Description
Much has been learned about transcriptional cascades and networks from large-scale systems analyses of high-throughput data sets. However, analysis methods that optimize statistical power through simultaneous evaluation of thousands of ChIP-seq peaks or differentially expressed genes possess substantial limitations in their ability to uncover mechanistic principles of transcriptional control. By examining nascent transcript RNA-seq, ChIP-seq, and binding motif data sets from lipid A-stimulated macrophages with increased attention to the quantitative distribution of signals, we identified unexpected relationships between the in vivo binding properties of inducible transcription factors, motif strength, and transcription. Furthermore, rather than emphasizing common features of large clusters of co-regulated genes, our results highlight the extent to which unique mechanisms regulate individual genes with key biological functions. Our findings demonstrate the mechanistic value of stringent interrogation of well- defined sets of genes as a complement to broader systems analyses of transcriptional cascades and networks. Overall design: Bone marrow-derived macrophages derived from C57Bl/6, Myd88-/-, Trif-/-, Irf3-/-, Ifnar-/-, and RelA-/- mice were stimulated with lipid A; C57Bl/6 macrophages were stimulated with lipid A in the presence of MAPK inhibitors or cycloheximide, or stimulated with PAM3CSK4 for 0, 15, 30, 60, and 120 minutes, or stimulated with lipid A for 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, and 60 minutes. Two biological replicates were generated for each time point for each treatment type.

Description
In adipocyte-specific knockout mice (Bcl6AKO), we found that Bcl6 deletion results in strikingly increased inguinal but not perigonadal adipocyte size and tissue mass in addition to marked insulin sensitivity. Genome-wide DNA binding and RNA expression analyses revealed that BCL6 controls gene networks involved in cell growth and fatty acid biosynthesis. Thus, our studies identify BCL6 as a negative regulator of subcutaneous adipose tissue expansion and metabolic health. Overall design: Identification of adipocyte BCL6-regulated genes

Description
Neurons utilize glucose to generate adenosine triphosphate (ATP) essential for their survival, excitability and synaptic signaling, as well as initiating changes in neuronal structure and function. Defects in oxidative metabolism and mitochondria functions are also associated with aging and diverse human neurological diseases1-4. While neurons are known to adapt their metabolism to meet the increased energy demands of complex behaviors such as learning and memory, the molecular underpinnings regulating this process remain poorly understood4-6. Here we show that the orphan nuclear receptor estrogen related receptor gamma (ERR) becomes highly expressed during retinoic-acid induced neurogenesis and is widely expressed in neuronal nuclei throughout the brain. Mechanistically, we show that ERR directly orchestrates the expression of networks of genes involved in mitochondrial oxidative phosphorylation and energy generation in neurons. The importance of this regulation is evidenced by decreased adaptive metabolic capacity in cultured neurons lacking ERR, and reduced long-term potentiation (LTP) in ERR-/- hippocampal slices. Notably, the defect in LTP was rescued by the metabolic intermediate pyruvate, functionally linking the ERR knockout metabolic phenotype and memory formation. Consistent with this notion, mice lacking neuronal ERR exhibit defects in spatial learning and memory. These findings implicate ERR in the metabolic adaptations required for long-term memory formation.

Description
SMRT (silencing mediator of retinoid and thyroid hormone receptors) is recruited by numerous transcription factors to mediate lineage and signal dependent transcriptional repression. We generated a knock-in mutation in the receptor interaction domain (RID) of SMRT (SMRTmRID) that solely disrupts its interaction with nuclear hormone receptors. SMRTmRID-derived 3T3-MEFs display a dramatically increased adipogenic capacity and accelerated differentiation rate. We measured global gene expression in wild-type versus SMRTmRID-derived 3T3-MEFs in the undifferentiated state to examine which pathways were altered. Our results demonstrate that SMRT-RID dependent repression is a key determinant of the adipogenic set point.
