TCOF1 DRIVES STEMNESS OF TRIPLE-NEGATIVE BREAST CANCER THROUGH KIT

Project description:Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with poor prognosis. The high malignancy of TNBC is contributed by its heterogeneity and enrichment of cancer stem cells. By performing multiomic profiling, we recently uncovered super-enhancer heterogeneity between breast cancer subtypes. Here, we identify TCOF1 as a novel super-enhancer-regulated gene that promotes TNBC growth and stemness. TCOF1, which plays a critical role in craniofacial development, is frequently upregulated in TNBC and its elevated expression correlates with shorter overall survival. Whereas TCOF1 depletion has potent effects on the growth and stemness of basal-like TNBC, it has no effect on mesenchymal-like cells, highlighting the distinct molecular dependency in different subgroups of TNBC. Whole genome RNA sequencing uncovers several stem cell molecules regulated by TCOF1. We further demonstrate that the upregulation of KIT by TCOF1 mediates TNBC stemness. These findings provide a rationale for developing therapeutics targeting TCOF1 in basal-like TNBC.

HMGA1: A master regulator of tumor progression in triple-negative breast cancer cells

Project description:Emerging evidence suggests that tumor cells metastasize by co-opting stem cell transcriptional networks, although the molecular underpinnings of this process are poorly understood. Here, we show for the first time that the high mobility group A1 (HMGA1) gene drives metastatic progression in triple negative breast cancer cells (MDA-MB-231) by reprogramming cancer cells to a stem-like state. We discovered an HMGA1 signature in triple negative breast cancer cells that is highly enriched in embryonic stem cells. Together, these findings indicate that HMGA1 is a master regulator of tumor progression in breast cancer by reprogramming cancer cells through stem cell transcriptional networks. Future studies are needed to determine how to target HMGA1 in therapy. HMGA1 was knocked-down in MDA-MB-231 cells using siRNA as we previously described (Tesfaye A 2007). RNA from three independent knockdown experiements along with 3 control populations were collected by Rneasy miniprep (Qiagen) and analyzed by Affymetrix Human Exon 1.0 ST platform.

Triple Negative Breast tumors: SPARC Positive Tumors vs SPARC Negative Tumors

Project description:The aim of this study was evaluate the transcriptome changes in the comparison between triple negative tumors with increased SPARC expression and triple negative tumors with decreased SPARC expression according to Nagai et al., 2011 (Breast Cancer Res Treat (2011) 126:1–14) The results generated could be of particular interest to better define the prognostic impact of SPARC expression in triple negative breast tumors
