Sheta et al. used microarray analysis founding that in ascites-derived primary cell cultures (AsPCs)-matched (Highly-grade serous ovarian cancer)HGSOC tumors, C-MET, CDKN2A, N-cadherin and P-glyc/ABCB1 significantly express low levels in PARP inhibitor sensitive AsPCs while SPRY2, E-cadherin and FANCFex express high levels. This evidence concerns the gene PARP1 and ovarian serous adenocarcinoma.
