TEM7 (Tumor Endothelial Marker 7, Plexin Domain Containing 1, Plexin Domain-containing Protein 1 Precursor, PLXDC1, Tumor Endothelial Marker 3, TEM3)

Recently, using SAGE (Serial Analysis of Gene Expression) technology, St. Croix et al, have identified 46 genes, whose expression is specifically elevated in tumor-associated endothelium. Nine of these genes were prominently expressed only in tumor endothelial cells (EC), but were absent or barely detectable in normal ECs, and named as Tumor Endothelial Markers (TEMs, TEM 1-9). TEM7 (Tumor endothelial marker 7) transcripts are specifically expressed in the endothelium of colorectal cancer, primary cancers of lung, pancreas, breast, and brain. TEM7 is expressed specifically in endothelium of these...
