Hereditary PAH (HPAH) is often caused by mutations in the bone morphogenetic protein receptor type 2 gene (\n                      <jats:italic>BMPR2<\/jats:italic>\n                      ). However, the mechanisms by which these mutations cause PAH remain unclear.

One of these proteins, translationally controlled tumor protein (TCTP), was selected for further study because of its well-established role in promoting tumor cell growth and survival. Immunostaining showed marked upregulation of TCTP in lungs from patients with HPAH and idiopathic PAH, associated with remodeled vessels of complex lesions. Increased TCTP expression was also evident in the SU5416 rat model of severe and irreversible PAH, associated with intimal lesions, colocalizing with proliferating ECs and the adventitia of remodeled vessels but not in the vascular media. Furthermore, silencing of TCTP expression increased apoptosis and abrogated the hyperproliferative phenotype of blood-outgrowth ECs from patients with HPAH, raising the possibility that TCTP may be a link in the emergence of apoptosis-resistant, hyperproliferative vascular cells after EC apoptosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion\u2014<\/jats:title>\n                    <jats:p>Proteomic screening identified TCTP as a novel mediator of endothelial prosurvival and growth signaling in PAH, possibly contributing to occlusive pulmonary vascular remodeling triggered by EC apoptosis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1161\/circulationaha.114.008777","type":"journal-article","created":{"date-parts":[[2014,3,22]],"date-time":"2014-03-22T00:52:25Z","timestamp":1395449545000},"page":"2125-2135","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":72,"title":["Proteomic Analysis Implicates Translationally Controlled Tumor Protein as a Novel Mediator of Occlusive Vascular Remodeling in Pulmonary Arterial Hypertension"],"prefix":"10.1161","volume":"129","author":[{"given":"Jessie R.","family":"Lavoie","sequence":"first","affiliation":[{"name":"From the Ottawa Hospital Research Institute, Sprott Centre for Stem Cell Research and Regenerative Medicine Program, Ottawa, ON, Canada (J.R.L., C.P.-I., D.W.C., B.J., W.S.F., D.J.S.);
