Affymetrix Vitis vinifera (Grape) Genome Array (vitisvinifera)
Description
Oxidative stress can arise when in vitro propagated plants developed under low light conditions are exposed to high light during transfer to ex vitro conditions. In such a situation, among the many potential stresses to which the transferred plant can be exposed, oxidative stress is commonly experienced, most likely brought about by absorption of light energy in excess of that required for very low levels of photosynthetic metabolism. In vitro propagated grapevine when transferred to ex vitro conditions with a 4 fold increase in PPFD shows an initial inhibition of PET accompanied by an accumulation of H2O2, suggesting a signal for the upregulation in gene expression and antioxidant enzyme activity, which peaked at 48h after transfer of in vitro grapevine to ex vitro growing conditions.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Substantia nigra pars compacta (SNpc) is highly sensitive to normal aging and selectively degenerates in Parkinson's disease. However, ventral tegmental area (VTA), a region adjacent to SNpc, is less affected in PD. Until now, molecular mechanisms behind VTA aging have not been fully investigated using high throughput techniques.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Growth of the drosophila eye imaginal discs is controlled by the activation of Notch in the dorsal-ventral boundary. Overexpression in the eye disc of the Notch ligand Delta together with lola and pipsqueak from the GS(2)88A8 line induces tumoral growth. We used microarray to analyze the expression profile of tumoral discs.
Publication Title
Imaginal discs secrete insulin-like peptide 8 to mediate plasticity of growth and maturation.

Description
A toxicogenomic analysis from liver of different pharmacological active coumarins (mammea A/BA+A/BB 3:1 and soulatrolide ) was performed on mice treated (20mg/kg/daily) for a whole week to evaluate if such compounds possess or could develop a hazardous profile on liver.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
This study focus a comparative toxicogenomic analysis of the effects of four herbicides (alachlor, ALA, S-metolachlor, S-MET, diuron, DIU, and MCPA-methyl ester, MCPA-ME), one insecticide (carbofuran, CAB), and one fungicide (pyrimethanil, PYR), in the model yeast Saccharomyces cerevisiae, to predict potential cytotoxic effects of these xenobiotics while providing mechanistic clues possibly relevant for experimentally less accessible non-target eukaryotes. The six model pesticides selected have been used worldwide in agricultural activities, at the present time or in the past, and have different modes of action on their target-organisms. Moreover, some of them are currently in Annex 1 of EC Directive 1107/2009 (repealing 91/414), that is they are in use in the EU, but having some ecotoxicological concerns (e.g. S-MET, PYR, MCPA-ME), others have their use restricted and/or are priority substances under the Water Framework Directive (e.g. ALA, DIU), and one was banned (e.g. CAB).
