Homologous Recombination Deficiency: Exploiting the Fundamental Vulnerability of Ovarian Cancer.
UNLABELLED Approximately 50% of epithelial ovarian cancers (EOC) exhibit defective DNA repair via homologous recombination (HR) due to genetic and epigenetic alterations of HR pathway genes. Defective HR is an important therapeutic target in EOC as exemplified by the efficacy of platinum analogues in this disease, as well as the advent of PARP inhibitors, which exhibit synthetic lethality when ...
متن کاملHomologous recombination deficiency (HRD) testing in ovarian cancer clinical practice: a review of the literature
Until recently our knowledge of a genetic contribution to ovarian cancer focused almost exclusively on mutations in the BRCA1/2 genes. However, through germline and tumor sequencing an understanding of the larger phenomenon of homologous recombination deficiency (HRD) has emerged. HRD impairs normal DNA damage repair which results in loss or duplication of chromosomal regions, termed genomic lo...
متن کاملProgress in the treatment of ovarian cancer-lessons from homologous recombination deficiency-the first 10 years.
For several years, a major obstacle in the systemic treatment of ovarian cancer has been the lack of a therapeutic strategy tailored to specific biomarkers present in the individual patient's tumour. However, considerable progress has been made recently through the development of drugs targeting cells deficient in the key mechanism of double-strand DNA repair, known as homologous recombination ...
متن کاملIntratumor Heterogeneity of Homologous Recombination Deficiency in Primary Breast Cancer.
Purpose: The 3-biomarker homologous recombination deficiency (HRD) assay measures the number of telomeric allelic imbalances, loss of heterozygosity, and large-scale state transitions in tumor DNA and combines these metrics into a single score that reflects DNA repair deficiency. The goal of this study is to assess the consistency of these HRD measures in different biopsies from distinct areas ...
متن کاملDesigning E1 Deleted Adenoviral Vector by Homologous Recombination
Adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. In spite of their usefulness, the construction of adenoviral vectors (AdV) is a cumbersome and lengthy process that is not readily amenable to the generat...
