To confirm these findings, we tested two additional previously published shRNAs targeting GAB2 (shGAB2 #6 and #7) or a control shRNA into FUOV1 cells and 2 additional ovarian cancer cell lines that also overexpressed GAB2 (NIH:OVCAR3 and IGROV1 cells) (Supplementary Figure 1). This evidence concerns the gene GAB2 and ovarian cancer.
