Abstract:
:Human topoisomerase II enzymes are targets for a number of widely used anticancer agents. We have analysed a lung adenocarcinoma cell line CALU3, which has co-amplified topoisomerase II alpha and ERBB2 sequences, for the structure of the amplicon and for expression of both topoisomerase II alpha and beta. The region of chromosome 17q amplified in CALU3 also includes the retinoic acid receptor alpha locus and is therefore similar to the amplicon observed in breast cancers carrying amplified topoisomerase II alpha and retinoic acid receptor sequences. The use of fluorescence in situ hybridisation localises the amplified topoisomerase II alpha sequences to a cluster on one chromosome with single copies localised to others. CALU3 express high levels of topoisomerase II alpha is determined by Western blot, immunofluorescence and enzyme activity. The enzyme activity extracted from CALU3 is sensitive to inhibition by the topoisomerase II poison etoposide. Topoisomerase II beta expression was observed in three lung cancer cell lines including CALU3 and was confined to the nucleoli. Thus, the CALU3 cell line is an ideal model to study the amplification and expression of topoisomerase II alpha in adenocarcinomas.
