Glycolytic oscillations in eukaryotic cells followed by NADH imaging
Monitoring intrinsic energy metabolism over long periods of time allows the study of cellular communication between cell populations. By using the metabolite NADH as an intrinsic marker for glycolysis, the dynamics of individual cells can be monitored and their interactions studied. Glucose consumption by glycolysis and alcoholic fermentation leads to the production of metabolites, some of which are released. Coupling between yeast cells depends on the release and sensing of the messenger acetaldehyde, which diffuses through the extracellular medium. Yeast cells are well known for the oscillatory behavior of the glycolysis and their metabolic organization. The exchange of messenger molecules can result in waves and synchronized patterns in which all cells oscillate in concert. Essential to this study is an ultrasensitive detection system that allows excitation of the weak fluorescence of NADH by low-intensity UV light.
