Omega-3 fatty acids promote neuroprotection, decreased apoptosis and reduced glial cell activation in the retina of a mouse model of OPA1-related autosomal dominant optic atrophy

Exp Eye Res. 2022 Feb;215:108901. doi: 10.1016/j.exer.2021.108901. Epub 2021 Dec 20. ABSTRACT The purpose of this study was to evaluate the neuroprotective effects of omega-3 polyunsaturated fatty acid (ω3-PUFA) supplementation in a mouse model of OPA1-associated autosomal dominant optic atrophy (ADOA). The blood level of arachidonic acid (AA) and eicosapentaenoic acid (EPA) served to adjust […]

Autosomal dominant optic atrophy: A novel treatment for OPA1 splice defects using U1 snRNA adaption

Mol Ther Nucleic Acids. 2021 Oct 21;26:1186-1197. doi: 10.1016/j.omtn.2021.10.019. eCollection 2021 Dec 3. ABSTRACT Autosomal dominant optic atrophy (ADOA) is frequently caused by mutations in the optic atrophy 1 (OPA1) gene, with haploinsufficiency being the major genetic pathomechanism. Almost 30% of the OPA1-associated cases suffer from splice defects. We identified a novel OPA1 mutation, c.1065+5G>A, […]

Induced Pluripotent Stem Cells for Inherited Optic Neuropathies-Disease Modeling and Therapeutic Development

J Neuroophthalmol. 2022 Mar 1;42(1):35-44. doi: 10.1097/WNO.0000000000001375. Epub 2021 Sep 30. ABSTRACT BACKGROUND: Inherited optic neuropathies (IONs) cause progressive irreversible visual loss in children and young adults. There are limited disease-modifying treatments, and most patients progress to become severely visually impaired, fulfilling the legal criteria for blind registration. The seminal discovery of the technique for […]

Red Light Irradiation In Vivo Upregulates DJ-1 in the Retinal Ganglion Cell Layer and Protects against Axotomy-Related Dendritic Pruning

Int J Mol Sci. 2021 Aug 4;22(16):8380. doi: 10.3390/ijms22168380. ABSTRACT Retinal ganglion cells (RGCs) undergo dendritic pruning in a variety of neurodegenerative diseases, including glaucoma and autosomal dominant optic atrophy (ADOA). Axotomising RGCs by severing the optic nerve generates an acute model of RGC dendropathy, which can be utilized to assess the therapeutic potential of […]

Vision-related quality of life and visual ability in patients with autosomal dominant optic atrophy

Acta Ophthalmol. 2022 Nov;100(7):797-804. doi: 10.1111/aos.15102. Epub 2022 Feb 10. ABSTRACT PURPOSE: The purpose of the study was to evaluate vision-related quality of life and visual ability in patients with OPA1 autosomal dominant optic atrophy (ADOA). METHODS: This cross-sectional, observational study included 145 participants with a mutation in the OPA1 gene associated with ADOA, 63 […]

OPA1 Modulates Mitochondrial Ca2+ Uptake Through ER-Mitochondria Coupling

Front Cell Dev Biol. 2022 Jan 3;9:774108. doi: 10.3389/fcell.2021.774108. eCollection 2021. ABSTRACT Autosomal Dominant Optic Atrophy (ADOA), a disease that causes blindness and other neurological disorders, is linked to OPA1 mutations. OPA1, dependent on its GTPase and GED domains, governs inner mitochondrial membrane (IMM) fusion and cristae organization, which are central to oxidative metabolism. Mitochondrial […]

Knee osteoarthritis accelerates amyloid beta deposition and neurodegeneration in a mouse model of Alzheimer’s disease

Mol Brain. 2023 Jan 2;16(1):1. doi: 10.1186/s13041-022-00986-9. ABSTRACT Knee osteoarthritis (OA) is characterized by knee cartilage degeneration and secondary bone hyperplasia, resulting in pain, stiffness, and gait disturbance. The relationship between knee OA and neurodegenerative diseases is still unclear. This study used an Alzheimer’s disease (AD) mouse model to observe whether osteoarthritis accelerates dementia progression […]

The effect of serifs and stroke contrast on low vision reading

Acta Psychol (Amst). 2023 Feb;232:103810. doi: 10.1016/j.actpsy.2022.103810. Epub 2022 Dec 21. ABSTRACT PURPOSE: Patients with low vision are generally recommended to use the same fonts as individuals with normal vision. However, we are yet to fully understand whether stroke width and serifs (small ornamentations at stroke endings) can increase readability. This study’s purpose was to […]

Expectation-Maximization-Based Simultaneous Localization and Mapping for Millimeter-Wave Communication Systems

Sensors (Basel). 2022 Sep 14;22(18):6941. doi: 10.3390/s22186941. ABSTRACT In this paper, we proposed a novel expectation-maximization-based simultaneous localization and mapping (SLAM) algorithm for millimeter-wave (mmW) communication systems. By fully exploiting the geometric relationship among the access point (AP) positions, the angle difference of arrival (ADOA) from the APs and the mobile terminal (MT) position, and […]
