Abstract
Atherosclerosis (AS) represents a prevalent initiating factor for cardiovascular events. Insulin-like growth factor 2 mRNA binding protein 3 (IGF2BP3) is an oncofetal RNA-binding protein that participates in cardiovascular diseases. This work aimed to elaborate the effects of IGF2BP3 on AS and the probable mechanism by using an oxidized low-density lipoprotein (ox-LDL)-induced human umbilical vein endothelial cells (HUVECs) model. Results indicated that IGF2BP3 expression was declined in the blood of AS patients and ox-LDL-induced HUVECs. IGF2BP3 elevation alleviated ox-LDL-provoked viability loss, apoptosis, oxidative DNA damage and endothelial dysfunction in HUVECs. Moreover, IGF2BP3 bound SESN1 and stabilized SESN1 mRNA. Furthermore, SESN1 interference reversed the impacts of IGF2BP3 overexpression on the apoptosis, oxidative DNA damage and endothelial dysfunction of ox-LDL-challenged HUVECs. Additionally, the activation of Nrf2 signaling mediated by IGF2BP3 up-regulation in ox-LDL-treated HUVECs was blocked by SESN1 absence. Collectively, SESN1 stabilized by IGF2BP3 might protect against AS by activating Nrf2 signaling.

Eur J Neurosci 2024; 59:208-219. [PMID: 38105520 DOI: 10.1111/ejn.16218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 11/20/2023] [Accepted: 11/22/2023] [Indexed: 12/19/2023]
Abstract
Postoperative cognitive dysfunction (POCD) is a prevalent central nervous system complication predominantly observed in elderly patients. Sevoflurane, a general anaesthetic agent, has been implicated in the development of POCD, yet the underlying regulatory mechanisms potentially involving Sestrin1 (SESN1), a stress-responsive protein that plays a critical role in cellular homeostasis and protection against stress-induced damage, including oxidative stress and DNA damage, remain elusive. This study endeavoured to elucidate the impact of SESN1 on sevoflurane-induced cognitive impairment in rats. Employing a model in which SESN1 was transfected into SD male rats and cognitive dysfunction was induced by sevoflurane. The Morris Water Maze test was used for behavioural evaluation, Enzyme-Linked Immunosorbent Assay, Western blotting and immunofluorescence were applied to assess the influence of SESN1 on the inflammatory response and mitophagy in the rat hippocampus. The study further aimed to uncover the putative mechanism by which SESN1, through SIRT1, might modulate cognitive function. Concurrently, levels of malondialdehyde, superoxide dismutase and mitochondrially produced ATP within the rat hippocampus were quantified. Experimental outcomes suggested that SESN1 overexpression significantly mitigated the deleterious effects of sevoflurane anaesthesia, ameliorated neuroinflammation and inflammasome activation, modified mitochondrial function and facilitated mitophagy. Additionally, SESN1, via the activation of SIRT1, may suppress inflammasome activation and mitochondrial dysfunction. Collectively, these findings underscore SESN1's integral role in counteracting sevoflurane-induced cognitive impairment, impeding inflammasome activation, enhancing mitochondrial function and fostering mitophagy, which appear to be intricately linked to SESN1-mediated SIRT1 activation. SESN1 is a novel therapeutic target for POCD, potentially advancing neuroprotective strategies in clinical settings.

Abstract
BACKGROUND Atherosclerosis (AS) is a disease characterized by the disorder of lipid metabolism and the formation of atherosclerotic plaques in the arterial wall, leading to arterial stenosis. Sestrins 1 (SESN1) plays an important regulatory role in AS, but the specific regulatory mechanism is still unclear. METHODS ApoE-/- mouse models of AS were constructed. After overexpressing SESN1, oil red O staining was used to detect the degree of aortic plaque. HE staining detected the endothelial damage of the surrounding tissues. ELISA was used to detect the levels of vascular inflammation and oxidative stress. The iron metabolism in vascular tissues was detected by immunofluorescence. The expressions of SESN1 and ferroptosis-related proteins were detected by western blot. In the oxidized low-density lipoprotein (ox-LDL)-induced injury model in human umbilical vein endothelial cells (HUVECs), CCK8, ELISA, immunofluorescence and western blot were respectively used to detect cell viability, inflammatory response, oxidative stress and ferroptosis. The regulatory mechanism of SESN1 on endothelial ferroptosis in AS was further explored following the addition of P21 inhibitor UC2288. RESULTS Overexpression of SESN1 could inhibit the extent of the plaque and reduce the endothelial injury of plaque tissues in AS mice. In both mouse and cell models of AS, SESN1 overexpression inhibited inflammatory response, oxidative stress response, and endothelial ferroptosis. The inhibitory effect of SESN1 on endothelial ferroptosis might be achieved through activation of P21. CONCLUSION SESN1 overexpression plays an inhibitory role in vascular endothelial ferroptosis through the activation of P21 in AS.

Abstract
AIM The progression of atherosclerosis can lead to the occurrence of multiple cardiovascular diseases (coronary heart disease, etc.). E prostanoid receptor-3 (EP3) is known to participate in the progression of atherosclerosis. This study aimed to investigate the mechanism by which EP3 modulates the development of atherosclerosis. METHODS AND RESULTS ApoE-/- mice were used to construct in vivo model of atherosclerosis. Human aortic smooth muscle cells (HASMCs) were stimulated with oxidized low-density lipoprotein (ox-LDL) to construct in vitro model of atherosclerosis. mRNA expressions were assessed by qRT-PCR, and western blot was applied to assess the protein levels. CCK-8 assay was applied to assess the cell viability. The inflammatory cytokines levels were assessed by enzyme-linked immunosorbent assay, and flow cytometry was applied to assess cell apoptosis. In vivo experiment was constructed to investigate the impact of EP3 in atherosclerosis development. L-798106 (EP3 inhibitor) significantly inhibited the levels of pro-inflammatory cytokines in atherosclerosis in vivo. EP3 inhibitor (L-798106) significantly reversed ox-LDL-caused HASMCs injury via inhibiting the apoptosis and inflammatory responses (P < 0.05). The levels of interleukin-17 (IL-17) and intercellular adhesion molecule-1 (ICAM-1) in HASMCs were elevated by ox-LDL, whereas L-798106 or knockdown of cyclic AMP (cAMP) response element-binding protein (CREB) notably restored this phenomenon (P < 0.05). EP3 overexpression further aggravated ox-LDL-induced inflammation in HASMCs, and EP3 up-regulated the levels of IL-17 and ICAM-1 in ox-LDL-treated HASMCs (P < 0.05). EP3 up-regulation promoted the inflammatory responses in ox-LDL-treated HASMCs through mediation of cAMP/protein kinase A (PKA)/CREB/IL-17/ICAM-1 axis (P < 0.05). CONCLUSIONS EP3 inhibitor alleviates ox-LDL-induced HASMC inflammation via mediation of cAMP/PKA/CREB/IL-17/ICAM-1 axis. Our study might shed new lights on discovering novel strategies against atherosclerosis.

ANNALS OF TRANSLATIONAL MEDICINE 2022; 10:1383.

Abstract
Background Oxidative low-density lipoprotein (ox-LDL)-induced endothelial cell damage is a major risk factor for atherosclerosis and its related cardiovascular diseases. The G0/G1 switch gene 2 (G0S2) is a multifunctional protein which has been poorly studied in atherosclerosis. Methods In this study, ox-LDL was utilized to construct a human aortic endothelial cell (HAEC) injury model. Results It was found that ox-LDL impaired cell viability, augmented lactate dehydrogenase (LDH) release, and reduced G0S2 levels in HAECs in a dose-dependent manner. Further, G0S2 overexpression improved the viability and restrained apoptosis of HAECs treated by ox-LDL. Conversely, G0S2 depletion decreased the viability and aggravated apoptosis of HAECs treated by ox-LDL. At the molecular level, G0S2 overexpression significantly increased the secretion of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPH-Px), promoted intracellular reactive oxygen species (ROS) production and malondialdehyde (MDA) content in HAECs under either normal or ox-LDL conditions. Meanwhile, the ox-LDL-induced mitochondrial dysfunction, as demonstrated by decreased mitochondrial membrane potential, translocation of mitochondrial cytochrome c (Cyt-c) to the cytoplasm, and activation of caspase-3 and caspase-9, was significantly reversed by G0S2 overexpression. In addition, G0S2 overexpression promoted the activation of AMP-activated protein kinase (AMPK) and increased the expression of nuclear factor erythroid-2-related factor-2 (Nrf2), sirtuin 1 (SIRT1) and heme oxygenase 1 (HO-1) under normal and ox-LDL conditions. Conclusions This study demonstrated that G0S2 protects against ox-LDL-induced vascular endothelial cell injury by regulating oxidative damage and mitochondrial homeostasis and may be a promising target for the treatment of atherosclerosis.
