ERRγ links adaptive neuronal metabolism to spatial learning and memory [ChIP-Seq]

ABSTRACT: 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 (ERRγ) becomes highly expressed during retinoic-acid induced neurogenesis and is widely expressed in neuronal nuclei throughout the brain. Mechanistically, we show that ERRγ 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 ERRγ, and reduced long-term potentiation (LTP) in ERRγ-/- hippocampal slices. Notably, the defect in LTP was rescued by the metabolic intermediate pyruvate, functionally linking the ERRγ knockout metabolic phenotype and memory formation. Consistent with this notion, mice lacking neuronal ERRγ exhibit defects in spatial learning and memory. These findings implicate ERRγ in the metabolic adaptations required for long-term memory formation.

ERRγ links adaptive neuronal metabolism to spatial learning and memory [Array data]

We used microarray analysis to compare the genome-wide gene expression changes between wild type (WT) and ERRγ-/- P0 cerebral cortex as it contains mainly neuronal lineage at this stage compared to adult cortex.

ERRγ coordinates a transcriptional program of mitochondrial and renal reabsorptive functions implicated in kidney disease [RNA-seq]

Project description:Here we show that estrogen-related receptor γ (ERRγ) is an essential transcriptional coordinator of both renal mitochondrial and reabsorptive functions. ERRγ is highly and specifically expressed in the RECs, and its expression correlates with kidney function in humans. We generated REC-ERRγ KO mice which developed severe renal mitochondrial and reabsorptive dysfunction and fluid-filled cysts. Transcriptome and cistrome analysis revealed that ERRγ directly regulates mitochondrial metabolism and renal reabsorption. ChIP-reChIP-Seq studies further suggest that ERRγ employs a distinct mechanism to regulate renal reabsorption genes through functional cooperation with hepatic nuclear factor 1 beta (HNF1β), mutations of which cause strikingly similar renal dysfunction and cysts in humans and animals. Together these findings reveal a novel role for ERRγ in simultaneously coordinating a transcriptional program for renal energy production via mitochondria and energy consumption to perform reabsorptive functions required for normal kidney function

Genome-wide chromatin binding of ERRα and ERRγ in SH-SY5Y cells

Project description:The SH-SY5Y Human neuroblastoma cell line was subcloned from the SK-N-SH cell line, which has been isolated from a bone marrow biopsy of a 4 year-old female patient. To examine the transcriptional regulation by ERRα and ERRγ in human neuronal cells, we investigated chromatin binding regions of ERRαlpha and ERRγ genome-wide in the SH-SY5Y cells. We detected thier target genes, which were largely overlap.

Mapping Gene Expression in Excitatory Neurons During Hippocampal Late-Phase Long-term Potentiation

Project description:The long-lasting changes in synaptic connectivity that underlie long-term memory require new RNA and protein synthesis for their persistence. To elucidate the temporal pattern of gene expression that gives rise to long-lasting, learning-related neuronal plasticity, we profiled RNAs in mouse hippocampal CA3-CA1 slices following induction of late phase long-term potentiation (LTP), analyzing differential expression (DE) specifically within pyramidal excitatory neurons by Translating Ribosome Affinity Purification RNA sequencing (TRAP-seq). We detected time-dependent changes in up- and down-regulated ribosome-associated mRNAs over the two hours following LTP induction, with minimal overlap of DE transcripts between time points. TRAP-seq revealed greater numbers and amplitudes of LTP-induced changes than RNA-seq of all cell types in the hippocampus. Transcripts that were DE by TRAP-seq but not RNA-seq were enriched in mRNAs encoding cytoskeletal and cell adhesion proteins, while RNA-seq identified DE in many non-neuronal mRNAs. Together our results highlight the importance of considering both the time course and the cell-type specificity of activity-dependent gene expression during memory formation.

Genome-wide maps of chromatin changes uppon contextual fear conditioning in mice (RNA-seq)

Project description:The ability to form memories is a prerequisite for an organismâs behavioural adaptation to environmental changes. At the molecular level, the acquisition and maintenance of memory requires changes in chromatin modifications. In an effort to unravel the epigenetic network underlying both short- and long-term memory, we examined chromatin modification changes in two distinct mouse brain regions, two cell-types, and three time-points before and after contextual learning. Here we show that histone modifications predominantly change during memory acquisition and correlate surprisingly little with changes in gene expression. While long-lasting changes are almost exclusive to neurons, learning-related histone modification and DNA methylation changes occur also in non-neuronal cell types, suggesting a functional role for non-neuronal cells in epigenetic learning. Finally, our data provides evidence for a molecular framework of memory acquisition and maintenance, wherein DNA methylation could alter the expression and splicing of genes involved in functional plasticity and synaptic wiring. We examined chromatin modification changes in two distinct mouse brain regions (CA1 and ACC), two cell-types (neurons, non-neurons), and three time-points before and after contextual learning (naive, 1h, 4w).
