Protein aggregation in the aging retina.
The age-related altered expression of neuron-related proteins as seen in other regions of the central nervous system is expected in the aging retina. Using immunohistochemical techniques, we characterized the distribution and aggregation of tau, βA4-amyloid, α-synuclein, and ubiquitin in human retina obtained from 19 enucleated eyes of patients aged 49 to 87 years and correlated the findings wi...
متن کاملAging of the Human Retina
The impact of aging on cell loss in the human retina was examined in foveal and temporal equatorial regions in eyes from 35 donors with ages spanning a 78-yr period from the second to the ninth decade of life. Equatorial cones and retinal pigment epithelial cells (RPE) decreased at uniform rates from the second to the ninth decade, 16 and 14 cells/mm/yr, respectively. Equatorial rods and cells ...
متن کاملBeta-catenin Forms Protein Aggregation at High Concentrations in HEK293TCells
Background: The canonical Wnt signal transduction (or the Wnt/β-catenin pathway) plays a crucial role in the development of animals and in carcinogenesis. Beta-catenin is the central component of this signaling pathway. The activation of Wnt/β-catenin signaling results in the cytoplasmic and nuclear accumulation of β-catenin. In the nucleus, β-catenin interacts with the TCF/LEF transcription fa...
متن کاملRole of Carbonyl Modifications on Aging-Associated Protein Aggregation
Protein aggregation is a common biological phenomenon, observed in different physiological and pathological conditions. Decreased protein solubility and a tendency to aggregate is also observed during physiological aging but the causes are currently unknown. Herein we performed a biophysical separation of aging-related high molecular weight aggregates, isolated from the bone marrow and splenic ...
متن کاملStress and aging induce distinct polyQ protein aggregation states.
Many age-related diseases are known to elicit protein misfolding and aggregation. Whereas environmental stressors, such as temperature, oxidative stress, and osmotic stress, can also damage proteins, it is not known whether aging and the environment impact protein folding in the same or different ways. Using polyQ reporters of protein folding in both Caenorhabditis elegans and mammalian cell cu...
