Abstract
A gene is regulated by introducing into a cell an inducible, tissue-specific antisense DNA construct. The antisense DNA construct comprises any inducible, tissue-specific gene, into which a DNA sequence antisense to any DNA sequence of the gene targeted for regulation has been inserted. The inducible, tissue-specific antisense DNA construct transcribes a hybrid messenger RNA containing an RNA sequence antisense to a sequence of the messenger RNA of the gene targeted for regulation. The hybrid messenger RNA also contains the RNA sequence of the inducible, tissue-specific gene. Some examples of suitable inducible genes include those selected from the group consisting of mammalian cytosolic phosphoenolpyruvate carboxykinase (PEPCK) (GTP, EC 4.1.1.32), mammalian atrial natriuretic factor (ANF), and mammalian alpha myosin heavy chain (.alpha.-MHC). In a preferred embodiment, the inducible, tissue-specific gene is the rat PEPCK gene.
