Abstract |
Cordyceps extract has been reported to have various pharmacological
activities including an anti-cancer effect. We
investigated the inhibitory effect of Cordyceps militaris on
hepatitis C virus-infected human hepatocarcinoma 7.5 cells
(J6/JFH1-huh 7.5 cells). The huh7.5 cells with or without
HCV infection were treated with various concentrations of
ethanol extract of Cordyceps militaris (CME) for 48 h and the
cytotoxicity was measured by CCK-8 assay. Both J6/JFH1-
huh7.5 cells and huh7.5 cells were highly susceptible to CME.
To examine the molecular mechanisms of the inhibitory effect
on huh7.5 cells, the effect of CME on cell apoptosis was
measured using flow cytometry and the expressions of p53,
Bim, Bax, PARP, (cleaved) caspase-9, and (cleaved) caspase-
3 in huh 7.5 cells were detected by western blot assays. CME
significantly increased early apoptosis and up-regulated the
expression of Bim, Bax, cleaved PARP, cleaved caspase 9
and cleaved caspase-3. We also found the decrease of HCV
Core or NS3 protein by CME in HCV-infected huh 7.5 cells. |
