Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Glucose intolerance and diabetes mellitus are classical parts of endogenous Cushings syndrome (CS), and insulin resistance is a feature of cortisol excess. CS patients display characteristics including hyperglycemia, abdominal obesity, reduced high-density lipoprotein cholesterol levels and elevated triglycerides, and arterial hypertension. Hypercortisolism is a well known cause of bone loss, and patients with CS frequently display low bone mass and fragility fractures. Cortisol excess inhibits bone formation, increases bone resorption, impairs calcium absorption from the gut, and affects the secretion of several hormones, cytokines, and growth factors with potential influence on bone metabolism. Bone biopsies from nine CS patients, before and mean 3 months after surgery, were screened for expressional candidate genes using Affymetrix human Gene Plus 2.0 Arrays. Analyses were performed to identify genes in glucocorticoid-induced osteoporosis and genes in glucose metabolism and energy homeostasis.
Publication Title
The glucocorticoid-induced leucine zipper gene (GILZ) expression decreases after successful treatment of patients with endogenous Cushing's syndrome and may play a role in glucocorticoid-induced osteoporosis.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
We performed a microarray experiment to assess the global changes in transcription occurring in leaves and roots of the vitamin B6 deficient pdx1.3 knockout mutant in comparison to WT. Vitamin B6 (pyridoxal 5-phosphate) is an essential cofactor of many metabolic enzymes. Plants biosynthesize the vitamin de novo employing two enzymes, pyridoxine synthase1 (PDX1) and PDX2. In Arabidopsis (Arabidopsis thaliana), there are two catalytically active paralogs of PDX1 (PDX1.1 and PDX1.3) producing the vitamin at comparable rates. Since single mutants are viable but the pdx1.1 pdx1.3 double mutant is lethal, the corresponding enzymes seem redundant.
Publication Title
Consequences of a deficit in vitamin B6 biosynthesis de novo for hormone homeostasis and root development in Arabidopsis.

Illumina HiSeq 2500
Description
EBF1 is essential for B cell specification and commitment. To explore the dynamics of EBF1 initiated B cell programming, we performed EBF1 ChIP-seq, ATAC-seq, bisulfite-seq, RNA-seq and several histone ChIP-seq analyses at different stages of the transition from Ebf1-/- pre-pro-B to pro-B triggered by EBF1 restoration. We also performed Pax5 ChIP-seq in Ebf1-/- pre-pro-B cell and EBF1-restored pro-B cell to study the pioneering function of EBF1 that allows other transcription factors to access certain chromatin sites. Overall design: Time series RNA-Seq analysis during the differentiation from Ebf1-deficient pre-pro-B cell to EBF1-restored pro-B cell.

Description
Chronic loss of Lasp1 alters the expression of other genes associated with cell motility/attachment, and/or other cellular functions. Results provide new information showing that loss of Lasp1 leads to up- and down-regulation of genes involved in cell motility/attachment/growth.
Publication Title
Lasp1 gene disruption is linked to enhanced cell migration and tumor formation.

Description
To study the role Cnot3 in early B cells development, RNASeq analysis of pro-B cells (B220+ and CD43+) was performed in tamoxifen treated Cnot3(fl/fl) RERTCre and Cnot3+/+;RERTCre mice. Overall design: Two individual replicates of Cnot3(fl/fl) RERTCre and Cnot3(+/+) RERTCre mice were tamoxifen treated periodically. Ten days after the initial treatment, B220+CD43+ pro-B cells were sorted from the bone marrow and RNASeq analysis was performed.

Oral cancer kills about 1 person every hour each day in the United States and is the 6th most prevalent cancer worldwide. In this study we utilized existing microarray data from a prior oral cancer study to examine the role of chronic pro-inflammatory mediators in oral carcionogenesis by comparing gene expression in oral tumors with adjacent non-tumor oral tissue from the same patient
