Description
Identification of all genes expressed by mouse olfactory sensory neurons; genes expressed in mature neurons, immature neurons, or both were distinguished. Independent validation of enrichment ratio values supported by statistical assessment of error rates was used to build a database of statistical probabilities of the expression of all mRNAs detected in mature neurons, immature neurons, both types of neurons (shared), and the residual population of all other cell types.

In this study, we performed the gene expression analysis of the Normal, Diabetic and AAT treated NOD mice to elucidate the transcriptional changes induced by AAT. This will assist in identifying the biological processes / pathways involved in curative mechanism of AAT.

Description
The mechanisms involved in epithelium-stroma interactions remain poorly understood, despite the importance of the microenvironment during tumorigenesis. Here, we studied the role of Ets2 transcrpiton factor in tumor associated fibroblasts in the MMTV-ErbB2 mammary tumor model. Inactivation of Ets2 specifically in fibroblasts using Fsp-cre significantly reduced tumor growth, in contrast to Ets2 inactivation in epithelium in which no differences in tumor growth were observed.

Although the induction of C-FOS in the brain has been extensively studied for several decades to date there has been no attempt to identify the targets of C-FOS at a genome wide level, and it was not known how many genes C-FOS activates in a given cell. To identify potential C-FOS target genes, we performed microarray analysis on RNA obtained from mouse cortical (mCTX) neurons infected with lentivirus containing either a control shRNA (targeting firefly luciferase) or c-Fos shRNA that were subsequently depolarized with 0, 1, 3, or 6 hours of KCl.

Description
The tumor stroma is believed to contribute to some of the most malignant characteristics of epithelial tumors. However, signaling between stromal and tumor cells is complex and remains poorly understood. Here we show that genetic inactivation of Pten in stromal fibroblasts of mouse mammary glands accelerated the initiation, progression and malignant transformation of mammary epithelial tumors.

Description
The immense molecular diversity of neurons challenges our ability to deconvolve the relationship between the genetic and the cellular underpinnings of neuropsychiatric disorders. Hypocretin (orexin) containing neurons of the lateral hypothalamus are clearly essential for the normal regulation of sleep and wake behaviors, and have been implicated in feeding, anxiety, depression and reward. However, little is known about the molecular phenotypes of these cells, or the mechanism of their specification. We have generated a Hcrt bacTRAP line for comprehensive translational profiling of these neuronsin vivo. From this profile, we have identified 188 transcripts, as enriched in these neurons, in additions to thousands more moderately enriched or nominally expressed. We validated many of these at the RNA and protein level, including the transcription factor Lhx9. Lhx9 protein is found in a subset of these neurons, and ablation of these gene results in a 30% loss of Hcrt neuron number, and a profound hypersomnolence in mice.This data suggests that Lhx9 may be important for specification of some Hcrt neurons, and the subsets of these neurons may contribute to discrete sleep phenotypes.

Oocyte maturation is accompanied by a transition from mRNA stability to instability. We investigated the role of DCP1A and DCP2, proteins responsible for mRNA decapping, in mRNA destabilization during mouse oocyte maturation.

Description
REST is a master regulator of genes that are involved in the acqusition of neuronal fate. The role of REST is not well understood so we attempted to investigate the role of REST in the development of neural cells by analysing the genes that are upregulated when REST is knocked down via shRNA
Publication Title
REST regulates the pool size of the different neural lineages by restricting the generation of neurons and oligodendrocytes from neural stem/progenitor cells.

Description
Atherosclerosis and pressure overload are major risk factors for the development of heart failure in patients. Cardiac hypertrophy often precedes the development of heart failure. However, underlying mechanisms are incompletely understood. To investigate pathomechanisms underlying the transition from cardiac hypertrophy to heart failure we used experimental models of atherosclerosis- and pressure overload-induced cardiac hypertrophy and failure, i.e. apolipoprotein E (apoE)-deficient mice, which develop heart failure at an age of 18 months, and non-transgenic C57BL/6J (B6) mice with heart failure triggered by 6 months of pressure overload induced by abdominal aortic constriction (AAC). The development of heart failure was monitored by echocardiography, invasive hemodynamics and histology. The microarray gene expression study of cardiac genes was performed with heart tissue from failing hearts relative to hypertrophic and healthy heart tissue, respectively. The microarray study revealed that the onset of heart failure was accompanied by a strong up-regulation of cardiac lipid metabolism genes involved in fat synthesis, storage and oxidation.
