Caspase 10 mRNA expression was significantly lower in hydatidiform mole (p \u200a=\u200a 0.035) and chorioarcinoma (p \u200a=\u200a 0.002) compared with normal placenta. The caspase 8 and 10 proteins were expressed predominantly in the cytotrophoblast and syncytiotrophoblast, respectively, with significantly lower expression in choriocarcinomas than other trophoblastic tissues (p &lt; 0.05). Immunoreactivity for both caspase 8 and 10 correlated with the apoptotic index previously assessed by terminal deoxynucleotidyl transferase mediated dUTP nick end labelling (p \u200a=\u200a 0.02 and p \u200a=\u200a 0.04, respectively) and M30 (p &lt; 0.001 and p \u200a=\u200a 0.003, respectively) approaches.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    These results suggest that the downregulation of capases 8 and 10 might contribute to the pathogenesis of choriocarcinoma.\n                  <\/jats:p>","DOI":"10.1136\/jcp.2005.028027","type":"journal-article","created":{"date-parts":[[2006,1,27]],"date-time":"2006-01-27T15:12:55Z","timestamp":1138374775000},"page":"179-183","source":"Crossref","is-referenced-by-count":34,"title":["Caspase activity is downregulated in choriocarcinoma: a cDNA array differential expression study"],"prefix":"10.1136","volume":"59","author":[{"given":"P-Y","family":"Fong","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W-C","family":"Xue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H Y S","family":"Ngan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P-M","family":"Chiu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K Y K","family":"Chan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S W","family":"Tsao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A N Y","family":"Cheung","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2006,1,27]]},"reference":[{"key":"2025120618054647000_59.2.179.1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1296-457"},{"key":"2025120618054647000_59.2.179.2","first-page":"1025","volume":"12","year":"1999","journal-title":"Mod Pathol"},{"key":"2025120618054647000_59.2.179.3","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.46.3.204"},{"key":"2025120618054647000_59.2.179.4","doi-asserted-by":"crossref","first-page":"159","DOI":"10.1136\/jcp.51.2.159","volume":"51","year":"1998","journal-title":"J Clin Pathol"},{"key":"2025120618054647000_59.2.179.5","doi-asserted-by":"publisher","DOI":"10.1046\/j.1525-1438.1999.09904.x"},{"key":"2025120618054647000_59.2.179.6","doi-asserted-by":"crossref","first-page":"588","DOI":"10.1136\/jcp.52.8.588","volume":"52","year":"1999","journal-title":"J Clin Pathol"},{"key":"2025120618054647000_59.2.179.7","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.2001.01065.x"},{"key":"2025120618054647000_59.2.179.8","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.20767"},{"key":"2025120618054647000_59.2.179.9","doi-asserted-by":"publisher","DOI":"10.1067\/mob.2000.108077"},{"key":"2025120618054647000_59.2.179.10","unstructured":"Shih IM, Mazur MT, Kurman RJ.
