AB  - Background: Malignant melanoma resistance to chemotherapy remains a major limitation to treatment. Our aim was to identify genes associated with drug resistance, in order to better understand the molecular events underlying the drug-resistant phenotype. Materials and Methods: A human melanoma cell line and its drug-resistant variants obtained by selection with MNNG or 6-thioguanine were used. Alterations in gene expression were characterized by differential display reverse transcription-polymerase chain reaction (DDRT-PCR). Prominent mRNA fragments present in selected variants and not in the parental cells were identified and characterized by cloning and sequencing. Differential expression was confirmed by real-time RT-PCR. Results: Three functionally distinct transcriptional products were demonstrated: the chaperonin subunit TCP 1-zeta-6A (CCT6A), the hyaluronan receptor CD44 and LPPR-2, the lipid phosphate phosphatase-related protein type-2. Conclusion: Genes with altered expression were identified in drug-resistant variants. The identified molecules may provide new insights into the molecular basis for melanoma resistance to chemotherapy.

AB  - Destabilization of the genome seems to be an important step in the generation of drug resistance. Since malignant melanoma is extremely resistant to chemotherapy, we used human melanoma cell lines as a model to investigate the putative role of genomic instability in the appearance of drug resistance. Drug-resistant variants were obtained with MNNG, BiCNU, doxorubicin and 6-thioguanine selection of melanoma cell lines. Genomic alterations in variant cells were detected by arbitrarily primed PCR of Alu-I digested DNA (Alu-I-AP-PCR). Two differential DNA bands from 6-TG-resistant cell variants were sequenced. One is homologous to intron 25 of the neural cell adhesion molecule L1 and the second to endogenous retroviral LTR sequences. We have shown that drug-resistant melanoma cell lines accumulate genomic alterations that are efficiently detected by Alu I-AP-PCR and that drug-resistant variants show genomic instability, including variations in LTR sequences, which may be associated with the appearance of the drug resistance phenotype.
