MetabolomicsVesicle-mediated mitochondrial clearance presents an actionable metabolic vulnerability in triple-negative breast cancer

Selective autophagy of mitochondria is known to promote survival and progression of cancer cells in various malignancies, including triple-negative breast cancer (TNBC). Here, we investigate the essential metabolic adaptations that support mitochondrial quality control in cancer cells with the ai...

MetabolomicsTargeting arginine metabolism reverses bone immunosuppressive microenvironment and metastasis in ARID1A-deficient triple negative breast cancer

Bone metastasis is a lethal consequence of breast cancer. AT-rich interaction domain 1A gene (ARID1A), a subunit of the switch/sucrose non-fermentable (SWI/SNF) complex, regulates immunosuppressive tumor microenvironment. ARID1A deficient triple negative breast cancer promotes bone metastasis.To ...

ProteomicsComparison of proteomic and phospho-proteomic analysis upon urea extraction and triple extraction
The goal of the present project was to investigate the applicability of a triple extraction (”TE”), which yields RNA, DNA and protein in a single procedure, for gel-free mass spectrometry-based proteomics. Proven successful for large-scale transcriptomics and genomics, we examined TE compatibility w...

TranscriptomicsGene-expression molecular subtyping of triple-negative breast cancer tumours: importance of immune response
Triple-negative (TN) breast cancers need to be refined in order to identify therapeutic subgroups of patients. We conducted an unsupervised analysis of microarray gene-expression profiles of 107 TN breast cancer patients and undertook robust functional annotation of the molecular entities found by ...

TranscriptomicsMolecular Characterization of Basal-like and Non-Basal-like Triple-Negative Breast Cancers
Triple-negative (TN) and Basal-like (BL) breast cancer definitions have been used interchangeably to identify breast cancers that lack expression of the hormonal receptors (HR) and overexpression and/or amplification of HER2. However, both classifications when compared to each other, show substantia...

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 ...

TranscriptomicsFZD7 Plays a Critical Role in Triple Negative Breast Cancer Proliferation
Breast cancer is genetically and clinically heterogeneous. Triple negative cancer (TNBC) is a subtype of breast cancer usually associated with poor outcome and lack of benefit from target therapy. A pathway analysis in a microarray study was performed using TNBC compared with non-triple negative bre...

TranscriptomicsTumor expression data from neoadjuvant trial of cisplatin monotherapy in triple negative breast cancer patients
Evidence suggests that BRCA1 mutation associated tumors have increased sensitivity to DNA damaging agents like cisplatin. Sporadic triple negative breast cancers (TNBC) have many phenotypic similarities to BRCA1 tumors and may have a similar sensitivity to cisplatin. We tested the efficacy of cisp...

TranscriptomicsCharacterization of macrophage - cancer cell crosstalk in estrogen receptor positive and triple-negative breast cancer
We performed whole transcriptome sequencing of human monocytes that were co-cultured with estrogen receptor positive (ER+) or triple-negative (TNBC) breast cancer cell lines and studied the biological responses related to the differential gene activation in both cell types to understand how differen...
