(Submitter supplied) Noncoding transcription is a defining feature of active enhancers, linking transcription factor (TF) binding to the molecular mechanisms controlling gene expression. To determine the relationship between enhancer activity and biological outcomes in breast cancers, we profiled the transcriptomes (using GRO-seq and RNA-seq) and epigenomes (using ChIP-seq) of 13 different breast cancer cell lines representing the five major molecular subtypes of breast cancer. more...

(Submitter supplied) Chromatin architecture is essential to transcriptional regulation. Cancer cells undergo critical chromatin remodeling processes that interact with the activation or silencing of oncogenes or tumor suppressor genes. These processes, together with other alterations of the functional status of chromatins, are characterized by epigenetic marks such as covalent histone modifications, DNA methylations and etc. more...

(Submitter supplied) Although technological advances now allow increased tumor profiling, a detailed understanding of the mechanisms leading to the development of different cancers remains elusive. Our approach towards understanding the molecular events that lead to cancer is to characterize changes in transcriptional regulatory networks between normal and tumor tissue. Because enhancer activity is thought to be critical in regulating cell fate decisions, we have focused our studies on distal regulatory elements and transcription factors that bind to these elements. more...

(Submitter supplied) RNA samples were prepared from freshly sorted mammary cell subpopulations (MaSC/basal-enriched, luminal progenitor, mature luminal and stromal) from five sets of adult mice. High throughput RT-PCR was used to measure the global microRNA expression profiles of each cell subpopulation. The expression profiles were compared between cell subpopulations to gain insight into the regulation of lineage-restricted genes.

(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 onset and progression of breast cancer are linked to genetic and epigenetic changes that alter the normal programming of cells. Epigenetic modifications of DNA and histones contribute to chromatin structure that results in the activation or repression of gene expression. Several epigenetic pathways have been shown to be highly deregulated in cancer cells. Targeting specific histone modifications represents a viable strategy to prevent oncogenic transformation, tumor growth or metastasis. more...

(Submitter supplied) Activation of transcription enhancers, especially super enhancers, is one of the important epigenetic features of tumorigenesis. However, only very few studies reported how the enhancer landscape evolves during tumorigensis. Here we utilized a proteomics approach and found that H3K27ac and H4K8ac are elevated in the mammary tumor of MMTV-PyVT mouse model, which was then confirmed by IHC results in human BRCA chips. more...
