Telomerase activity in esophageal carcinoma

Telomerase is a ribonucleoprotein that synthesizes telomeric DNA. Immortalized and carcinoma cells show no loss of telomere length during cell division. Telomerase activity has been demonstrated in carcinomas of various organs, but not in nonneoplastic tissues. In patients with esophageal carcinoma, no data have been reported concerning the relationship between telomerase activity and clinicopathological findings.
