Project description:We performed RNAi knockdown experiments on 7 different signal transduction components of the Wnt pathway in HCT116 colon cancer cells and prepared RNA libraries from the poly-adenylated fraction of the RNA. SOLiD sequencing of strand-specific, barcoded transcriptome libraries yielded expression profiles allowing us to extract common pathway signatures and enabeling us to perform susequent nested effects modelling. the resulting pathway models yields new insight in the pathway topology in colon cancer.

Project description:Several recent studies, including ours, show that most components of signal transduction cascades including the extracellular signal-regulated protein kinase (ERK), that once were thought to act predominantly in cytoplasm, are in fact recruited to chromatin and are integral components of transcriptional complexes. However, their distribution along whole genome remains uncovered. Here we investigate genome wide recruitment of the ERK pathway components using chromatin immunoprecipitations (ChIP) followed by deep sequencing, ChIP-Seq.

Project description:Sucrose is the major product of photosynthesis in many higher plants. It is transported from the source tissue through the phloem to various sink tissues to support plant growth, development and reproduction. Knowledge of the signal transduction pathways involved in carbohydrate metabolism is limited. Genes involved in the regulation of sucrose synthesis and accumulation could be used as tools in the development of genetically manipulated plants with higher sucrose content or aid in breeding programs as molecular markers. Using the SUCEST (Sugarcane EST) database information and a microarray approach, the expression profiles of 1920 sugarcane (Saccharum spp.) genes encoding signal transduction elements, transcription factors and stress-related proteins were analyzed. In order to assess their involvement in sucrose metabolism, the expression profiles of individuals from a sugarcane population segregated for sugar content were compared. From a population of 500 F1 individuals, the seven with the highest and the seven with the lowest sugar contents were selected, pooled and profiled using cDNA microarrays. Twenty-four genes were identified as differentially expressed. Five of them were more expressed in the plants with the highest sugar contents and 19 in the plants with the lowest sugar contents. RNA-blot hybridization was used to validate the expression profiles obtained for individuals in each group. These genes were shown to have differential expression throughout the growing season and in the different tissues. Our data supports the view that sugar levels modulate a complex signal transduction network that seems to involve responses related to stress. Keywords: Segregated population

Hela-S3 cells were starved for 48 hours (control) and stimulated with EGF at concentration of 100ng/mL for 20 minutes. Cells were fixed with formaldehyde, chromatin isolated and subjected to ChIP reaction. Two technical replicates of ChIP reaction followed by sequencing were performed.

Project description:We have previously demonstrated that molecular hydrogen (H2) neutralizes hydroxyl radical (•OH) in cultured-cells and protects cells and tissues against oxidative stress. Growing evidence has confirmed that H2-consumption exhibits preventive and therapeutic effects in patients with various diseases as well as model animals. Moreover, a small amount of H2 modulates signal transduction for regulating the expression of various genes; however, the primary target of H2 for exhibiting a variety of phenotypes was completely unknown. Here we show that H2 at low amounts manipulates oxidized phospholipid mediators to modulate Ca2+-signal transduction and gene expression.
