The Anti-Aging Hormone Klotho Promotes Retinal Pigment Epithelium Cell Viability and Metabolism by Activating the AMPK/PGC-1α Pathway

Antioxidants (Basel). 2023 Feb 5;12(2):385. doi: 10.3390/antiox12020385. ABSTRACT Initially discovered by Makuto Kuro-o in 1997, Klotho is a putative aging-suppressor gene when overexpressed and accelerates aging when deleted in mice. Previously, we showed that α-Klotho regulates retinal pigment epithelium (RPE) functions and protects against oxidative stress. However, the mechanisms by which Klotho influences RPE and […]

TRAP1 Is Expressed in Human Retinal Pigment Epithelial Cells and Is Required to Maintain their Energetic Status

Antioxidants (Basel). 2023 Feb 4;12(2):381. doi: 10.3390/antiox12020381. ABSTRACT Age-related macular degeneration (AMD) is the leading cause of severe vision loss and blindness in elderly people worldwide. The damage to the retinal pigment epithelium (RPE) triggered by oxidative stress plays a central role in the onset and progression of AMD and results from the excessive accumulation […]

FDX1-dependent and independent mechanisms of elesclomol-mediated intracellular copper delivery

Proc Natl Acad Sci U S A. 2023 Mar 7;120(10):e2216722120. doi: 10.1073/pnas.2216722120. Epub 2023 Feb 27. ABSTRACT Recent studies have uncovered the therapeutic potential of elesclomol (ES), a copper-ionophore, for copper deficiency disorders. However, we currently do not understand the mechanism by which copper brought into cells as ES-Cu(II) is released and delivered to cuproenzymes […]

Short communication: unique metabolic signature of proliferative retinopathy in the tear fluid of diabetic patients with comorbidities – preliminary data for PPPM validation

EPMA J. 2023 Feb 22;14(1):1-9. doi: 10.1007/s13167-023-00318-4. Online ahead of print. ABSTRACT Type 2 diabetes (T2DM) defined as the adult-onset type that is primarily not insulin-dependent, comprises over 95% of all diabetes mellitus (DM) cases. According to global records, 537 million adults aged 20-79 years are affected by DM that means at least 1 out […]
