Activation of the Wnt/beta-catenin signaling pathway occurs in several types of cancers and thus it is an attractive target for anticancer drug development. To identify compounds that inhibit this pathway, we screened a chemical library using a cell-based beta-catenin/Tcf-responsive reporter. We identified FH535, a compound that suppresses both(More)
The ts41 mutation of Chinese hamster cells was first isolated and characterized by Hirschberg and Marcus (1982) who showed that at nonpermissive temperature, cells accumulate up to 16C equivalents of DNA. Here we show that the mutation is recessive and at nonpermissive temperature, cells replicate their genome normally, but instead of going on into G2, M,(More)
