E-GEOD-3636 - Growth phase dependent gene expression and motility_3 time courses
Submitted on 18 November 2005, released on 21 November 2005, last updated on 27 March 2012
The microarrays for the three time course experiments described in the publication titled "Gene expression profiling of Helicobacter pylori reveals a growth phase dependent switch in virulence gene expression". TC1 refers to the first time course investigating gene expression changes over the time course of growth while TC2 refers to the second time course. TC Motility_broth refers to the third time course described in the manuscript used to investigate the concurrent changes in motility and the expression of the genes in the flagellar regulon. Detailed description of the growth of H. pylori for these 3 time courses can be found in the Materials and Methods section of the manuscript along with the exact filtering criteria used to download the data from these arrays. Note that in all three time courses the data for each array were transformed after download such that the abundance of each gene's transcript represented by a given spot was relative to the level of that transcript at the 6 h time point. Also duplicate spots for each ORF on the microarray were averaged for analysis after transformation. Groups of assays that are related as part of a time series. Computed
