Abstract

Summary

Rat cell lines were established in which the bacterial chloramphenicol acetyltransferase (CAT) gene under control of the human immunodeficiency virus (HIV) long terminal repeat (LTR) was stably integrated. The cell lines showed a repressed phenotype for CAT expression, but could be induced for it by inhibition of protein synthesis, as well as by heat-shock and chemical inducers of the cellular stress response, such as sodium arsenite, 8-hydroxyquinoline and the heavy metals cadmium and copper. A decameric sequence present in the NF-kB binding sites in the HIV LTR (GGGACTTTCC) resembles the cellular heat-shock core sequence and may therefore be involved in the heat-shock response.
