Effect of amino acid analogs on the development of thermotolerance and on thermotolerant cells

Journal of Cellular Physiology, 1993
AbstractExposure of HA‐1 Chinese hamster fibroblasts to amino acid analogs has been shown to have a heat‐sensitizing effect as well as inducing the heat shock response (Li and Laszlo, 1985a). In this study, we have examined the effect of amino acid analogs on the development of thermotolerance after a brief heat shock or exposure to sodium arsenite and

Physiological and biochemical characterization of intergeneric hybrids of thermotolerant and non‐thermotolerant yeasts

Journal of Basic Microbiology, 1997
AbstractKluyveromyces‐like intergeneric hybrids of thermotolerant Kluyveromyces marxianus and non‐thermotolerant Saccharomyces cerevisiae, produced in a previous study by protoplasmic fusion, have been characterized. On molasses, these strains produced ethanol in excess of 6% (v/v) both at 30 and 45 °C as against 3% and 4.2% (v/v) by the former parent ...

HSP104 Required for Induced Thermotolerance

Science, 1990
A heat shock protein gene, HSP104 , was isolated from Saccharomyces cerevisiae and a deletion mutation was introduced into yeast cells. Mutant cells grew at the same rate as wild-type cells and died at the same rate when exposed directly to high temperatures.

Microarray analysis of cellular thermotolerance

Lasers in Surgery and Medicine, 2010
AbstractBackground and ObjectivesPreviously, we have shown that a 43°C pretreatment can provide thermotolerance to a following, more severe, thermal stress at 45°C. Using cells that lack the Hsp70 gene, we have also shown that there is still some thermotolerance in the absence of HSP70 protein.

Role of HSP70 in cellular thermotolerance

Lasers in Surgery and Medicine, 2008
AbstractBackground and ObjectiveThermal pretreatment has been shown to condition tissue to a more severe secondary heat stress. In this research we examined the particular contribution of heat shock protein 70 (HSP70) in thermal preconditioning.Study Design/Materials and MethodsFor optimization of preshock exposures, a bioluminescent Hsp70‐luciferase ...

Investigation of Thermotolerance in Mouse Testis

International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1985
The effect of a two-fraction heat treatment on mouse testis has been assessed by measuring testis weight loss at 1 week after treatment. The rate of repair of 'sublethal' heat damage following the first treatment was dependent on the severity of the treatment.

Influence of Hypoxia on the Development of Thermotolerance

Radiation Research, 1982
The effect of hypoxia on the lethal response of cells exposed to single or fractionated heat treatments was examined. Chinese hamster ovary cells were exposed to graded 43/sup 0/C heat treatments in medium equilibrated with air or nitrogen (25-40 ppm O/sub 2/) plus 5% CO/sub 2/ at pH 7.25-7.4. Hypoxia was induced approx.

The Kinetics of Thermotolerance in the Mouse Foot

Radiation Research, 1982
The kinetics of thermotolerance, which is defined as the transient resistance to hyperthermia following an initial heat treatment, was studied in a normal tissue system of C3Hf/Sed mice. Hyperthermia was given by immersing animal feet in a water bath at 45.5 ± 0.1°C.

Thermotolerant yeasts and their biotechnological applications

Trends in Biotechnology
Most known yeasts are mesophilic organisms, with optimal growth at 28-30°C. However, a few species, notably Ogataea polymorpha and Kluyveromyces marxianus, can grow at temperatures around 50°C. Their thermotolerance is of both fundamental and applied interest, offering advantages for high-temperature bioprocesses.
