title: Analysis of Epstein-Barr virus BamHI F DNA fragment in nude mouse-passaged nasopharyngeal carcinoma tissues.
abstract: Two nude mouse-passaged nasopharyngeal carcinoma (NPC) tissues, NPC-295 and NPC-306, were different in ability to transform cord blood lymphocytes and contained Epstein-Barr virus (EBV) genomes with difference in BamHI F DNA fragment. Four clones containing DNA sequences of the BamHI F fragment (54,853-62,249) were obtained from genomic libraries of NPC-295 and NPC-306 and their partial restriction enzyme maps and sequences were determined. The restriction enzyme maps of EBV DNA at the BamHI F fragment in NPC-295 and NPC-306 appeared to be similar to that of EBV B95-8 strain. However, 8 nucleotide differences were revealed between NPC-295 and the B95-8 strain when 566 nucleotides (55,405-55,970) were compared, and 15 out of 677 nucleotides analyzed (55,410-56,086) were different between NPC-306 and B95-8.
