In the present work, anoikis resistance, resistance to chemotherapy, and pro-survival signaling of anchorage-dependent epithelial human ovarian cancer cells suspended in ascites in dependence of the conformational transmembrane activation state of the integrin alphavbeta3 were investigated. The results indicated that a fully active alphavbeta3 favors delayed anoikis and increased cisplatin resistance. Moreover, constitutively active alphavbeta3 initiated pro-survival signaling pathways, promoted EGF-R expression and activation, and increased the induction of anti-apoptotic factors.
