UNLABELLED Undifferentiated nasopharyngeal carcinoma (NPC) has a 100% association with Epstein-Barr virus (EBV). However, only three EBV genomes isolated from NPC patients have been sequenced to date, and the role of EBV genomic variations in the pathogenesis of NPC is unclear. We sought to obtain the sequences of EBV genomes in multiple NPC biopsy(More)
Ranking as the fourth commonest cancer, esophageal squamous cell carcinoma (ESCC) represents one of the leading causes of cancer death in China. One of the main reasons for the low survival rate is that neoplasms in esophagus are not detected until they have invaded into surrounding tissues or spread throughout the body at advanced stages. A better(More)
PURPOSE Death-associated protein (DAP)-kinase gene is frequently inactivated by promoter hypermethylation in cancer. The aim of this study was to evaluate the promoter methylation status of the DAP-kinase gene in nasopharyngeal carcinoma (NPC). EXPERIMENTAL DESIGN The methylation status was evaluated by methylation-specific PCR (MSP). Thirty-two NPC(More)
Cellular senescence is a programmed cell response leading to growth arrest in human diploid fibroblasts. We have shown that a nasopharyngeal carcinoma cell line, CNE1, following treatment by the DNA-damaging agent cisplatin, can undergo cellular senescent-like growth arrest, similar to fibroblasts, judged by cellular morphological changes and the expression(More)
