The "Two-Faced" Effects of Reactive Oxygen Species and the Lipid Peroxidation Product 4-Hydroxynonenal in the Hallmarks of Cancer
نویسندگان
چکیده
Reacytive Oxygen Species (ROS) have long been considered to be involved in the initiation, progression and metastasis of cancer. However, accumulating evidence points to the benefical role of ROS. Moreover, ROS production, leading to apoptosis, is the mechanism by which many chemotherapeutic agents can act. Beside direct actions, ROS elicit lipid peroxidation, leading to the production of 4-hydroxynoneal (HNE). Interestingly, HNE also seems to have a dual behaviour with respect to cancer. In this review we present recent literature data which outline the "two-faced" character of oxidative stress and lipid peroxidation in carcinogenesis and in the hallmarks of cancer.

متن کاملO-13: Evaluation of Leptin Concentration in Seminal Plasma and Its Correlation with Reactive Oxygen Species, Lipid Peroxidation and Pronuclear Formation in Candidates for ICSI Treatment
Background Leptin, as a key hormone in energy homeostasis, plays an important role in reproduction and male fertility. However, its negative or positive effect on sperm quality and assisted reproduction technique is still controversial. The aim of this study was the comparison of seminal leptin concentration in selected couples with male and female factor for intracytoplasmic microinjection (IC...
متن کاملGrowth modulation of human cells in vitro by mild oxidative stress and 1,4-dihydropyridine derivative antioxidants.
Reactive oxygen species and lipid peroxidation products are not only cytotoxic but may also modulate signal transduction in cells. Accordingly, antioxidants may be considered as modifiers of cellular redox signaling. Therefore, the effects of two novel synthetic antioxidants, analogues of 1,4-dihydropyridine derivatives, cerebrocrast and Z41-74 were analysed in vitro on human osteosarcoma cell ...
متن کاملIron Overload Induced Apoptotic Cell Death in Isolated Rat Hepatocytes Mediated by Reactive Oxygen Species
Isolated rat hepatocytes in culture were incubated with different concentrations of iron-sorbitol (50, 100, 150, and 200 µM) to assess the changes in reactive oxygen species (ROS) and lipid peroxidation leading to apoptotic hepatocyte cell death. The viability of hepatocytes was declined depending on the iron concentration. One hour incubation of the cells with 100 µM iron resulted in decreased...
