Description
Primary murine osteoblasts were isolated form the calvariae of newborn mice. 10 days after the addition of ascorbic acid (50 g/ml) and -glycerophosphate (10 mM), cells were serum-starved over night and then incubated for 6 hours with condtioned medium of MDA-PCa2b cells or conditioned medium of PC-3 cells

Description
To identify the activity-induced gene expression programs in inhibitory and excitatory neurons, we analyzed RNA extracted from cultured E14 mouse MGE- and CTX-derived neurons (DIV 10) after these cultures were membrane-depolarized for 0, 1 and 6 hrs with 55mM extracellular KCl. To identify the gene programs regulated in these cells by the activity-induced early-response transcription factor Npas4, we repeated the same experiment in the MGE- and CTX-cultures lacking Npas4 (Npas4-KO).

Description
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
Normal erythropoiesis requires a critical balance between proapoptotic and antipaoptotic pathways. Bcl-xl, an antiapoptotic protein is induced at end-stages of differentiation of erythroid precursors in response to erythropoietin. The details of the proapoptotic pathway and the critical proapoptotic proteins inhibited by Bcl-xl in erythropoiesis are not well understood. We employed gene targeting to ablate Nix, a proapoptotic BH3-domain only Bcl2 family protein, which is known to be transcriptionally induced during erythropoiesis. Nix null mice exhibited reticulocytosis and thrombocytosis in the peripheral blood; and profound splenomegaly with erythroblastosis in the spleen and bone marrow despite normal erythropoietin levels and blood oxygen tension. In vivo apoptosis was diminished in erythroblast precursors from Nix null spleens. To define the molecular consequences of Nix ablation on apoptosis and erythropoiesis, we conducted a detailed comparative analysis of gene expression in spleens from 8 week old Nix null mice and wild type controls. Of 45,101 genes analyzed, 514 were significantly upregulated and 386 down-regulated in Nix-/- splenocytes. Functional cluster analysis delineated the ten most highly regulated gene sets, revealing increased levels of cell cycle and erythroid genes, with decreased levels of cell death and B-cell genes.

Description
Brown fat generates heat via the mitochondrial uncoupling protein UCP1, defending against hypothermia and obesity. Recent data suggest that there are two distinct types of brown fat: classical brown fat derived from a myf-5 cellular lineage and UCP1-positive cells that emerge in white fat from a non-myf-5 lineage. Here, we report the isolation of beige cells from murine white fat depots.

Description
An alternative promoter of the PGC-1alpha gene gives rise to three new PGC-1alpha isoforms refered to as PGC-1a2 (A2), PGC-1a3 (A3) and PGC-1a4 (A4). The proximal PGC-1 alpha promotor transcribes the canonical PGC-1 alpha which is refered to as PGC-1a1 (A1).G1/G2/G3 samples refer to the Green fluorescent protein (GFP) control samples used in this experiment. Forced expression of the PGC-1a4 isoform results in muslce hypertrophy associated with increased IGF-1 signaling and repression of myostatin signaling.

Description
Glucocorticoids (GC) are used as first line therapies for generalized suppression of inflammation (e.g. allergies or autoimmune diseases), but their long-term use is limited by severe side effects. Our previous work has revealed that GC induced a stable anti-inflammatory phenotype in monocytes, the glucocorticoid-stimulated monocytes (GCsM) that we now exploited for targeted GC-mediated therapeutic effects.
