1 The phorbol ester 12-O-tetradecanoyl-acetate (TPA) induced prominent and transient changes in the organization of the cytoskeleton in cultured amoeboid microglial cells including redistribution of actin toward the center of the cells and in the subplasmalemmal region, appearance of fine actin filaments, retraction of microtubules (MT), and rearrangement of intermediate filaments (IF) containing vimentin. Tetradecanoylphorbol Acetate vimentin Homo sapiens
2 Using this antibody, rearrangement of IF involving vimentin phosphorylation was detected within 15 to 60 min of treatment with 50 nM TPA and consisted in the appearance of intense perinuclear fluorescent label. Tetradecanoylphorbol Acetate vimentin Homo sapiens
3 Immunochemical analysis of nonionic detergent-soluble and -insoluble extracts from untreated and TPA-treated cells revealed no differences in vimentin solubility suggesting that TPA induced vimentin phosphorylation does not result in notable vimentin filament disassembly. Tetradecanoylphorbol Acetate vimentin Homo sapiens
4 Immunochemical analysis of nonionic detergent-soluble and -insoluble extracts from untreated and TPA-treated cells revealed no differences in vimentin solubility suggesting that TPA induced vimentin phosphorylation does not result in notable vimentin filament disassembly. Tetradecanoylphorbol Acetate vimentin Homo sapiens
5 Immunochemical analysis of nonionic detergent-soluble and -insoluble extracts from untreated and TPA-treated cells revealed no differences in vimentin solubility suggesting that TPA induced vimentin phosphorylation does not result in notable vimentin filament disassembly. Tetradecanoylphorbol Acetate vimentin Homo sapiens
6 Immunochemical analysis of nonionic detergent-soluble and -insoluble extracts from untreated and TPA-treated cells revealed no differences in vimentin solubility suggesting that TPA induced vimentin phosphorylation does not result in notable vimentin filament disassembly. Tetradecanoylphorbol Acetate vimentin Homo sapiens
7 However the extent of vimentin degradation was more prominent in TPA-treated cultures indicating a higher sensitivity of vimentin to proteolytic degradation. Tetradecanoylphorbol Acetate vimentin Homo sapiens
8 However the extent of vimentin degradation was more prominent in TPA-treated cultures indicating a higher sensitivity of vimentin to proteolytic degradation. Tetradecanoylphorbol Acetate vimentin Homo sapiens
