title: Induction of chromosome damage and sister-chromatid exchanges in human lymphocyte cultures by the antitumour antibiotic Neocarzinostatin.
abstract: Neocarzinostatin (NCS), a chemotherapeutic antibiotic, was investigated for the ability to induce chromosomal aberrations and sister-chromatid exchanges (SCEs) in human lymphocyte cultures. It was observed that the antibiotic causes a cell-cycle delay and reduces the mitotic index. Analysis of the induced chromosomal abnormalities showed that they are mainly chromosome and chromatid breaks; while the frequency of SCEs was increased, the magnitude indicates that NCS cannot be considered a potent inducer of SCEs.
