Nrf2 is active protein presents in the cytoplasm cells of body. In presence an activators, can enter nucleus which bind to Antioxidant Responses Elements (ARE) or otherwise named human ARE (hARE) control whole antioxidants activity cell. Many factors may contribute defective overwhelmed cellular activities for instances aging and damages. These damages be produced by free radicals oxidative str...

Oxidative stress is critically involved in a variety of diseases. Reactive oxygen species (ROS) are highly toxic molecules that are generated during the body's metabolic reactions and can react with and damage some cellular molecules such as lipids, proteins, or DNA. Liver is an important target of the oxidative stress because of its exposure to various prooxidant toxic compounds as well as of ...

Background: Ionizing radiation causes deleterious effects on living system mainly due to oxidative damages of macromolecules and protein is the major target due to its abundance. The aim of this study was to investigate the effects of ionizing radiation induced changes in the molecular properties of bovine serum albumin (BSA) its secondary and tertiary structures, degradation, cross linking and...

Echinacoside is a natural compound with potent reactive oxygen species (ROS)-scavenging and anti-oxidative bioactivities, which protect cells from oxidative damages. As cancer cells are often under intense oxidative stress, we therefore tested if Echinacoside treatment would promote cancer development. Surprisingly, we found that Echinacoside significantly inhibited the growth and proliferation...

Ultraviolet-B radiation (285-320 nm) elicits a number of cellular signaling elements. We investigated the preventive effect of linalool, a natural monoterpene, against UVB-induced oxidative imbalance, activation of mitogen-activated protein kinase (MAPK) and nuclear factor kappa-B (NF-κB) signaling in HDFa cells. We observed that linalool treatment (30 μM) prevented acute UVB-irradiation (20 mJ...
