O 22: Reactive Oxygen Species and Epilepsy
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

متن کاملEffect of Hesperetin on the level of reactive oxygen species (ROS) in gastric cancer stem cells: Short Communication
Intracellular reactive oxygen species (ROS) play an important role in cancer stem cell (CSC) function. Hesperetin (Hst) is a flavonoid that has been shown to affect cellular ROS level. The goal of this study was to investigate the effect of Hst on the level of ROS in gastric CSCs (GCSCs). MTT assay was used to evaluate cell survival. Cellular ROS level was measured using 2′,7′-dichlorofluoresci...
متن کاملMitochondrial reactive oxygen species and cancer
Mitochondria produce reactive oxygen species (mROS) as a natural by-product of electron transport chain activity. While initial studies focused on the damaging effects of reactive oxygen species, a recent paradigm shift has shown that mROS can act as signaling molecules to activate pro-growth responses. Cancer cells have long been observed to have increased production of ROS relative to normal ...
متن کاملModulation of reactive oxygen species in pancreatic cancer.
PURPOSE The aim of the present study was to compare the effects of the three different forms of the antioxidant enzyme superoxide dismutase [i.e., manganese superoxide dismutase (MnSOD), copper zinc superoxide dismutase (CuZnSOD), and extracellular superoxide dismutase (EcSOD)] on the malignant phenotype of human pancreatic cancer. EXPERIMENTAL DESIGN Human pancreatic cancer cell lines were i...
