Abstract

Biochemical and genetic analysis of anhydrobiosis, the viable state of suspended animation attained by certain organisms after complete desiccation, suggest that abundant, hydrophilsic proteins (hydrophilins), together with high levels of non-reducing sugars, are important for survival. The hypothesis will be tested by assessing their effect in mammalian cells, which are normally extremely sensitive to dehydration. Osmostress and drying experiments will be performed on human and mouse cells transformed with trehalose synthetic genes and or a novel hydrophilin gene identified in anhydrobiotic nematodes. Cell viability will be assayed, and the effect of genetic modifications on stress responses to hypertonicity and dehydration assessed. Fully desiccation tolerant mammalian cells will have a number of applications, and are an ultimate goal.
