SummaryThe nuclear matrix from HeLa cells heated at 45°C was isolated to determine the effect of thermal shock on its composition and structure. The matrix from unheated cells contained about 10 per cent of total cell protein and was observed to be a spherical particle with a diameter ranging from 3 to 5 μm with the major constituent polypeptides having molecular weights of 45, 47, 55, 57, 59 and 65 kilodaltons. The nuclear-matrix protein mass increased linearly with increasing exposure time at 45°C with no observable change in its size or shape. The additional proteins were observed in general to have molecular weights greater than 45 kilodaltons, with marked increases in polypeptides of 28·5, 38·5, 60, 66, 75, 81, 88, 100 and 115 kilodaltons. An exponential relationship was observed between heat-induced cytotoxicity and the nuclear matrix protein mass increase. A 15 per cent increase in matrix protein mass was sustained prior to the onset of cytotoxicity, while a 35 per cent increase in matrix protein c...
