Thermotolerance may be due to the stabilization of thermolabile proteins that would ordinarily denature during heat shock, either by HSPs or some other factors. We show by differential scanning calorimetry (DSC) that mild heat shock irreversibly denatures a small fraction of Chinese hamster lung V79\u2010WNRE cell protein (i. e., the enthalpy change, which is proportional to denaturation, on scanning to 45\u00b0C at 1\u00b0C\/min is approximately 2.3% of the total calorimetric enthalpy). Thermostability, defined by the extent of denaturation during heat shock and determined from DSC scans of whole cells, increases as the V79 cells become thermotolerant. Cellular stabilization appears to be due to an increase in the denaturation temperature of the most thermolabile proteins; there is no increase in the denaturation temperatures of the most thermally resistant proteins, i. e., those denaturing above 65\u00b0C. Cellular stabilization is also observed in the presence of glycerol, which is known to increase resistance to heat shock and to stabilize proteins in vitro. A model is presented, based on a direct relationship between the extent of hyperthermic killing and the denaturation or inactivation of a critical target that defines the rate\u2010limiting step in killing, which predicts a transition temperature (T<jats:sub>m<\/jats:sub>) of the critical target for control V79\u2010WNRE cells of 46.0\u00b0C and a T<jats:sub>m<\/jats:sub> of 47.3\u00b0C for thermotolerant cells. This shift of 1.3\u00b0C is consistent with the degree of stabilization detected by DSC.<\/jats:p>","DOI":"10.1002\/jcp.1041420324","type":"journal-article","created":{"date-parts":[[2005,2,26]],"date-time":"2005-02-26T09:56:21Z","timestamp":1109411781000},"page":"628-634","source":"Crossref","is-referenced-by-count":52,"title":["Increased thermostability of thermotolerant CHL V79 cells as determined by differential scanning calorimetry"],"prefix":"10.1002","volume":"142","author":[{"given":"James R.","family":"Lepock","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harold E.","family":"Frey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miriam P.","family":"Heynen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Nishio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brenda","family":"Waters","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth P.","family":"Ritchie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jack","family":"Kruuv","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,2,4]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-66541-7"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.3083508"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0092-8674(79)90150-8"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/336254a0"},{"key":"e_1_2_1_6_1","doi-asserted-by":"crossref","unstructured":"Borrelli M.
