(Submitter supplied) Gene expression profiles of normal human mammary tissue from BRCA1 mutation carriers, non-BRCA1/2 mutation carriers and normal women. RNA was prepared from normal breast tissue (confirmed by pathology) from reduction mammoplasties (n=5) and prophylactic mastectomies of known BRCA1 (n=7) and non-BRCA1/2 mutation carriers (n=8). non-BRCA1/2 carriers were individuals with a strong family history of breast cancer (kConFab Category 1 (http://www.kconfab.org/Collection/Eligibility.shtml) where no mutation in BRCA1 or BRCA2 has been identified in the family by high sensitivity testing (http://www.kconfab.org/Progress/Sensitivity.shtml) of any individual affected by breast or ovarian cancer. more...

(Submitter supplied) To delineate epithelial subpopulations in human mammary tissue, hematopoietic and endothelial cells were depleted from freshly isolated cell suspensions derived from reduction mammoplasties by fluorescence-activated cell sorting. The resultant Lin- population was fractionated into four distinct subpopulations using CD49f (α6-integrin) and epithelial cell adhesion molecule (EpCAM; also referred to as CD326 and ESA). more...

(Submitter supplied) Brca2(fl/fl)Trp53(fl/fl) mice were crossed with MMTV-cre mice to create mice with both alleles of Brca2 and one allele of Trp53 deleted (refered to as Brca2KO). Mature luminal, luminal progenitor and basal mammary epithelial cell populations were sorted from Brca2KO and wildtype mice. Transcriptional profiling revealed marked perturbation within the luminal Brca2KO compartment

(Submitter supplied) We generate induced pluripotent stem cells (iPSCs) from healthy individuals and young ovarian cancer patients with germline pathogenic BRCA1 mutations. We then differentiate them into a human iPSC-derived fallopian tube organoid model. We recapitulated BRCA1 mutant ovarian carcinogenesis in vitro and showed tumors in vivo. Using the IPSC derived fallopian tube organoid model, we identify a unique transcriptional profile associated with BRCA1 mutation similar to the ovarian cancer profile.

(Submitter supplied) Women with germline mtuation in BRCA1 have increased risk for developing hereditary breast cancer. The role of the epitheilum-assocaited niche during BRCA1-driven tumor intiation remains unclear. Here, we show that the pre-malignant stromal niche promotes epithelial prolifeation and BRCA1-driven cancer intiation in trans. Using single-cell RNA seq analysis of human pre-neoplastic BRCA1 and control breast tissue, we show that stromal cells provide numerous pro-proliferative paracrine signals inducing epithelial proliferation.

(Submitter supplied) Most BRCA1-deficient BLBCs carry a dysfunctional INK4-RB pathway. Thus, we have created genetically engineered mice with Brca1 loss and deletion of p16INK4A, or separately p18INK4C, to model the deficient INK4-RB signaling in human BLBC. By using these mutant mice and human BRCA1 deficient and proficient breast cancer tissues and cells, we tested if there exists a druggable target in BRCA1 deficient breast cancers.

Cells isolated from both treatment arms were pooled and injected into the fat pad of FvB recipients (passage 2) in limiting dilutions (mimicking occult disease) and again randomized 1:1 for additional RANK-Fc (adjuvant) or mock treatment
