Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
An Arabidopsis mutant showing an altered ability to green on illumination after extended periods of darkness has been isolated in a screen for genomes uncoupled (gun) mutants. Following illumination for 24 h, 10-day-old dark-grown mutant seedlings accumulated 5 times more chlorophyll than wild-type seedlings and this was correlated with differences in plastid morphology observed by transmission electron microscopy. The mutant has been named greening after extended darkness 1 (ged1). We used microarrays to detail the global profiles of transcript abundances in the mutant in comparison to the wild type. Microarray analysis showed much lower amounts of transcripts of genes encoding seed storage proteins, oleosins and late embryogenesis abundant (LEA) proteins in 7-day-old seedlings of ged1 compared to wild type. RNA-gel-blot analyses confirmed very low levels of transcripts of seed protein genes in ged1 seedlings grown for 2-10 days in the dark, and showed higher amounts of transcripts of photosynthesis-related genes in illuminated 10-day-old dark-grown ged1 seedlings compared to wild type.

Illumina HiSeq 2000
Description
Neural cell adhesion molecule 1 (NCAM1; also known as CD56) is expressed in up to 20% of acute myeloid leukemia (AML) patients. Expression of NCAM1 is widely used as a marker of minimal residual disease; however, the biological function of this cell surface protein in AML remains elusive. In this study we investigated the impact of aberrant NCAM1 expression on leukemogenesis, drug resistance and its role as a biomarker to guide therapy.Gene expression profiling was performed with RNA-seq in three cell lines (SKM-1, NOMO-1, MOLM-14) after doxycycline-mediated induction of scrambled shRNA or shNCAM1 at timepoint 72 hours. Overall design: mRNA profiles of cell lines SKM-1, NOMO-1, MOLM-14 transfected either with scrambled shRNA or shRNA-NCAM1 were generated using TruSeq RNA Library Prep Kit v2 (Illumina) followed by sequencing with 100 bp paired-end reads on HiSeq 2000.

Description
Comparison of the transcriptome of human kideny cancer cells either wild-type for FH or FH-deficient. The UOK262 cells were isolated from mediastinum metastasis of a HLRCC patient (Yang et al. Cancer Genetics and Cytogenetics, Volume 196, Issue 1, 1 January 2010, Pages 45–55). FH function was restored in the UOK262 by re-expressing the FH transcript from an exogenous plasmid. Overall design: Examination of gene transciption in 2 cell types.

Description
Comparison of the transcriptome of immortalised mouse kidney epithelial cells either wt for Fh1 or Fh1-deficient. The cells were isolated from kidneys of P5 mouse(see Frezza et al, Nature 2011). Briefly, Fh1_fl (flox) are wt for Fh1 (floxed cassette not excised), clone 1 and clone 19 are two different Fh1-deificent clones (floxed cassette excised) and Rec are clone 19 with reconstituted Fh1 expression from exogenous plasmid. Overall design: Examination of gene transciption in 4 cell types.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
A number of studies find that metastasis suppressor proteins, including RhoGDI2, may function in part though controlling expression of genes regulating metastasis (reviewed in Smith and Theodorescu, Nature Reviews Cancer, 2009, PMID: 19242414). To uncover systematically gene expression patterns dependent on RhoGDI2 expression, we profiled gene expression in stably transfected control (GFP empty vector) UM-UC-3 bladder carcinoma cells (which have lost endogenous expression of RhoGDI2, as occurs commonly in the progression of bladder cancer PMID: 15173088), as well as stably transfected GFP-tagged RhoGDI2 expressing UM-UC-3 cells.

Description
Approximately 2.5 mg dry Col-0 seedlings were surface sterilized and stratified for 2 days at 4degreesC in liquid media containing 1.5% sucrose (w/v) before being transferred to light with constant shaking at 100 rpm on an orbital shaker. After 7 days, the seedling clusters were subjected to the treatments for 1 hr followed by total RNA isolation using the RNAqueous kit (Ambion). Each treatment was performed in triplicate or quadruplicate. All labeling (Enzo) and hybridization (Affymetrix) procedures were performed as directed by the manufacturers. Raw probe intensities output by the Affymetrix MAS software were processed using the RMA algorithm to obtain an expression measure for each gene on each array.
