(Submitter supplied) Triple negative breast cancer (TNBC) is an aggressive clinical phenotype, and accounts for 15% to 20% of all breast cancers. The molecular determinants of malignant cell behaviors in TNBC remain largely unknown. We find that the AP-1 transcription factor component, Fra-1, is overexpressed in basal-like breast tumors, and its expression level has high prognostic significance. Depletion of Fra-1 or its heterodimeric partner c-Jun inhibits the proliferative and invasive phenotypes in TNBC cells. more...

(Submitter supplied) Triple-negative breast cancer (TNBC) represents a highly aggressive form of breast cancer with limited treatment options. Proinflammatory cytokines such as TNF can facilitate tumor progression and metastasis. However, our knowledge of the molecular mechanisms underlying TNBC progression mediated by inflammation is still limited. Here, we define the AP-1 transcription factor c-Jun cistrome, which is comprised of 13800 binding sites responsive to TNFalpha-induced signaling in TNBC cells. more...

(Submitter supplied) Fra-1, a member of the activator protein 1 (AP-1) family, is overexpressed in triple-negative breast cancer (TNBC) and plays crucial roles in tumor growth. Here we report the identification of 118 proteins interacting with endogenous chromatin-bound Fra-1 in TNBC cells, highlighting DDX5 as the most enriched Fra-1-interacting protein. DDX5, a previously unrecognized protein in the Fra-1 transcriptional network, shows extensive overlap with Fra-1 cistrome and transcriptome that are highly associated with the TNBC cell growth. more...

(Submitter supplied) Fra-1, a member of the activator protein 1 (AP-1) family, is overexpressed in triple-negative breast cancer (TNBC) and plays crucial roles in tumor progression. However, a systematic analysis of the composition of the Fra-1 protein network specifically on chromatin is still missing. Here we performed endogenous purification of Fra-1 transcriptional complex under ChIP conditions, followed by mass spectrometry, to identify chromatin-bound partners of Fra-1 in TNBC cells. more...

(Submitter supplied) This study aimed to further our understanding of the role that hypermethylatioted in cancer 1 (HIC1) plays in breast cancer progression. Microarrays were searched for some genes that had correlated expression with HIC1 mRNA. According to fold-change screening between restoring expression of HIC1 and its respective control cells in MDA-MB-231 cells, or HIC1 knockdown and its respective control cells in HBL100, both up-regulated and down-regulated genes were shown.

(Submitter supplied) Based on the identified stress-independent cellular functions of activating transcription factor 4 (ATF4), we reported enhanced ATF4 levels in MCF10A cells treated with TGFβ1. ATF4 is overexpressed in triple negative breast cancer (TNBC) patients, but its impact on patient survival and the underlying mechanisms remain unknown. We aimed to determine ATF4 effects on breast cancer patient survival and TNBC aggressiveness, and the relationships between TGFβ and ATF4.

(Submitter supplied) Little is understood about the early molecular drivers of triple-negative breast cancer (TNBC), making the identification of women at risk and development of targeted therapy for prevention significant challenges. By sequencing a TNBC cell line-based breast cancer progression model we have found that miRNA-29c is progressively lost during TNBC tumorigenesis. In support of the tumor suppressive role of miRNA 29c, we found that low levels predict poor overall patient survival and, conversely, that ectopic expression of miRNA-29c in preneoplastic cell models inhibits growth. more...

(Submitter supplied) Breast cancer is a heterogeneous disease comprised of four molecular subtypes defined by whether the tumor-originating cells are luminal or basal epithelial cells. Breast cancers arising from the luminal mammary duct often express estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth receptor 2 (HER2). Tumors expressing ER and/or PR are treated with anti-hormonal therapies, while tumors overexpressing HER2 are targeted with monoclonal antibodies. more...
