UV-induced photo skin aging is primarily mediated via generation of reactive oxygen species/free radicals. Free radical theory of aging and skin aging is one of the most common causes of chronological and photo skin aging. UV irradiation not only activate … Continue reading
The primary mechanism of UV induced skin aging is the production and generation of reactive oxygen species (ROS). ROS/free radicals is one of the main causes of chronologic and photo skin aging. ROS damages and oxidizes biomacromolecules and cellular components. … Continue reading
The primary mechanism of UV-induced skin aging is mediated by the generation and accumulation of free radicals including reactive oxygen species (ROS) and reactive nitrogen species (RNS). ROS or free radicals not only can damage proteins, DNA, cellular membrane and … Continue reading
The primary mechanism of UV induced skin aging is the production and generation of reactive oxygen species (ROS). ROS/free radicals is one of the main causes of chronologic and photo skin aging . ROS exerts aging effect via damaging and … Continue reading
The free radical theory of aging established the role of oxidative stress as one of the main causes of aging and skin aging. Reactive oxygen species (ROS) – produced as byproduct of oxidative energy metabolism and induced by external factors … Continue reading
Mitochondria are cellular organelles that produce energy (ATP) by consuming oxygen. In the chronological aging process, mitochondria not only produce less ATP, but they also increase the production of reactive oxygen species (ROS) as by-products of aerobic metabolism, particularly during … Continue reading
The molecular signaling pathways associated with skin aging is most and initially studied in the photo skin aging. Numerous researches published combined the pieces of discovery into an general overview picture about what occurred molecularly in photo skin aging. It … Continue reading
The activator protein 1 (AP-1) is a heterodimeric transcription factor belonging to the c-Fos, c-Jun, ATF and JDP families. It regulates and activates genes in response to a variety of stimuli including stress, pathogen infections, cytokines, growth factors. AP-1 thereby … Continue reading
