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

ABSTRACT: 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.

Expression data from glioblastoma surgical specimens

Project description:Surgical resection is the first choice of the standardized treatment scheme for glioblastoma and is performed under general anesthesia. Previous researches have shown that propofol and sevoflurane have different effects on the biological process of glioma cells from the molecular level. Some of them, for instance, control the glioma cell proliferation, invasion and migration In vitro or In vivo. We used mRNA microarray to discuss the effects of propofol and sevoflurane on gene expression in patients with glioblastoma. The correlation between DEGs and patients’ prognosis was further analyzed.

Gene expression of brain regions activated by sevoflurane and propofol

Project description:The basic mechanisms of action for general anesthesia are not fully understood. We thought differences in the neural activation sites of different types of anesthetics and differences in gene expression changes in those brain regions may lead to differences in the incidence of side effects. We performed gene expression analysis using microarrays in the identified regions that have been related to the mechanisms of anesthetic action and side effects. Gene expression changes in these brain regions were determined for sevoflurane and propofol to understand the mechanisms that cause differences among anesthetics.

Deep sequencing of somatosensory neurons reveals molecular determinants of intrinsic physiological properties

Project description:To explore the molecular basis of the distinct intrinsic membrane properties and other dstinguishing features of functionally defined DRG neuron subtypes, we bulk-sequenced RNA at high depth of genetically-labeled DRG neurons to generate transcriptome profiles of eight major DRG neuron subtypes. The trancriptome profiles revealed differentially expressed and functionally relevant genes, including voltage-gated ion channels. Guided by the transcriptome pofiles, electrophysiological analyses using pharmacological and genetic manipulations as well as computational modeling of DRG neuron subtypes were undertaken to assess the functions of select voltage-gated potassium channels (Kv1, Kv2, Kv3, and Kv4) in shaping action potential (AP) waveforms and firing patterns of the DRG neuron subtypes. Our findings show that the transcriptome profiles have predictive value for defining ion channel contributions to sensory neuron subtype-specific intrinsic physiological properties.

Transcription profiling of human atrial tissue from patients undergoing coronary artery bypass graft surgery to determine the effect of anesthesia on gene expression

Project description:Anesthetic gases elicit organ protection in patients undergoing coronary artery bypass graft (CABG) surgery. This study aimed at identifying myocardial transcriptional phenotypes and anesthetic-induced changes in gene expression to predict cardiovascular biomarkers and cardiac function after off-pump CABG. Experiment Overall Design: Patients scheduled for off-pump CABG were randomized into a group with the anesthetic gas sevoflurane (n=10) or the intravenous anesthetic propofol (n=10). Atrial samples were collected at the beginning and end of bypass surgery to determine gene expression profiles.

Rat Brain LC-MS/MS - Quantitative Proteomics Reveals Protein-Protein Interactions with Fibroblast Growth Factor12 as a Component of the Nav1

Project description:Voltage-gated sodium channels are responsible for the initiation and propagation of action potentials in excitable cells. While the channel is functional on its own, it is the transient and stable protein-protein interactions that modulate functional outcomes. AP-MS has been successfully applied to a number of ion channels. However to the best of our knowledge, no AP-MS study has been carried out on any member of the voltage-gated sodium channel family.

Disturbance of key cellular subproteomes upon propofol treatment is associated with increased permeability of the blood-brain barrier

Project description:Background: Propofol is a short-acting anesthetic, which is often used for induction and maintenance of general anesthesia, sedation for mechanically ventilated adults and procedural sedation. Several side effects of propofol are known and a substantial number of patients suffer from post-operative delirium after propofol application. In this study, we analyzed the effect of propofol on the function and protein expression profile on a proteome-wide scale. Methods: We cultured human brain microvascular endothelial cells in the absence and presence of propofol and analyzed the permeability of the blood-brain barrier (BBB) by fluorescein passage and protein expression on a proteome-wide scale by mass spectrometry. Results: Propofol interfered with the function of the blood-brain barrier. This was not due to de-creased adhesion of propofol-treated human brain microvascular endothelial cells. The proteomic analysis revealed that some key pathways in these cells were disturbed, such as oxygen metabolism, DNA damage recognition and response to stress. Conclusions: Propofol has strong effects on protein expression which could explain several side effects of propofol.

Developmental gene expression differences between neonatal and adult mouse atria and ventricles

Project description:We study the role of glycosylation in ion channel function. Specfically, we are focusing on how ion channel glycosylation modulates, controls, and impacts cardiac, skeletal muscle, and neuronal electrical activity. We wish to determine differences in gene expression through development and between the atria and ventricles of the mouse heart. Our data indicate differential sialylation directly affects voltage-gated sodium channel function through the developing heart in a chamber-specific manner. We wish to expand our findings to include other ion channels involved in the cardiac action potential, and to eventually create a map of the cardiac conduction system that details the role of differential glycosylation in cardiac excitability. Determining differential expression of the genes that regulate ion channel glycosylation is vital to these goals.

Transcriptomic profiling and electrophysiological analysis from microtransplanted synaptic membranes

Project description:Alterations of synaptic function in individuals with schizophrenia have been found in transcriptomics, proteomics, and genome wide association studies. Impaired synaptic glutamatergic (excitatory) and GABAergic (inhibitory) neurotransmission in affected brain regions (e.g. dorsolateral prefrontal cortex; DLPFC) is thought to be involved in the core symptoms of schizophrenia. However, there are no quantitative measurements of synaptic function in the human DLPFC, therefore concrete and specific functional alterations of voltage gated ion channels of glutamate and GABA receptors are lacking. We have begun to address this problem by directly measuring AMPA- and GABA receptor-mediated synaptic currents in postmortem brains from subjects with schizophrenia and contrasting to controls. We demonstrate in our preliminary work that the function of synaptic receptors is maintained in postmortem brains and is significantly decreased in schizophrenia compared to controls. Our overarching hypothesis is that reductions in both inhibitory and excitatory currents underlie synaptic deficits in schizophrenia. We will test rigor and reproducibility of this hypothesis in independent case-control cohorts. These deficits in synaptic currents can be statistically modeled with transcriptomic data which will be useful in downstream studies that pharmacologically challenge activation of these currents.
