Genome-wide analysis of gene expression in the paraventricular nucleus of Sim1-Cre specific DNMT3a deletion mice.

Project description:Analysis of gene expression in the paraventricular nucleus in the hypothalamus (PVH) of WT and Sim1-Cre specific DNMT3a deletion mice. Results provide important information about genes regulated by DNMT3a. For the gene expression profiling, total RNA was extracted from PVH of WT and Sim1-Cre specific DNMT3a deletion mice (C57BL6 background) at 6 weeks old using Qiagen RNeasy Lipid Tissue Mini Kit (Qiagen) and Phase Lock Gel (5 Prime Inc., Gaitherburg, MD). To make sure reproducibility and biological significance, triple hybridizations were performed for each genotype with the RNA from 3 indipendent PVH samples, each sample contains RNA from 5 animals. Genomics and Microarray Core Facility at UTSW (http://microarray.swmed.edu/) checked RNA quality with Bioanalyzer Chip and processed the samples for hybridization with Illumina Mouse-6 V2 BeadChip (Illumina Inc., San Diego, CA). We used GeneSpring GX (Agilent Technologies, Santa Clara, CA) for data analysis.

Changes in miRNA expression in offspring hypothalamus after exposure to maternal obesity

Project description:The purpose of this study was to identify miRNA that are differentially regulated in the arcuate nucleus of the hypothaamus (ARC) and paraventricular nucleus of the hypothalamus (PVH) after perinatal exposure to maternal obesity.

Transcription profiling of paraventricular hypothalamic nucleus (PVH) from mice stimulated by either LPS injection or restraint to understand the molecular mechanisms in the modulation of PVH responses to categorically distinct stressors.

Project description:The paraventricular hypothalamic nucleus (PVH) is a key site for integrating neuroendocrine, autonomic, and behavioral adjustments to diverse homeostatic challenges, including physiological (e.g., infection or hemorrhage) and emotional [e.g., restraint (RST) or footshock] stresses. Both types of challenges ultimately converge to activate common response systems represented in PVH, including the hypothalamo-pituitary-adrenal axis and the sympathoadrenal system. Oligonucleotide microarrays (U74A; Affymetrix, Santa Clara, CA) were used to compare and contrast gene expression profiles in the PVH elicited at 1 and 3 hr after acute exposure to representative physiological [intraperitoneal injection of 10 microg lipopolysaccharide (LPS)] and emotional (30 min RST) stressors. In general, the two challenges recruited relatively few genes in common, with the degree of overlap varying across functional classes of genes. The greatest degree of commonality was seen among signaling molecules and neuropeptides, whereas transcription factors upregulated by RST and LPS were largely distinct. Unexpectedly, RST induced a number of immune-related molecules, which were not regulated by LPS. Hybridization histochemical analyses localized a subset of responsive transcripts to the PVH and/or immediately adjoining regions. Immunerelated molecules in particular distributed broadly to vascular and other barrier-associated cell types. These global transcriptional profiles inform the search for early (transcription factors) and late (target genes) mechanisms in the modulation of PVH, and generalized CNS, responses to categorically distinct stressors.

A neural basis for melanocortin-4 receptor-regulated appetite.

Project description:Pro-opiomelanocortin (POMC)- and agouti-related peptide (AgRP)-expressing neurons of the arcuate nucleus of the hypothalamus (ARC) are oppositely regulated by caloric depletion and coordinately stimulate and inhibit homeostatic satiety, respectively. This bimodality is principally underscored by the antagonistic actions of these ligands at downstream melanocortin-4 receptors (MC4R) in the paraventricular nucleus of the hypothalamus (PVH). Although this population is critical to energy balance, the underlying neural circuitry remains unknown. Using mice expressing Cre recombinase in MC4R neurons, we demonstrate bidirectional control of feeding following real-time activation and inhibition of PVH(MC4R) neurons and further identify these cells as a functional exponent of ARC(AgRP) neuron-driven hunger. Moreover, we reveal this function to be mediated by a PVH(MC4R)→lateral parabrachial nucleus (LPBN) pathway. Activation of this circuit encodes positive valence, but only in calorically depleted mice. Thus, the satiating and appetitive nature of PVH(MC4R)→LPBN neurons supports the principles of drive reduction and highlights this circuit as a promising target for antiobesity drug development.

Grouped ensemble coding of behavioral states by combinations of molecularly defined cell types

Project description:We used a plate-based method (SMART-SCRB) to transcriptionally profile manually picked single neurons from the paraventricular nucleus of hypothalamus (PVH) from 10 male Agrp-IRES-Cre crossed with Ai9 reporter mice, all >7 weeks old. For each mouse, the PVH was dissected and cells expressing the tdTomato reporter were manually selected and placed into wells of a series of 96-well plates. We used a plate-based method with cell and transcript barcording and reverse transcription in each well, followed by pooling and amplification using a modified SMART-Seq technology that yields digital 3' end counts of transcripts.

Liver phosphoproteomics in response to AgRP activated neurons in the presence/absence of NPY

Project description:Autophagy represents a key regulator of aging and metabolism upon cell autonomous sensing of energy deprivation. We find that fasting in mice activates autophagy in liver paralleled by activation of hypothalamic AgRP neurons. Optogenetic and chemogenetic activation of AgRP neurons induces autophagy, alters phosphorylation of autophagy regulators and promotes ß-oxidation in the liver. AgRP neuron dependent induction of liver autophagy relies on NPY expression in these neurons. AgRP neuron projections in the paraventricular nucleus of the hypothalamus (PVH) and the lateral hypothalamus (LHA) mediate AgRP neuron-dependent control of liver autophagy. Conversely, inhibiting AgRP neurons during energy deprivation abrogates induction of hepatic autophagy and re-wiring of metabolism. Finally, AgRP neuron activation increases circulating corticosterone concentrations, and reduction of hepatic glucocorticoid receptor expression attenuates AgRP neuron-dependent activation of hepatic autophagy. Collectively, our study reveals a fundamental regulatory principle of non-cell autonomous control of liver autophagy in control of metabolic adaptation during nutrient deprivation.

Different DNA methylation between hypothalamus paraventricular (PVH) and ventromedial (VMH) nuclei

Project description:The goal is to compare the DNA methylation patterns between ARH and PVH to examine to what extent DNA methylation is region specific in genome scale. ARH and PVH were micro-dissected from mice brains. Each 7 pieces of ARH or PVH were pooled and used for DNA methylation comparison by methylation specific amplification microarray (MSAM). As a brief description of the MSAM: 500ng of genomic DNA was serially digested with SmaI and XmaI followed by an adaptor ligation and adaptor mediated PCR amplification and then cohybridization. Two-color cohybridizations were performed as paired comparison of PVH vs. ARH with two biological replicates including dye swap.
