Human cachexia\u2010associated protein (HCAP) was recently identified from a breast cancer library based on the available 20\u2010amino acid sequence of proteolysis\u2010inducing factor (PIF), which is a highly active cachectic factor isolated from mouse colon adenocarcinoma MAC16. Herein, we investigated the expression of HCAP in CaP and its potential involvement in CaP\u2010associated cachexia. <jats:italic>HCAP<\/jats:italic> mRNA was detected in CaP cell lines, in primary CaP tissues and in its osseous metastases. <jats:italic>In situ<\/jats:italic> hybridization showed <jats:italic>HCAP<\/jats:italic> mRNA to be localized only in the epithelial cells in CaP tissues, in the metastatic foci in bone, liver and lymph node, but not in the stromal cells or in normal prostate tissues. HCAP protein was detected in 9 of 14 CaP metastases but not in normal prostate tissues from cadaveric donors or patients with organ\u2010confined tumors. Our Western blot analysis revealed that HCAP was present in 9 of 19 urine specimens from cachectic CaP patients but not in 19 urine samples of noncachectic patients. HCAP mRNA and protein were also detected in LuCaP 35 and PC\u20103M xenografts from our cachectic animal models. Our results demonstrated that human CaP cells express HCAP and the expression of HCAP is associated with the progression of CaP and the development of CaP cachexia. \u00a9 2003 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ijc.11035","type":"journal-article","created":{"date-parts":[[2003,3,28]],"date-time":"2003-03-28T12:49:30Z","timestamp":1048855770000},"page":"123-129","source":"Crossref","is-referenced-by-count":33,"title":["Expression of the human cachexia\u2010associated protein (HCAP) in prostate cancer and in a prostate cancer animal model of cachexia"],"prefix":"10.1002","volume":"105","author":[{"given":"Zejing","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva","family":"Corey","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.
