Fig. 3. Attachment assay. The attachment ability of glioblastoma cells showed a statistically significant decrease after 6 hours (20 µM/L curcumin at 12 hours: 14.7%, p=0.001; 10 and 20 µM/L curcumin at 24 hours: 12.6% and 24.4%, p=0.001 and p<0.001). Data were presented as the mean±SD. ^*p<0.05, ^**p<0.001 compared to the control group.
