This integration and visualization of both experimental and in silico microarray-based data illustrate the existence of mutual interconnections between four target genes such as PTPRC/CD45, ID3, APOBEC3G, ID2 and point to more separate biological function(s) of the node around ESR1 in advanced stage serous ovarian cancer. This evidence concerns the gene APOBEC3G and ovarian serous adenocarcinoma.
