摘要:
The present invention concerns methods and compositions involving inhibitors and enhancers of RAD51, a protein involved in homologous recombination. In some embodiments, the present invention concerns methods for stimulating homologous recombination, which has a number of significant research and clinical applications. In certain other embodiments, there are methods for protecting cells using a compound that enhances RAD51 activity. Such enhancers may also be employed to prevent or reduce damage to cells that may be caused by DNA damaging agents. In other embodiments, there are methods for sensitizing cells to the effects of DNA damaging agents, which can have particular applications for cancer patients. In some embodiments of the invention, the RAD51 enhancer or inhibitor is a small molecule that directly affects RAD51 activity, such as its ability to promote filament formation.

The invention relates to treatment of primary and secondary tumors using a therapeutic combination including ionizing radiation and gene therapy comprising mutant-LIGHT. Methods of treating a tumor and inducing an anti-tumor immune response are also provided.
摘要:
In some embodiments, an image-guided radiotherapy apparatus and method is provided in which a radiotherapy radiation source and a gamma ray photon imaging device are positioned with respect to a patient area so that a patient can be treated by a beam emitted from the radiotherapy apparatus and can have images taken by the gamma ray photon imaging device. Radiotherapy treatment and imaging can be performed substantially simultaneously and/or can be performed without moving the patient in some embodiments. The gamma ray photon imaging device can be coupled and movable with respect to any part of a building structure, can be located on a portable frame movable to and from the radiotherapy radiation source and patient, or can take other forms. In some embodiments, the gamma ray photon imaging device can be used for imaging in connection with other types of medical interventions.
摘要:
The present invention relates to the signalling pathways connecting DNA damage, such as that induced by ionizing radiation or alkylating agents, and phosphorylation by tyrosine kinases.
