Beta-TocopHERol 对由 phorbol 12-myriSTATe 13-acetate (PMA) 诱导的人红白血病细胞 (HEL) 粘附有影响。

Beta-Tocopherol shows effect on human erythroleukemia cell (HEL) adhesion induced by phorbol 12-myristate 13-acetate (PMA).

Adhesion induced by PMA stimulation was prevented by 44.5% by physiological concentrations of alpha-tocopherol. Under the same experimental conditions, Beta-Tocopherol, an analogue of alpha-tocopherol, produced 11% inhibition of adhesion. Cell response gradually increased from 0 to 24 h of alpha-tocopherol treatment. Only a slight time dependency of Beta-Tocopherol inhibition was observed. Another human erythroleukemia cell line (K562) and the human monocyte tumor cell line U937 showed 5.0 and 11.2% inhibition, respectively. Similar to alpha-tocopherol, the protein kinase C inhibitor, Calphostin C, and the MAPK inhibitor, PD98059, prevented PMA-induced cell adhesion. An inhibition of ERK-1 phosphorylation was observed for alpha-tocopherol only in HEL, implying that MAP kinase pathway is involved in this cell line.
