Topics Covered

• Endothelial apoptosis
• Role in tumor response to radiation therapy
• Tissue damage results from depletion of stem cells and cells with clonogenic capacity
• Radiation targets the DNA leading to reproductive (mitosis-associated) or apoptotic cell death
• Modifications of DNA damage recognition and repair pathways determine the level of tissue sensitivity to radiation
• Sphingomyelin
• Ceramide
• GI tract and bone marrow: very radiation responsive
• Growth patterns of tumors
• The two-target model for single-dose radiotherapy of experimental tumors
• Engaging the vascular component of tumor response to radiation
