Camptothecin (CPT), an alkaloid, is an inhibitor of DNA Topoisomerase I (Topo I) with an IC50 value of 679 nM. Camptothecin (CPT) has strong antitumor activity against colorectal cancer, breast cancer, lung cancer and ovarian cancer, and modulates hypoxia-inducible factor-1α (HIF-1α) activity by altering miRNA expression patterns in human cancer cells.

| Cell lines | HCT116 |
| Preparation method | Briefly, cells were incubated with BrdUrd (24 h for normal cells, and 72 h for CPT-treated cells), fixed for 20 min in 2% glutaraldehyde in PBS at room temperature, and the cell membranes were permeabilized with acetone and methanol (1:1). The cells were then incubated for 30 min in 2 m HCl followed by a 30-min incubation in 0.1 m sodium borate (pH 8.5), washed three times in PBS, incubated for 60 min in 1% bovine serum albumin/PBS, and followed by a 45-min incubation in PBS containing 2 μg/ml mouse monoclonal antibody. |
