Abstract
BACKGROUND Repeated neonatal exposure to anesthetics may disturb neurodevelopment and cause neuropsychological disorders. The m6A modification participates in the gene regulation of neurodevelopment in mouse fetuses exposed to anesthetics. This study aims to explore the underlying molecular mechanisms of neurotoxicity after early-life anesthesia exposure. METHODS Mice were exposed to isoflurane (1.5%) or sevoflurane (2.3%) for 2 h daily during postnatal days (PND) 7-9. Sociability, spatial working memory, and anxiety-like behavior were assessed on PND 30-35. Synaptogenesis, epitranscriptome m6A, and the proteome of brain regions were evaluated on PND 21. RESULTS Both isoflurane and sevoflurane produced abnormal social behaviors at the juvenile age, with different sociality patterns in each group. Synaptogenesis in the hippocampal area CA3 was increased in the sevoflurane-exposed mice. Both anesthetics led to numerous persistent m6A-induced alterations in the brain, associated with critical metabolic, developmental, and immune functions. The proteins altered by isoflurane exposure were mainly associated with epilepsy, ataxia, and brain development. As for sevoflurane, the altered proteins were involved in social behavior. CONCLUSIONS Social interaction, the modulation patterns of the m6A modification, and protein expression were altered in an isoflurane or sevoflurane-specific way. Possible molecular pathways involved in brain impairment were revealed, as well as the mechanism underlying behavioral deficits following repeated exposure to anesthetics in newborns.

Abstract
Regulation of endoplasmic reticulum stress (ER) stress-induced apoptosis and nerve regeneration is a hopeful way for acute spinal cord injury (SCI). Sitagliptin (Sita) is one of dipeptidyl peptidase-4 (DPP-4) inhibitor, which is beneficial neurons damaged diseases. However, its protective mechanisms of avoiding nerve injury remain unclear. In this study, we further investigated the mechanism of the anti-apoptotic and neuroprotective effects of Sita in promoting locomotor recovery from SCI. In vivo results showed that Sita treatment reduced neural apoptosis caused by SCI. Moreover, Sita effectively attenuated the ER tress and associated apoptosis in rats with SCI. A striking feature was the occurrence of nerve fiber regeneration at the lesion site, which eventually led to significant locomotion recovery. In vitro results showed that the PC12 cell injury model induced by Thapsigargin (TG) also showed similar neuroprotective effects. Overall, sitagliptin showed potent neuroprotective effects by targeting the ER stress-induced apoptosis both in vivo and vitro, thus facilitating the regeneration of the injured spinal cord.

Acta Cir Bras 2021; 36:e360307. [PMID: 33978063 PMCID: PMC8112105 DOI: 10.1590/acb360307] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Accepted: 02/20/2021] [Indexed: 02/07/2023] Open
Abstract
Purpose To probe the mechanism of mild hypothermia combined with rutin in the
treatment of spinal cord injury (SCI). Methods Thirty rats were randomized into the following groups: control, sham, model,
mild hypothermia (MH), and mild hypothermia plus rutin (MH+Rutin). We used
modified Allen’s method to injure the spinal cord (T10) in rats, and then
treated it with MH or/and rutin immediately. BBB scores were performed on
all rats. We used HE staining for observing the injured spinal cord tissue;
ELISA for assaying TNF-α, IL-1β, IL-8, Myeloperoxidase (MPO), and
Malondialdehyde (MDA) contents; Dihydroethidium (DHE) for measuring the
reactive oxygen species (ROS) content; flow cytometry for detecting
apoptosis; and both RT-qPCR and Western blot for determining the expression
levels of TGF-β/Smad pathway related proteins (TGF-β, Smad2, and Smad3). Results In comparison with model group, the BBB score of MH increased to a certain
extent and MH+Rutin group increased more than MH group (p < 0.05). After
treatment with MH and MH+Rutin, the inflammatory infiltration diminished. MH
and MH+Rutin tellingly dwindled TNF-β, MDA and ROS contents (p < 0.01),
and minified spinal cord cell apoptosis. MH and MH+Rutin could patently
diminished TGF-β1, Smad2, and Smad3 expression (p < 0.01). Conclusions MH+Rutin can suppress the activation of TGF-β/Smad pathway, hence repressing
the cellular inflammatory response after SCI.
