title: [Doxorubicin and menadione reduce cell proliferation of Saccharomyces cerevisiae by different mechanisms].
abstract: The aim of this study was to determine the impacts of doxorubicin and menadion on cell proliferation, cell distribution in accordance with the phases of the cell-cycle phase, glutathione concentration, ribonucleotide reductase expression, and Yap1 dependent redox-sensitive pathway activity using Saccharomyces cerevisiae as eukaryote cell model. Our data show that menadione induced cell cycle arrest in G1-phase, reduction of intracellular GSH, an increase in GSSG concentration, and dose-dependent increases in ribonucleotide reductase expression and the activity of Yap1 pathway. Doxorubicin induced cell cycle arrest in G1- and S-phases, increased GSH and GSSG concentrations, increased expression of ribonucleotide reductase, and modulated Yap-dependent pathway activity.
