Project description:Expression data from Breast cancer subtypes In a cohort study of primary invasive breast cancer (41 TN, 30 HER2, 29 Luminal A and 30 Luminal B) as well as 11 normal tissues samples and 14 cell lines , we obtained a tumor specimen at surgery before any patient treatment. Total RNA was extracted from all samples and the whole transcriptome was quantified with Affymetrix U133 Plus 2.0 Chips.

Project description:Triple negative breast cancer (TNBC) is characterized by high proliferation, poor differentiation and a poor prognosis due to high rates of recurrence. Despite lower overall incidence African American (AA) patients suffer from higher breast cancer mortality in part due to the higher proportion of TNBC cases among AA patients compared to European Americans (EA). It was recently shown that the clinical heterogeneity of TNBC is reflected by distinct transcriptional programs with distinct drug response profiles in preclinical models. In this study, we used gene expression profiling and immunohistochemistry to eluicidate potential differences between TNBC tumors of EA and AA patients on a molecular level. WG-DASL experiment of 90 FFPE samples of ER, PR and HER2 (triple) negative breast cancer samples diagnosed between 1987 and 2007. Invasive disease was identified on H&E sections by the study pathologist and one to three 1.5 mm cores were punched from the top down in the designated tumor areas of each FFPE block. The cores were deparaffinized with xylene at 50°C for 3 minutes. RNA was extracted using the RecoverAll Total Nucleic Acid Isolation kit (Applied Biosystems) following the manufacturer's protocol. The isolated RNA was hybridized to Whole-Genome DASL (HumanRef8 V 3.0, Illumina) at the Yale Center for Genome Analysis. 90 primary tumor RNA samples from 90 patients were adequate for analysis and passed Quality control.

Project description:Eribulin prolongs overall survival in patients with pre-treated advanced breast cancer. However, no biomarker exists to prospectively select patients who will benefit the most from this drug. SOLTI-1007-NeoEribulin is a phase II, open-label, two cohort, exploratory pharmacogenomic study in patients with clinical stage I-II HER2-negative breast cancer receiving neoadjuvant eribulin monotherapy treatment. Primary objective was to explore the association of baseline tumor gene expression with pathological complete response in the breast (pCRB) at surgery. Key secondary objectives were pCRB rates in all patients and according to HR status, gene expression changes during treatment and safety. 101 hormonal receptor-positive (HR+) and 73 triple negative breast cancer (TNBC) patients were recruited. The pCRB rates were 6.4% in all patients, 4.9% in HR+ disease and 8.2% in TNBC. The TNBC cohort was interrupted due to a progression disease rate of 30.1%. The pCRB rates differed according to intrinsic subtypes: 28.6% in HER2-E, 11.1% in Normal-like, 7.9% in Luminal B, 5.9% in Basal-like and 0% in Luminal A (HER2-E vs. others odds ratio=7.05, 95% CI 1.80-42.14; p-value = 0.032). Intrinsic subtype changes at surgery occurred in 33.3% of cases, mostly (49.0%) Luminal B converting to Luminal A or Basal-likes converting to Normal-like. Baseline tumor infiltrating lymphocytes (TILs) were significantly associated with pCR. Eribulin showed a good safety profile with a low response and pCRB rates. Patients with HER2-negative disease with a HER2-enriched profile may benefit the most from eribulin. In addition, significant biological activity of eribulin is observed in Luminal B and Basal-like subtypes.

Project description:Peripheral blood CD8+ T-lymphocytes play a crucial role in cell-mediated immunity and tumour-related immune responses in breast cancer. The protein profile analysis of CD8+ T-lymphocytes in benign, Luminal A, Luminal B and triple-negative breast cancer (TNBC) patients in comparison to healthy control via a label-free proteomic quantification and gene set enrichment analysis (GSEA) were performed. The results confirmed that the most significantly of RNA degradation signalling pathway was down-regulated in all groups (benign, Luminal A, Luminal B, TNBC) was observed. Given the immunological role that T cells play in the treatment of disease, a better knowledge of RNA metabolism, i.e., the role that mRNA degradation pathways play in human physiology and pathology may lead to novel approaches to the therapeutic use of T cells.

Project description:Triple negative breast cancers (TNBC) are associated with poor clinical outcomes due to a lack of targeted therapies. Here, we identified a small molecule ERX-41 with potent activity against TNBC cell lines, primary tumor explants and xenografts. ERX-41 induced endoplasmic reticulum (ER) stress and caused cell death. We identified lysosomal acid lipase A (LIPA) gene as the molecular target for ERX-41 and critical for ERX-41 to induce ER stress and cell death. Mechanistically, interaction of ERX-41 with LIPA alters expression of multiple ER-resident proteins involved in protein folding. Importantly, we defined that ER localization of LIPA but not its lipase function are necessary for ERX-41 activity in TNBC. Our study implicates a new targeted strategy for multiple solid tumors, including breast, brain, pancreatic and ovarian, whereby a small orally bioavailable molecule (ERX-41) targeting LIPA blocks protein folding, induces ER stress and causes cell death.
