Number of genes involved in processes of interest. After the data mining in the literature, the 183 genes of interest were classified in several categories (light blue: known to be involved in hypoxia, red: known to be involved in cancer and hypoxia, yellow: known to be involved in cancer, green: known to be involved in cancer and metastasis, dark blue: known to be involved in cancer and metastasis and hypoxia, orange: not known to be involved in cancer or metastasis or hypoxia) in function of the combination of approaches (I for intersections, UI for union intersections and MA for meta-analyses).
