Figure 8: In vitro effect of FBPase and GS antisense cDNAs expression on glycogen content of rat glioma-derived cell line. Cells were harvested at various times after medium was renewed. Value represents the mean of 7 experiments (corresponding to 3 sets of transfection) ± SEM. < 0.05, < 0.001 versus empty plasmid, and statistical analysis was made using Student test.
