Figure 1From: Hydroxycamptothecin induces apoptosis and inhibits tumor growth in colon cancer by the downregulation of survivin and XIAP expressionHCPT inhibits cell proliferation. Colon cancer cells were treated with 10-hydroxycamptothecin (HPCT) at the indicated dose (A) or at the indicated time (B). Cell inhibition was measured by MTT assay. The data are expressed as means ± SD from three independent experiments.Back to article page
