Figure 3From: Meta-analysis of archived DNA microarrays identifies genes regulated by hypoxia and involved in a metastatic phenotype in cancer cells Summary of the methodology. The 22 datasets (or sub-datasets) were used to build several combinations in order to run intersections, union intersections and meta-analyses. These three approaches provided 704, 269 and 406 genes respectively. A Venn's diagram was then generated using this data.Back to article page
