 12-O-tetradecanoylphorbol-13-acetate and phorbol-12,13-didecanoate strongly inhibited metabolic cooperation, whereas mezerein was moderately inhibitory and 4 alpha-phorbol-12,13-didecanoate was inactive. These cells thus hold promise as a human cell-based assay for inhibitors of metabolic cooperation.
