The effect of hypericin, an antiviral drug and a potent protein kinase C (PKC) inhibitor, on glioma cell invasion was investigated in vitro. Treatment of the established human glioblastoma cell line, T98G, with 1 μM hypericin for 24 h resulted in a significant inhibition of the cell invasion through an artificial basement membrane, but not cell attachment or proliferation. Furthermore, tamoxifen...
The effect of hypericin, an antiviral agent and inhibitor of protein kinase C (PKC), on cell proliferation and programmed death was investigated in the human neuroblastoma cell line SK-N-SH. Hypericin induced significant growth inhibition in a dose-dependent manner demonstrated by a microculture tetrazolium (MTT) assay. DNA isolated from cells treated with hypericin at concentrations over 1 μM exhibited...
