Copy number variation analysis of nasopharyngeal carcinoma cell lines

ABSTRACT: To analyze the global copy number aberrations of two nasopharyngeal carcinoma cell lines, TW01 and HONE1. Global copy number aberrations were analyzed by using high-resolution oligoarray CGH on two NPC cell lines, TW01 and HONE1. The overviews of array CGH profiles reveal high similarity between both NPC cell lines, but the degree of copy-number alterations were more severe in TW01 than in HONE1. There were 1204 and 1513 genes with copy-number gain (CNVs with aberration score > 0.5 and number of contiguous probes ≥ 3) in TW01 and HONE1, respectively. Among them, 850 were commonly amplified in both cell lines (Gain-TH). There were 3525 genes and 926 genes with copy-number loss (CNVs with aberration score < 0.5 and number of contiguous probe ≥ 3) in TW01 and HONE1, respectively. Among them, 582 were commonly deleted in both cell lines (Loss-TH). The most prominent CNVs observed including gain on 3q26.2-q26.31, loss on 3p21.2-q12.1, 9p24.3-p21.3, and nearly the whole Y chromosome. Overall design: Comparison experiment, genome of NPC cells vs. normal male genome (NM). Biological replicates: TW01-1 vs. NM; TW01-2 vs. NM; HONE1-1 vs. NM; HONE1-2 vs. NM.

This study aimed to assess independent effects of EBV and cigarette smoking on nasopharyngeal carcinoma, which have never been assessed in long-term follow-up studies. A cohort of 9,622 men was enrolled from 1984 to 1986. Blood samples collected at study entry were tested for antibodies against EBV antigens (anti-EBV) viral capsid antigen immunoglobulin A and DNase. The cigarette smoking habit was inquired through questionnaire interview. Newly developed nasopharyngeal carcinoma cases were ascer  ...[more]
