Repurposing Drugs for Treatment of Age-Related Macular Degeneration

Adv Exp Med Biol. 2023;1415:73-77. doi: 10.1007/978-3-031-27681-1_12. ABSTRACT The need for new drugs to treat dry forms of age-related macular degeneration remains high. A promising approach is repurposing of FDA-approved medications to treat AMD. Databases containing medical and drug records allow for retroactive identification of drugs whose use correlates with reduced AMD diagnosis. This short […]

A Redox Homeostasis Modulatory Hydrogel with GLRX3+ Extracellular Vesicles Attenuates Disc Degeneration by Suppressing Nucleus Pulposus Cell Senescence

ACS Nano. 2023 Jul 11. doi: 10.1021/acsnano.3c01713. Online ahead of print. ABSTRACT Characterized by nucleus pulposus (NP) cell senescence and extracellular matrix (ECM) degradation, disc degeneration is a common pathology for various degenerative spinal disorders. To date, effective treatments for disc degeneration are absent. Here, we found that Glutaredoxin3 (GLRX3) is an important redox-regulating molecule […]

Identification and genetic characterization of Angiostrongylus cantonensis isolated from the human eye

Parasitol Res. 2023 Jul 11. doi: 10.1007/s00436-023-07922-3. Online ahead of print. ABSTRACT Angiostrongylus cantonensis, or the rat lungworm, is the causative agent of human angiostrongyliasis associated with eosinophilic meningitis or meningoencephalitis. Additionally, this nematode can cause ocular angiostrongyliasis, though this is rare. The worm can cause permanent damage to the affected eye and sometimes even […]

Depleted Hexokinase1 and lack of AMPKα activation favor OXPHOS-dependent energetics in Retinoblastoma tumors

Transl Res. 2023 Jul 5:S1931-5244(23)00108-1. doi: 10.1016/j.trsl.2023.07.001. Online ahead of print. ABSTRACT Lack of retinoblastoma protein (Rb) causes aggressive intraocular retinal tumors in children. Recently, Rb tumors have been shown to have a distinctly altered metabolic phenotype, such as reduced expression of glycolytic pathway proteins alongside altered pyruvate and fatty acid levels. In this study, […]

Impaired mitochondrial dynamics and removal of the damaged mitochondria in diabetic retinopathy

Front Endocrinol (Lausanne). 2023 Jun 21;14:1160155. doi: 10.3389/fendo.2023.1160155. eCollection 2023. ABSTRACT INTRODUCTION: Mitochondrial dynamic plays a major role in their quality control, and the damaged mitochondrial components are removed by autophagy. In diabetic retinopathy, mitochondrial fusion enzyme, mitofusin 2 (Mfn2), is downregulated and mitochondrial dynamic is disturbed resulting in depolarized and dysfunctional mitochondria. Our aim […]

Mitochondrial Dysfunction and Impaired Antioxidant Responses in Retinal Pigment Epithelial Cells Derived from a Patient with RCBTB1-Associated Retinopathy

Cells. 2023 May 10;12(10):1358. doi: 10.3390/cells12101358. ABSTRACT Mutations in the RCBTB1 gene cause inherited retinal disease; however, the pathogenic mechanisms associated with RCBTB1 deficiency remain poorly understood. Here, we investigated the effect of RCBTB1 deficiency on mitochondria and oxidative stress responses in induced pluripotent stem cell (iPSC)-derived retinal pigment epithelial (RPE) cells from control subjects […]

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 […]
