- Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
A randomized, open-label, multicenter, phase II trial (NCT00455533) enrolled previously untreated women with histologically-confirmed primary invasive breast adenocarcinoma (T23, N03, M0, tumor size 2.0 cm), regardless of hormone receptor or HER2 expression status. Patients received sequential neoadjuvant therapy starting with 4 cycles of AC (doxorubicin 60 mg/m2 intravenously and cyclophosphamide 600 mg/m2 intravenously) given every 3 weeks, followed by 1:1 randomization to either ixabepilone (40 mg/m2 3-hour infusion) every 3 weeks for 4 cycles, or paclitaxel (80 mg/m2 1-hour infusion) weekly for 12 weeks.
Publication Title
Biomarker analysis of neoadjuvant doxorubicin/cyclophosphamide followed by ixabepilone or Paclitaxel in early-stage breast cancer.

Description
The behavior of breast cancers and their response to neoadjuvant systemic therapy depend on their phenotype which is to a large extent determined by gene expression programs within the cancer cell.
Publication Title
Gene expression, molecular class changes, and pathway analysis after neoadjuvant systemic therapy for breast cancer.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
The cancer stem cell model maintains that tumors are organized in a hierarchy driven by tumor initiating cells (TICs), and that patient survival inversely correlates with TIC gene expression. Here we generated a prognostic signature for HER2+ breast cancer from TICs purified from MMTV-Her2/Neu mammary tumors. TICs from this model, identified as Lin-:CD24+:JAG1- at a frequency of 2-5% by serial and single cell transplantation assays, showed elevated expression of proliferation genes and low expression of differentiation genes (compared to non-TIC fraction CD24- of the same tumor).
Publication Title
Seventeen-gene signature from enriched Her2/Neu mammary tumor-initiating cells predicts clinical outcome for human HER2+:ERα- breast cancer.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Tumor samples were obtained from patients with stage II-III breast cancer before starting neoadjuvant chemotherapy with four cycles of 5-fluorouracil/epirubicin/cyclophosphamide (FEC) followed by four cycles of docetaxel/capecitabine (TX) on US Oncology clinical trial 02-103. Most patients with HER-2-positive cancer also received trastuzumab (H).

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
We identified tazarotene-induced gene 1 (TIG1) as a potential tumorigenic gene in IBC. To investigate the underlying mechanism by which TIG1 promotes tumor growth and invasiveness of IBC cells, we first sought to identify TIG1 functional partners by using DNA microarray analysis to compare gene expression profiles between SUM149 cells transfected with control siRNA and SUM149 cells transfected with siRNA targeting TIG1. We identified receptor tyrosine kinase Axl as a functional partner of TIG1.
Publication Title
TIG1 promotes the development and progression of inflammatory breast cancer through activation of Axl kinase.

Description
Current prognostic gene expression profiles for breast cancer mainly reflect proliferation status and are most useful in ER-positive cancers. Triple-negative breast cancers (TNBCs) are clinically heterogeneous, and prognostic markers and biology-based therapies are needed to better treat this disease.
Publication Title
A clinically relevant gene signature in triple negative and basal-like breast cancer.

Description
This is a stage-matched case control study. Cases with clinical diagnosis of Inflammatory Breast Cancer (IBC) were selected after reviewing all medical records of the 440 FNA samples. IBC was defined as signs of erythema and edema (peau dorange) involving at least one third of the skin and rapid clinical presentation. Presence of tumor emboli in the dermal lymphatics of the involved skin in the pathology report was not required for inclusion as IBC. Controls were selected to match for T stage, all T4a-c tumors in the data set were included as controls. IBC breast cancer are all T4d breast cancer.
Publication Title
Different gene expressions are associated with the different molecular subtypes of inflammatory breast cancer.
