Transcriptional profiling of microdissected ventromedial hypothalamus in Nkx2-1 f/f vs. Nkx2-1 f/f; Sf1Cre female mice
Ontology highlight
ABSTRACT: Microdissected ventromedial hypothalamus (VMH) was profiled to identify transcriptional changes after Nkx2-1 ablation in female mice. Total RNA was extracted from conditional mutants (Nkx2-1 f/f; Sf1Cre) and floxed controls (Nkx2-1 f/f) at postnatal day 10 (P10) and profiled using Mouse ref8 v2.0 Illumina chips and reagents (n=4/group). The tissue profiled is microdissected ventromedial hypothalamus from P10 female mice. Controls and mutants are analyzed in quadruplicate.

Project description:We aimed to identify genes enriched in Nkx2-1-positive neurons in the dorsomedial hypothalamus (DMH). Using Nkx2-1-CreERT2 mice crossed with Rosa-ZsGreen mice after tamoxifen induction, we collected ZsGreen-marked Nkx2-1-positive neurons from the DMH, ventromedial hypothalamic nucleus (VMH), and arcuate nucleus (Arc) by laser microdissection and compared their gene expression profiles.
Project description:To uncover the cellular architecture of the mouse ventromedial hypothalamus (VMH), we used single nucleus RNA-seq (snRNA-seq) from wild-type mice.

Project description:Mice carrying a mutation which deletes Bmal1 in Gfap-expressing astrocytes, and control animals were fed either a standard diet or a high fat diet for 16 weeks. Conditional deletion of Bmal1 in Gfap cells decreased weight gain and increased energy expenditure under high fat diet, hence the transcriptome of Brown Adipose Tissue (BAT) and Ventromedial Hypothalamus (VMH) were obtained.
Project description:Analysis of gene expression regulated by FoxO1 in the ventromedial hypothalamus (VMH) of wildtype and knockout mice. Results provide important information of gene expression in the VMH. The transcription factor FoxO1 contributes to leptin and insulin action, including cells in the brain. However, the neurons mediating these effects and the identity of the molecular targets through which FoxO1 exerts metabolic actions remains to be defined.
Project description:The ventrolateral subdivision of the ventromedial hypothalamus (VMHvl) is essential for innate social behaviors including aggression and mating in female mice at different reproductive states. However, the female VMHvl transcriptomes in different reproducive states and their relationship behavioral functions are unknown. We performed single-cell RNA 10x sequencing and investigated correspondence between transcriptomic identity in different reproductive states and behavioral activation. Immediate early gene analysis from our Act-seq dataset identified that distinct T-types function in female aggression and mating behaviors.
Project description:The ventromedial nucleus of the hypothalamus (VMH) is thought to a satiety center and a potential target for anti-obesity therapy. Electroconvulsive seizure (ECS) therapy is highly effective in psychiatric diseases including depression, but also implicated beneficial effects on other neurological diseases. Although it has been reported that the neurons in the VMH are strongly activated by ECS stimulation, the effect of ECS in this hypothalamic subnucleus remains unknown. To address this issue, we investigated molecular changes in the VMH in response to ECS by utilizing a method of laser-capture microdissection coupled with microarray analysis, and examined behavioral effects of ECS via VMH activation. ECS significantly induced gene expression not only immediate-early genes such as Fos, Fosb and Jun, but also Bdnf, Adcyap1, and Hrh1 in the VMH after a single or repeated stimulus. Mice received one or 7 times shock of ECS and their brains were collected at 2 h (VMH_1stECS2h, VMH_7thECS2h) or 6 h after shock (VMH_1stECS6h, VMH_7thECS6h). The brains of sham-treated animals were collected at 2 h after treatment(VMH_sham). The VMH was microdissected from dehydrated brain sections, and its total RNA was extracted. RNA samples from two or three animals were pooled to minimize the impact of biological variance. After nucleotide amplification by the ovation amplification, the gene expression profiles were obtained by the Affymetrix microarray analysis. The microarray analysis was performed twice using different sets of animals.
