Ovarian cancer is the most lethal gynecologic cancer, and this is largely related to its late diagnosis. High grade serous cancers often initially respond to chemotherapy, resulting in a better survival rate, compared to other ovarian carcinoma subtypes. We review recent work identifying a survival-associated gene expression profile for advanced serous ovarian cancer. Within this signature, the authors identified MAGP2, also known as microfibrillar associated protein 5 (MFAP5), as a highly significant indicator of survival and chemosensitivity. MAGP2 is a multifunctional secreted protein-important for elastic microfibril assembly and modulating endothelial cell behavior-with a newly identified role in cell survival. Through alpha(v)beta(3) integrin-mediated signaling, MAGP2 promotes tumor and endothelial cell survival and endothelial cell motility, providing a potential mechanistic link between MAGP2 and angiogenesis as well as patient survival.
