Identification of an invasion and tumor-suppressing gene, Endoglin (ENG), silenced by both epigenetic inactivation and allelic loss in esophageal squamous cell carcinoma.

Endoglin (ENG) has been identified as a candidate tumor-suppressor gene in esophageal squamous cell carcinoma (ESCC). Earlier microcell-mediated chromosome transfer (MMCT) studies of chromosome 9 in ESCC narrowed down a tumor-suppressive critical region to 9q33-34. ENG maps to 9q34-qter and encodes a transformation growth factor beta (TGFbeta) superfamily auxiliary receptor.

Esophageal and gastric cardia cancers on 4238 Chinese patients residing in municipal and rural regions: a histopathological comparison during 24-year period.

Background: Nutrition deficiencies or poverty traditionally have been recognized to be related with increased risk for esophageal cancer (EC) in rural regions at junction of Henan, Hebei, and Shanxi provinces in northern China--the highest incidence area for esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinoma (GCA). Since the 1980s, economic and nutrition condition in these areas have been improved greatly. However, the histopathological types, staging pattern, and occurrence of ESCC and GCA, especially for esophageal adenocarcinoma (EAC), which have been rarely examined in the Chinese population during the past decades in these areas have not been well characterized to date.

WITHDRAWN: Loss of heterozygosity analyses of esophageal squamous cell carcinoma and precursor lesions from a high incidence area in China.

Distinct profiles of critically short telomeres are a key determinant of different chromosome aberrations in immortalized human cells: whole-genome evidence from multiple cell lines.

Chromosomal aberrations are common in cancers. However, the search for chromosomal aberrations leading to development of specific solid tumors has been severely hindered because the majority of solid tumors have complex chromosomal aberrations that differ within the same tumor types. A similar phenomenon exists in immortalized cell lines.
