Aging tissues experience a progressive decline in homeostatic and regenerative capacities, which has been attributed to degenerative changes in tissue-specific stem cells, stem cell niches and systemic cues that regulate stem cell activity. Understanding the molecular pathways involved in this age-dependent deterioration of stem cell function will be critical for developing new therapies for diseases of aging that target the specific causes of age-related functional decline.
The discovery of autophagy-related ('ATG') proteins in the 1990s greatly advanced the mechanistic understanding of autophagy and clarified the fact that autophagy serves important roles in various biological processes.
This feed focuses on the role of the aging process on developing diabetes.
Age is associated with many metabolic disorders including cardiovascular diseases, type 2 diabetes, stroke and heart disease. The mediators in aging process have been suggested to play a part in the cellular processes responsible for these metabolic disorders. Here is the latest research on aging-associated metabolic disorders.
An autophagosome is the formation of double-membrane vesicles that involve numerous proteins and cytoplasmic components. These double-membrane vesicles are then terminated at the lysosome where they are degraded. Discover the latest research on autophagosomes here.
The feed focuses on the role of nuclear export inhibitors and their effect on autophagy and the aging process.
Autophagy is an important cellular process for normal physiology and both elevated and decreased levels of autophagy are associated with disease. Here is the latest research.
Autophagy preserves the health of cells and tissues by replacing outdated and damaged cellular components with fresh ones. In starvation, it provides an internal source of nutrients for energy generation and, thus, survival. A powerful promoter of metabolic homeostasis at both the cellular and whole-animal level, autophagy prevents degenerative diseases. It does have a downside, however--cancer cells exploit it to survive in nutrient-poor tumors.
Autophagy is a lysosomal pathway that involves degradation of proteins and functions in normal growth and pathological conditions, through a series of complex networks. The catabolic process involves delivery of proteins and organelles to the lysosome. Here is the latest research on autophagy networks.
Here is the latest research on intrinsic and extrinsic factors, as well as pathways and mechanisms that underlie aging in the central nervous system.
This feed focuses on cellular aging with emphasis on mitochondria, autophagy, and metabolic processes associated with aging and longevity. Here is the latest research on cell aging.
