Complement C5b-9 and Cancer: Mechanisms of Cell Damage, Cancer Counteractions, and Approaches for Intervention
In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

Abstract 3966: PLK1 regulates PAX3-FOXO1 stability and its inhibition mediates regression of alveolar rhabdomyosarcoma xenograft tumors
Oncogenic addiction provides an opportunity to develop new treatment options, especially for childhood cancers. Pediatric tumors contain a lower number of oncogenic mutations compared to most adult cancers, suggesting stronger dependency on individual oncogenes, such as chimeric transcription factors that have the ability to control multiple oncogenic pathways. Taking advantage of this addiction, targeting of oncogenic transcription factors becomes a new powerful strategy for therapy of translocation positive pediatric tumors like alveolar rhabdomyosarcoma (aRMS), which is characterized by a very dismal prognosis. As trans...
