Temperature response in cold tolerance of C. elegans
Reaction to temperature changes must include the whole of the organism. If not, only certain tissues and organs would respond, whereas organs would be totally unprepared for the change. Equally, it is useful for an organism to store information as to which temperatures yielded the environment most conducive to growth.
C. elegans is a tiny worm (<1mm) that is an established model organism for animal studies due to the combination of its simplicity – it has 959 cells including 302 neurons – and the fact the species has many features conserved across many animals, including humans. These desirable traits are also combined with extensive knowledge of how to manipulate the genetics of C. elegans. These factors make it ideal for studying features that are considered fundamental to an animal species’ survival. Temperature sensing and tolerance is one of those key features. In order to investigate cold tolerance, Kuhara has been developing novel techniques in C. elegans, as well as taking advantage of established methods.
