Deregulated Gab2 phosphorylation mediates aberrant AKT and STAT3 signaling upon PIK3R1 loss in ovarian cancer

Abstract

Loss of PIK3R1 in ovarian cancer is a common event, which provides opportunities for therapeutic intervention. Here, the authors show that the STAT3 and AKT signaling pathways are activated upon PIK3R1 loss and that, in mice, inhibitors of these pathways could block tumorigenesis.
