1 However, we now report that TPA-treated and non-treated SH-SY5Y cells express PKC-alpha, but not PKC-beta and PKC-gamma, mRNA. Tetradecanoylphorbol Acetate protein kinase C alpha Homo sapiens
2 Furthermore, only a slight down-regulation of the PKC-alpha protein could be seen during prolonged treatment with 16 nM TPA, the concentration giving optimal differentiation. Tetradecanoylphorbol Acetate protein kinase C alpha Homo sapiens
3 In contrast, a higher concentration of TPA (1.6 microM) results in a poor neuronal differentiation and a complete down-regulation of PKC-alpha. Tetradecanoylphorbol Acetate protein kinase C alpha Homo sapiens
4 PKC-alpha was rapidly translocated to the particulate fraction and remained membrane bound for at least 4 days during treatment with 16 nM TPA. Tetradecanoylphorbol Acetate protein kinase C alpha Homo sapiens
