A single-cell RNA-seq survey of the action profile of general anaesthetics on the human prefrontal cortex cells

Project description:The cellular and molecular actions of general anaesthetics to induce anaesthesia state and also cellular signalling changes for subsequent potential “long term” effects remain largely elusive although great efforts have been made to study these in vitro, ex vivo and in vivo settings. General anaesthetics were reported to act on voltage-gated ion channels and ligand-gated ion channels. Here we used single-cell RNA-sequencing complemented with whole-cell patch clamp and calcium transient techniques to examine the gene transcriptome and ion channels profiling of sevoflurane and propofol, both commonly used clinically, on human embryonic primary prefrontal cortex (PFC) mixed cell cultures. Both propofol and sevoflurane at clinically relevant dose/concentration promoted “microgliosis” but only sevoflurane changed microglia cell similarity. Propofol and sevoflurane each extensively but transiently altered transcriptome profiling 2 hours after anaesthetics exposure across microglia, excitatory neurons, interneurons, astrocytes and oligodendrocyte progenitor cells. Within the excitatory neurons and microglia, exemplary ion-gated and ligand-gated ion channels related genes response to either anaesthetic included SCN1A, CACNAB2, KCNA1, GABRR2 and GRINA1 amongst many others. Utilising scRNA-seq as a robust and high-throughput tool, our work may provide a comprehensive blueprint for future mechanistic studies of general anaesthetics in clinically relevant settings.

Rat prefrontal cortex LC-MS/MS

Project description:The prefrontal cortex is greatly associated with a wide range of mental health illnesses including schizophrenia, depression, bipolar disorder, anxiety and autism spectrum disorders. It richly expresses neuroreceptors which are the target for typical and atypical antipsychotics. However as the precise mechanism of action of antipsychotic medications are not known, proteomic studies of the effects of antipsychotic drugs on the brain are warranted. In the current study we aimed to characterise protein expression in the adult rodent prefrontal cortex (n=5 per group) following low dose treatment with the atypical antipsychotic Risperidone or saline (control) in adolescence (postnatal days 34-47). The prefrontal cortex was examined by triplicate one hour runs of label-free LC-MS/MS. The raw mass spectral data were analyzed with the MaxQuantTM software. Statistical analysis was carried out using SAS Version 9.1. Functional and pathway analysis was performed with DAVID.nih and Ingenuity Pathway Analysis respectively and the top five most implicated pathways were found to be clathrin mediated endocytosis, the tri cyclic acid cycle, remodelling of epithelial junctions, rho family GTPase signalling and mitochondrial dysfunction.This brief report summarises the proteomic data obtained from the study described, adds to the current repertoire of data available concerning the effects of atypical antipsychotic drugs on the brain and sheds light on their biological mechanisms.

Impact of clozapine and risperidone on the proteome of the rat prefrontal cortex (PFC) and remaining cortex (CX)

Project description:This study investigates the molecular mechanisms of action of clozapine and risperidone in the rat brain, specifically targeting the prefrontal cortex (PFC) and the remaining cortical regions (CX). A multi-platform proteomic approach was employed to capture comprehensive changes in protein expression induced by chronic (21 days) antipsychotic drug treatment.

Whole transcriptome RNA-seq of undiseased human prefrontal cortex

Project description:We report the application of high-throughput RNA sequencing to the human prefrontal cortex. The brain dataset was obtained by sequencing total RNAs extracted from the dorsolateral prefrontal cortex of five deceased human patients with no apparent pathology, followed by depletion of ribosomal RNA to obtain all non-rRNA coding and non-coding RNAs in the human brain transcriptome. Five samples were sequenced, four coming from frozen brain tissue (frontal cortex) of deceased female human patients with no remarkable pathology, and one from a male patient with no remarkable pathology.

Developmental Regulation and Individual Differences of Neuronal Epigenomes in the Prefrontal Cortex

Project description:We report global distribution of trimethylated Histone H3 Lysine 4 (H3K4me3) in human prefrontal cortex neurons at different ages Neuronal nuclei from human prefrontal cortex were isolated by FACS. Regions marked by H3K4me3 were identified by chromatin immunoprecipiation followed by deep sequencing.

Transcription profiling of human prefrontal cortex during postnatal development

Project description:Fresh frozen post mortem prefrontal cortex tissue (Brodman area 46) was obtained from 44 individuals varying in age from 0 to 49 years. RNA was extracted from these samples and hybridized to HG133plus2.0 GeneChips. The data was used to examine patterns of gene expression over the course of human postnatal developmental and ageing. PMI - postmortem interval, DLPFC - dorsolateral prefrontal cortex Experiment Overall Design: The dataset consists of 44 individuals varying in age from 0 to 49 years
