Open AccessSingle-cell tumor-immune microenvironment of BRCA1/2 mutated high-grade serous ovarian cancer
The majority of high-grade serous ovarian cancers (HGSCs) are deficient in homologous recombination (HR) DNA repair, most commonly due to mutations or hypermethylation of the BRCA1/2 genes. We aimed to discover h...
