Shigella Apoptosis Arrays


ABSTRACT: Array data from HeLa cells that remained Uninfected or were infected with wildtype S. flexneri serotype 2a strain 2457T. These groupings are further divided such that Uninfected or Infected cells remained untreated or were treated with the apopotosis inducer staurosporine (STS). The design of the experiment was a time course and samples were harvested at the indicated time points (hr). All hybridizations were conducted against a common reference sample. time_series_design

<h4>Background</h4>Shigella flexneri inhibits apoptosis in infected epithelial cells. In order to understand the pro-survival effects induced by the bacteria, we utilized apoptosis-specific microarrays to analyze the changes in eukaryotic gene expression in both infected and uninfected cells in the presence and absence of staurosporine, a chemical inducer of the intrinsic pathway of apoptosis. The goal of this research was to identify host factors that contribute to apoptosis inhibition in infec  ...[more]
