Recombinant human DNase I for the treatment of cancer-associated thrombosis: A pre-clinical study.

Cancer patients are more likely to develop thrombosis, and this co-morbidity is related to the worse prognosis of the disease. The increased formation of neutrophil extracellular traps (NETs) has been proposed as one of the mechanisms to explain cancer-associated thrombosis. In vivo, degradation of NETs with recombinant human DNase I (rhDNase I) prevents thrombus formation in mouse models.

IL-1β Blockade Attenuates Thrombosis in a Neutrophil Extracellular Trap-Dependent Breast Cancer Model.

Cancer patients are at increased risk of developing thrombosis, comorbidity that has been associated with increased neutrophil counts and the formation of neutrophil extracellular traps (NETs). Interleukin-1β (IL-1β) modulates the expression of granulocyte colony-stimulating factor (G-CSF), a cytokine that promotes cancer-associated neutrophilia and NET generation. Herein, we combined a murine breast cancer model with a flow-restriction thrombosis model to evaluate whether the IL-1β blockade could interfere with cancer-associated thrombosis.
