Hereditary Optic Neuropathies: A Systematic Review on the Interplay between Biomaterials and Induced Pluripotent Stem Cells
Bioengineering (Basel). 2024 Jan 3;11(1):52. doi: 10.3390/bioengineering11010052. ABSTRACT Hereditary optic neuropathies (HONs) such as dominant optic atrophy (DOA) and Leber Hereditary Optic Neuropathy (LHON) are mitochondrial diseases characterized by a degenerative loss of retinal ganglion cells (RGCs) and are a cause of blindness worldwide. To date, there are only limited disease-modifying treatments for these disorders. […]
Chronic Sleep Deprivation Impairs Visual Functions via Oxidative Damage in Mice
Am J Pathol. 2024 Feb;194(2):307-320. doi: 10.1016/j.ajpath.2023.11.004. ABSTRACT Sleep deprivation (SD) is a global public health burden, and has a detrimental role in the nervous system. Retina is an important part of the central nervous system; however, whether SD affects retinal structures and functions remains largely unknown. Herein, chronic SD mouse model indicated that loss […]
Elevated cholesterol in ATAD3 mutants is a compensatory mechanism that leads to membrane cholesterol aggregation
Brain. 2024 Jan 18:awae018. doi: 10.1093/brain/awae018. Online ahead of print. ABSTRACT Aberrant cholesterol metabolism causes neurological disease and neurodegeneration, and mitochondria have been linked to perturbed cholesterol homeostasis via the study of pathological mutations in the ATAD3 gene cluster. However, whether the cholesterol changes were compensatory or contributory to the disorder was unclear, nor were […]
Stress granules affect the dual PI3K/mTOR inhibitor response by regulating the mitochondrial unfolded protein response
Cancer Cell Int. 2024 Jan 18;24(1):38. doi: 10.1186/s12935-024-03210-x. ABSTRACT Drug resistance remains a challenge in ovarian cancer. In addition to aberrant activation of relevant signaling pathways, the adaptive stress response is emerging as a new spotlight of drug resistance in cancer cells. Stress granules (SGs) are one of the most important features of the adaptive […]
Neuroimaging changes in the pregeniculate visual pathway and chiasmal enlargement in Leber hereditary optic neuropathy
Br J Ophthalmol. 2024 Jan 17:bjo-2023-324628. doi: 10.1136/bjo-2023-324628. Online ahead of print. ABSTRACT PURPOSE: To describe the pattern of MRI changes in the pregeniculate visual pathway in Leber hereditary optic neuropathy (LHON). METHOD: This retrospective observational study enrolled 60 patients with LHON between January 2015 and December 2021. The abnormal MRI features seen in the […]
Glutamine metabolism-related genes and immunotherapy in nonspecific orbital inflammation were validated using bioinformatics and machine learning
BMC Genomics. 2024 Jan 17;25(1):71. doi: 10.1186/s12864-023-09946-6. ABSTRACT BACKGROUND: Nonspecific orbital inflammation (NSOI) is an idiopathic, persistent, and proliferative inflammatory condition affecting the orbit, characterized by polymorphous lymphoid infiltration. Its pathogenesis and progression have been linked to imbalances in tumor metabolic pathways, with glutamine (Gln) metabolism emerging as a critical aspect in cancer. Metabolic reprogramming […]
Homocysteine and mitochondrial quality control in diabetic retinopathy
Eye Vis (Lond). 2024 Jan 16;11(1):5. doi: 10.1186/s40662-023-00362-1. ABSTRACT BACKGROUND: Diabetic retinopathy is a progressive disease, and one of the key metabolic abnormalities in the pathogenesis of diabetic retinopathy, mitochondrial damage, is also influenced by the duration of hyperglycemia. Mitochondrial quality control involves a coordination of mitochondrial dynamics, biogenesis and removal of the damaged mitochondria. […]
Mitochondrial Disruption Nanosystem Simultaneously Depressed Programmed Death Ligand-1 and Transforming Growth Factor-β to Overcome Photodynamic Immunotherapy Resistance
ACS Nano. 2024 Jan 16. doi: 10.1021/acsnano.3c10117. Online ahead of print. ABSTRACT Currently, limited photosensitizers possess the capacity to reverse tumor hypoxia and reduce programmed death ligand-1 (PD-L1) and transforming growth factor-β (TGF-β) expression simultaneously, hindering the perfect photodynamic therapy (PDT) effect due to acquired immune resistance and the tumor hypoxic microenvironment. To tackle these […]
METTL4 mediated-N6-methyladenosine promotes acute lung injury by activating ferroptosis in alveolar epithelial cells
Free Radic Biol Med. 2024 Jan 13:S0891-5849(24)00013-3. doi: 10.1016/j.freeradbiomed.2024.01.013. Online ahead of print. ABSTRACT Sepsis-induced acute lung injury has been deemed to be an life-threatening pulmonary dysfunction caused by a dysregulated host response to infection. The modification of N6-Methyladenosine (m6A) is implicated in several biological processes, including mitochondrial transcription and ferroptosis. Ferroptosis is an iron-dependent […]
RTN4IP1-associated non-syndromic optic neuropathy and rod-cone dystrophy
Ophthalmic Genet. 2024 Jan 15:1-5. doi: 10.1080/13816810.2024.2303683. Online ahead of print. ABSTRACT BACKGROUND: Biallelic variants in RTN4IP1 are a well-established cause of syndromic and nonsyndromic early-onset autosomal recessive optic neuropathy. They have more recently been reported to cause a concomitant but later-onset rod-cone dystrophy with or without syndromic features. METHODS: A comprehensive evaluation was performed […]
