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 764: A role for GLI1 in the development of multidrug resistance in rhabdomyosarcoma (RMS) cells
RMS is the most common sarcoma of childhood. About 30% of patients with localized tumors will recur following treatment. The outcome for patients with recurrent RMS remains poor. Therefore, development of chemotherapy resistance during RMS therapy represents an important problem and novel approaches to prevent or reverse drug resistance are essential. Activation of multidrug transporter genes, including MDR1, MRP1, LRP and TAP1 represents an important mechanism for drug resistance in RMS. However, the mechanism of expression of multidrug resistance genes in RMS is incompletely understood. Recent reports have suggested a ro...
