The BH3 mimetic ABT-263 synergizes with the MEK1/2 inhibitor selumetinib/AZD6244 to promote BIM-dependent tumour cell death and inhibit acquired resistance

Tumour cells typically exhibit a G1 cell cycle arrest in response to the MEK1/2 [mitogen-activated protein kinase/ERK (extracellular-signal-regulated kinase) kinase 1/2] inhibitor selumetinib, but do not die, and thus they acquire resistance. In the present study we examined the effect of combini…
