Alleviation of Photoreceptor Degeneration Based on Fullerenols in rd1 Mice by Reversing Mitochondrial Dysfunction via Modulation of Mitochondrial DNA Transcription and Leakage
Small. 2023 Jul 5:e2205998. doi: 10.1002/smll.202205998. Online ahead of print. ABSTRACT Poor therapeutic outcomes of antioxidants in ophthalmologic clinical applications, including glutathione during photoreceptor degeneration in retinitis pigmentosa (RP), are caused by limited anti-oxidative capacity. In this study, fullerenols are synthesized and proven to be highly efficient in vitro radical scavengers. Fullerenol-based intravitreal injections significantly […]
CircRNA SCAR Improves High-Glucose-Induced Mitochondrial Dysfunction and Permeability Damage in Retinal Microvascular Endothelial Cells
Horm Metab Res. 2023 Jul 3. doi: 10.1055/a-2108-9820. Online ahead of print. ABSTRACT This study was designed to assess the role and mechanism of circRNA SCAR in human retinal microvascular endothelial cells (hRMVECs) treated with high glucose. Quantitative real-time polymerase chain reaction (qRT-PCR) and cell counting kit 8 (CCK-8) were used to detect the effects […]
Lanatoside C decelerates proliferation and induces apoptosis through inhibition of STAT3 and ROS-mediated mitochondrial membrane potential transformation in cholangiocarcinoma
Front Pharmacol. 2023 Jun 15;14:1098915. doi: 10.3389/fphar.2023.1098915. eCollection 2023. ABSTRACT Introduction: The incidence of cholangiocarcinoma (CCA) has increased worldwide in recent years. Given the poor prognosis associated with the current management approach of CCA, new therapeutic agents are warranted to improve the prognosis of this patient population. Methods: In this study, we extracted five cardiac […]
Oxidative Stress-Involved Mitophagy of Retinal Pigment Epithelium and Retinal Degenerative Diseases
Cell Mol Neurobiol. 2023 Jul 1. doi: 10.1007/s10571-023-01383-z. Online ahead of print. ABSTRACT The retinal pigment epithelium (RPE) is a highly specialized and polarized epithelial cell layer that plays an important role in sustaining the structural and functional integrity of photoreceptors. However, the death of RPE is a common pathological feature in various retinal diseases, […]
Inhibition of DRP1-dependent mitochondrial fission by Mdivi-1 alleviates atherosclerosis through the modulation of M1 polarization
J Transl Med. 2023 Jun 30;21(1):427. doi: 10.1186/s12967-023-04270-9. ABSTRACT BACKGROUND: Inflammation and immune dysfunction with classically activated macrophages(M1) infiltration are important mechanisms in the progression of atherosclerosis (AS). Dynamin-related protein 1 (DRP1)-dependent mitochondrial fission is a novel target for alleviating inflammatory diseases. This study aimed to investigate the effects of DRP1 inhibitor Mdivi-1 on AS. […]
Immunobiology of a rationally-designed AAV2 capsid following intravitreal delivery in mice
Gene Ther. 2023 Jun 29. doi: 10.1038/s41434-023-00409-x. Online ahead of print. ABSTRACT Adeno-associated virus serotype 2 (AAV2) is a viral vector that can be used to deliver therapeutic genes to diseased cells in the retina. One strategy for altering AAV2 vectors involves the mutation of phosphodegron residues, which are thought to be phosphorylated/ubiquitinated in the […]
Progress in the Treatment of High Altitude Cerebral Edema: Targeting REDOX Homeostasis
J Inflamm Res. 2023 Jun 23;16:2645-2660. doi: 10.2147/JIR.S415695. eCollection 2023. ABSTRACT With the increasing of altitude activities from low-altitude people, the study of high altitude cerebral edema (HACE) has been revived. HACE is a severe acute mountain sickness associated with exposure to hypobaric hypoxia at high altitude, often characterized by disturbance of consciousness and ataxia. […]
Non-Pharmaceutical Interventions against COVID-19 Causing a Lower Trend in Age of LHON Onset
Genes (Basel). 2023 Jun 12;14(6):1253. doi: 10.3390/genes14061253. ABSTRACT Leber hereditary optic neuropathy (LHON) is a monogenic but multifactorial disease vulnerable to environmental triggers. Little is known about how LHON onset changed during the COVID-19 pandemic and how non-pharmaceutical interventions (NPHIs) against COVID-19 impact LHON onset. One hundred and forty-seven LHON patients with the m.11778G>A mutation […]
Role of NADPH Oxidase 4 in Corneal Endothelial Cells Is Mediated by Endoplasmic Reticulum Stress and Autophagy
Antioxidants (Basel). 2023 Jun 7;12(6):1228. doi: 10.3390/antiox12061228. ABSTRACT Human corneal-endothelial cells (hCEnCs) are located on the inner layer of the cornea. Injury to CEnCs leads to permanent corneal edema, requiring corneal transplantation. NADPH oxidase 4 (NOX4) has been reported to be implicated in the pathogenesis of CEnCs diseases. Thus, we investigated the role of NOX4 […]
A p-Tyr42 RhoA Inhibitor Promotes the Regeneration of Human Corneal Endothelial Cells by Ameliorating Cellular Senescence
Antioxidants (Basel). 2023 May 30;12(6):1186. doi: 10.3390/antiox12061186. ABSTRACT The development of treatment strategies for human corneal endothelial cells (hCECs) disease is necessary because hCECs do not regenerate in vivo due to the properties that are similar to senescence. This study is performed to investigate the role of a p-Tyr42 RhoA inhibitor (MH4, ELMED Inc., Chuncheon) […]
