In vitro

Las concentraciones micromolares de niraparib radiosensibilizan las líneas celulares tumorales derivadas de cánceres de pulmón, mama y próstata independientemente de su estado p53, pero no las líneas celulares derivadas de tejidos normales. El niraparib también sensibiliza las células tumorales al H2O2 y convierte las roturas de cadena sencilla (SSBs) inducidas por H2O2 en DSBs durante la replicación del ADN.

In vivo

MK-4827 mejora fuertemente el efecto de la radiación en una variedad de xenoinjertos tumorales humanos, tanto de tipo salvaje p53 como mutantes de p53. MK-4827 reduce los niveles de PAR en tumores 1 h después de la administración, lo que persistió hasta 24 h. El tratamiento in vivo con MK-4827 y radiación prolongó la supervivencia (p<0,01) en comparación con las modalidades individuales. La superioridad in vivo de MK-4827 más radiación se documenta además por elevaciones significativas de la caspasa-3 escindida y γ-H2AX en tumores del grupo de combinación en comparación con las cohortes de modalidad única.
