Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Microarray analysis has been applied to the cell proliferation in a human colonic cel line, Caco-2. We have shown previously that a moderate riboflavin depletion around weaning has a profound impact on the structure and function of the small intestine of the rat, which is not reversible following riboflavin repletion. In this study we have modelled riboflavin deficiency in a human cell line, shown irreversible loss of cell viability associated with impaired mitosis and identified candidate effectors of riboflavin depletion in the cell.

- Affymetrix Murine Genome U74A Version 2 Array (mgu74av2), Affymetrix Mouse Expression 430A Array (moe430a)
Description
A microarray time series was generated to identify cyclic genes of the segmentation clock in the mouse. The right posterior half presomitic mesoderms (PSM) from 17 mouse embryos were dissected while the contralateral side of the embryo containing the left PSM was immediately fixed to be analyzed by in situ hybridization using a Lfng probe to order the samples along the segmentation clock oscillation cycle. Probes were produced from RNA extracted from the 17 dissected posterior half PSMs using a two-step amplification protocol and were hybridized to Affymetrix GeneChip MOE430A. The reproducibility of the amplification procedure was initially assessed by comparing array data generated from the right and the left posterior PSM from the same embryo. Because of the symmetry of the paraxial mesoderm along the left-right axis, left and right samples are expected to show overtly similar gene expression. RNA was amplified from three such sample pairs (1, a and b; 2, a and b; 3, a and b) and hybridized on Murine Genome U74Av2 array (MG-U74Av2)

Illumina HiSeq 2000
Description
We generated Gadd45a,b,g triple-knockout mouse embryonic stem cells and performed RNA-seq expression profiling under six different conditions of cell culture and in vitro differentiation. Overall design: Gadd45a,b,g triple knockout (TKO) mouse embryonic stem cells (mESC) were generated by CRISPR/Cas9. RNA-Seq was performed to compare the transcriptome in three independent Gadd45 TKO versus three independent control mESC lines under different conditions: (i) Serum cultured mESC, (ii) Vitamin C treated mESC, (iii) 2i treated mESC, (iv) mESC differentiated as embryoid bodies (EB), (v) mESC differentiated as a serum-free monolayer, and (vi) EB stimulated with retinoic acid (RA).

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The Sin3 histone deacetylase (HDAC) complex is a 1.2 MDa chromatin modifying complex that can repress transcription by binding to gene promoters and deacetylating histones. The Sin3/HDAC complex can affect cell cycle progression through multiple mechanisms and is among the targets of anticancer drugs, called HDAC inhibitors. We describe the identification of a new subunit of the Sin3 complex named family with sequence similarity 60 member A (FAM60A). We show that FAM60A/Sin3 complexes normally suppress the epithelial-to-mesenchymal transition (EMT) and cell migration. This occurs through transcriptional repression of genes that encode components of the TGF-beta signaling pathway. This work reveals that FAM60A and the Sin3 complex are upstream repressors of TGF-beta signaling, EMT and cell migration and extends the known biological roles of the Sin3 complex. This experiment investigates the role of FAM60A in gene expression by comparing A549 lung cancer cells treated with or without siRNA against FAM60A.

Description
We extracted nascent plasma cell tumor (PCT) cells from within inflammatory granulomas (OG) isolated from intraperitoneal pristane-injected BALB/c.iMyc E mice at five different time points during tumor progression. We used laser capture micro-dissection to collect incipient PCT cells and analyzed their global gene expression on Affymetrix Mouse Genome 430A microarrays. Two independent studies were performed with different sets of mice

Description
We characterized monosaccharide-dependent gene expression in the Drosophila fat body using fructose and glucose. Control and high-sugar diets were compared and RNA-seq was used to identify potential target genes. Overall design: Drosophila were reared on control (0.3 M fructose or glucose) or high sugar (1.7 M fructose or glucose) diets until the wandering third instar stage. Fat bodies were isolated and RNA was extracted to determine the effects of each sugar at different concentrations on gene expression using Illumina RNA-seq.

Description
We compared gene expression in the Drosophila fat body on control and high-sugar diets in order to gain insight into the role of this organ during caloric overload. Differential expression analysis revealed changes in gene expression suggestive of a role for CoA metabolism in the ability to tolerate high-sugar feeding. This led us to perform biochemical and mutant studies supporting a model where CoA is limiting in the face of caloric overload. Overall design: Wild-type Drosophila were reared on control (0.15M sucrose) and high-sugar (0.7M sucrose) diets until the wandering stage. Fat bodies were isolated and RNA extracted to determine the effects of diet on gene expression using Illumina RNA-seq.

CoA protects against the deleterious effects of caloric overload in Drosophila.
