- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Understanding how developmental and environmental signals are integrated to produce specific responses is one of the main challenges of modern biology. Hormones and, most importantly, interactions between different hormones serve as crucial regulators of plant growth and development, playing central roles in the coordination of internal developmental processes with the environment. Herein, a combination of physiological, genetic, cellular, and whole-genome expression profiling approaches has been employed to investigate the mechanisms of interaction between two key plant hormones, ethylene and auxin.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
ACC Synthase (ACS) is the key regulatory enzyme in the ethylene biosynthesis in plants. It catalyzes the conversion of s-adenosylmethionine (SAM) to 1-aminocyclopropane-1-carboxylic acid (ACC), the precursor of ethylene. Arabidopsis has nine ACS genes. The goal of the project is to inactivate each gene by insertional mutagenesis and amiRNA technology and eventually construct a null ACS mutant. We have been recently able to achieve this goal. Furthermore, we wanted to know how inactivation of individual ACS genes affects global gene expression.

Description
Satellite cells are the primary source of stem cells for skeletal muscle growth and regeneration. Since adult stem cell maintenance involves a fine balance between intrinsic and extrinsic mechanisms, we performed genome-wide chronological expression profiling to identify the transcriptomic changes involved during early postnatal growth till acquisition of satellite cell quiescence.

- Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
Wild-type and mouse mutants for FGF3, FGF10 and FGF3/FGF10 double mutants at embryonic day E10 were analysed by microarrays for downregulated genes. A tissue sample corresponding to an area containing the otic vesicle and surrounding mesenchyme and neighboring hindbrain were isolated from E10 embryos (See Figure 3A of manuscript). Five samples were pooled for RNA preparation. Samples were isolated from wild-type, FGF3, FGF10 and FGF3/FGF10 double mutants. Two RNA samples for each genotype were generated (corresponding to 8 tissue samples). RNA was labeled and hybridized with Affymetrix U74A V2 arrays.

Illumina HiSeq 2000
Description
Purpose: The goal of this study is to compare the transcriptome profilling (RNA-seq) of inflorescences infected with tobacco ratle virus (TRV) to mock inoculated inflorescences (negative controls), in Arabidopsis plants Methods: Inflorescences of systemically TRV infected or mock-inoculated plants were collected from more than 40 independent Arabidopsis plants, at 14 days post-inoculation (dpi). TRV and mock mRNA profiles were generated by deep sequencing by Illumina HiSeq 2000. The sequence reads that passed quality filters (SOAPnuke) were analysed by Burrows-Wheeler (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. Genes and isoforms were quantified by RSEM sofware package. qRT-PCR validation was performed using TaqMan and SYBR Green assays. Results: Here we report a significant repression of DNA methylation genes in inflorescences of Arabidopsis plants infected with Tobacco rattle virus (TRV) that coincides with dynamic changes in methylation at the whole genome level. Arabidopsis mutants deficient in DNA methylation were more resistant to this virus in early colonized tissues but more susceptible at later time points of infection, indicating that DNA methylation was critical to control both proliferation and antiviral defense. We found that TRV interference with DNA methylation leads to changes in the methylation and trancriptional status of transposable elements (TEs), including TEs located in the promoter of disease resistance genes that were significantly repressed in plants exposed to TRV. Activation of both TEs and their nearby disease resistance genes was altered in a range of hypo- and hyper-methylated Arabidopsis mutants, indicating that perturbations in DNA methylation contributes to modulate their expression in infected plants. Conclussion: Our study showed that TRV interferes with DNA methylation to alter the transcriptional silencing of TEs, which in turn compromises the expression of neighboring disease resistance genes. Overall design: TRV and mock mRNA profiles were generated from Arabidopsis inflorescences by deep sequencing with Illumina HiSeq 2000.

Description
We report the RNAseq analysis of human dermal fibroblasts which have been treated by protocols to stimulate their differentiation towards the otic lineage. This was achieved by transfection with different transcription factors with the aim to induce an initial reprogramming of the cells and was followed by growth factor treatments known to promote otic differentiation. The results show that a partial differentiation towards the otic lineage is achieved by these protocols. Overall design: RNAseq profiles were obtained from human dermal fibroblasts with two different protocols. Prior to treatment with growth factors stimulating differentiation, the samples were either transfected with the transcription factors OCT4 or a combination of ATOH1, POU4F3 and GFI1.
