Description
Stem-cells and transformed cancer cells specifically express a polycomb repressive complex subtype, PRC4 which characteristically contains Sirt1 (Sirtuin-1), a NAD+ dependent class III histone deacetylase (HDAC) and Eed2 isoform as specific members. Analyzing the transcriptiome and methylome analysis of Sirt1 deficient murine ESCs (Sirt1-/- ESC), we demonstrate that these cells repressed specifically on some genomic imprinted and germ-line related genes.

Description
A control vs. genetic knockout experiment aimed at determining what RNAs are upregulated or downregulated in e11.5 mouse proximal limb tissue lacking the Lmx1b gene. Because Lmx1b is required for dorsal-ventral patterning of the limb, this screen gives insight into what putative downstream targets of Lmx1b contribute to dorsal-ventral patterning.
Publication Title
Identification of genes controlled by LMX1B in the developing mouse limb bud.

Description
The fidelity of sound transmission by cochlear implants in patients with sensorineural hearing loss could be greatly improved by increasing the number of frequency channels. This could be achieved by stimulating and guiding neurite outgrowth to reduce the distance between the implant's electrodes and the remnants of the spiral ganglion neurons. However, little is known about signaling pathways, besides those of neurotrophic factors, that are operational in the adult spiral ganglion. To systematically identify neuronal receptors for guidance cues in the adult cochlea, we conducted a genome-wide cDNA microarray screen with two-month-old CBA/CaJ mice. A meta-analysis of our data and those from older mice in two other studies revealed the presence of neuronal transmembrane receptors that represent all four established guidance pathwaysephrin, netrin, semaphorin, and slitin the mature cochlea as late as 15 months. In addition, we observed the expression of all known receptors for the Wnt morphogens, whose neuronal guidance function has only recently been recognized. In situ hybridizations located the mRNAs of the Wnt receptors frizzled 1, 4, 6, 9, and 10 specifically in adult spiral ganglion neurons. Finally, frizzled 9 protein was found in the growth cones of adult spiral ganglion neurons that were regenerating neurites in culture. We conclude from our results that adult spiral ganglion neurons are poised to respond to neurite damage, owing to the constitutive expression of a large and diverse collection of guidance receptors. Wnt signaling, in particular, emerges as a candidate pathway for guiding neurite outgrowth towards a cochlear implant after sensorineural hearing loss.

Description
Resiquimod is a nucleoside analog belonging to the imidazoquinoline family of compounds which is known to signal through Toll-like receptor 7. Resiquimod treatment has been demonstrated to inhibit the development of allergen induced asthma in experimental models. Despite this demonstrated effectiveness, little is known about the molecular events responsible for this effect. The aim of the present study was to elucidate the molecular processes which were altered following resiquimod treatment and antigen challenge in a mouse model of allergic asthma. Employing microarray analysis, we have characterized the asthmatic transcriptome of the murine lung and determined that it includes genes involved in: the control of cell cycle progression, airway remodelling, the complement and coagulation cascades, and chemokine signalling. We have demonstrated that systemic resiquimod administration resulted in the recruitment of NK cells to the lungs of the mice, although no causal relationship between NK cell recruitment and treatment efficacy was found. Furthermore, results of our studies demonstrated that resiquimod treatment resulted in the normalization of the expression of genes involved with airway remodelling and chemokine signalling, and in the modulation of the expression of genes including cytokines and chemokines, adhesion molecules, and B-cell related genes, involved in several aspects of immune function and antigen presentation. Overall, our findings identified several genes, important in the development of asthma pathology, that were normalized following resiquimod treatment thus improving our understanding of the molecular consequences of resiquimod treatment in the lung milieu.

Description
Stat5+/- mice were bred into the C57BL/6 background. Stat5+/- mice were intercrossed and mouse embryonic fibroblasts (MEFs) were isolated from 12.5-13.5-day WT or Stat5-/- fetuses. The retroviral-expression vector carrying a wild-type Stat5A gene based on an MSCV-IRES-GFP backbone (gift from Richard Moriggl, Ludwig-Boltzmann Institute, Vienna, Austria) was infected into Stat5-/- MEFs. FACS was used to select GFP+ cells. After 5 hours starvation in serum free medium with 0.1% of BSA, MEFs were treated with growth hormone for 2 hours. Total cellular RNA from each group of the MEFs was extracted with TRIzol reagent (Invitrogen) according to the manufacturer's instructions. Microarray analyses were performed using Affymetrix Mouse Genome 430 2.0 GeneChips (Affymetrix, Santa Clara, CA) (six groups, biological replicates for each group). Expression values were determined with GeneChip Operating Software (GCOS) v1.1.1 software. RMA signals were summarized using GeneSpring GX 10.0.1 (Agilent) and normalized by quantile normalization. All data analysis was performed with GeneSpring software GX 10.01.
