Illumina MouseWG-6 v2.0 expression beadchip
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
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

Description
Though it is well established that immunological functions of CD4+ T cells are time of day-dependent, the underlying molecular mechanisms remain largely obscure. To address the question whether T cells themselves harbor a functional clock driving circadian rhythms of immune function, we analyzed clock gene expression and immune responses of CD4+ T cells purified from blood of healthy subjects at different time points throughout the day. Circadian clock function as well as immune function was further analyzed in cultivated T cells and circadian clock reporter systems. We found robust rhythms of clock gene expression as well as, after stimulation, of IFN-g production and CD40L expression in both freshly isolated and in cultured CD4+ T cells. Moreover, circadian luciferase reporter activities in CD4+ T cells and in thymic sections from PER2::LUCIFERASE reporter mice suggest that endogenous T cell clock rhythms are self-sustained under constant culture conditions. Microarray analysis of stimulated CD4+ T cell cultures revealed a rhythmic regulation of the NF-kB pathway as a candidate mechanism regulating circadian immune responses. Collectively, these data demonstrate for the first time that CD4+ T cell responses are regulated by an intrinsic cellular circadian oscillator capable of driving rhythmic adaptive immune responses in vitro and in vivo.

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.

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.
Publication Title
Dynamic EBF1 occupancy directs sequential epigenetic and transcriptional events in B-cell programming.

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.
