// The nutrition and the growth rate of a cell are two interacting factors with pervasive physiological effects. Our experiments decouple these factors and demonstrate the role of a growth rate signal, independent of the actual rate of biomass increase, on gene regulation, the cell division cycle, and the switch to a respiro-fermentative metabolism.

// We find that transitions between the two phases of the cell growth cycle can account for the environmental stress response, the growth-rate response, and the cross protection between slow growth and various types of stress factors. We suggest that this mechanism is conserved across budding and fission yeast, and normal human cells.

Research interests

I am interested in the dynamics of cell growth, metabolic and regulatory processes during the eukaryotic cell division cycle (CDC), across a wide range of CDC periods. In particular, I study how the growth rate signal - which is function of the availability of nutrients and growth factors - regulates the switch between respiration and fermentation and changes the duration of phases of the cell growth and division cycles.

    The nutrition and the growth rate of a cell are two interacting factors with pervasive physiological effects. Our experiments decouple these factors and demonstrate the role of a growth rate signal, independent of the actual rate of biomass increase, on gene regulation, the cell division cycle, and the switch to a respiro-fermentative metabolism.

    We find that transitions between the two phases of the cell growth cycle can account for the environmental stress response, the growth-rate response, and the cross protection between slow growth and various types of stress factors. We suggest that this mechanism is conserved across budding and fission yeast, and normal human cells.

    We discovered that the relative durations of the phases of the yeast metabolic cycle change with the growth rate. These changes can explain mechanistically the transcriptional growth-rate responses of all yeast genes (25% of the genome) that we find to be the same across all studied nutrient limitations in either ethanol or glucose carbon source.
