Cell Stress and Chaperones Aims and scope

Abstract

The cellular stress response (CSR) is a universal inducible reaction modulated, among others, by heat, drugs, and hormones. We aimed to investigate the role of l-thyroxine (T4) on the heat shock (HS) response in Saccharomyces cerevisiae. The CSR was evaluated by determining growth and viability of post-logarithmic phase grown yeast cultures after HS at 53 °C for 30 min. We found that long-term T4 exposure can induce a dose-dependent and Hsp90 and H+ trafficking-related thermotolerance in yeast.
