ROS, stress-activated kinases and stress signaling in cancer.
Anticancer therapy is frequently efficient in early stages of the disease, whereas advanced tumors are usually resistant to the same treatments. The molecular basis for this change is not entirely understood. Many anticancer agents are DNA- or cytoskeleton-damaging drugs that show some specificity towards dividing cells. However, recent studies show that these agents also activate stress-signal...
متن کاملPhytohormones Signaling Pathways and ROS Involvement in Seed Germination
Phytohormones and reactive oxygen species (ROS) are major determinants of the regulation of development and stress responses in plants. During life cycle of these organisms, signaling networks of plant growth regulators and ROS interact in order to render an appropriate developmental and environmental response. In plant's photosynthetic (e.g., leaves) and non-photosynthetic (e.g., seeds) tissue...
متن کاملROS signaling pathways and biological rhythms: perspectives in crustaceans.
This work reviews concepts regarding the endogenous circadian clock and the relationship between oxidative stress (OS), light and entrainment in different organisms including crustaceans, particularly crayfish. In the first section, the molecular control of circadian rhythms in invertebrates, particularly in Drosophila, is reviewed, and this model is contrasted with recent reports on the circad...
متن کاملROS Function in Redox Signaling and Oxidative Stress
Oxidative stress refers to elevated intracellular levels of reactive oxygen species (ROS) that cause damage to lipids, proteins and DNA. Oxidative stress has been linked to a myriad of pathologies. However, elevated ROS also act as signaling molecules in the maintenance of physiological functions--a process termed redox biology. In this review we discuss the two faces of ROS--redox biology and ...
متن کاملRos Signaling in Plants
The evolution of aerobic metabolism such as respiration and photosynthesis resulted in the generation of reactive oxygen species (ROS). A common property of all ROS types is that they can cause oxidative damage to proteins, DNA, and lipids. This toxicity of ROS explains the evolution of complex arrays of nonenzymatic and enzymatic detoxification mechanisms in plants. However, increasing evidenc...
