Possible Involvement of Rapamycin-Sensitive Pathway in Bcl-2 Expression in Human Neuroblastoma SH-SY5Y Cells

摘要

References(15) Cited-By(2) In human neuroblastoma SH-SY5Y cells, treatment with immunosuppressants such as FK506, cyclosporin A or rapamycin for 4 days induced the enhancement of the 27-kDa Bcl-2α protein level. Among immunosuppressants, rapamycin has most potency. Treatment with herbimycin A or wortmannin also enhanced Bcl-2 expression, but the BB type of platelet-derived growth factor decreased the level. These results suggest that Bcl-2 expression is probably regulated by the cascade of tyrosine kinase, phosphatidylinositol 3-kinase and rapamycin-sensitive p70 S6-kinase in human neuroblastoma SH-SY5Y cells.
