title: [Alterations of p16 gene in transformed BEP2D cells induced by NNK].
abstract: Silver-staining PCR-SSCP method was used to detect the alterations of p16 gene in the transformed BEP2D cells induced by NNK. Compared with control cells, the abnormal shifting of the single-stranded DNA(ssDNA) in E1. beta but not p16 Exon 1-3 was identified in transformed BEP2D cells. The results suggested that the mutation and/or deletion in p16 gene might be one cause of NNK-unduced carcinogenesis in human bronchial epichellium.
