title: 2', 5' oligo (A) synthetase levels in interferon-sensitive or resistant breast cancer cells.
abstract: The levels of 2', 5' oligo (A) synthetase increase 15-fold when T47D cells are treated with human interferon or with interferon inducers. The results also show that interferon-treated T47D cells contain high levels of 2', 5' oligo (A) synthetase which upon incubation with ATP produces adenine oligonucleotides which are predominantly trimers. In contrast, MCF-7 and BT20 cells whether treated with interferon or not exhibit low 2', 5' oligo (A) synthetase activity.
