Changes of cell cycle distribution by etoposide. Astrocytes were exposed to 200 mM SIN-1 and/or glucose deprivation with or without pre-(16 h) and co-treatment, or just co-treatment of etoposide
N=7. *p<0.05, **p<0.001, compared with the group simultaneously treated with SIN-1 and GD in the absence of etoposide.
