Four human melanoma cell lines with different copy numbers of chromosomes 9 and 21q, as studied by the G-band technique, fluorescent in situ hybridisation (FISH) and Polymerase chain reaction (PCR), were tested for their sensitivity to Interferon-alpha (IFN-alpha) and Interferon-beta (IFN-beta) in relation to dosage of interferon genes (#9) and interferon receptor genes (#21p). The two most sensitive cell lines were those containing the highest numbers of #9 per cell, while the number of #21q copies (receptor genes) seemed to have no influence on the interferon sensitivity.
