Project description:FOXG1 syndrome is a developmental encephalopathy with a high phenotypic variability, which results from FOXG1 mutations. However, the upstream transcriptional regulation of Foxg1 expression remains unclear. Here we report that both deficiency and overexpression of Men1 (protein: menin, a pathogenic gene of MEN1 syndrome) result in autism-like behaviors, including social defects, increased repetitive behaviors and cognition impairments. We employed multifaceted transcriptome analyses and found that Foxg1 signaling is mostly altered in Men1 deficiency mice, through its regulation over Alpha Thalassemia/Mental Retardation Syndrome X-Linked (Atrx) factor. Atrx recruits menin to bind to the transcriptional start region of Foxg1 and mediates the regulation of Foxg1 expression by H3K4me3 modification. Notably, the described changes in menin deficient mice were rescued by over-expression of Foxg1, leading to normalized spine growth and hippocampal synaptic plasticity. Collectively, these results indicate a putative role of menin in maintaining Foxg1 expression, and menin signaling may serve as Foxg1-related encephalopathy therapeutic targets.

Project description:Next-generation sequencing facilitates quantitative analysis of the transcriptomes of FOXG1 100% dosage GABA interneurons, FOXG1 60% dosage GABA interneurons, FOXG1 30% dosage GABA interneurons, and FOXG1 0% dosage GABA interneurons derived from human embryonic stem cells. We report a genetic manipulation system that enable precise dosage control of FOXG1 protein in human pluripotent stem cells (hPSCs). Using this system, we explored how the various reduced dosage affect human ventrol GABA interneuron development. We employed RNA seq on hPSC-derived GABA interneurons (day 60) to invest the expression pattern under different FOXG1 dosage conditions. RNA-Seq on GABA interneurons (Day 60) indicates that compared to the FOXG1 100% group, variable insufficiency of FOXG1 produces more than 1000 differently expressed genes (DEGs), and more DEGs in the group with less FOXG1 dosage. Heat map on Pearson Correlation indicates that groups with more discriminated FOXG1 exhibit much weaker correlation. Venn diagram reveals that each group has a set of distinct DEGs, suggesting that each FOXG1 protein dosage could results in different expression pattern during differentiation. The DEGs can be divided into two clusters, with one showing dosage-dependent regulation by FOXG1 and the other one typical binary. Key regulatory genes for GABA interneuron induction (NKX2-1, NKX6-2, GAD1, etc.) and for functional GABAergic-specific synapse formation (GABBR1, GABRA1, GABRB1, GABRG1, GABRQ, SHANK1, etc.) are down regulated along with reduction of FOXG1 protein.

Project description:Rett syndrome is a complex neurodevelopmental disorder that is mainly caused by mutations in MECP2. However, mutations in FOXG1 cause a less frequent non-congenital form called atypical Rett syndrome. FOXG1 is a key transcription factor implicated in forebrain development, where it maintains the balance between progenitor proliferation and neuronal differentiation. Using SILAC based quantitative proteomics and genome-wide small RNA sequencing, we identified that FOXG1 interacts with the ATP-dependent RNA helicase, DDX5/p68 and controls the biogenesis of miRNAs. Both, FOXG1 and DDX5 bind to the miR200b/a/429 primary transcript and associate with the microprocessor complex, whereby DDX5 recruits FOXG1 to DROSHA. In vivo and in vitro experiments show that both FOXG1 and DDX5 are necessary for effective maturation of miR200b/a/429. RNAseq analyses of Foxg1-heterozygote hippocampi and miR200b/a/429 overexpressing Neuro-2a cells revealed that the cAMP-dependent protein kinase type II-beta regulatory subunit (PRKAR2B) is a target of miR200 in neural cells. Since it is known that PRKAR2B inhibits postsynaptic functions by attenuating protein kinase A (PKA) activity, increased PRKAR2B levels may contribute to neuronal dysfunctions in FOXG1 Rett syndrome.

Project description:The forkhead box transcription factor FoxG1 is known to influence forebrain development by determining regional brain specification as well as by regulating expansion of neuronal progenitors and timing of their differentiation. In the adult brain, FoxG1 is expressed in cortex and hippocampus. In the latter it is involved in postnatal neurogenesis in the dentate gyrus by influencing maintenance of the progenitor pool as well as survival and maturation of postmitotic neurons. In humans, haploinsufficiency of FoxG1 causes the congenital version of the Rett syndrome, a progressive neurologic developmental disorder. We use FoxG1 mutant mice to screen for global changes in mRNA expression after partial loss of FoxG1 protein in hippocampi of six week-old mice. Data analysis points to a specific function for FoxG1 in adult hippocampus besides its known involvement in dentate gyrus neurogenesis. We analyse transcriptional changes in the different CA-fields and show that especially the CA-1 field is influenced by lack of FOXG1 protein. Furthermore, data analysis shows altered expression of genes that have also been implicated in the classical form of the Rett syndrome and other autism spectrum disorders.

Project description:The goal of the study was to identify the binding site of Foxg1 in wild-type cortex by performing ChIP-seq using a Foxg1 antibody. E14-15 cortical tissues were dissected, lysed and fixed. Chromatin was prepared by sonication. Sequences bound by Foxg1 protein was precipitated using a Foxg1 antibody. Sequencing was performed on Illumina Genome Analyzer II. Foxg1 binding peaks were called using MACS.

Project description:Multiple endocrine neoplasia type I (MEN1) is a familial cancer syndrome characterized primarily by tumors of multiple endocrine glands. The gene for MEN1 encodes a ubiquitously expressed tumor suppressor protein called menin. Menin was recently shown to interact with several components of a trithorax family histone methyltransferase complex including ASH2, Rbbp5, WDR5, and the leukemia proto-oncoprotein MLL. To elucidate menin's role as a tumor suppressor and gain insights into the endocrine-specific tumor phenotype in MEN1, we mapped the genomic binding sites of menin, MLL1, and Rbbp5, to approximately 20,000 promoters in HeLa S3, HepG2, and pancreatic islet cells using the strategy of chromatin-immunoprecipitation coupled with microarray analysis. We found that menin, MLL1, and Rbbp5 localize to the promoters of thousands of human genes but do not always bind together. These data suggest that menin functions as a general regulator of transcription. Keywords: ChIP/chip NHGRI Menin ChIP-Chip

Project description:Inactivating mutations in the MEN1 gene predisposing to the multiple endocrine neoplasia type 1 (MEN1) syndrome can also cause sporadic pancreatic endocrine tumors. MEN1 encodes menin, a subunit of MLL1/MLL2-containing histone methyltransferase complexes that trimethylate histone H3 at lysine 4 (H3K4me3). The importance of menin-dependent H3K4me3 in normal and transformed pancreatic endocrine cells is unclear. To study the role of menin-dependent H3K4me3, we performed in vitro differentiation of wild-type as well as menin-null mouse embryonic stem cells (mESCs) into pancreatic islet-like endocrine cells (PILECs). Gene expression analysis and genome-wide H3K4me3 ChIP-Seq profiling in wild-type and menin-null mESCs and PILECs revealed menin-dependent H3K4me3 at the imprinted Dlk1-Meg3 locus in mESCs, and all four Hox loci in differentiated PILECs. Specific and significant loss of H3K4me3 and gene expression was observed for genes within the imprinted Dlk1-Meg3 locus in menin-null mESCs and the Hox loci in menin-null PILECs. Given that the reduced expression of genes within the DLK1-MEG3 locus and the HOX loci is associated with MEN1-like sporadic tumors, our data suggests a possible role for menin-dependent H3K4me3 at these genes in the initiation and progression of sporadic pancreatic endocrine tumors. Furthermore, our investigation also demonstrates that menin-null mESCs can be differentiated in vitro into islet-like endocrine cells, underscoring the utility of menin-null mESC-derived specialized cell types for genome-wide high-throughput studies. Genome-wide mapping of H3K4me3 and microarray gene expression profiling in TC-1 wild-type (WT) mESCs, menin-null (Men1-ko) mESCs (3.2N), pancreatic islet-like endocrine cells (PILECs) derived from WT mESCs, and PILECs derived from Men1-ko mESCs.
