Abstract:
We investigated the heat-sensitivity of normal human cells and cells derived from human cancers (cancer cells) heated at 43 degrees C under different culture conditions. Primary human cells which keep in contact with each other show heat resistance, but cancer cells do not. This does not correlate with the total cellular amount of heat shock protein 72, but rather with accumulation of the protein in the nucleus after heating.
