Description
Cancer cells alter their metabolism to support their malignant properties. By transcriptomic analysis we identified the glucose-transforming polyol pathway (PP) gene aldo-keto-reductase-1-member-B1 (AKR1B1) as strongly correlated with epithelial-to-mesenchymal transition (EMT). This association was confirmed staining samples from lung cancer patients and from an EMT-driven colon cancer mouse model with p53 deletion. In vitro, mesenchymal-like cancer cells showed increased AKR1B1 levels and AKR1B1 knockdown was sufficient to revert EMT. An equivalent level of EMT suppression was measured by targeting the downstream enzyme sorbitol-dehydrogenase (SORD), further pointing at the involvement of the PP. Comparative RNA sequencing profiling confirmed a profound alteration of EMT in PP-deficient cells, revealing a strong repression of TGF-Beta signature genes. Mechanistically, excess glucose was found to promote EMT through autocrine TGF-Beta stimulation, while PP-deficient cells were refractory to glucose-induced EMT. PP represents a molecular link between glucose metabolism and cancer differentiation and aggressiveness, and a novel potential therapeutic target. Overall design: 3x3 biological replicated samples; 2 groups of samples with shRNA-mediated specific gene inhibition and scrambled control cells

Description
Rationale: Lipopolysaccharide (LPS) is ubiquitous in the environment. Inhalation of LPS has been implicated in the pathogenesis and/or severity of several lung diseases, including pneumonia, chronic obstructive pulmonary disease and asthma. Alveolar macrophages are the main resident leukocytes exposed to inhaled antigens. Objectives: To obtain insight into which innate immune pathways become activated within human alveolar macrophages upon exposure to LPS in vivo.
Publication Title
Gene expression profiles in alveolar macrophages induced by lipopolysaccharide in humans.

Description
During the course of adjuvant arthritis, maximal changes in gene expression were observed at the incubation phase. A major group of genes affected was related to immune activity. Tolerance induction by mycobacterial heat-shock protein 65 (Bhsp65), the disease-related antigen, caused upregulation of a large number of genes. These included immune activity genes as well as cell proliferation-related genes.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
We compared the seedling transcription profiles to determine the effects of loss-of-function of the BRX gene of Arabidopsis. BRX is required for optimal root growth. We compared seedlings of a loss-of-function line (brx) with its control background (Sav-0). Because the loss-of-function line was derived from introgression, a brx line that was complemented by a transgenic wild type copy of BRX was also included as a control. This line (rescued brx) allows the identification of expression differences that are due to introgression drag. See Mouchel et al. 2004, Genes & Dev. Vol. 18, p. 700 for a detailed description. We also compared to response of the different genotypes to the application of the phytohormones brassinolide (BL) and indole acetic acid (IAA)
