Phase: Two
QA State: Under Review


No specific ovarian data available, however EPSTI1 has been found to be highly expressed in breast cancer.

Performance Comment

EPSTI1 was one of 50 tumor vasculature-associated genes with transmembrane or secreted protein products identified through expression profiling of ovarian cancer vascular cells. These 50 tumor vascular markers (TVMs) also had low or no expression in normal tissues. EPSTI1 was not in the group of 13 selected for further validation.
