MIA PaCa-2 (A, B) and HPAF-II (C, D) pancreatic cancer cells were cultured for 72h in the presence of indicated doses of embelin or ellagic acid. Proliferation was assessed by measuring 3H-thymidine incorporation into DNA. P-values are for one-sided one-sample t-tests comparing with controls (100 for A and B, 1 for C and D). With Bonferroni’s adjustment, p<0.01 are considered as significant for A and B, p<0.0125 are considered as significant for C and D.
