2 12-O-tetradecanoylphorbol-13-acetate (TPA) downregulates expression of CD30 in erythroleukemia cell line K562. Tetradecanoylphorbol Acetate TNF receptor superfamily member 8 Homo sapiens
3 In this study, modulation of the CD30 molecule was investigated by the treatment with 12-O-tetradecanoyl-phorbol-13-acetate (TPA). Tetradecanoylphorbol Acetate TNF receptor superfamily member 8 Homo sapiens
4 In this study, modulation of the CD30 molecule was investigated by the treatment with 12-O-tetradecanoyl-phorbol-13-acetate (TPA). Tetradecanoylphorbol Acetate TNF receptor superfamily member 8 Homo sapiens
5 When cultures were supplemented with TPA, CD30 transcript was downregulated in a dose- and time-dependent manner in the erythroleukemia cell line K562. Tetradecanoylphorbol Acetate TNF receptor superfamily member 8 Homo sapiens
6 This consecutive reduction of both the transcript and proteins suggests that TPA directly inhibits the transcriptional step of CD30, and subsequently CD30 molecules would decrease on the cell surface. Tetradecanoylphorbol Acetate TNF receptor superfamily member 8 Homo sapiens
