Downregulation of HOTAIR reduces neuronal pyroptosis by targeting miR-455-3p/NLRP1 axis in propofol-treated neurons in vitro.

by SmartTots | Apr 28, 2022 | Research Articles

Abstract Propofol is one of the most common intravenous anesthetics which may cause neuronal cell death in young mice. HOX transcript antisense RNA (HOTAIR) was abnormally expressed in neurodegenerative diseases. However, the effect of HOTAIR on propofol-induced...

MiRNA-384-5p targets GABRB1 to regulate ketamine-Induced Neurotoxicity in Neurons.

by SmartTots | Apr 28, 2022 | Research Articles

Abstract Aim: Ketamine is an anesthetic adjunct widely applied in the clinic that can induce hippocampal neurodegeneration in the brain. MicroRNAs (miRNAs) have been shown to be related to the regulation of ketamine-mediated neurotoxicity. This investigation aimed to...

Identification of microRNA/target gene in the dentate gyrus of 7 day old mice following isoflurane exposure.

by SmartTots | Apr 28, 2022 | Research Articles

Abstract Studies on rodents and nonhuman primates suggest that exposure to anesthetics, particularly in the young brain, is associated with neuronal apoptosis as well as hippocampal‑dependent cognitive dysfunction. Disruption of the development of dentate gyrus may...

Repeated neonatal exposure to sevoflurane induces age-dependent impairments in cognition and synaptic plasticity in mice.

by SmartTots | Apr 28, 2022 | Research Articles

Abstract Background Sevoflurane is a volatile anesthetic that is widely used in pediatric anesthesia due to its low toxicity. However, whether neonatal exposure to sevoflurane induces long-lasting cognitive impairment remains unclear. It has reported that neuronal...

Sevoflurane-Induced Apoptosis in the Mouse Cerebral Cortex Follows Similar Characteristics of Physiological Apoptosis.

by SmartTots | Apr 28, 2022 | Research Articles

Abstract General anesthetics are capable of inducing neuronal apoptosis during the rapid synaptogenesis of immature mammalian brains. In this vulnerable time window, physiological apoptosis also occurs to eliminate excess and inappropriately integrated neurons. We...
