Tan IIA enhances the pro-apoptotic effect of gefitinib in HCC827/gefitinib cells. (A, B) HCC827/gefitinib cells were treated with 40 nM OXA or/and 2 μM Tan IIA for 72 hrs. Apoptotic cells were measured by flow cytometry. (C, D) Expression level of active caspase 3 in HCC827/gefitinib cells was detected with Western blotting. *P<0.05, **P<0.01 compared with control group; ##P<0.01 compared with 40 nM gefitinib group.
