Novel transcriptional networks regulated by CLOCK in human neurons

ABSTRACT: The molecular mechanisms underlying human brain evolution are not fully understood; however, previous work suggested that expression of the transcription factor CLOCK in the human cortex might be relevant to human cognition and disease. In this study, we investigated this novel transcriptional role for CLOCK in human neurons by performing chromatin-immunoprecipitation sequencing for endogenous CLOCK in adult neocortex and RNA-sequencing following CLOCK knockdown in differentiated human neurons in vitro. These data suggested that CLOCK regulates expression of genes involved in neuronal migration, and a functional assay showed that CLOCK knockdown increased neuronal migratory distance. Furthermore, dysregulation of CLOCK disrupts co-expressed networks of genes implicated in neuropsychiatric disorders, and the expression of these networks are driven by hub genes with human-specific patterns of expression. Thus, these data support a role for CLOCK-regulated transcriptional cascades involved in human brain evolution and function.

ELAVL2-regulated transcriptional networks in human neurons link atlernative splicing, autism and human neocortical evolution

Project description:The role of post-transcriptional gene regulation in human brain development and cognitive diseases remains mostly uncharacterized. ELAV-like RNA binding proteins are a family of proteins that regulate several aspects of neuronal function including neuronal excitability and synaptic transmission. Here, we identify the downstream transcriptional networks of ELAVL2, an RNA-binding protein with unknown function in the brain. We knockdown expression of ELAVL2 in human neurons and conduct RNA-sequencing, identifying networks of differentially expressed and alternatively spliced genes with altered ELAVL2. These networks contain autism-relevant genes as well as previously identified targets of other RNA binding proteins implicated in autism spectrum disorders such as RBFOX1 and FMRP. ELAVL2-regulated coexpression networks are also enriched for synaptic genes as well as genes with human-specific patterns of gene expression in the frontal pole. Together, these data suggest that ELAVL2 regulation of transcript expression is critical for neuronal functions at risk in autism spectrum disorders and such mechanisms of post-transcriptional gene regulation may have contributed to human brain evolution.

Transcriptional networks identify synaptotagmin-like 3 as a regulator of cortical neuronal migration during early neurodevelopment

Project description:Human brain development is a complex process involving neural proliferation, differentiation, and migration which are directed by many essential cellular factors and drivers. Here, using the NetBID2 algorithm and developing human brain RNA sequencing(RNA-Seq) dataset, we identified synaptotagmin-like 3(SYTL3) as one of the top drivers of early human brain development. Interestingly, SYTL3 exhibited high activity but low expression in both early developmental human cortex and human embryonic stem cell(hESC)-derived neurons. Knockout of SYTL3(SYTL3 -KO) in human neurons or knockdown of Sytl3 in embryonic mouse cortex markedly promoted neuronal migration. Besides, SYTL3-KO caused an abnormal distribution of deep-layer neurons in brain organoids and reduced presynaptic neurotransmitter release in hESC-derived neurons. We further demonstrated that SYTL3-KO- accelerated neuronal migration was modulated by high expression of matrix metalloproteinases. Together, based on bioinformatics and biological experiments, we identified SYTL3 as a novel regulator of cortical neuronal migration in human and mouse developing brains.

Networks of cultured iPSC-derived neurons reveal the human synaptic activity-regulated adaptive gene program

Project description:We studied the synaptic activity-regulated gene expression response in the human genetic background using cultured human iPSC-derived (hiPSCd) neuronal networks and networks of hiPSCd neurons mixed with mouse primary neurons. Our results confirm that genetic changes affect the synaptic activity-regulated gene program, proposing a functional mechanism how they have driven evolution of human cognitive abilities.

Transcription profiling of Drososphila circadian neuronal circuit identifies novel circadian genes

Project description:Gene expression profiling of distinct members of a neuronal circuit has the potential to identify candidate molecules and mechanisms that underlie the formation, organization and function of the circuit. To this end, we report here the application of a novel method to characterize RNAs from small numbers of specific Drosophila brain neurons, which belong to the circadian circuit. We identified three different sets of mRNAs enriched in different subclasses of clock neurons: one is enriched in all clock neurons, a second is enriched in PDF-positive clock neurons and a third is enriched in PDF-negative clock neurons. Moreover, we characterized 2 novel genes, Fer2 and dnocturnin, one from each subgroup, which highlight subgroup-specific features and play important roles in circadian rhythms. The methodology is a powerful tool not only to dissect the cellular and molecular basis of circadian rhythms but also to molecularly characterize other Drosophila neuronal circuits. Experiment Overall Design: Circadican related neuronal celltypes (Tim, Pdf) or general neurons (Elav) were labeled by GFP or YFP using specific Gal4 drivers. Expression of those celltypes were profiled after manual sorting of those GFP or YFP positive cells. 3 biological replicates were collected (except adult small pdf cells).

Critical role of histone turnover in neuronal transcription and plasticity [ChIP-seq]

Project description:Turnover and exchange of nucleosomal histones and their variants, a process long believed to be static in post-replicative cells, remains largely unexplored in brain. Here, we describe a novel mechanistic role for HIRA (histone cell cycle regulator) and proteasomal degradation associated histone dynamics in the regulation of activity-dependent transcription, synaptic connectivity and behavior. We uncover a dramatic developmental profile of nucleosome occupancy across the lifespan of both rodents and humans, with the histone variant H3.3 accumulating to near saturating levels throughout the neuronal genome by mid-adolescence. Despite such accumulation, H3.3 containing nucleosomes remain highly dynamic–in a modification independent manner–to control neuronal- and glial- specific gene expression patterns throughout life. Manipulating H3.3 dynamics in both embryonic and adult neurons confirmed its essential role in neuronal plasticity and cognition. Our findings establish histone turnover as a critical, and previously undocumented, regulator of cell-type specific transcription and plasticity in mammalian brain. All ChIP-seq samples were generated to test the impact of neuronal activity/adult physiological plasticity on histone turnover in the central nervous system. This was tested in cultured neurons and astrocytes, FACS purified neurons or FACS purified Glia.

Erythropoietin re-wires cognition-associated transcriptional networks

Project description:Recombinant human erythropoietin (rhEPO) has potent procognitive effects, likely hematopoiesis-independent, but underlying mechanisms and physiological role of brain-expressed EPO remained obscure. Here, we provide transcriptional hippocampal profiling of male mice treated with rhEPO. Based on ~108,000 single nuclei, we unmask multiple pyramidal lineages with their comprehensive molecular signatures. By temporal profiling and gene regulatory analysis, we build developmental trajectory of CA1 pyramidal neurons derived from multiple predecessor lineages and elucidate gene regulatory networks underlying their fate determination. With EPO as ꞌtoolꞌ, we discover populations of newly differentiating pyramidal neurons, overpopulating to ~200% upon rhEPO with upregulation of genes crucial for neurodifferentiation, dendrite growth, synaptogenesis, memory formation, and cognition. Using a Cre-based approach to visually distinguish pre-existing from newly formed pyramidal neurons for patch-clamp recordings, we learn that rhEPO treatment differentially affects excitatory and inhibitory inputs. Our findings provide mechanistic insight into how EPO modulates neuronal functions and networks.

miR-124 coordinates metabolic regulators acting at early stages of human neurogenesis

Project description:Metabolic dysregulation of neurons is associated with diverse human brain disorders. Metabolic reprogramming occurs during neuronal differentiation, but it is not fully understood which molecules regulate metabolic changes at the early stages of neurogenesis. In this study, we report that miR-124 is a driver of metabolic change at the initiating stage of human neurogenesis. Proteome analysis has shown the oxidative phosphorylation pathway to be the most significantly altered among the differentially expressed proteins (DEPs) in the immature neurons after the knockdown of miR-124. In agreement with these proteomics results, miR-124-depleted neurons display mitochondrial dysfunctions, such as decreased mitochondrial membrane potential and cellular respiration. Moreover, morphological analyses of mitochondria in early differentiated neurons after miR-124 knockdown result in smaller and less mature shapes. Lastly, we show the potential of identified DEPs as novel metabolic regulators in early neuronal development by validating the effects of GSTK1 on cellular respiration. GSTK1, which is upregulated most significantly in miR-124 knockdown neurons, reduces the oxygen consumption rate of neural cells. Collectively, our data highlight the roles of miR-124 in coordinating metabolic maturation at the early stages of neurogenesis and provide insights into potential metabolic regulators associated with human brain disorders characterised by metabolic dysfunctions.

Circular RNAs in the mammalian brain are highly abundant, conserved, and dynamically expressed

Project description:Circular RNAs (circRNAs) are an endogenous class of animal RNAs. Despite their abundance, their function and expression in the nervous system are unknown. Therefore, we sequenced RNA from different brain regions, primary neurons, isolated synapses, as well as during neuronal differentiation. Using these and other available data, we discovered and analyzed thousands of neuronal human and mouse circRNAs. circRNAs were extraordinarily enriched in the mammalian brain, well conserved in sequence, often expressed as circRNAs in both human and mouse, and sometimes even detected in Drosophila brains. circRNAs were overall upregulated during neuronal differentiation, highly enriched in synapses, and often differentially expressed compared to their mRNA isoforms. circRNA expression correlated negatively with expression of the RNA-editing enzyme ADAR1. Knockdown of ADAR1 induced elevated circRNA expression. Together, we provide a circRNA brain expression atlas and evidence for important circRNA functions and values as biomarkers. To assess circRNA expression in mammalian brain, we sequenced and analyzed mouse brain regions (hippocampus, cerebellum, prefrontal cortex and olfactory bulb), various neuronal differentiation (mouse P19 and human SH-SY5Y cells) and maturation (mouse cortical neurons) stages, and subcellular compartments in mouse (synaptoneurosomal fraction, cytoplasmic fraction, whole brain lysate).
