Effect of amino acid analogs on the development of thermotolerance and on thermotolerant cells
Journal of Cellular Physiology, 1993AbstractExposure 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

Cytoskeletal thermotolerance in NRK cells
International Journal of Hyperthermia, 1993 We investigated the effect of heat shock on the cytoskeletons (actin stress fibres, intermediate filaments and microtubules) and the relation between thermotolerance of cytoskeletons and thermotolerance as defined by clonogenic survival in normal rat kidney (NRK) cells.

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 ...

Thermotolerance induced by 2,4-dinitrophenol
International Journal of Hyperthermia, 1987 The capacity of 2,4-dinitrophenol (DNP) to induce thermotolerance in 3-day-old larvae of Lymnaea has been investigated. Induction of thermotolerance is dependent on the DNP concentration, the duration of treatment, and on the pH of the medium. Optimal conditions for the induction of thermotolerance are 10 min, 2.5 mM DNP at pH 4.7.

HSP104 Required for Induced Thermotolerance
Science, 1990A 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, 2010AbstractBackground 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.

Investigation of Thermotolerance in Mouse Testis
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1985The 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, 1982The 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, 1982The 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.
