title: Quantitative changes of tropomyosin synthesis in RSV-transformed mammalian cells in comparison with normal fibroblasts.
abstract: Protein profiles of three tumor mammalian cell lines and three control cell lines were analyzed by two-dimensional gel electrophoresis. Comparison of the cells labeled metabolically with 35S-methionine has revealed obvious differences in an area of molecular weights 34 000--36 000 daltons and pH 4.5-5.0. Two spots have been proposed to be alpha- and beta-tropomyosin subunits. Their synthesis decreases after cell transformation.
