ACTR3 is a tumor vascular marker (TVM) identified through expression profiling of ovarian cancer vascular cells.

Performance Comment

In PMID:21617380, 13 tumor vascular markers (TVMs) from 50 candidates identified through expression profiling of ovarian cancer vascular cells and selected to be either transmembrane or secreted, and to be either absent or expressed at low levels in normal tissues while overexpressed in tumors, based on analysis of 1,110 normal and tumor tissues from publicly available Affymetrix microarray data were investigated. ACTR3 was not selected to be studied further.
