title: Effects of sodium butyrate and dibutyryl cyclic AMP on thermosensitivity of HeLa cells and their production of heat shock proteins.
abstract: When HeLa cells were incubated at 42 degrees C for 6 h with 1 mM sodium butyrate or when cells treated with 1 mM dibutyryl cyclic AMP for 24 h were incubated at 42 degrees C for 6 h, they were more thermoresistant than heated control cells without such drugs. The production of heat shock proteins was not enhanced by the drug treatment. These results suggest that there is a factor (or factors) other than heat shock proteins that accounts for the thermoresistance of HeLa cells.
