TranscriptomicsTranscription profiling of human MCF7 cells following short-term E deprivation, ER-alpha siRNA knockdown and oxidant treatments
To investigate the oxidant sensitivity of E/ER regulated gene expression, E/ER regulated genes are identified using E deprivation or; ER-alpha siRNA knockdown; and oxidative stress responsive is determined by 8hr exposure to diamide, hydrogen peroxide and menadione Experiment Overall Design: MCF7 ce...

TranscriptomicsTranscription profiling of human age-dichotomized ER+, N0 breast tumors reveals enhanced NF kappa B and AP-1 activity associated with antiestrogen resistant breast caner
Signaling pathways that converge on two different transcription factor complexes, NFκB and AP-1, have been identified in estrogen receptor (ER)-positive breast cancers resistant to the antiestrogen, tamoxifen. In this study, biomarkers co-ordinately up-regulated by NFKB and AP-1 with prognositic si...

TranscriptomicsTranscription profiling of human age-dichotomized ER+ breast tumors
To investigate the biological basis between aging and sporadic breast cancer incidence and prognosis, RNA samples from matched ER+ invasive breast cancers diagnosed in either young (â?¤45) or old (â?¥70) women were analyzed by expression microarrays Experiment Overall Design: ER+ breast cancers coll...

TranscriptomicsReal-time quantitative PCR analysis of hormone-receptor-negative primary breast tumors
Total RNA was extracted from FFPE samples of 139 chemotherapy-naïve hormone-receptor-negative breast cancers pooled from three sample sources and assayed for the expression of 21 genes within two previously reported microarray-derived prognostic signatures in 6 RT-PCR multiplexes. RT-PCR gene expre...

TranscriptomicsFOXM1 Cistrome Predicts Breast Cancer Metastatic Outcome Better Than FOXM1 Expression Levels or Tumor Proliferation Index [RNA-Seq]
FOXM1 is a key transcription factor regulating cell cycle progression, DNA damage response, and a host of other hallmark cancer features, but the role of the FOXM1 cistrome in driving estrogen receptor-positive (ER+) vs. ER- breast cancer clinical outcomes remains undefined. Chromatin immunoprecipit...

TranscriptomicsSerial gene expression analysis in locally advanced breast cancer patients who failed to respond to neoadjuvant chemotherapy
To elucidate candidate genes and pathways associated with poor response, we retrospectively analyzed gene expression profiles in serial biopsies from women with locally advanced breast cancer who failed to respond to anthracycline-based chemo followed by taxane in the I-SPY Of the 221 patients who c...

Proteomics,MultiomicsIntegrative proteogenomic characterization of colorectal cancer cell lines and primary tumors
Solid tumors are complex organs comprising neoplastic cells and stroma, yet cancer cell lines remain widely used to study tumor biology, biomarkers and experimental therapy. Here, we performed a fully integrative analysis of global proteomic data comparing human colorectal cancer (CRC) cell lines to...
