A number of studies find that metastasis suppressor proteins, including RhoGDI2, may function in part though controlling expression of genes regulating metastasis (reviewed in Smith and Theodorescu, Nature Reviews Cancer, 2009, PMID: 19242414). To uncover systematically gene expression patterns dependent on RhoGDI2 expression, we profiled gene expression in stably transfected control (GFP empty vector) UM-UC-3 bladder carcinoma cells (which have lost endogenous expression of RhoGDI2, as occurs commonly in the progression of bladder cancer PMID: 15173088), as well as stably transfected GFP-tagged RhoGDI2 expressing UM-UC-3 cells.
RhoGDI2 suppresses lung metastasis in mice by reducing tumor versican expression and macrophage infiltration.

View SamplesGiven the heterogeneity of disease evident from study of the presentation, histomorphology, disease course, and molecular lesions of bladder cancer, a cohort of 8 non-muscle invasive and 11 muscle invasive bladder cancers were profiled for gene expression using the Affymetrix HG-U133A platform.

View SamplesLoss of Amylo-alpha-1-6-glucosidase-4-alpha-glucanotransferase (AGL) drives bladder cancer growth. Low AGL expression predicts poor patient outcome. Currently no specific therapeutically tractable targets/pathways exist that could be used to treat patients with low AGL expressing bladder tumors.

View SamplesAdaptive immune responses to infection result in the formation of memory T cells that respond more rapidly and robustly to reinfections, providing the basis of the immunological memory targeted by vaccines. Underlying the enhanced responsiveness of memory cells is their ability to rapidly up-regulate the transcription of key effector genes at a higher level compared to nave cells (termed transcriptional memory). While transcriptionally permissive histone modifications are known to provide chromatin structures that facilitate transcriptional memory, the molecular mechanisms that underpin this process still remain elusive. Here we investigate the transcriptional response of the Jurkat T cell line to stimulation with PMA and Ionomycin and determine if this response differs in cells that have seen stimuli previously.

View SamplesPurpose: Despite advances in radical surgery and chemotherapy delivery, ovarian cancer is the most lethal gynecologic malignancy. Most of these patients are treated with platinum-based chemotherapies, but there is no biomarker model to guide their responses to these therapeutic agents. We have developed and independently tested our novel multivariate molecular predictors for forecasting patients' responses to individual drugs on a cohort of 58 ovarian cancer patients.

View SamplesWe report gene expression data for FACS sorted zebrafish mpeg1:mCherry + and mpx:EGFP + cells collected from whole embryos at 72 hours post fertilization (hpf). We also report gene expression data for the remaining, transgene negative, portion of these embryos. Overall design: ~1,000 mpeg1:mCherry+; mpx:EGFP+ transgenic embryos were homogenized, filtered, and sorted using FACS into PBS, collecting >50,000 cells for each of the three populations: mpeg1:mCherry+, mpx:EGFP+ and double negative (no double positive cells were collected as there was almost no overlap between mCherry and EGFP expression).
