Identification of a recurrent transforming UBR5-ZNF423 fusion gene in EBV-associated nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) is a distinct type of head and neck cancer which is prevalent in southern China, south-east Asia and northern Africa. The development and stepwise progression of NPC involves accumulation of multiple gross genetic changes during the clonal expansion of Epstein-Barr virus (EBV)-infected nasopharyngeal epithelial cell population. Here, using paired-end whole-transcriptome sequencing, we discovered a number of chimeric fusion transcripts in a panel of EBV-positive tumour lines.

Identification of a novel 12p13.3 amplicon in nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) is a distinct type of head and neck cancer commonly occurring in southern China. To decipher the molecular basis of this cancer, we performed high-resolution array CGH analysis on eight tumour lines and 10 primary tumours to identify the genes involved in NPC tumorigenesis. In this study, multiple regions of gain were consistently found at 1q21-q24, 7q11-12, 7q21-22.
