High frequency of promoter hypermethylation of RASSF1A in nasopharyngeal carcinoma.
We have investigated the genetic and epigenetic changes of a newly isolated tumor suppressor gene on 3p21.3, RASSF1A, in nasopharyngeal carcinoma (NPC). Four xenografts, four cell lines and 21 primary tumors were examined. Promoter hypermethylation of the 5'CpG island of RASSF1A was detected in 4 of 4 (100%) xenografts, in 3 of 4 (75%) cell lines, and in 14 of 21 (66.7%) primary tumors but not ...
متن کاملPromoter hypermethylation of multiple genes in nasopharyngeal carcinoma.
PURPOSE The methylation profile of nasopharyngeal carcinoma (NPC) has been investigated by a candidate gene approach. EXPERIMENTAL DESIGN Four NPC cell lines, 4 NPC xenografts, 33 NPC primary tumors, and 6 samples of normal nasopharyngeal epithelium were subjected to methylation-specific PCR for analysis of promoter methylation of eight cancer-related genes. These eight genes were RASSF1A, RA...
متن کاملPromoter hypermethylation of high-in-normal 1 gene in primary nasopharyngeal carcinoma.
PURPOSE The methylation of high-in-normal-1 (HIN-1) gene promoter in undifferentiated nasopharyngeal carcinoma (NPC) is studied. EXPERIMENTAL DESIGN The methylation status of HIN-1 in NPC cell lines, primary NPC, paired nasopharyngeal swabs, paired throat-rinsing fluid, and paired peripheral blood was assessed by methylation-specific PCR assay. The relationship between HIN-1 promoter methylat...
متن کاملGALC gene is downregulated by promoter hypermethylation in Epstein-Barr virus-associated nasopharyngeal carcinoma.
The aim of the study was to investigate the tumor-suppressor effect of GALC in Epstein-Barr virus (EBV)-associated nasopharyngeal carcinoma (NPC) and determine whether GALC was downregulated by promoter hypermethy-lation in the NPC cell line, CNE-2Z. Forty-one archival NPC biopsy specimens were compared with 15 chronic nasopharyngitis specimens. EBV-encoded RNA (EBER) was verified by in situ hy...
متن کاملHypermethylation of the p16 gene in nasopharyngeal carcinoma.
We have recently reported that inactivation of the p16 gene by mutation and deletion is common in nasopharyngeal carcinoma (NPC). The present study demonstrates that hypermethylation of the 5' CpG island can serve as an alternative mechanism for inactivation of the p16 gene in this tumor. Using Southern blotting analysis and multiplex PCR, aberrant methylation of the 5' CpG island of the p16 ge...
