Project description:In the past few decades, the prevalence of overweight and obesity has sharply increased in children and adolescents. Childhood obesity life are associated with increased risk of cardiovascular disease (CVD), diabetes mellitus, metabolic syndrome, sleep disturbances and certain cancers in adulthood. Childhood obesity has become a serious global public health challenge. Long noncoding RNAs (lncRNAs) have an important role in adipose tissue function and energy metabolism homeostasis, and abnormalities may lead to obesity. We used microarrays to detail the differential expression profile of lncRNAs and mRNAs in obese children compared with non-obese children.

Project description:In order to understand heterogeneity of MCH neurons, by using MCH-Cre dependent ZsGreen (fl/fl) reporter mice, we isolated nuclear from 16 hypothalami of 16 mice at the age of 16-18weeks. Through flow cytometry, we were able to distinguish ZsGreen positive nuclei, and collected puried MCH nuclei in suspension. Those nuclei suspension were subjected to single cell sequence by 10x™ GemCode™ Technology for further single nuleus mRNA analysis and unravel subclusters of MCH neurons

Project description:We report phosphoRiboTrap experiments result which aim to explore the nature of the cell types in the Median Eminence (ME) regulated as a consequene of chemogenetic MCH neuron activation. Control and MCH-hM3Dq mice were 12 hrs-fasted and i.p. injected with CNO (3 mg/kg), Arcuate (ARC) and median eminence expat were extracted for preciptation of S6-marked ribosomes from both groups of mice. Extracted RNA from Immunoprecipitated ribosomes (IP) and total tissue (ARC+ME) from each mouse were subjected to deep mRNA sequencing. By analyzing the overlap of genes enriched in the IP/Input of MCH neuron activated mice with previously identified cell types using single cell mRNA sequencing of cells in the mediobasal hypothalamus (Campbell et al., 2017), we identified gene clusters which were activated upon MCH neuron activation.

Project description:The postnatal neurodevelopmental disorder Rett syndrome (RTT) is caused by mutations in the gene encoding Methyl-CpG-binding Protein 2 (MeCP2). Despite decades of research, it remains unclear how MeCP2 actually regulates transcription or why RTT features appear only 6-18 months after birth. We examined MeCP2 binding to methylated cytosine in the CH context (mCH, where H = A, C, or T) in the adult mouse brain and found that MeCP2 binds these mCH sites, influencing nucleosome positioning and transcription. Strikingly, this pattern is unique to the mature nervous system, as it requires the increase in mCH after birth to reveal differences in MeCP2 binding to mCG, mCH, and non-methylated DNA elements. This study provides insight into the molecular mechanism governing MeCP2 targeting and how this targeting might contribute to the delayed onset of RTT symptoms. MeCP2 ChIP-Seq were conducted from ~ 7-week-old hypothalamus tissues from Mecp2-/y; MECP2-EGFP mice.

Mnase-Seq were conducted from 7-week-old hypothalamus from MeCP2 knockout mice and their age and genetic background matched wild types control mice.

Project description:We sequenced total 12 samples: 3 samples at day 0 without Insulin induction, 3 samples at day 0 with MCH treatment, 3 samples at day 2 after insulin induction, 3 samples at day 2 after insulin inducation and MCH treatment.
