Figure 3. Triptonide does not block β-catenin nuclear translocation.
Human colon carcinoma RKO cells were treated with DMSO, 2 μM BIO and a combination of 2 μM BIO with 5 nM triptonide respectively. After 24-hour incubation, the cells were immunostained for β-catenin (green) and counterstained with DAPI (blue).
