Aerobic Glycolysis

We found that exponential growth at a constant rate can represent not a single metabolic/physiological state but a continuum of changing states and that aerobic glycolysis can reduce the energy demands associated with respiratory metabolism and stress survival.

Protein Synthesis

We found that the stoichiometry among core RPs in wild-type yeast cells and ESC depends both on the growth conditions and on the number of ribosomes bound per mRNA

The fitness of cells with a deleted RP-gene is inversely proportional to the enrichment of the corresponding RP in polysomes

Cell Growth & Division

We found that most genes annotated to the cell division cycle are expressed periodically even in nondividing cells as part of a cell growth cycle
