Seroepidemiological studies imply a correlation between Epstein-Barr virus (EBV) reactivation and the development of nasopharyngeal carcinoma (NPC). N-nitroso compounds, phorbols, and butyrates are chemicals found in food and herb samples collected from NPC high-risk areas. These chemicals have been reported to be risk factors contributing to the development of NPC, however, the underlying mechanism is not fully understood.

Seroepidemiological studies implicate a correlation between Epstein-Barr virus (EBV) reactivation and the development of nasopharyngeal carcinoma (NPC). Moreover, N-nitroso compounds are known chemical carcinogens in preserved foodstuffs and cigarettes and have been implicated as risk factors contributing to the development of NPC. Here, NPC cell lines latently infected with EBV, NA and HA, and the corresponding EBV-negative NPC cell lines, NPC-TW01 and HONE-1, were used as the model system in this study.

Nasopharyngeal carcinoma (NPC) is an endemic malignancy prevalent in South East Asia. Epidemiological studies have associated this disease closely with Epstein-Barr virus (EBV) infection. Previous studies also showed that EBV reactivation is implicated in the progression of NPC.

Nasopharyngeal carcinoma (NPC) is closely associated with Epstein-Barr virus (EBV) infection and exposure to environmental carcinogens. In this study, an inducible Epstein-Barr virus (EBV) reactivation NPC cell line, NA, was used to investigate the impact of recurrent 12-O-tetradecanoylphorbol-13-acetate-sodium n-butyrate (TPA/SB) treatment and EBV reactivation on chromosomal abnormalities utilizing array-based comparative genomic hybridization (CGH). It was observed that most copy-number aberrations (CNA) were progressively nonrandomly clustered on chromosomes 3, 8, and 9, as the frequency of TPA/SB treatment and EBV reactivation increased.

N-nitroso compounds (NOCs) and Epstein-Barr virus (EBV) reactivation have been suggested to play a role in the development of nasopharyngeal carcinoma (NPC). Although chemicals have been shown to be a risk factor contributing to the carcinogenesis of NPC, the underlying mechanism is not fully understood. We demonstrated recently that N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) enhances the genomic instability and tumorigenicity of NPC cells via induction of EBV reactivation.
