Bcl-2/Bcl-xL inhibitor ABT-263 acts in synergy with osimertinib in non-small cell lung cancer cells. (A) HCC827/OR cells were treated with a combination of osimertinib and ABT-263 or each individual agent and cell viability was determined using a MTT assay. (B) CI of osimertinib and ABT-263 was calculated using the Chou-Talalay method. (C and D) Colony formation assay was used to determine the effects of the concurrent treatment of HCC827/OR cells with both osimertinib and ABT-263. *P<0.05 vs. treatment alone or control group. CI, combination index.
