Mitochondria in Corneal Physiology and Pathology: A Mechanistic Perspective
Prog Retin Eye Res. 2025 Dec 23:101432. doi: 10.1016/j.preteyeres.2025.101432. Online ahead of print. ABSTRACT The cornea is the eye’s outermost protective and refractive barrier whose physiological homeostasis depends on mitochondrial competence and dynamic stability. Mitochondrial dysfunctions are characterized by impaired electron transport chain efficiency, excessive reactive oxygen species generation, calcium dysregulation, and disrupted dynamics. Clinically, […]
Exercise-Induced Biomarker Modulation in Sarcopenia: From Inflamm-Aging to Muscle Regeneration
Sports (Basel). 2025 Dec 9;13(12):444. doi: 10.3390/sports13120444. ABSTRACT Sarcopenia is a progressive, age-related loss of skeletal muscle mass, strength, and function, strongly associated with frailty, disability, and chronic disease. Its pathogenesis involves chronic low-grade inflammation, hormonal imbalance, and impaired anabolic signaling, making biomarkers essential for diagnosis, prognosis, and intervention monitoring. This review systematically analyzes randomized […]
Enhancement of DJ-1/ERK1/2 signaling as a therapeutic strategy for diabetic keratopathy
Exp Eye Res. 2025 Dec 22;264:110820. doi: 10.1016/j.exer.2025.110820. Online ahead of print. ABSTRACT BACKGROUND: Diabetic keratopathy (DK) is a prevalent yet often overlooked complication of diabetes, marked by delayed corneal epithelial repair and impaired nerve regeneration. Despite its clinical significance, effective pharmacological interventions are still lacking, largely due to the limited understanding of its underlying […]
Corneal Sensory Nerves and Corneal Epithelial Cells Are in a Codependent Relationship
Eye Contact Lens. 2025 Dec 23. doi: 10.1097/ICL.0000000000001253. Online ahead of print. ABSTRACT The intraepithelial corneal nerves are a dense collection of sensory axons that consist of the intraepithelial basal nerves and intraepithelial nerve terminals. The plasma membranes of corneal epithelial cells ensheathe the nerves providing them mechanical support. The nerves, in turn, release trophic […]
A novel single-cell level evaluation method for corneal endothelial cell function
NPJ Digit Med. 2025 Dec 22. doi: 10.1038/s41746-025-02239-0. Online ahead of print. ABSTRACT Approximately 10 million people worldwide suffer from corneal diseases, with endothelial dysfunction being a leading cause of blindness. Current morphological assessments lack sensitivity for detecting early corneal endothelial abnormalities. Here, we present a novel diagnostic framework that evaluates endothelial cell function at […]
Endocrine-disrupting effects of environmental BPS and PFOS on human brain organoid development
Front Endocrinol (Lausanne). 2025 Dec 4;16:1692333. doi: 10.3389/fendo.2025.1692333. eCollection 2025. ABSTRACT OBJECTIVE: Prenatal exposure to environmental endocrine-disrupting chemicals (EDCs) has been increasingly linked to neurodevelopmental impairment. Bisphenol S (BPS) and perfluoro-octane sulfonate (PFOS), two widely distributed EDCs detected in maternal and fetal tissues, raise concern due to their potential to interfere with brain development even […]
Ethanol and Cyanide: A Case Report on Toxic and Nutritional Optic Neuropathy Associated With Alcohol and Tobacco
Cureus. 2025 Nov 17;17(11):e97067. doi: 10.7759/cureus.97067. eCollection 2025 Nov. ABSTRACT Tobacco-alcohol amblyopia, an acquired optic neuropathy, is now classified as toxic and nutritional optic neuropathy (TNON). A 40-year-old man presented with gradual, painless, symmetrical visual loss and central scotomas. Pupillary reactions were normal, with no relative afferent pupillary defect (RAPD), though colour vision was markedly […]
AKAP1 regulates mitochondrial and synaptic homeostasis to enable neuroprotection and repair in retinal ganglion cell degeneration
bioRxiv [Preprint]. 2025 Nov 27:2025.11.24.689866. doi: 10.1101/2025.11.24.689866. ABSTRACT Glaucoma is a leading cause of irreversible blindness, characterized by progressive retinal ganglion cell (RGC) loss and optic nerve degeneration. Mitochondrial dysfunction plays a central role in this neurodegeneration, yet effective targeted therapies remain limited. Here, we identify the mitochondrial scaffold A-kinase anchoring protein 1 (AKAP1) as […]
DCLRE1 downregulated by SYVN1-mediated ubiquitination and degradation, weakening mitochondrial homeostasis protection in ARC formation
Exp Eye Res. 2025 Dec 18:110811. doi: 10.1016/j.exer.2025.110811. Online ahead of print. ABSTRACT DNA oxidative damage of lens epithelium cells (LECs) has been proved to be significantly related to age-related cataract (ARC). DCLRE1A, as a member of the DNA interstrand cross-links pathway, can repair damaged DNA. However, DCLRE1A has not been addressed in maintaining mitochondrial […]
Transcriptome-wide isoform and promoter remodeling in DM1 fibroblasts uncovered by long-read RNA sequencing
Genomics. 2025 Dec 16:111175. doi: 10.1016/j.ygeno.2025.111175. Online ahead of print. ABSTRACT Myotonic dystrophy type 1 (DM1) is characterized by sequestration of RNA-binding proteins and widespread transcriptomic dysregulation, yet isoform-level transcriptomic landscapes remain incompletely defined. Here, we performed integrated long-read (PacBio Iso-Seq) and short-read (Illumina RNA-seq) profiling of primary fibroblasts from DM1 patients and healthy controls. […]
