Cordyceps militaris and mycelial fermentation induced apoptosis and autophagy of human glioblastoma cells.

ABSTRACT: This study is the first report that investigated the apoptosis-inducing effects of Cordyceps militaris (CM) and its mycelial fermentation in human glioblastoma cells. Both fractions arrested the GBM8401 cells in the G0/G1 phase, whereas the U-87MG cells were arrested at the G2/M transitional stage. Western blot data suggested that upregulation of p53 and p21 might be involved in the disruption of cell cycle progression. Induction of chromosomal condensation and the appearance of a sub-G1 hypodipoid population further supported the proapoptogenicity, possibly through the activation of caspase-3 and caspase-8, and the downregulation of antiapoptotic Bcl-2 and the upregulation of proapoptotic Bax protein expression. Downregulation of mammalian target of rapamycin and upregulation of Atg5 and
