UV, stress and aging

Skin is a model of choice in studies on aging. Indeed, skin aging can be modulated by internal and external factors, reflecting its complexity. Two types of skin aging have been identified: intrinsic, mainly genetically determined and extrinsic-also called "photo-aging"-resulting on the impact of environmental stress and more precisely of UV rays. Simplified in vitro models, based on cellular s...

Aging and oxidative stress.

The scientific establishment has been discussing the relationship between aging and oxidative stress for quite some time now. While we are still far from a general agreement about this subject, there is an impressive amount of data collected that can be used to draw a compelling picture of the events that take place during the human aging process and their correlation with the oxidant status of...

Stress and aging.

Aging and glycoxidant stress.

Aging and related diseases are accompanied by increased Oxidative Stress (OS) and accumulation of Advanced Glycation End products (AGEs). One important component of AGEs accumulation with aging appears to be the sustained exposure to dietary AGE (dAGEs), which contributes to overloading of anti-AGE receptors and depletion of anti-oxidant reserves. In this review, we present experimental animal ...
