(Submitter supplied) The mammary epithelia are mainly composed of two distinct lineages, the basal and luminal cells. In our MMTV-Cre; Brca1flox/flox mouse model, we found the Brca1 knockout mainly occurred in the luminal cells, which will lead the mammary tumorigenesis. To investigate the Brca1 deficiency mediated mammary tumorigenesis, we sorted the luminal cells from wild type mice and MMTV-Cre; Brca1flox/flox mice for RNAseq analysis.

(Submitter supplied) Brca1 mutation predisposes women to early onset of breast and ovarian cancers.Through its diverse functions in DNA damage repair, cell cycle control, transcription regulation, ubiquitination and so on, BRCA1 acts as a very significant tumor suppressor and genomic safeguard. Brca1 deficiency induces severe cellular stress, when occurring in the mammary glands, it impairs the regular developmental process and eventually causes tumorigenesis due to accumulation of genome instability and other mechanisms. more...

(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.

(Submitter supplied) The Net1 RhoGEF has been implicated in invasive behavior in vitro, but its impact on tumorigenesis and metastasis in vivo has not yet been established. We developed Net1 knockout mice and profiled the transcriptomes of the resulting tumors to assess impact on pathway activation.

(Submitter supplied) We aimed to understand the transcriptome patterns of organ-derived cancer cell isolates from MMTV-PyMT mice. Tissues from primary tumors and organs harboring distal metastases were harvested from cancer bearing female mice. Although metastatic progression from primary tumors to lung tissue is well studied in the MMTV-PyMT model, metastases to other distal organs and the significance of intratumor heterogeneity across metastases from distal organs remain unclear. more...

(Submitter supplied) Breast tumors are characterized by inherent heterogeneity but the evolving cellular organization of breast tumors through progression remains poorly understood. Individual clones were tracked by combining mouse models of breast cancer with Confetti reporter strains. Expression profiling of individual clones sorted from tumors arising in K5- and Elf5-driven Pten/p53-deficient mice revealed distinct molecular signatures.

(Submitter supplied) BRCA1 mutation-carriers are predisposed to develop Basal-like breast cancer (BLBC), and p53 mutations are present in the majority of human BLBC cases, suggesting loss of these two tumor suppressors play key roles in development of BLBC. Recent studies suggest that the majority of human breast cancers, including BLBC, may originate from mammary epithelial cells (MECs) in the luminal lineage. However, how loss of p53 and BRCA1 contributes to development of BLBC from luminal MECs remains largely elusive. more...

(Submitter supplied) We have developed novel genetically engineered mouse mammary cancer models that develop hormone receptor-positive or -negative tumors depending on the combination of genetic abrrations induced in tumors. Tumors with loss of Brca1 and Trp53 are hormone receptor (HR) negative and tumors with or without Brca1 loss together with concomitant loss of Trp53 and inhibition of proteins of Rb family (Rbf) are HR positive. more...

(Submitter supplied) MicroRNAs (miRNAs) are small, non-coding, endogenous RNAs involved in many human diseases including breast cancer. miRNA expression profiling of human breast cancers has identified miRNAs related to the clinical diversity of the disease and potentially provides novel diagnostic and prognostic tools for breast cancer therapy. In order to further understand the roles of miRNAs in association with oncogenic drivers and in specifying sub-types of breast cancer, we performed miRNAexpression profiling on mammary tumors from eight well-characterized genetically -engineered Mouse (GEM) models of human breast cancer including MMTV–H-Ras, -Her2/neu, -c-Myc, -PymT, –Wnt1 and C3(1)/SV40 T/t-antigen transgenic mice, BRCA1fl/fl;p53+/-;MMTV-cre and the p53fl/fl ;MMTV-cre transplant model.

The gene expression data will be combined with the miRNA gene expression data from the corresponding mammary tumors and tissues for integrated miRNA and mRNA gene expression analysis, which are useful in improving the identification of miRNA targets from potential targets identified in silico.

(Submitter supplied) The BRCA1 tumor suppressor gene encodes a multi-domain protein for which several functions have been described. These include a key role in homologous recombination repair (HRR) of DNA double-strand breaks (DSBs), which is shared with two other high-risk hereditary breast cancer suppressors, BRCA2 and PALB2. Although both BRCA1 and BRCA2 interact with PALB2, BRCA1 missense variants affecting its PALB2-interacting coiled-coil domain are considered sequence variants of uncertain clinical significance (VUS). more...
