Visual Loss from Leber’s Optic Neuropathy Presenting in a 76-Year-Old Man with the 14484 Mutations

Neuroophthalmology. 2025 May 19;50(2):159-166. doi: 10.1080/01658107.2025.2487842. eCollection 2026. ABSTRACT Leber’s Hereditary Optic Neuropathy (LHON) is an important hereditary optic neuropathy that typically causes bilateral visual loss, predominantly in male patients. While it usually manifests in young adults, it can uncommonly present in older individuals without a family history, potentially leading to diagnostic confusion. The mechanisms […]

Optic Atrophy Associated With a Mitochondrial G8363A Mutation in a Family

Clin Genet. 2026 Mar 18. doi: 10.1111/cge.70152. Online ahead of print. ABSTRACT We report a rare family of optic atrophy diseases associated with mitochondrial DNA G8363A transfer ribonucleic acid (RNA) cleavage mutations. This family does not exhibit the characteristic symptoms of myoclonic epilepsy or cutaneous lipomas, but instead presents with bilateral optic atrophy. The clinical […]

A Case Report of Late-Onset Leber’s Hereditary Optic Neuropathy Diagnosed Following Vision Loss After Cataract Surgery

Neuroophthalmology. 2025 May 6;50(2):180-185. doi: 10.1080/01658107.2025.2495295. eCollection 2026. ABSTRACT Leber’s Hereditary Optic Neuropathy (LHON) is a rare mitochondrial disorder characterized by acute to subacute vision loss, predominantly affecting young males. We report a case of a 65-year-old male diagnosed with late-onset LHON after experiencing significant vision decline following cataract surgery. The patient initially presented with […]

Research Prospects for the Mitochondria in Glaucoma: A Bibliometric Analysis

Curr Med Chem. 2026 Mar 11. doi: 10.2174/0109298673417791251204121930. Online ahead of print. ABSTRACT BACKGROUND: Growing evidence implicates mitochondrial dysfunction as a pivotal contributor to glaucoma pathogenesis through oxidative stress, autophagy, and apoptotic pathways. However, systematic analyses of research collaboration patterns, key themes, and emerging trends in this field remain limited. METHODS: We retrieved relevant publications […]

1β,6α-Dihydroxyeudesm-4(15)-ene Protects Against MPP+-Induced Cytotoxicity in SH-SY5Y Cells: An In Vitro Model of Parkinson’s Disease

J Med Food. 2026 Feb;29(2):71-81. doi: 10.1177/1096620X261428649. Epub 2026 Mar 16. ABSTRACT Parkinson’s disease (PD) is a neurodegenerative disorder characterized by the progressive degeneration of the nigrostriatal dopaminergic pathway, which regulates body movements. 1-Methyl-4-phenylpyridinium (MPP+) is a widely used neurotoxin for studying the neurodegenerative process in PD models. 1β,6α-Dihydroxyeudesm-4(15)-ene (DE) is a sesquiterpene isolated from […]

TAZ (Wwtr1) deficiency leads to ER stress and mitochondrial dysfunction in a mouse model of Fuchs’ endothelial corneal dystrophy

bioRxiv [Preprint]. 2026 Feb 19:2026.02.17.706456. doi: 10.64898/2026.02.17.706456. ABSTRACT Fuchs’ endothelial corneal dystrophy (FECD) impacts over 300 million individuals worldwide with corneal transplantation as the primary treatment. There is a dire need to establish non-surgical alternatives which are dependent on mouse models. Transcriptional co-activator with PDZ-binding motif (TAZ, encoded by Wwtr1) is a mechanotransducer implicated in […]

Lactate-Lactylation Axis as an Emerging Metabolic-Epigenetic Pathway in Diabetic Microvascular Complications

Ageing Res Rev. 2026 Mar 12:103100. doi: 10.1016/j.arr.2026.103100. Online ahead of print. ABSTRACT Lactate, once viewed merely as a glycolytic byproduct, is now recognized as a key signaling molecule and epigenetic regulator through the recently identified post-translational modification known as lactylation. In diabetic microvascular complications, including diabetic retinopathy (DR), diabetic kidney disease (DKD), and diabetic […]

Characterization of the Effects of a Humanin Fragment Peptide (HNF14) in Age-Related Macular Degeneration

J Clin Med. 2026 Feb 24;15(5):1686. doi: 10.3390/jcm15051686. ABSTRACT Background: Age-related macular degeneration (AMD) is a leading cause of vision loss and is strongly associated with mitochondrial dysfunction in retinal pigment epithelial cells. Mitochondrial-derived peptides, including Humanin and its analogs, have demonstrated cytoprotective effects in AMD-related cellular models. However, the effects of shorter Humanin-derived fragments […]

COG5 deficiency disrupts cellular copper homeostasis and underlies the impaired mitochondrial OXPHOS function

PLoS Genet. 2026 Mar 13;22(3):e1012076. doi: 10.1371/journal.pgen.1012076. eCollection 2026 Mar. ABSTRACT COG5, a subunit of the conserved oligomeric Golgi (COG) complex, plays a critical role in retrograde trafficking within the Golgi apparatus. Dysfunction of COG5 is associated with various human disorders, yet the underlying pathogenic mechanisms remain poorly understood. To investigate the mechanisms, we conducted […]
