Protein Synthesis & Degradation

Alternate RNA decoding results in stable and abundant proteins in mammals

Direct evidence for differential stichiometry of ribosomal proteins

The stoichiometry among ribosomal proteins (RP) correlates to the growth rate

The RP stoichiometry depends on the growth conditions

Metabolism & 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.

Increasing stress sensitivity and aerobic glycolysis during exponential growth

Parallel declines in respiration and in mitochondrial NADPH-producing enzymes

Global remodeling of metabolism during nine doublings at a constant rate

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
