From: Inhibition of ecto-ATPase activity by curcumin in hepatocellular carcinoma HepG2 cells
a Concentration-dependent inhibition by curcumin of ecto-nucleotidase activity in the presence of 1 mM ATP. The activity in the absence of curcumin was taken as 100%. n = 5. Effects of curcumin (30 μM) on the ecto-nucleotidase activity in the presence of ATP (1 mM; b), ADP (1 mM; c) or AMP (1 mM; d) in HepG2 cells. **Significantly different (p < 0.01). NS not significant (p > 0.05). n = 6 (b), n = 4 (c, d)
