Fig. 1From: Cytotoxic and targeted therapy for hereditary cancersSelective sensitivity of BRCA1/2-associated tumors to genotoxic agents. Normal cells from BRCA1/2 mutation carriers retain full capacity of genome maintenance mechanisms (left). Development of tumors in these patients involves somatic inactivation of the remaining BRCA1/2 allele, therefore malignant cells are unable to cope with double-strand DNA breaks (right)Back to article page
