Cordycepin, 3'
-deoxyadenosine
from Cordyceps sinensis, has been shown to exert anti-tumor effects in several cancer cell lines. This study investigated the effect of cordycepin on a rat glioma cell line. Cordycepin caused apoptosis in C6 glioma cells in a time- and concentration-dependent manner, but did not affect the survival of primary cultured rat astrocytes. Cordycepin increased the total protein levels of p53 and phosphorylated p53 in the C6 cells. Levels of cleaved
caspase-7
and poly (ADP-ribose) polymerase (PARP), but not cleaved caspase-3, were also increased after cordycepin treatment. Specific inhibitors for p53 and caspases abrogated cordycepin-induced
caspase-7
and PARP cleavage, and prevented cordycepin-induced apoptosis. Moreover, siRNA knockdown of p53 blocked cordycepin-induced cleavage of
caspase-7
and PARP. Both adenosine 2A receptor (A2AR) antagonist and small interference RNA (siRNA) knockdown of A2AR blocked cordycepin-induced apoptosis, p53 activation, and
caspase-7
and PARP cleavage. These may provide a new strategy of cordycepin for glioma therapy in the future.
