CDK2 is highly expressed in colon cancer cells and curcumin selectively suppresses HCT116 cell proliferation. CDK2 is highly expressed in colon cancer cells and curcumin selectively suppresses HCT116 cell proliferation. A, the CDK2 expression level is much higher in colon cancer cells (HCT116, HCT15, and DLD-1) compared with “normal” (see footnote on the first page) colon cells (HCEC). Cells were harvested and CDK2 expression was visualized using a specific antibody. Curcumin reduces proliferation of HCT116 (B), HCT15 (C), and DLD-1 (D) colon cancer cells. Each colon cancer cell line was seeded (1 × 103 cells/well) in 96-well plates and then cells were treated with curcumin (0, 5, 10, 20, or 40 μmol/L) at 6 hours after seeding. Cell growth was determined at 1, 2, or 3 days using the MTS assay as described in Materials and Methods. Data are represented as the mean ± SD as determined from three independent experiments. The asterisk (*) indicates a significant (P < 0.001) decrease in activity compared with untreated control. Tae-Gyu Lim et al.
