Abstract Background Mantle cell lymphoma (MCL) is an aggressive B-non-Hodgkin lymphoma with generally poor end result. MCL is definitely characterized by an aberrantly high cyclin D1-driven CDK4 activity. New molecular targeted therapies such as inhibitors of the ubiquitin-proteasome system (UPS) have shown promising results in preclinical studies and MCL individuals. Our previous study revealed stabilization of the short-lived pro-apoptotic NOXA as a critical determinant for level of sensitivity to these inhibitors. It is currently unclear how cyclin D1 overexpression and aberrant CDK4 activity impact NOXA stabilization and treatment effectiveness of UPS inhibitors in MCL. Methods The effect of cyclin D1-driven CDK4.
