Mechanistic studies of a novel class of trisubstituted platinum(II) antitumor agents.

abstract：:The flux activities of de novo and salvage purine synthesis were compared in rat hepatoma 3924A cells in various growth phases. The initial rate assays of [14C]adenine, [14C]hypoxanthine, and [14C]guanine incorporation yielded Michaelis-Menten kinetics with Kms of 5, 7, and 7 microM, respectively. After replating plat...

Dramatic changes in the subcellular localization and function of EphA2 have also been linked with cancer, and in particular, unstable cancer cell-cell contacts prevent EphA2 from s...

abstract：:Failure of cytokinesis results in tetraploidy and can increase the genomic instability frequently observed in cancer. The peptidyl-prolyl isomerase Pin1, which is deregulated in many tumors, regulates several processes, including cell cycle progression. Here, we show a novel role for Pin1 in cytokinesis. Pin1 knockout...
