On the protein level EPCR is known to be expressed on HUVEC[26], endothelium in the heart, the lung, the kidney, the skin and on other organs[4] but also on epithelial cells such as a prostatic cancer cell line[32], human alveolar epithelium[27], rat lung[28], pancreatic tissue[29] and gastric epithelial cells[30]. The gene discussed is PROCR; the disease is prostate cancer.
