Oxidative stress occurs when cellular reactive oxygen species levels exceed the self-
antioxidant capacity of the body. Oxidative stress induces many pathological changes …

Oxidative stress is caused by an imbalance of reactive oxygen species (ROS)/reactive
nitrogen species (RNS) and the antioxidative stress defense systems in cells. ROS/RNS or …

Oxidative stress has been implicated in various pathological conditions including cancer.
However, the human body has an intrinsic ability to fight against oxidative stress. A wide …

Excessive oxidative stress induced by reactive oxygen species (ROS), reactive nitrogen
species (RNS), and reactive metabolites of carcinogens alters cellular homeostasis, leading …

A precise regulation of redox balance is required for the cellular homeostatic control.
Aberrant activation of redox-sensitive transcription factors, such as nuclear factor-kappaB …

Interest in dietary phytochemicals for potential cancer chemoprevention has increased
substantially. Screening dietary compounds for chemopreventive activity however, requires …

The influence of diet and environment on human health has been known since ages. Plant-
derived natural bioactive compounds (phytochemicals) have acquired an important role in …

Reactive metabolites from carcinogens and oxidative stress can drive genetic mutations,
genomic instability, neoplastic transformation, and ultimately carcinogenesis. Numerous …

Despite extensive studies in cancer prevention, the incidence of cancer is increasing. We
review studies that have identified several biochemical and genetic defects as well as …

BACKGROUND: One of the potential strategies for preventing cancers is using food-based
natural products to induce cytoprotective enzymes including phase II and antioxidative …
