Abstract:     Disclosed are compositions and methods for inhibiting hexokinase enzymes in mammalian cells. Specifically provided are proteins that stimulate the production of trehalose-6-phosphate and their respective genes; hexokinase-specific ribozymes and genes encoding such constructs; and agents that competitively reduce hexokinase activity, e.g., by displacing hexokinase from mitochondria, and their respective genes. The latter group of agents includes inactive hexokinases and fragments thereof that retain mitochondrial binding functions and hexokinase-glucokinase chimeras that further substitute glucokinase activity for hexokinase activity. Mammalian cells including such hexokinase inhibitors, methods of making such cells and various in vitro and in vivo methods of using cells with reduced hexokinase activity are also described herein.
