MetabolomicsCommon Metabolic Pathways Implicated in Resistance to Chemotherapy Point to a Key Mitochondrial Role in Breast Cancer
Cancer cells are known to reprogram their metabolism to adapt to adverse conditions dictated by tumor growth and microenvironment. A subtype of cancer cells with stem-like properties, known as cancer stem cells (CSC), is thought to be responsible for tumor recurrence. In this study, we demonstrated ...

MetabolomicsFatty acid oxidation protects cancer cells from apoptosis through increasing mitochondrial membrane lipids

Overcoming resistance to chemotherapies remains a major unmet need for cancers such as triple negative breast cancer (TNBC). Therefore, mechanistic studies to provide insight for drug development are urgently needed to overcome TNBC therapy resistance. Recently, an important role of fatty acid β-...

MetabolomicsMetabolomics Identifies Metabolic Markers of Maturation in Human Pluripotent Stem Cell-Derived Cardiomyocytes
Cardiovascular disease is a leading cause of death worldwide. Human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) hold immense clinical potential and recent studies have enabled generation of virtually pure hPSC-CMs with high efficiency in chemically defined and xeno-free conditions. Despi...

MetabolomicsArginine starvation kills tumor cells through aspartate exhaustion and mitochondrial dysfunction
Defective arginine synthesis, due to the silencing of argininosuccinate synthase 1 (ASS1), is a common metabolic vulnerability in cancer, known as arginine auxotrophy. Understanding how arginine depletion kills arginine-auxotrophic cancer cells will facilitate the development of anti-cancer therapeu...

TranscriptomicsProlonged Drug Selection of Breast Cancer Cells and Enrichment of Cancer Stem Cell Characteristics.
Background: Cancer stem cells are presumed to have virtually unlimited proliferative and self-renewal abilities and to be highly resistant to chemotherapy, a feature that is associated with overexpression of ATP-binding cassette transporters. We investigated whether prolonged continuous selection of...

TranscriptomicsMicroarray analyses of microRNA expressions in comparison with immortal healthy mammary epithelial cells, breast cancer cells, and long-term-cultured breast cancer stem cells
RNA extraction and microarray analysis total RNA from immortalized normal mammary epithelial cells (184A1, MCF-12A), breast cancer cells (MDA-MB-231, MCF-7, MDA-MB-468, SK-BR-3), BCSC (MDA-MB-231SC, MCF-7SC, XM322, XM607). MDA-MB-231SC and MCF-7SC originating from breast cancer cell lines; XM322 and...

TranscriptomicsTranscription profiling of mouse cancer stem cells in MMTVWnt-1 murine breast tumors
In human breast cancers, a phenotypically distinct minority population of tumorigenic cancer (TG) cells (sometimes referred to as cancer stem cells) drives tumor growth when transplanted into immunodeficient mice. Our objective was to identify a mouse model of breast cancer stem cells that could hav...

TranscriptomicsTGF-beta specific gene expression signatures in breast cancer stem cells
Analyze TGF-beta pathway transcriptional regulation in breast cancer stem cells with different responses upon TGF-beta pathway activation. Total RNA from four breast cell lines grown as mammospheres treated with recombinant TGF-beta or a TGF-beta receptor I inhibitor was used in the analysis.

TranscriptomicsExpression data of ALDH+ breast cancer cells
It has been suggested that breast cancers are driven and maintained by a cellular subpopulation with stem cell properties. These breast cancer stem cells (BCSCs) mediate metastasis and by virtue of their resistance to radiation and chemotherapy, contribute to relapse. Although several BCSC markers ...

TranscriptomicsHMGA1: A master regulator of tumor progression in triple-negative breast cancer cells
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 ...
