Influence of Active and Non-active Protein C on Human Ovarian Cancer Stem Cells

Abstract Introduction: The coagulation/fibrinolysticsystem control the intravascular fibrin hemostasis;in addition to participating in a wide variety of physio-pathological processes. The components of the system have an influence on tumor growth, invasion and metastasis. This is a result of their involvement in tumor matrix construction, angiogenesis and cell migration. Several homeostatic markers are currently used to predict the advent of thrombosis. However, none of these markers directly indicate the course and progression of the disease. Destabilization of peri-tumoral matrix enhances the malignant phenotype of cancer cells. The characterization of cytokines and proteolytic enzymes, secreted in tumor microenvironment, plays an important role in the mechanism of the escape phenomenon. However, the consequence of interaction of protein C on cancer stem cells is poorly investigated. Objective: The aim of our study was to analyze the physio-pathological response of human ovarian cancer stem cells (OVCAR...
