In multiple tumor types, activation of the transcription factor NF-κB increases the resistance of tumor cells to anticancer therapies and contributes to tumor progression. Genotoxic stress induced by chemotherapy or radiation therapy triggers the ATM-dependent translocation of NF-κB essential modifier (NEMO), also designated IκB kinase γ (IKKγ), from the(More)
High-risk human papillomaviruses, such as HPV16, cause cervical cancers, other anogenital cancers, and a subset of head and neck cancers. E6 and E7, two viral oncogenes expressed in these cancers, encode multifunctional proteins best known for their ability to bind and inactivate the tumor suppressors p53 and pRb, respectively. In skin carcinogenesis(More)
The deubiquitinating enzyme CYLD is a tumor suppressor protein known for its role in repression of generally pro-oncogenic NF-kappaB activation pathways. Two new studies published in this and the September issue of Developmental Cell show that CYLD dismantles distinct types of polyubiquitin chains formed on select signaling proteins and is thereby required(More)
The development of specialized organs is tightly linked to the regulation of cell growth, orientation, migration and adhesion during embryogenesis. In addition, the directed movements of cells and their orientation within the plane of a tissue, termed planar cell polarity (PCP), appear to be crucial for the proper formation of the body plan. In Drosophila(More)
