1 LMW-E expression overcame cell-cycle inhibition by AIs in a CDK2/Rb-dependent manner, and inhibition of CDK2 by dinaciclib reversed LMW-E-mediated resistance, whereas treatment with palbociclib, a CDK4/6 inhibitor, did not.Conclusions: Collectively, these findings suggest that cell-cycle deregulation by LMW-E mediates resistance to AIs and a combination of CDK2 inhibitors and AIs may be an effective treatment in patients with HR-positive tumors that express LMW-E. Clin Cancer Res; 23(23); 7288-300. dinaciclib cyclin dependent kinase 2 Homo sapiens
