- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
The heat shock response continues to be layered with additional complexity as interactions and cross-talk among heat shock proteins, the reactive oxygen network and hormonal signaling are discovered. However, comparative analyses exploring variation in each of these processes among species remains relatively unexplored. In controlled environment experiments, photosynthetic response curves were conducted from 22 C to 42 C and indicated that temperature optimum of light saturated photosynthesis was greater for Glycine max relative to Arabidopsis thaliana or Populus trichocarpa. Transcript profiles were taken at defined states along the temperature response curves and inferred pathway analysis revealed species-specific variation in the abiotic stress and the minor carbohydrate raffinose/galactinol pathways. A weighted gene co-expression network approach was used to group individual genes into network modules linking biochemical measures of the antioxidant system to leaf-level photosynthesis among P. trichocarpa, G. max and A. thaliana. Network enabled results revealed an expansion in the G. max HSP17 protein family and divergence in the regulation of the antioxidant and heat shock module relative to P. trichocarpa and A. thaliana. These results indicate that although the heat shock response is highly conserved, there is considerable species-specific variation in its regulation.

Description
Cellular responses to carcinogens are typically studied in transformed cell lines, which do not reflect the physiological status of normal tissues. To address this question, we have characterized the transcriptional program and cellular responses of normal human lung WI-38 fibroblasts upon exposure to the ultimate carcinogen benzo[a]pyrene diol epoxide (BPDE). Exposure to BPDE induces a strong inflammatory response in WI-38 primary fibroblasts. Whole-genome microarray analysis shows induction of several genes related to the production of inflammatory factors, including those that encode interleukins (ILs), growth factors, and enzymes related to prostaglandin synthesis and signaling. This is the first demonstration that a strong inflammatory response is triggered in primary fibroblasts in response to a reactive diol epoxide derived from a polycyclic aromatic hydrocarbon.

Description
Gold is widely considered to be a biologically inert element; however, it can elicit a profound biological response in plants. Plants can be exposed to significant levels of this precious metal in the environment from naturally occurring sources, as the result of mining activities or more recently resulting from the escalating use of nanoparticles in industry. In this microarray study we have investigated the gene expression response of Arabidopsis thaliana (Arabidopsis) to gold. Although the uptake of metal cations by plant transporters is well characterised, little is known about the uptake of gold, which exists in soil predominantly in a zero-valent state (Au0). We used this study to monitor the expression of candidate genes involved in metal uptake and transport. These show the down-regulation of a discreet number of genes known to be involved in the transport of copper, cadmium, nickel and iron.
