Protein oxidation and age-dependent alterations in calcium homeostasis.
Alterations in the capacity to maintain normal calcium homeostasis have been suggested to underlie the reduced cellular function characteristic of the aging process, and to predispose the senescent organism to a host of diverse pathologies including cancer, heart disease, and a range of muscle and neurodegenerative diseases. Therefore, critical to the eventual treatment of many age-related dise...

15 صفحه اولCD98hc (SLC3A2) regulation of skin homeostasis wanes with age
Skin aging is linked to reduced epidermal proliferation and general extracellular matrix atrophy. This involves factors such as the cell adhesion receptors integrins and amino acid transporters. CD98hc (SLC3A2), a heterodimeric amino acid transporter, modulates integrin signaling in vitro. We unravel CD98hc functions in vivo in skin. We report that CD98hc invalidation has no appreciable effect ...
متن کاملImplications of altered iron homeostasis for age-related macular degeneration.
Reactive oxygen species (ROS) may contribute to the pathogenesis of age-related macular degeneration (AMD) and they can be produced in the Fenton reaction catalyzed by Fe3+ ions. Therefore, altered homeostasis of iron in the retina may be the source of ROS and its damage resulting in clinically detectable AMD symptoms. The results of some post mortem research indicate a higher concentration of ...
متن کاملAge-dependent phosphate homeostasis is regulated by a circulating factor.
To evaluate the age-dependent phosphate homeostasis, we studied the serum inorganic phosphate (P(i)) concentration in 78 recipients, aged 5-25 years, a year after renal transplantation (RT). The significant age-dependent decline of the serum P(i) concentration was observed in recipients (p < 0.0001) as well as in normal children. Our study revealed that a circulating factor may play a central r...
