Table 2.

Chemoresistance, BRCA status, and homologous recombination (HR) status of HGSOC samples. IC50 values of cisplatin, determined by MTT viability assay. Genetic testing of samples was performed during clinical diagnosis. HR status was confirmed via foci formation assay (see Methods).

	Sample	Cisplatin (μm)	BRCA status	HR status
	PDX14	13	WT	Deficient
	PDX5	4.1	BRCA1 mutation	Proficient
	PDX9	5.8	WT	Proficient
	PDX1	25	WT	Deficient
	PDX3	6.0	WT	Proficient
	PDX8	1.5	Unknown	Deficient
	OVCAR8	6.8	WT a	Proficient
	PDX4	0.7	BRCA2 mutation	Deficient
	PDX6	0.4	BRCA2 mutation	Deficient
