1 In this study we found that most of the vimentin of undifferentiated HL60 and cells induced to differentiate either along the monocytoid pathway by 12-O-tetradecanoylphorbol-13-acetate (TPA) or along the granulocytic pathway by retinoic acid was soluble in a buffer containing 1% Triton X-100/0.6 mol/l KCl in which the intermediate filament proteins usually are not soluble. Tetradecanoylphorbol Acetate vimentin Homo sapiens
2 In this study we found that most of the vimentin of undifferentiated HL60 and cells induced to differentiate either along the monocytoid pathway by 12-O-tetradecanoylphorbol-13-acetate (TPA) or along the granulocytic pathway by retinoic acid was soluble in a buffer containing 1% Triton X-100/0.6 mol/l KCl in which the intermediate filament proteins usually are not soluble. Tetradecanoylphorbol Acetate vimentin Homo sapiens
3 The distribution of both forms of vimentin changed during induction of differentiation by TPA and after 24 h the Mr 54,000 species was predominant. Tetradecanoylphorbol Acetate vimentin Homo sapiens
4 After an additional 24 h exposure to TPA the relative levels of the two forms of vimentin approached equivalence and a high level of vimentin degradation products was seen. Tetradecanoylphorbol Acetate vimentin Homo sapiens
5 After an additional 24 h exposure to TPA the relative levels of the two forms of vimentin approached equivalence and a high level of vimentin degradation products was seen. Tetradecanoylphorbol Acetate vimentin Homo sapiens
6 These results suggest that TPA may increase vimentin degradation along a pathway that has a Mr 54,000 intermediate. Tetradecanoylphorbol Acetate vimentin Homo sapiens
