MetabolomicsRole of breast milk lipid composition in postnatal brain development.

Lipids in the brain play a crucial role as structural and signaling molecules, accounting for approximately 60% of the brain’s dry weight. Several lipid classes exhibit concentration profile differences between humans and other species, including closely related primates, with the most pronounced...

MetabolomicsTargeted metabolomics of pancancer brain metastasis

The molecular heterogeneity of brain metastases hampers therapeutic development for cures. To address this unmet and urgent need, we constructed a comprehensive multi-omic, single cell, and spatially resolved atlas of 1,032 pan-cancer brain metastases, identifying four robust molecular subtypes ...

MetabolomicsMass spectrometry imaging as an emerging tool for studying metabolism in human brain organoids

Human brain organoids are emerging models to study human brain development and pathology as they recapitulate the development and characteristics of major neural cell types, and enable manipulation through an in vitro system. Over the past decade, with the advent of spatial technologies,...

TranscriptomicsPurification of neuronal precursors from the adult mouse brain: a comprehensive gene expression analysis
The progeny of neural stem cells in the subventricular zone (SVZ) of the adult mammalian brain consists in polysialylated NCAM-expressing immature neurons (PSA(+) cells), which migrate to the olfactory bulb (OB) to differentiate into GABAergic interneurons. We purified murine PSA(+) cells directly f...

TranscriptomicsRNA-seq of brain mural cells and microvascular fragments
Purpose: Pericytes, the mural cells of blood microvessels, have come into focus as regulators of microvascular development and function, but due to paucity of defining markers, the identification and functional characterization of PC remain problematic, and reported data are often controversial. Her...

GenomicsPromoter Decommissioning by the NuRD Chromatin Remodeling Complex Triggers Synaptic Connectivity in the Mammalian Brain
Precise control of gene expression plays fundamental roles in brain development, but the roles of chromatin regulators in neuronal connectivity have remained poorly understood. Here, we find that depletion of the nucleosome remodeling and deacetylation (NuRD) complex in the cerebellar cortex by in v...

TranscriptomicsDeep sequencing analysis of the developing mouse brain reveals a novel microRNA
MicroRNAs (miRNAs) are small non-coding RNAs that can exert multilevel inhibition/repression at a post-transcriptional or protein synthesis level during disease or development. Characterisation of miRNAs in adult mammalian brains by deep sequencing has been reported previously. However, to date, no ...

TranscriptomicsGene expression profile of the neonatal female mouse brain after administration of testosterone propionate.
The aim of this study is to investigate the gene expression profiles during masculinization of neonatal female mice brain by exogenous androgen treatment. The results of our expression analysis will shed light on the identification of the key molecules of sexual differentiation of mammalian brain. E...

MetabolomicsSMN deficiency perturbs monoamine neurotransmitter metabolism in spinal muscular atrophy

Beyond motor neuron degeneration, homozygous mutations in the survival motor neuron 1 (SMN1) gene cause multiorgan and metabolic defects in patients with spinal muscular atrophy (SMA). However, the precise biochemical features of these alterations and the age of onset in the brain and peripheral ...
