AbstractEpstein-Barr virus (EBV) has been detected in the tumor cells of several cancers, including some cases of lung carcinoma (LC). However, the genomic characteristics and diversity of EBV strains associated with LC are poorly understood. In this study, we sequenced the EBV genomes isolated from four primary LC tumor biopsy samples, designated LC1 to LC4. Comparative analysis demonstrated that LC strains were more closely related to GD1 strain. Compared to GD1 reference genome, a total of 520 variations in all, including 498 substitutions, 12 insertions and 10 deletions were found. Latent genes were found to harbor the most numbers of nonsynonymous mutations. Phylogenetic analysis showed that all LC strains were closely related to Asian EBV strains, whereas different from African/American strains. LC2 genome was distinct from the other three LC genomes, suggesting at least two parental lineages of EBV among the LC genomes may exist. All LC strains could be classified as China 1 and V-val subtype according to the amino acid sequence of LMP1 and EBNA1, respectively. In conclusion, our results showed the genomic diversity among EBV genomes isolated from LC, which might facilitate to uncover the previously unknown variations of pathogenic significance.
