摘要:
This present invention relates compositions and methods of treating cancer and methods of accessing/monitoring the responsiveness of a cancer cell to a therapeutic compound, specific for a DNA repair pathway. A method for treating cancer is provided, which includes: a) determining whether the cancer cell is deficient in a DNA repair pathway (eg. Fanconi anemia) and b) administering a DNA damaging agent or inhibitor specific for at least one different DNA repair pathway than that identified in step (a) (eg. mismatch repair or non-homologous endjoining repair pathways).
摘要:
The present invention discloses methods for detecting exposure of a living subject to genotoxic agents, testing sensitivity to a genotoxic agent, and determining DNA damage caused by exposure to an agent, comprising detecting the presence of FANCD2-containing foci from a sample collected from said subject. The presence of concentrated foci is indicative of DNA damage, and the degree of foci formation is correlated with degree of exposure. Diagnostic reagents contain a ligand that binds to human FANC~2 associated with a detectable label, Kits for detecting DNA damage in a biological sample contain such diagnostic reagents and signal detection components. The invention further discloses methods for identifying agents which modulate the ability of ~ANCD2-containing foci to form. Among other things, such agents are potentially useful chemosensitizing agents or may confer protection against damage caused by genotoxic agents.
