摘要：

To initially analyze the genomic abnormalities in human oral squamous cell carcinoma, DNA extracted from each of four oral carcinoma cell lines (Ca9-22, HO-1-u-1, HSC-2, KB) was examined using restriction landmark genomic scanning (RLGS), a method especially conducive to detection of amplifications and rearrangements of genomic DNA. Isolated cell line and normal oral epithial DNAs were sequentially cleaved with specific restriction enzymes, radiolabelled and separated in two-dimensional gel electrophoreses. Thirteen distinct fragments were commonly amplified in the oral cancer cell lines, six of which were evident in all samples. These results suggest genetic alterations characteristic of oral squamous cell carcinogenesis. (C) 1998 Elsevier Science Ltd. All rights reserved.
