Trehalose accumulation and radiation resistance due to prior heat stress in Saccharomyces cerevisiae
In this study, we examined the accumulation of trehalose, a stress-responsive substance, upon gamma-ray irradiation by evaluating the cause of trehalose accumulation and the development of gamma-ray resistance through intracellular trehalose accumulation. Saccharomyces cerevisiae cells cultured to t...

description | In this study, we examined the accumulation of trehalose, a stress-responsive substance, upon gamma-ray irradiation by evaluating the cause of trehalose accumulation and the development of gamma-ray resistance through intracellular trehalose accumulation.
Saccharomyces cerevisiae
cells cultured to the logarithmic growth phase were irradiated with gamma rays, and the intracellular trehalose content was measured. However, trehalose was not detectable. The yeast cells with trehalose accumulation caused by pre-treatment at 40 °C were irradiated with gamma rays, and the resistance of these cells to gamma radiation was compared with that of cells without heat treatment. Trehalose accumulation resulted in gamma-ray resistance and suppressed the increase in reactive oxygen species, lipid peroxidation, and DNA double-strand break production in yeast cells. The tests were also performed with a trehalose-6-phosphate-synthase (TPS1)-deficient mutant strain (Δ
tps1
) unable to synthesize trehalose, and the results revealed that
TPS1
was involved in protection against oxidative stress. |
