The epithelial surface is the principal site of staphylococcal infection. The goal of this work was to investigate the cytopathic effect of S. aureus and its ability to affect host cell cycle. Cultures of human cervix cancer HeLa and mammary gland bovine MAC-T epithelial cells were used to study in vitro the effects of S. aureus strains from human or ruminant origins. Using microscopic examination, we found that S. aureus induced an enlargement of the host cells and we observed that S. aureus slowed down cell proliferation. Similar effect was observed on both human and bovine cells using the human or the ruminant strains. Microscopic analysis of DAPI-stained cells revealed huge decrease of mitotic indexes in infected HeLa and Mac-T cells, synchronized by Double Thymidine Block. Flow cytometry analysis showed that S. aureus induces G2/M phase delay in synchronous HeLa cells. Western blot analysis revealed that the G2/M phase delay was associated with an accumulation of inactive phosphorylated cyclin-dependent kinase Cdk1/cdc2, a key inducer of mitosis entry, and dephosphorylation of core histone H3, an important component of the epigenetic landscape. Altogether, these results suggest that the delay in G2/M phase transition of the infected epithelial cells may be one of the mechanisms employed by S. aureus to survive and to propagate inside the host. Further investigations are ongoing to fully understand the mechanisms associated to this type of S. aureushost cell interactions.</description> <date>2012-11-13</date> </dc> </metadata> </record> </GetRecord> </OAI-PMH>
