Representative Western blots for P-gp in LS-180 cells treated with oleocanthal, cembratriene, γ-tocotrienol, and asiatic acid. Rifampicin is included as a positive control. Cells were treated for 48 h with increasing concentrations of the indicated compounds in the range of 2.5-25 μM. P-gp protein expression was analyzed by immunoblotting with C-219 mouse monoclonal antibody.
