Abstract: A gene profiling signature is disclosed herein. The gene signature can predict whether a subject with ovarian cancer will be chemorefractory, chemoresistant or chemosensitive. Thus, methods are disclosed for determining whether a subject with ovarian cancer is sensitive to treatment with a chemotherapeutic agent. Methods are also provided for increasing sensitivity to the chemotherapeutic agent if the presence of differential expression indicates that the ovarian cancer has a decreased sensitivity to chemotherapeutic agent.

Abstract: A gene profiling signature for predicting ovarian cancer patient survival is disclosed herein. The gene signature can be used to diagnosis or prognosis ovarian cancer, identify agents to treat an ovarian tumor, to predict the metastatic potential of an ovarian tumor and to determine the effectiveness of ovarian tumor treatments. Thus, methods are provided for diagnosing and prognosing an ovarian tumor, such as ovarian cancer, in a subject. Methods are also provided for identifying agents that can be used to treat an ovarian tumor, for determining the effectiveness of an ovarian tumor treatment, or to predict the metastatic potential of an ovarian tumor. Methods of treatment are also disclosed which include administering a composition that includes a specific binding agent that specifically binds to one of the disclosed ovarian survival factor-associated molecules and ovarian tumor in the subject.

Abstract: The present invention is directed to diagnostic methods based upon the expression of the protein prostasin. In particular, it is concerned with assays performed on women to determine their risk of ovarian cancer.

Abstract: The present invention is directed to diagnostic methods based upon the expression of the protein osteopontin. In particular, it is concerned with assays of urine samples collected from women for the purpose of determining whether they are at increased risk for having ovarian cancer.
