Zinc Uptake and Storage During the Formation of the Cerebral Cortex in Mice

ABSTRACT: The aim of this work was to analyse the transcriptome of the mice cerebral cortex (or neocortex) during embryogenesis and at post-natal age. This complete transcriptomic analysis was dedicated to the analysis of the genes participating in the homeostasis of Zinc during brain development and formation. Our study represents a detailed analysis of transcriptomes during formation and dvelopment of the brain cortex, with biologic triplicates, generated by RNA-seq technology. This will provide a framework for comparative investigations of expression profiles. Our work offers an accurate quantitative and qualitative evaluation of mRNA content during mice embryogenesis.

Early remodeling of the neocortex upon episodic memory encoding

Project description:Understanding the mechanisms by which long-term memories are formed and stored in the brain represents a central aim of neuroscience. Prevailing theory suggests that long-term memory encoding involves early plasticity within hippocampal circuits, while reorganization of the neocortex is thought to occur weeks to months later to subserve remote memory storage. Here we report that long-term memory encoding can elicit early transcriptional, structural and functional remodeling of the neocortex. Parallel studies using genome-wide RNA-sequencing, ultrastructural imaging, and whole-cell recording in wild-type mice suggest that contextual fear conditioning initiates a transcriptional program in the medial prefrontal cortex (mPFC) that is accompanied by rapid expansion of the synaptic active zone and postsynaptic density, enhanced dendritic spine plasticity, and increased synaptic efficacy. To address the real-time contribution of the mPFC to long-term memory encoding, we performed temporally precise optogenetic inhibition of excitatory mPFC neurons during contextual fear conditioning. Using this approach, we found that real-time inhibition of the mPFC inhibited activation of the entorhinal-hippocampal circuit and impaired the formation of long-term associative memory. These findings suggest that encoding of long-term episodic memory is associated with early remodeling of neocortical circuits, identify the prefrontal cortex as a critical regulator of encoding-induced hippocampal activation and long-term memory formation, and have important implications for understanding memory processing in healthy and diseased brain states. 4 biological replicates per group were analyzed. The material analyzed was medial prefrontal cortex (mPFC; anterior cingulate cortex subregion) from both brain hemispheres, from which total RNA was extracted.

Human brain Alzheimer's - Proteomic signatures of brain regions affected by tau pathology in early and late stages of Alzheimer's disease

Project description:Alzheimer’s disease (AD) is the most common neurodegenerative disorder being characterized by progressive impairment of memory and cognition, resulting in dementia. To investigate brain region vulnerability to AD and which pathways are altered in certain areas in AD, we performed proteomic profiling of human brain samples during AD progression in regions early (medial temporal lobe - MTL) and late affected (neocortex) by tau pathology. We employed a mass spectrometry-based approach to interrogate the human brain proteome during AD progression (B/B stages) in four distinct brain regions: entorhinal cortex (EC), parahippocampal cortex (PHC), temporal cortex (TC) and frontal cortex (FC). Importantly, we wanted to evaluate brain areas that are affected by tau pathology in different disease stages, in order to gain insights if there are common mechanisms or patterns shared between different brain regions during disease progression. A total of 103 samples were analyzed by nanoLC-MS/MS.

Effect of Juvenile Environmental Tobacco Smoke Exposure on the Rat Frontal Cortex Neuroproteome

Project description:Exposure to secondhand tobacco smoke during early childhood has been linked with an increased risk for behavioral disorders, yet little is known regarding how brain development is impacted. Using an environmental tobacco smoke (ETS) passive inhalation model, this study assesses the neurodevelopmental impact of juvenile exposure during a critical period of frontal cortex development, specifically that of the rat orbital neocortex between postnatal days 8 and 22. Agnostic shotgun proteomics was employed to discern the biomolecular shift within this rapidly developing brain region that is responsible for higher-order behavioral control. The orbital cortex neuroproteome was assessed between ETS-exposed and room-air control animals employing a label-free shotgun approach with data-independent acquisition. Following protein roll-up, a total of X protein were found statistically altered in quantity out of Y total proteins identified. These results implicate a prominent shift within metabolic processes and synaptic organization related to excitatory and inhibitory neurotransmission. Findings derived from this dataset may further our understanding of how secondhand smoke exposure can perturb the orbital frontal cortex and result in developmental behavioral disorders.

Transcription profiling of different regions of E16.5 mouse cerebral cortex to identify region- and layer-specific genes.

Project description:The mammalian neocortex develops layer organizations with regional differences represented by expression of multiple genes at embryonic stages. These genes could play important roles in the formation of areal cyto-architecture, yet, the number of genes identified so far is not sufficient to explain such intricate processes. Here we collected five regions; the medial, dorsal, lateral, rostral, and occipital, from the dissected E16.5 mouse cerebral cortex and performed extensive gene expression analysis using the Affymetrix U74Av2 array. Keywords = mouse Keywords = cortex Keywords = development Keywords = regional Keywords = gene expression Keywords = medial Keywords = dorsal Keywords = lateral Keywords = rostral Keywords = occipital

Expression data from E17.5 mouse brain regions

Project description:During brain development, layer 5 neurons distributed across most areas of the neocortex innervate the pontine nuclei (basilar pons) by the initiation and extension of collateral branches interstitially along their corticospinally extending axons. We used microarrays to compare gene expression profiles of brain areas that were projected (pontine nucleus, superior colliculus) and were not projected (cerebellum, olfactory bulb) by axon collaterals from the corticospinal tract in order to understand genetic programs that regulate axon collaterals formation.
