    摘要: Provided are methods for therapy or prophylaxis of genotoxic stress. The methods include administering to an individual in need an effective amount of Matrix Metalloproteinase (MMP)-9. The individual in need may have or be at risk of developing Acute Radiation Syndrome (ARS), or may have received or is receiving chemotherapy, or has insufficient hematopoietic function. The present disclosure provides results from a mouse model of lethal ARS induced by TBI to demonstrate that neutrophils (N ) are essential mediators of the radiomitigative but not radioprotective abilities of entolimod, express functional TLR5 but undergo minimal transcriptional changes post-entolimod suggesting that N mitigate 30 ARS through a transcriptional-independent mechanism; and increase the number of active hematopoietic pluripotent precursors (HPPs) in bone marrow.
