1 Induction of THP-1 monocyte differentiation by phorbol 12-myristate 13-acetate (PMA) markedly increased SVCT2 mRNA, protein, and function. Tetradecanoylphorbol Acetate solute carrier family 23 member 2 Homo sapiens
2 Induction of THP-1 monocyte differentiation by phorbol 12-myristate 13-acetate (PMA) markedly increased SVCT2 mRNA, protein, and function. Tetradecanoylphorbol Acetate solute carrier family 23 member 2 Homo sapiens
3 When ascorbate was present during PMA-induced differentiation, the increase in SVCT2 protein expression was inhibited, but differentiation was enhanced. Tetradecanoylphorbol Acetate solute carrier family 23 member 2 Homo sapiens
4 PMA-induced SVCT2 protein expression was blocked by inhibitors of protein kinase C (PKC), with most of the affect due to the PKCbetaI and betaII isoforms. Tetradecanoylphorbol Acetate solute carrier family 23 member 2 Homo sapiens
5 In conclusion, PMA-induced monocyte-macrophage differentiation is enhanced by ascorbate and associated with increased expression and function of the SVCT2 protein through a pathway involving sustained activation of PKCbetaI/II, MAP kinase, NADPH oxidase, and NF-kappaB. Tetradecanoylphorbol Acetate solute carrier family 23 member 2 Homo sapiens
