Gene expression of brain regions activated by sevoflurane and propofol

ABSTRACT: 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.

Effects of Propofol Treatment in Neural Progenitors Derived from Human Induced Pluripotent Stem Cells

Project description:Propofol is an intravenous anesthetic that has been widely used in the clinical setting. Besides its anesthetic effects, propofol has been reported to influence the regulation of autonomic system. Controversies exist with regards to whether propofol exposure is safe for pregnant women and young children. The recent emergence of human induced pluripotent stem cells (hiPSCs) has provided a promising and theoretically inexhaustible source of neural progenitor cells (NPCs) for drug testing, which could be extended to in vitro experiments for anesthetics such as propofol. NPCs derived from three hiPSC lines, NES-GFP (a NESTIN-GFP reporter), USCK7 (iPSCs derived from urine derived cells), and ND2-0 (NIH), were treated with propofol at different concentrations (20, 50, 100 and 300 µM) for 6 h or 24 h. Early and late cell injury, cell proliferation and apoptosis were evaluated. Comparison of genome-wide gene expression profiles was performed for propofol-treated and untreated control iPSC-NPCs. Propofol treatment of NPCs for 6 h at the clinically relevant concentration (20 or 50 µM) did not affect cell viability, apoptosis, or proliferation, while propofol at higher concentration (100 or 300 µM) decreased NPC viability and induced apoptosis. Prolonged treatment of propofol for 24 h significantly decreased cell viability. In addition, 20 µM propofol treatment for 6 h did not alter global gene expression. Higher concentration of propofol exerted potential cytotoxicity via multiple cellular mechanisms. In summary, propofol treatment at commonly practiced clinical doses for 6 h did not have adverse effects on hiPSC-derived NPCs. In contrast, longer exposure and/or higher concentration of propofol treatment could decrease NPC viability and induce apoptosis.

Propofol and Sevoflurane Anesthesia in Colorectal Cancer Surgery: Incidence of Acute Kidney Injury

Project description:The goal of this observational study is to compare anesthetic modalities (intravenous propofol anesthesia with sevoflurane gas anesthesia) in patients who underwent colorectal cancer resection surgery regarding the outcome of acute kidney injury. The main questions it aims to answer are: * is there a difference in acute kidney injury incidence in the two anesthetic modalities? * is there a difference in plasma creatinine between the two anesthetic modalities? * are there any patient characteristics or intraoperative factors that effect the incidence of acute kidney injury in either anesthetic modality? The study will analyze data from the CAN clinical trial database. (Cancer and Anesthesia: Survival After Radical Surgery - a Comparison Between Propofol or Sevoflurane Anesthesia, NCT01975064)

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.

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.

Reversibility of etomidate-induced contractile arrest through activation of myocardial autophagy

Project description:Anesthetic management of heart failure patients undergoing noncardiac surgery remains challenging due to cardiac suppressive properties of anesthetics. Due to varying electrophysiological properties, small and large animals are not good models for studying human myocardial anesthetic responses. Here we use hypertrophic (HCM), dilated (DCM) and healthy human induced pluripotent stem cells derived cardiomyocytes (hiPSC-CMs) to evaluate the cardiac suppression of propofol and etomidate. We demonstrate that propofol and etomidate act through GABAA receptors and contractile inhibition can occur without cell-cell junction. At supraphysiological dosage (100mM), we discovered that cardiac suppression induced by etomidate is reversible while propofol is not. Using transcriptome profiling, we uncover that etomidate was capable of inducing autophagy, likely through induction of cytosolic calcium. Lack of autophagy induction in propofol treated cardiomyocytes were associated with increased apoptosis. Together, we provide the robustness of using hiPSC-CMs as an in vitro cardiotoxicity platform for anesthetics. To delineate how etomidate confers cardioprotection during contraction inhibition, we performed transcriptome profiling on DCM hiPSC-CMs treated with either 10 μM propofol, 10 μM etomidate or DMSO control.

sevoflurane exposures on neonatal and adult mice,LC-MSMS

Project description:Sevoflurane is the most commonly used general anesthetic in pediatric surgery, but it has the potential to be neurotoxic. Previous research found that long-term or multiple sevoflurane exposures could cause cognitive deficits in newborn mice but not adult mice, whereas short-term or single inhalations had little effect on cognitive function at both ages. The mechanisms behind these effects, however, are unclear. In the current study, 6- and 60-day-old C57bl mice in the sevoflurane groups were given 3% sevoflurane plus 60% oxygen for three consecutive days, each lasting 2 hours, while those in the control group only got 60% oxygen. The cortex tissues were harvested on the 8th or 62nd day. The tandem mass tags (TMT)pro-based quantitative proteomics combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysi were applied to analyze the influences of multiple sevoflurane anesthesia on the cerebral cortex in mice with various ages. A total of 6247 proteins were measured using the combined quantitative proteomics methods of TMTpro-labeled and LC-MS/MS, 443 of which were associated to the age-dependent neurotoxic mechanism of repeated sevoflurane anesthesia. Our findings would help to further the mechanistic study of age-dependent anesthetic neurotoxicity and contribute to seek for effective protection in the developing brain under general anesthesia.

Project description:Although sevoflurane is one of the most commonly used inhalational anesthetic agent, the popularity of desflurane is increasing to a similar level. The main beneficial property of desflurane is the relatively fast emergence of the patient from the anesthetic state after halting its supply compared with anesthesia using other anesthetic agents. However, there has been no comprehensive comparison of the effects of these two anesthetic agents on alterations in liver gene expression profiles in animals, including humans, to assess the kinds of biological abnormalities/changes and their levels in the host. Thus, we compared alterations in the global gene expression profiles in the livers of rats subjected to inhalational anesthesia by sevoflurane or desflurane by a next-generation sequencing method.

Sevoflurane increases FKBP5 expression in microglia in the brains of aged marmosets and mice

Project description:Background: Inhalation anesthetics may trigger the hypothalamic–pituitary–adrenal (HPA) axis. FK-506 binding protein (FKBP5) is a critical factor that regulates the HPA axis and is associated with perioperative neurocognitive impairment. However, it is unclear how inhalation anesthetics affects the expression of FKBP5 in different neural cells in the brain. Methods: We used single-nucleus RNA sequencing to characterize hippocampal transcriptome profiles in the brains of aged marmosets and mice after sevoflurane anesthesia. Results: Higher levels of FKBP5 were found in the hippocampi of aged mice after sevoflurane anesthesia. Single nuclear RNA sequencing results from aged mice and marmosets showed that the increased expression of FKBP5 mainly occurred in microglia. The expression of FKBP5 in the hippocampi of aged marmosets and mice increased following long-term exposure to sevoflurane anesthesia. Additionally, the brains of these animals displayed a marked increase in the expression of FKBP5 in microglia after sevoflurane anesthesia. Conclusion: Long-term exposure to sevoflurane augments FKBP5 expression in the hippocampi of aged marmosets and mice, specifically in the microglia.
