Abstract

During the lytic infection of monkey and mouse cells with simian virus 40 and polyoma virus, respectively, the preferentially increased synthesis of two host proteins of 92,000 and 72,000 Mr was observed by 15 to 20 h after infection besides the general stimulation of most cellular proteins. The incubation of uninfected monkey and mouse cell cultures for 30 to 60 min at 43.5 degrees C induced the enhanced synthesis of at least three proteins of 92,000, 72,000 and 70,000 Mr, the last one being the major heat shock protein of mammalian cells. Two-dimensional gel electrophoresis and partial proteolytic digestion confirmed that the same 92,000- and 72,000-Mr proteins are stimulated by virus infection and thermal treatment. In simian virus 40-infected CV-1 cells, we also observed the weak stimulation of a 70,000-Mr protein comigrating in gel electrophoresis with the major heat shock protein. The 92,000-, 72,000- and 70,000-Mr proteins of monkey cells are structurally very similar to the corresponding proteins of mouse cells. In immunoprecipitations, no specific association of these proteins to simian virus 40 T antigens was noticed.
