1 Induction of vimentin synthesis in a murine myeloma cell line by TPA is strongly dependent on the composition of the cell culture medium. Tetradecanoylphorbol Acetate vimentin Mus musculus
2 MPC-11 mouse plasmacytoma cells virtually lacking intermediate filament (IF) proteins can be induced to synthesize and accumulate the IF protein vimentin by treatment with the tumor promoting phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA). Tetradecanoylphorbol Acetate vimentin Mus musculus
3 MPC-11 mouse plasmacytoma cells virtually lacking intermediate filament (IF) proteins can be induced to synthesize and accumulate the IF protein vimentin by treatment with the tumor promoting phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA). Tetradecanoylphorbol Acetate vimentin Mus musculus
4 Vimentin synthesis could be elicited by a TPA concentration as low as 10(-9) M in cells grown in HB-102 serum-free medium. Tetradecanoylphorbol Acetate vimentin Mus musculus
5 After 50 generations of culture in the presence of FCS, induction of vimentin synthesis was barely detectable even at a TPA concentration of 10(-6) M. Addition of FCS to cells grown in serum-free medium partially suppressed vimentin induction by TPA. Tetradecanoylphorbol Acetate vimentin Mus musculus
6 After 50 generations of culture in the presence of FCS, induction of vimentin synthesis was barely detectable even at a TPA concentration of 10(-6) M. Addition of FCS to cells grown in serum-free medium partially suppressed vimentin induction by TPA. Tetradecanoylphorbol Acetate vimentin Mus musculus
7 After 50 generations of culture in the presence of FCS, induction of vimentin synthesis was barely detectable even at a TPA concentration of 10(-6) M. Addition of FCS to cells grown in serum-free medium partially suppressed vimentin induction by TPA. Tetradecanoylphorbol Acetate vimentin Mus musculus
8 This suppression seems to be due, at least in part, to nondialyzable, heat-sensitive components of FCS, since the dialyzable fraction even enhanced vimentin induction by TPA. Tetradecanoylphorbol Acetate vimentin Mus musculus
9 When cells grown in the presence of FCS were transferred back to serum-free medium, their ability to synthesize vimentin in response to TPA treatment was readily restored. Tetradecanoylphorbol Acetate vimentin Mus musculus
10 The individual components of serum-free medium which proved to support vimentin induction by TPA were insulin and the unsaturated fatty acids oleic acid and linoleic acid. Tetradecanoylphorbol Acetate vimentin Mus musculus
