A p-Tyr42 RhoA Inhibitor Promotes the Regeneration of Human Corneal Endothelial Cells by Ameliorating Cellular Senescence
Antioxidants (Basel). 2023 May 30;12(6):1186. doi: 10.3390/antiox12061186. ABSTRACT The development of treatment strategies for human corneal endothelial cells (hCECs) disease is necessary because hCECs do not regenerate in vivo due to the properties that are similar to senescence. This study is performed to investigate the role of a p-Tyr42 RhoA inhibitor (MH4, ELMED Inc., Chuncheon) […]

ABSTRACT PURPOSES: This work aimed to assess the possible role of TRIM25 in regulating hyperglycemia-induced inflammation, senescence, and oxidative stress in retinal microvascular endothelial cells, all of which exert critical roles in the pathological process of diabetic retinopathy. METHODS: The effects […]
Metformin inhibits methylglyoxal-induced retinal pigment epithelial cell death and retinopathy via AMPK-dependent mechanisms: Reversing mitochondrial dysfunction and upregulating glyoxalase 1
Redox Biol. 2023 Jun 15;64:102786. doi: 10.1016/j.redox.2023.102786. Online ahead of print. ABSTRACT Diabetic retinopathy (DR) is a major cause of blindness in adult, and the accumulation of advanced glycation end products (AGEs) is a major pathologic event in DR. Methylglyoxal (MGO), a highly reactive dicarbonyl compound, is a precursor of AGEs. Although the therapeutic potential […]
Three-Dimensional Spheroid Configurations and Cellular Metabolic Properties of Oral Squamous Carcinomas Are Possible Pharmacological and Pathological Indicators
Cancers (Basel). 2023 May 17;15(10):2793. doi: 10.3390/cancers15102793. ABSTRACT The objective of the current study was to elucidate the clinicopathological significance and appearance of in vitro three-dimension (3D) spheroid models of oral malignant tumors that were prepared from four pathologically different squamous cell carcinoma (OSCC; low-grade; SSYP and MO-1000, intermediate-grade; LEM2) and oral adenosquamous carcinoma (OASC; […]
miR-1273h-5p protects the human corneal epithelium against UVR-induced oxidative stress and apoptosis: Role of miR-1273h-5p in climatic droplet keratopathy
Exp Eye Res. 2023 Jun 17:109536. doi: 10.1016/j.exer.2023.109536. Online ahead of print. ABSTRACT Climatic droplet keratopathy (CDK) is characterized by an increased number of oil-like deposits on the most anterior corneal layers, which affect vision and can cause blindness. Environmental ultraviolet radiation (UVR) exposure is a major risk factor, but the underlying mechanism of CDK […]
Research progress on the mechanism of ferroptosis and its role in diabetic retinopathy
Front Endocrinol (Lausanne). 2023 Jun 1;14:1155296. doi: 10.3389/fendo.2023.1155296. eCollection 2023. ABSTRACT Ferroptosis is iron-dependent regulatory cell death (RCD). Morphologically, ferroptosis is manifested as mitochondrial atrophy and increased mitochondrial membrane density. Biochemically, ferroptosis is characterized by the depletion of glutathione (GSH), the inactivation of glutathione peroxidase 4 (GPX4), and an increase in lipid peroxides (LPO)and divalent […]
Complement-mediated inflammation and mitochondrial energy metabolism in the proteomic profile of myopic human corneas
J Proteomics. 2023 Jun 16:104949. doi: 10.1016/j.jprot.2023.104949. Online ahead of print. ABSTRACT Myopia is one of the most common causes of visual impairment worldwide. To identify proteins related to myopiagenesis, data-independent acquisition proteomic analysis was performed using corneal lenticules of myopic patients who underwent small incision lenticule extraction surgery. A total of 19 lenticules from […]
Rhein protects retinal Müller cells from high glucose-induced injury via activating the AMPK/Sirt1/PGC-1α pathway
J Recept Signal Transduct Res. 2023 Jun 18:1-10. doi: 10.1080/10799893.2023.2223319. Online ahead of print. ABSTRACT Oxidative stress, inflammation and apoptosis are important pathogenic factors of diabetic retinopathy (DR). In the current study, we aimed to evaluate the potential role of Rhein, a natural anthraquinone compound found in rhubarb, in high glucose (HG)-induced Müller cells (MIO-M1). […]
Titanium alloys with varying surface micro-area potential differences have antibacterial abilities and a favorable cellular response
Clin Oral Investig. 2023 Jun 17. doi: 10.1007/s00784-023-05115-x. Online ahead of print. ABSTRACT OBJECTIVES: Surface micro-area potential difference (MAPD) can achieve bacteriostatic performance independent of metal ion dissolution. To study the influence of MAPD on antibacterial properties and the cellular response, Ti-Ag alloys with different surface potentials were designed and prepared by changing the preparation […]
Evaluation of the role of Sigma 1 receptor and Cullin3 in retinal photoreceptor cells
Free Radic Biol Med. 2023 Jun 14:S0891-5849(23)00496-3. doi: 10.1016/j.freeradbiomed.2023.06.010. Online ahead of print. ABSTRACT Sigma 1 receptor (Sig1R), a pluripotent modulator of cell survival, is neuroprotective in models of retinal degeneration when activated by the high-affinity, high-specificity ligand (+)-pentazocine ((+)-PTZ). The molecular mechanisms of Sig1R-mediated retinal neuroprotection are under investigation. We previously reported that the […]
