Cell cycle arrest in mitosis promotes interferon-induced necroptosis.

ABSTRACT: Resistance to apoptosis is a hallmark of cancer and deregulation of apoptosis often leads to chemoresistance. Therefore, new approaches to target apoptosis-resistant cancer cells are crucial for the development of directed cancer therapies. In the present study, we investigated the effect of cell cycle regulators on interferon (IFN)-induced necroptosis as an alternative cell death mechanism to overcome apoptosis resistance. Here, we report a novel combination treatment of IFNs with cell cycle arrest-inducing compounds that induce necroptosis in apoptosis-resistant cancer cells and elucidate the underlying molecular mechanisms. Combination treatment of IFNs (i.e. IFNβ) with inhibitors of the cell cycle (e.g. vinorelbine (VNR), nocodazole (Noc), polo-like kinase-1 (Plk-1) inhibitor BI 6727)
