(Submitter supplied) Mechanisms driving tumor progression from less aggressive subtypes to more aggressive states represent key targets for breast cancer therapy. We identified a subset of Luminal A primary breast tumors to give rise to HER2-enriched (HER2E) subtype metastases, but remain clinically HER2 negative (cHER2-). By testing the unique genetic and transcriptomic features of these cases, we developed the hypothesis that fibroblast growth factor receptor 4 (FGFR4) drives this subtype switching. more...

(Submitter supplied) The seed-and-soil hypothesis was described over a century ago to describe why cancer cells (seeds) grow in certain organs (soil). Since then, the genetic properties that define the cancer cells have been heavily investigated, however, the genetic mediators within the organ microenvironment that mediate successful metastatic growth are less understood. In these studies, a set of human breast cancer patient-derived xenograft (PDX) metastasis models were utilized. more...

(Submitter supplied) MDA-MB-231 human breast cancer cells were injected orthotopiclly into mammary glands 4 of female NOD SCID mice 4-weeks after sub-cutaneous implantation of human femoral bone chips. Primary tumour, bone chips containing metastatic deposits and naive bone chips were isolated and mRNA analysed for gene expression to determine genetic signitures associated with breast cancer bone metastasis.

(Submitter supplied) We treated nine lines of breast cancer cells with conditioned medium derived from NAF and CAF to study the paracrine interaction beetween stroma and tumor. Gene expression profiles for breast cancer cell lines are reported after 72h of treatment with conditioned medium derived from NAF and CAF or with control media.

(Submitter supplied) Breast cancer subtypes identified in genomic studies have different underlying genetic defects. Mutations in the tumor suppressor p53 occur more frequently in estrogen receptor (ER) negative, basal-like and HER2-amplified tumors than in luminal, ER positive tumors. Thus, because p53 mutation status is tightly linked to other characteristics of prognostic importance, it is difficult to identify p53's independent prognostic effects. more...

(Submitter supplied) RNA-sequencing analysis of RBP2 overexpressing MCF7 cell lines. RBP2 (also known as JARID1A), a member of the JARID1 family of histone H3 lysine K4 demethylases, has been considered to have an oncogenic potential in several cancer including breast cancer. Results provide insight into the transcriptional regulation of RBP2 in estrogen receptor positve breast cancer.

(Submitter supplied) Breast cancer metastasis is the leading cause of breast cancer-related mortalities in women. Differential gene expression programs enriched in the primary tumor is able to distinguish patients that experience relapse to different organs. Epigenomic changes often underlie transcriptomic differences and give rise to stable phenotypes. However, the epigenomic differences present in organotropic metastasis remains underexplored. more...

(Submitter supplied) The study of breast cancer pathogenesis relies heavily on the use of established cell lines often derived from metastatic lesions, which while having significantly contributed to the knowledge of breast cancer biology may inadvertently limit the understanding of the mechanisms governing the metastatic process. Our goal was to establish primary cultures from dissociation of breast tumors in order to provide cellular models that may better recapitulate breast cancer pathogenesis and the metastatic process. more...

(Submitter supplied) Estrogen receptor alpha (ERα)-positive breast cancers, while initially being responsive, eventually develop resistance to ERα targeted therapies through ERα-dependent and ERα-independent mechanisms. Through functional genomic studies we report heretofore unrecognized role for the axon guidance dependence receptor UNC5A in fine-tuning estradiol (E2) and anti-estrogen response. Knockdown of the estradiol-inducible UNC5A caused unrestricted ERα signaling as evident from deregulated E2-regulated gene expression and E2-independent tumorigenesis accompanied with multi-organ metastatic spread in xenograft models. more...

(Submitter supplied) The central nervous system (CNS) is a common site of metastatic disease in patients with breast cancer and has few therapeutic options with dismal outcomes. The purpose of our study was to identify common and rare events that underlie breast cancer CNS metastasis. We performed deep genomic profiling, which integrated gene copy number, gene expression and DNA methylation datasets on a collection of breast brain metastases. more...

(Submitter supplied) Brain metastatic disease occurs in 10-30% of metastatic breast cancer cases. The incidence of brain metastases is increasing with median overall survival < 2 years for patients. In order to better characterize oncogenic pathway activity pertinent to breast cancer brain metastasis, exome capture RNA sequencing was carried out on patient matched primary breast with brain metastatic tumor samples for 45 cases of breast cancer brain metastasis (N= 90 samples). more...
