Arabidopsis Gene 1.1 ST Array (aragene11st)
Description
The effect of the overexpression of a stabilized version of the transcription factor RELATED TO APETALA2.12 (RAP2.12) on the transcriptome of Arabidopsis rosettes was investigated. To this purpose, 4-week old rosette of wild-type and 35S:13RAP2.12 plants were compared. Samples were composed of pools of 3 plants.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
HRE1 and HRE2 are two ERF transcription factors induced by low oxygen. In this work we analyzed the effect of ectopic expression of HRE1 and HRE2 on the arabidopsis transcriptome in aerobic and hypoxic (1% O2) conditions. While HRE1 has a moderate effect on the expression of anaerobic genes under hypoxia, HRE2 does not affect them either under aerobic or hypoxic conditions.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
This study analyzes transcriptomic data of Arabidopsis thaliana Col-0 and overexpression lines of Hypoxia Response Attenuator (HRA1; At3g10040) with Col-0 background (OE-HRA1). Two independent transgenic lines of OE-HRA1 were considered as biological replicates (OE-HRA1#1 and OE-HRA1#2). Seven-day-old seedlings were treated either with or without hypoxia (low oxygen) stress for 2 hours. This dataset includes CEL files, RMA signal values and MAS5 P/M/A calls from total mRNA populations. Quantitative profiling of cellular mRNAs was accomplished with the Affymetrix ATH1 platform.

- Affymetrix Rice Genome Array (rice)
Description
Rice (Oryza sativa L.) seeds can germinate in complete absence of oxygen. Under anoxia, the rice coleoptile elongates, reaching a length greater than that of the aerobic one. In this series, we compare the transcriptome of rice coleoptiles grown under aerobic and anaerobic conditions.
Publication Title

Description
The effect of the overexpression of Plant Cysteine Oxidase (PDCO1) on the transcriptome of Arabidopsis resettes was investigated with plants subjected to a 4h hypoxia (5% O2 v/v in air). For this purpose, 4-week old rosette of wild-type and 35S:FLAG:CDO1 plants were compared. Samples were composed of pools of 5 plants.

Illumina HiSeq 1500
Description
Floodings already have a nearly 60% share in the worldwide damage to crops provoked by natural disasters. Climate change will cause plants to be even more frequently exposed to oxygen limiting conditions (hypoxia) in the near future due to heavy precipitation and concomitant waterlogging or flooding events in large areas of the world. Although the homeostatic regulation of adaptive responses to low oxygen stress in plants is well described, it remained unknown by which initial trigger the molecular response to low-oxygen stress is activated. Here, we show that a hypoxia-induced decline of the ATP level of the cell reduces LONG-CHAIN ACYL-COA SYNTHETASE (LACS) activity, which leads to a shift in the composition of the acyl-CoA pool. High oleoyl-CoA levels release the transcription factor RELATED TO APETALA 2.12 (RAP2.12) from its interaction partner ACYL-COA BINDING PROTEIN (ACBP) at the plasma membrane to induce low oxygen-specific gene expression. We show that different acyl-CoAs provoke unique molecular responses revealing a novel role as cellular signalling component also in plants. In terms of hypoxia signalling, dynamic acyl-CoA levels integrate the cellular energy status into the oxygen signalling cascade with ACBP and RAP2.12 being the central hub. The conserved nature of the ACBP:RAP2.12 module in crops and the novel mechanistic understanding of how low-oxygen stress responses are initiated by oleoyl-CoA in plants provide useful leads for enhancing future food security. Overall design: 1 control and 3 treatments with different forms of acyl-CoA in triplicate biological replicates

Description
EMT, Epithelial to mesenchymal transition is a developmental biology process associated with migration, known to be involved in cancer metastasis. To study this process, we used the breast epithelial cell line MCF10A that enter in EMT after treatment with the cytokine TGFB or by expression of EMT transcriptor factor SNAIL. Overall design: mRNA profiles of MCF10A cells treated for 1 or 6 days with TGFb (done in duplicate), and mRNA profiles of Snail inducible line, MCF10A-SNAIl, induced for 1 or 6 days.
