The results revealed that increased expression of miRNA-9 inhibits tumour growth in mice during the treatment with PARP1 AG014699 inhibitors: (PARP-1 inhibitor plus miRNA-9 agomiR: mean tumor volume = 14.3 mm3, vehicle alone: mean tumor volume = 178.8 mm3) [22]. This evidence concerns the gene PARP1 and neoplasm.
